Answer:
Imagination is more important than knowledge. --Clifford big red dog
Step-by-step explanation:
a) To find the average cost per pair of shoes, we need to divide the total cost by the number of pairs produced. Since the manufacturer produced x pairs of shoes, the total cost is 12,000+19x dollars. Therefore, the average cost per pair is given by:
Average cost per pair = (12,000+19x) / x
b) Using the given information that this month, the manufacturer produced 1000 more pairs of shoes than last month, we can represent the number of pairs produced last month as x−1000. Since the average cost per pair dropped by $0.43, the equation representing the situation is:
(12,000+19(x)−43(x)) / x=Average cost per pair
Solving this equation will provide us with the value of x.
c) Yes, there is a mathematical restriction on the domain. Since the number of pairs produced cannot be negative (it doesn't make sense to produce a negative number of shoes), the domain must be restricted to x>0.
d) In the context of the problem, the reasonable domain would be x>0 since the number of pairs of shoes produced cannot be negative. Additionally, since the manufacturer produced 1000 more pairs of shoes this month than last month, it's reasonable to assume that the number of pairs produced last month is also positive, leading to a positive change of 1000 pairs. Therefore, the domain would be x>1000.
a) The expression for the average cost per pair of shoes is given by:
Average cost per pair = (12,000+19x) / x
To represent the situation, we use this expression to equate the average cost per pair before and after the change in production.
b) Substituting x+1000 for x in the expression, we get:
(12,000+19(x+1000)) / (x+1000) = Average cost per pair
We solve this equation to find the value of x.
c) Yes, there's a restriction on the domain. Since the number of pairs of shoes cannot be negative, the domain must be x>0.
d) Considering the context, the reasonable domain is x>1000, as the manufacturer produced 1000 more pairs this month than last month. Also, x must be positive, so x>0. Thus, the domain is x>1000.
Complete Question:
The cost in dollars to manufacture x pairs of shoes is given by 12,000 + 19x. This month, the manufacturer produced 1000 more pairs of shoes than last month. The average cost per pair dropped by $0.43.

plus I checked the answer after I got it wrong so...
Answer:
[tex]\frac{1}{9}[/tex]
Step-by-step explanation:
This is a case of enlargement of a figure of scale factor [tex]\frac{1}{3}[/tex].
In any enlargement, [tex]Area(F')=k^2 Area(F)[/tex], where the transformation maps F onto F'.
In this case, let F be polygon XXX and let F' be polygon YYY. Hence,
[tex]Area(YYY) = k^2 Area (XXX)[/tex]
[tex]Area(YYY) = (\frac{1}{3})^2 Area(XXX)[/tex]
[tex]Area(YYY) = \frac{1}{9} Area(XXX)[/tex]
Therefore, the area of polygon YYY is [tex]\frac{1}{9}[/tex] of the area of polygon XXX.

A 95-foot wire attached from the top of a cell phone tower makes a 62 degree angle with the ground. Joey is standing 150 feet behind the wire, looking up at the tower. Find the angle of elevation from the point on the ground where Joey is standing to the top of the tower.
Answer:
23.32 degrees
Step-by-step explanation:
We set up a large right triangle that has 2 triangles within it. The large triangle is a right triangle. The height of it is the height of the tower, the base angle is 62, the hypotenuse is 95, and the base measure is y. The other triangle has the same height which is the height of the tower, the angle is what we are looking for, and the base measure is 150 feet beyond y, so its measure is y + 150. We have enough information to find the height of the tower, so let's do that first. Going back to the first smaller triangle.
[tex]sin62=\frac{x}{95}[/tex] so the height of the tower is 83.88 feet. Now we need to solve for y. Using that same triangle and the tangent ratio, we find that [tex]tan62=\frac{83.88}{y}[/tex]. Now let's do the same thing for the other triangle with the unknown angle.
[tex]tan\beta =\frac{83.88}{y+150}[/tex]
Solve both of these for y. The first one solved for y:
[tex]y=\frac{83.88}{tan62}[/tex]
The second one solved for y will simplify to:
[tex]y=\frac{83.88-150tan\beta }{tan\beta }[/tex]
Now that these are both solved for y, and y = y, we can set them equal to each other by the transitive property of equality:
[tex]\frac{83.88-150tan\beta }{tan\beta }=\frac{83.88}{tan62}[/tex]
Cross multiply to get this big long messy looking thing:
[tex]tan62(83.88-150tan\beta )=83.88tan\beta[/tex]
Distribute through the parenthesis to get
[tex]83.88tan62-[(tan62)(150tan\beta)]=83.88tan\beta[/tex]
Get the unknown angles on the same side so it can be factored out:
[tex]83.88tan62=83.88tan\beta +[(tan62)(150tan\beta )][/tex]
And then factoring it out gives you:
[tex]83.88tan62=tan\beta(83.88+150tan62)[/tex]
Divide to get
[tex]tan\beta =\frac{83.88tan62}{83.88+150tan62}[/tex]
Do this on your calculator in degree mode to give you an angle measure of 23.32°. I know this is really hard to follow without being able to draw the pics for you like I do in my classroom, but hopefully you can follow my description and draw your own triangles and follow from that!
An angle of elevation is formed by two reference lines; the horizontal line and the line from the reference point to the point in view
The angle of elevation from the point on the ground where Joey is standing to the top of the tower is approximately 23.318°
Reason:
Given parameter;
Length of the wire = 95 ft.
Angle formed by the wire and the ground = 62°
Location Joey is standing behind the wire, L = 150 feet
Required:
The angle of elevation from the ground at the point where Joey is standing to the top of the tower
Solution:
The height of the tower, h = 95 × sin(62°) ≈ 83.88 feet
Distance of the tower to the point the wire touches the ground, d, is given as follows;
d = 95 × sin(62°) ≈ 44.6 ft.
The distance of of Joey from the base of the tower, D = L + d
D = 150 ft. + 44.6 ft. = 194.6 ft.
Distance of Joey from the base of the tower, D = 194.6 ft.
Let θ represent the angle of elevation from the point on the ground where Joey is standing to the top of the tower, we have;
[tex]tan(\theta ) = \dfrac{h}{D}[/tex]
Therefore;
[tex]\theta = arctan \left(\dfrac{h}{D} \right)[/tex]Which gives;
[tex]\theta = arctan \left(\dfrac{83.88}{194.6} \right) \approx 23.318^{\circ}[/tex]The angle of elevation from the point on the ground where Joey is standing to the top of the tower, θ ≈ 23.318°

Find the values of x and y when the smaller triangle shown here has the given area.
The values of x and y, when the smaller triangle has an area of 10 cm² are x = 4cm and y = 5cm.
Explanation:In the given triangle, the area can be expressed as [tex]\( \frac{1}{2} \times x \times y \)[/tex], where x and y represent the base and height of the triangle, respectively. Since the area is given as 10 cm², the equation becomes [tex]\( \frac{1}{2} \times x \times y = 10 \)[/tex].
To find x and y, we can rearrange the equation:
[tex]\[ x \times y = \frac{10 \times 2}{1} \][/tex]
[tex]\[ x \times y = 20 \][/tex]
Now, we need to find two numbers whose product is 20. The pair x = 4 and y = 5 satisfies this condition, as 4 × 5 = 20. Therefore, the values of x and y that satisfy the given area are x = 4cm and y = 5cm.
In conclusion, the solution x = 4cm and y = 5cm satisfies the given area condition. This is determined by substituting these values into the area formula, resulting in an area of 10 cm².
Antoine has $18.20 to spend on some oranges and a pumpkin. Oranges cost
$1.30 per pound, and a pumpkin costs $5.20
The inequality 1.30x + 5.20 18.20 models this situation, where x is the
number of pounds of oranges.
Solve the inequality. How many pounds of oranges can Antoine buy?
Answer:
10 pounds
Step-by-step explanation:
You forgot the inequality sing, but since Antoine can't spend more than $18.20, I am positive that the sign is [tex]\leq[/tex] (Antony can spend $18.20 or less than $18.20).
Therefore, our inequality is: [tex]1.30x+5.20\leq 18.20[/tex]
where [tex]x[/tex] is the pounds of oranges
Let's solve step-by-step to find how many pounds of oranges he can buy
Step 1. Subtract 5.20 fro both sides of the inequality
[tex]1.30x+5.20-5.20\leq 18.20-5.20[/tex]
[tex]1.30x\leq 13[/tex]
Step 2. Divide both sides of the inequality by 1.30
[tex]\frac{1.30x}{1.30} \leq \frac{13}{1.30}[/tex]
[tex]x\leq 10[/tex]
We can conclude that Antony can buy 10 pounds of oranges.

- Lets take the denominator and simplify by make it a single
fraction, let the denominator of it 2x and change
the numerator
∴ [tex]\frac{x^{2}}{2}+\frac{2}{x}=\frac{x(x^{2})+2(2)}{(2)(x)}=\frac{x^{3}+4}{2x}[/tex]
∴ The fraction = [tex]\frac{\frac{3x-7}{x^{2}}}{\frac{x^{3}+4}{2x}}[/tex]

∴ [tex]\frac{3x-7}{x^{2}}[/tex] ÷ [tex]\frac{x^{3}+4}{2x}[/tex]
- Change the division sign to multiplication sign and reciprocal
the fraction after the sign
∴ [tex]\frac{3x-7}{x^{2}}[/tex] × [tex]\frac{2x}{x^{3}+4}[/tex]
∴ [tex]\frac{(2x)(3x-7)}{(x^{2})(x^{3}+4)}[/tex]

What do you call the answer to a subtraction problem
Answer:
Difference
Step-by-step explanation:
Remember that the therms of any subtraction problem are minuend, subtrahend, and difference.
- The minuend is the number from which you subtract something. For example, in the subtraction problem 4 -3 = 1, 4 is the minuend (you are subtracting 3 form it).
- The subtrahend is the number you subtract (from the minuend). For example, in 4 - 3 = 1, 3 is the subtrahend (you are subtracting 3 from the minuend 4).
- The difference is the result of subtracting the subtrahend form the minuend, in other words, the result of the subtraction problem. For example, in 4 - 3 = 1, 1 is the difference (the result)
We can conclude that the result of a subtraction problem is called the difference.
. In mathematics, the answer to a subtraction problem is called the difference.
For example, when you subtract 3 from 5, you perform the following calculation:
5 - 3 = 2
Here, 2 is the difference. Similarly, if you subtract -6 from 2, you change the sign of the number being subtracted and then add:
2 - (-6) = 2 + 6 = 8
The answer, 8, is the difference as well.
The concept of difference holds true for both scalar and vector quantities. For both types, the difference is the result of the subtraction operation.

A. The frequency is 1 fewer than expected
B. The frequency is 9 fewer than expected
C. The frequency is 2 more than expected
D. The frequency is the same as expected
Answer:
A
Step-by-step explanation:
You take the number of shirts you have and are focusing on. In this case concert (12) and divide it by the total number of shirts to get the expected.
You can use the fact when random picking of t shirts happen, the probability of picking the Concert shirt can be taken by number of concert t shirts in total number of shirt since there is no bias towards a particular t shirt except their frequency.
The frequency of concert shirts obtained out of selected shirts compare to the expected frequency of the concert shirt as:
Option A: The frequency is 1 fewer that expected.
How to get the expected frequency of the object from the whole group?Suppose there are 100 fruits and 50 of them are apples and 50 other are mangoes. Then we can say that each one of the two fruit is apple and other one is mango. This 1 apple per 2 fruit is telling frequency of apples in selected 2 fruits.
Frequency is number of amount that item is present in the selected group.
The expected frequency can be obtained by seeing how many such objects are available to how many total objects.
You can think of expected frequency as how many of the considered object we expect to be present in the total amount of objects.
Thus, we have:
Expected frequency for concert shirt is 12 per 30 shirts or 4 per 10( i divided by 3) shirts or 2 per 5 shirts ( divided by 2). You can convert this to percent or probability too or ratio too like
2:5 = 2/5 = 0.4 = 40% (all four represent how many of the concert shirts are expected to be present out of amount of total shirts selected).
The frequency obtained from the selection contains 3 concert shirts out of 10 selected shirts.
Since the expected frequency of the concert shirts per 10 shirts selected is 4, and the frequency we obtained is 3, thus. the frequency obtained is 1 fewer than the expected.
Thus,
Option A: The frequency obtained is 1 fewer than expected.

The area of a right triangle with side lengths 7 and 7 is [tex]\frac{bh}{2} = \frac{7*7}{2} = \frac{49}{2} = 24.5[/tex]
Answer: ≈ 13.98 in2
Step-by-step explanation:
A segment of a circle is a region bounded by an arc and its chord.
To determine the area of the segment, begin by finding the area of the sector defined by the central angle.
A sector of a circle is a region bounded by two radii of the circle and their intercepted arc.
The formula for the sector area is A = πr2 (m∘/360∘).
It is given in the figure that central angle MNO is a right angle. So, m∠MNO = 90∘. It is also given that r = 7 in.
Substitute the given values into the formula and simplify.
A = π(7)2 (90∘/360∘) = 49/4π in2
Find the area of △MNO.
Since the radii in a circle are congruent, NO = NM = 7. To find the area of △MNO, use the formula for the area of a triangle, A = 1/2bh.
Substitute 7 for b and 7 for h, then simplify.
A = 1/2 (7) (7) = 24.5 in2
The area of the segment is the difference between the two areas, the area of the sector and the area of the triangle.
A = 49/4π − 24.5 ≈ 13.98 in2
Therefore, the area of segment MNO is ≈ 13.98 in2.

Step-by-step explanation:
Madame Pickney has a rather extensive art collection and the overall value of her collection has been increasing each year. Three years ago, her collection was worth $600,000. Two years ago, the value of the collection was $690,000 and last year, the collection was valued at $793,500.
Assume that the rate at which Madame Pickney’s art collection’s value increase remains the same as it has been for the last three years. The value of the art collection can be represented by a geometric sequence. The value of the collection three years ago is considered the first term in the sequence.
What explicit rule can be used to determine the value of her art collection n years after that?
Answer:
an = 600,000 (1.15)^(n-1)
Step-by-step explanation:
So the first year, a₁ = 600,000. The next year, a₂ = 690,000. So:
r = a₂ / a₁
r = 690,000 / 600,000
r = 1.15
So an = 600,000 (1.15)^(n-1).
Your answer is correct!

Answer:
w = 93°
Step-by-step explanation:
The angle with measure 142° forms a straight angle with the third angle in the triangle and are supplementary, thus
third angle = 180° - 142° = 38°
The sum of the 3 angles in the triangle = 180°
w = 180° - (38 + 49)° = 180° - 87° = 93°

88.2Step-by-step explanation:
(look at the picture)
We have opposite and adjacent. Therefore we must use the tangent:
[tex]\tangent=\dfrac{opposite}{adjacent}[/tex]
[tex]adjacent=500\\opposite=x\\\tan10^o\approx0.1763[/tex]
Substitute:
[tex]\dfrac{x}{500}\approx0.1763[/tex] multiply both sides by 500
[tex]x\approx88.15\to x\approx88.2[/tex]

In triangle STU, UT=5 and angleS=21. Find SU to the nearest tenth
The answer is:
The second option,
[tex]SU=13.02=13[/tex]
Why?We are working with a right triangle, it means that we can use the following trigonometric property:
[tex]Tan(\alpha)=\frac{Opposite}{Adjacent}[/tex]
Which applied to our problem, will be:
[tex]Tan(\alpha)=\frac{TU}{SU}[/tex]
We are given:
m∠S, equal to 21°
The side TU (opposite) equal to 5 units.
So, substituting and calculating we have:
[tex]SU=\frac{TU}{Tan(\alpha)}[/tex]
[tex]SU=\frac{5units}{Tan(21\°)}[/tex]
[tex]SU=13.02=13[/tex]
Hence, the answer is the second option
[tex]SU=13.02=13[/tex]
Have a nice day!
Answer:
13.0
Step-by-step explanation:
The given angle is m<S=21.
The given side length UT=5 units.
This side length is opposite to the given angle.
Since we want to find SU, the adjacent side; we use the tangent ratio to obtain;
[tex]\tan 21\degree=\frac{opposite}{adjacent}[/tex]
[tex]\tan 21\degree=\frac{5}{SU}[/tex]
This implies that;
[tex]SU=\frac{5}{\tan 21\degree}[/tex]
Therefore SU=13.025

One number is 4 times a first number. A third number is 100 more than the first number. If the sum of the three numbers is 538, find the numbers
Answer:
73
292
173
Step-by-step explanation:
x = first number
4x = second number
100 + x = third number
x + 4x + 100 + x = 538
6x + 100 = 538
6x + 100 - 100 = 538 - 100
6x = 438
6x/6 = 438/6
x = 73
Check:
73 + 4(73) + 100 + 73 = 538
73 + 292 + 173 = 538
538 = 538
Answer:
The numbers are 73, 173 and 292.
Step-by-step explanation:
If the numbers are x, y and z we have:
y = 4x
z = x + 100
x + y + z = 538
Substituting for y in the last equation:
x + 4x + z = 538
5x + z = 538.............(1)
From the second equation:
z - x = 100................(2)
Equation (1) - (2) gives:
6x = 438
x = 73
Therefore y = 4x) = 4(73) = 292
and z = x + 100 = 73 + 100 = 173.
