Answer:
He will earn $81 in 12 hours.
Step-by-step explanation:
Given:
Teo earns 47.25$ in 7 hours of work at Beck’s Burgers.
Now, to find the money he will earn in 12 hours.
As, given Teo earns 47.25$ in 7 hours of work.
So, to get the money he will earn in 12 hours we solve by using unitary method:
If Teo earns in 7 hours $47.25.
Then, in 1 hour he earns = [tex]\frac{47.25}{7}[/tex]
Thus, in 12 hours he will earn = [tex]\frac{47.25}{7} \times 12[/tex]
= [tex]6.75\times 12[/tex]
= [tex]\$81.[/tex]
Therefore, he will earn $81 in 12 hours.

The length of a rectangle is 3 1/6 cm longer than the width. The perimeter of the rectangle is 15 1/3 cm. What are the width and length of this rectangle?
The width of rectangle is [tex]2\frac{1}{4}\ cm[/tex] and length is [tex]5\frac{5}{12}\ cm[/tex]
Step-by-step explanation:
Let,
Width of rectangle = w
Length of rectangle = w+[tex]3\frac{1}{6}=w+\frac{19}{6}[/tex]
Perimeter of rectangle = [tex]15\frac{1}{3}=\frac{46}{3}\ cm[/tex]
Perimeter of rectangle = 2(Length + Width)
[tex]2(w+\frac{19}{6}+w)=\frac{46}{3}\\2(2w+\frac{19}{6})=\frac{46}{3}\\4w+\frac{19}{3}=\frac{46}{3}[/tex]
Subtracting [tex]\frac{19}{3}[/tex] from both sides
[tex]4w+\frac{19}{3}-\frac{19}{3}=\frac{46}{3}-\frac{19}{3}\\4w=\frac{46-19}{3}\\4w=\frac{27}{3}\\4w=9[/tex]
Dividing both sides by 4
[tex]\frac{4w}{4}=\frac{9}{4}\\w=\frac{9}{4}[/tex]
Therefore,
Width of rectangle = w = [tex]\frac{9}{4}=2\frac{1}{4}[/tex] cm
Length of rectangle = [tex]w+\frac{19}{6}=\frac{9}{4}+\frac{19}{6}=\frac{27+38}{12}=\frac{65}{12}=5\frac{5}{12}\ cm[/tex]
The width of rectangle is [tex]2\frac{1}{4}\ cm[/tex] and length is [tex]5\frac{5}{12}\ cm[/tex]

a_{n}=-17-9(n-1)a
n
=−17−9(n−1)
Answer:
The nth term of the given arithmetic sequence is [tex]a_n=-17+(n-1)9[/tex]
Step-by-step explanation:
Given sequence is -17,-8,1,...
To find the nth term of the given sequence :
Let [tex]a_1=-17,a_2=-8,a_3=1,...[/tex]
To find the common difference d :
[tex]d=a_2-a_1[/tex]
[tex]=-8-(-17)[/tex]
[tex]=-8+17[/tex]
Therefore d=9
[tex]d=a_3-a_2[/tex]
[tex]=1-(-8)[/tex]
[tex]=1+8[/tex]
Therefore d=9
The common difference d is 9
Therefore the given sequence is an arithmetic sequence
The nth term of an arithmetic sequence is given below
[tex]a_n=a_1+(n-1)d[/tex]
Substitute [tex]a_1=-17[/tex] and d=9 in the above equation we get
[tex]a_n=-17+(n-1)9[/tex]
Therefore the nth term of the given arithmetic sequence is [tex]a_n=-17+(n-1)9[/tex]
The formula for the nth term of the sequence -17, -8, 1 is a_n = 9n - 26, where n is the position of the term in the sequence.
Explanation:The sequence provided is -17, -8, 1, which suggests that there is a common difference between terms since it is an arithmetic sequence. To find the nth term of an arithmetic sequence, we use the formula a_n = a_1 + (n - 1)d, where a_n is the nth term, a_1 is the first term, and d is the common difference. In this case, the common difference is 9 (since -8 - (-17) = 9).
So, using the formula for the nth term of an arithmetic sequence:
a_1 = -17 (the first term)d = 9 (the common difference)Our formula becomes a_n = -17 + (n - 1) × 9. Simplifying this:
a_n = -17 + 9n - 9
a_n = 9n - 26
Therefore, the formula for the nth term of the given sequence is a_n = 9n - 26.

Question 3
Answer: Choice A) {(3,4) (3,5)}-----------
Explanation:
Note how in choice A we have repeated x values
x = 3 pairs up with y = 4 and y = 5 at the same time.
The input x = 3 must only pair up with one output only if we want a function to happen.
If you plotted the points (3,4) and (3,5), it is possible to draw a vertical line through them. So this fails the vertical line test.
The other answer choices do not have repeated x values, so they are all functions.
==========================================
Question 4
Answer: choice A) 2x+3y = 10 and choice D) y = 18-----------
If you plotted choice A and choice D on an xy coordinate system, you should see straight lines forming.
2x+3y = 10 turns into y = (-2/3)x+10/3 which is y = mx+b form.
Choice D's equation is equivalent to y = 0x+18, so its slope here is 0, making it a flat horizontal line.
Choice B does not count as an answer because while it is a linear vertical line, it is not a function for similar reasons back in question 3. The fact that x = 16 pairs up with infinitely many y values is what makes this not be a function.
Choice C is not a linear equation. Instead it is a quadratic equation because the largest exponent is 2.

Use the triangle inequality theorem to determine the smallest angle in the figure.
ZSCI
ZCIS
ZCSI
Lisc
Answer:
∠CIS.
Step-by-step explanation:
This angle is opposite from the smallest side. Therefore, according to the triangle inequality, it is the smallest angle.
The smallest angle that the angular momentum vector can make with the z-axis for an electron with quantum number l=2 is found using the magnetic quantum numbers. For m₁=+2, the angle would be the smallest, approaching 0 degrees.
Explanation:The question pertains to the calculation of the smallest angle that the angular momentum vector ℓ can make with the z-axis given the quantum number l for an electron. To find this, we use the concept of quantized angular momentum in quantum mechanics.
For an electron with a quantum number l=2, it can have multiple magnetic quantum numbers m₁, ranging from -l to +l. Therefore, for l=2, m₁ can be -2, -1, 0, 1, or 2. Each of these values corresponds to a different angle with the z-axis.
The smallest angle corresponds to the maximum value of m₁, which is 2 in this case. The formula cos 0 = Lz/L uses the magnetic quantum number m₁ and the total angular momentum to calculate the cosine of the angle. For m₁=+1, the value of cos 0 would be 0.707, using the provided ratios and simplifying the formulas given. This corresponds to an angle whose cosine is 0.707, which through the inverse cosine function can be determined to be approximately 45 degrees. However, for m₁=+2, the angle would be even smaller, approaching 0 degrees as the z-component of angular momentum becomes maximally aligned with the z-axis.
7. The sun is at an angle of elevation of 58º. A tree casts a shadow 20 meters long on
the ground. How tall is the tree?
The height of tree is 32 meter
Solution:
Given that, The sun is at an angle of elevation of 58 degree
A tree casts a shadow 20 meters long on the ground
The sun, tree and shadow forms a right angled triangle
The figure is attached below
ABC is a right angled triangle
AC is the height of tree
AB is the length of shadow
AB = 20 meters
Angle of elevation, angle B = 58 degree
By definition of tan,
[tex]tan \theta = \frac{opposite}{adjacent}[/tex]
In this right angled triangle ABC,
opposite = AC and adjacent = AB
Therefore,
[tex]tan\ 58 = \frac{AC}{AB}\\\\tan\ 58 = \frac{AC}{20}\\\\1.6 = \frac{AC}{20}\\\\AC = 1.6 \times 20\\\\AC = 32[/tex]
Thus height of tree is 32 meter
Final answer:
To determine the height of the tree using the angle of elevation of the sun and the shadow length, apply the tangent function. With an elevation of 58º and a shadow of 20 meters, the tree’s height is calculated to be approximately 33.94 meters.
Explanation:
To find the height of the tree given the angle of elevation of the sun and the length of the shadow it casts, we can make use of trigonometry. Specifically, we will use the tangent function, which relates the angle of elevation with the opposite side (the height of the tree) and the adjacent side (the length of the shadow).
Step-by-step solution:
Let's denote the height of the tree as H and the length of the shadow as 20 meters.The angle of elevation of the sun is given as 58º.Using the tangent function: tan(θ) = opposite/adjacent, where θ is the angle of elevation.Plugging in the values, we get tan(58º) = H / 20 meters.Solve for H by multiplying both sides by 20 meters: H = 20 meters · tan(58º).Use a calculator to find tan(58º), and then compute H.After calculating, we find that the height of the tree is approximately 33.94 meters.Thus, the height of the tree is approximately 33.94 meters.

On average shawnte drinks 1/2 of a 6-ounce glass of water in 2/3 hour how much watee does she drink in a hour
she drinks 9/2 ounces of water in 1 hour
Step-by-step explanation:
On average, the person drinks 1/2 of a 6-ounce glass of water in 2/3 hour.
First of all, we have to rewrite the amount of water in a single fraction: we have
[tex]\frac{1}{2}\cdot 6 = \frac{6}{2}=3[/tex]
This means that the person drinks 3 ounces of water every 2/3 hours.
In order to find how much water she drinks in one hour, we use the following proportion:
[tex]\frac{3}{2/3}=\frac{x}{1}[/tex]
where
x is the amount of water she drinks in one hour.
Solving the equation for x,
[tex]x=\frac{3\cdot 1}{2/3}=\frac{3\cdot 1 \cdot 3}{2}=\frac{9}{2}[/tex]
Therefore, she drinks 9/2 ounces of water in 1 hour.

the consecutive odd integers have a sum of 36. find the integers
how many consecutive odd integers are there, or else I can't help you
==================================================
Work Shown:
x = some integer
2x = even integer
2x+1 = odd integer
(2x+1)+2 = 2x+3 = odd integer just after 2x+1
The integers 2x+1 and 2x+3 add to 36
(2x+1)+(2x+3) = 36
2x+2x+1+3 = 36
4x+4 = 36
4x+4-4 = 36-4 ... subtract 4 from both sides
4x = 32
4x/4 = 32/4 .... divide both sides by 4
x = 8
With x = 8, we can say
2x+1 = 2*8+1 = 17 is the first odd integer
2x+3 = 2*8+3 = 19 is the next odd integer
17+19 = 36, so the answer is confirmed
--------------------
A non-algebraic way to get the answer is to divide 36 in half to get 18
Then try odd integers around 18, so 19+21 = 40 but thats too high
then maybe try 15+17 = 32, thats too low
17+19 = 36 is right on the money

5x+2y=9
x+y= -3
Answer:
Step-by-step explanation:
5x+2y=9.......(1)
x+y= -3.........(2)
Making y as subject bin (2)
y = -3 - x
Substituting in (1)
5x + 2(-3 - x) = 9
5x - 6 - 2x = 9
3x = 9 + 6
3x = 15
x = 15/3
x = 5
And y = -3 - x
y = -3 - 5
y = -8
Answer:
The solution for the system of linear equations is x = 5, y = -8
Step-by-step explanation:
Let's solve the system of linear equations by substitution:
5x + 2y = 9
x + y = -3
Solving for x in the 1st equation, this way:
5x + 2y = 9
5x = 9 - 2y
x = (9 - 2y)/5
Substituting x in the 2nd equation:
x + y = -3
(9 - 2y)/5 + y = -3
9 - 2y + 5y = - 15 (Multiplying by 5 at both sides)
3y = - 15 - 9
y = -24/3
y = - 8
Substituting y in the 1st equation:
5x + 2y = 9
5x + 2 * - 8 = 9
5x - 16 = 9
5x = 25
x = 25/5 = 5
The solution for the system of linear equations is x = 5, y = -8

A cat weighs 3.5 ounces when born. The cat grows 0.5 ounces each week. After
how many weeks does the cat way 16.5 ounces?
Answer:
10 weeks
Step-by-step explanation:
Answer: 26 weeks
Step-by-step explanation:
This is an example of an arithmetic sequence.
The first term = 3.5
common difference = 0.5
Using the formula for calculating the nth term of an arithmetic sequence :
[tex]t_{n}[/tex] = a + (n - 1 ) d
Therefore :
16.5 = 3.5 + ( n - 1 ) x 0.5
16. 5 = 3.5 + 0.5n - 0.5
16.5 = 3 + 0.5n
16.5 - 3 = 0.5n
13.5 = 0.5n
n = 13.5/0.5
n = 27
Therefore , it will take the cat (n-1) weeks to weigh 16.5 ounce, which will be 27 - 1 = 26
check:
3.5 + 26 ( 0.5)
= 3.5 + 13
= 16.5

The quotient is [tex]\frac{3(y-5)}{2}[/tex]
Explanation:
The expression is [tex]\frac{2 y^{2}-6 y-20}{4 y+12} \div \frac{y^{2}+5 y+6}{3 y^{2}+18 y+27}[/tex]
Now, reciprocal the term [tex]\frac{y^{2}+5 y+6}{3 y^{2}+18 y+27}[/tex] and convert ÷ to ×
[tex]\frac{2 y^{2}-6 y-20}{4 y+12} \times \frac{3 y^{2}+18 y+27}{y^{2}+5 y+6}[/tex]
Taking the common terms out, we get,
[tex]\frac{2\left(y^{2}-3 y-10\right)}{4(y+3)} \times \frac{3\left(y^{2}+6 y+9\right)}{y^{2}+5 y+6}[/tex]
Factorizing each numerator and denominator, we get,
[tex]\frac{2(y-5)(y+2)}{4(y+3)} \times \frac{3(y+3)(y+3)}{(y+3)(y+2)}[/tex]
Multiplying the terms, we have,
[tex]\frac{6(y-5)(y+2)(y+3)^{2}}{4(y+3)^{2}(y+2)}[/tex]
Cancelling the common factors, we get,
[tex]\frac{3(y-5)}{2}[/tex]
Thus, the quotient is [tex]\frac{3(y-5)}{2}[/tex]
