Answer:

Markup rate = 0.512 or 51.2%

Step-by-step explanation:

Mark up rate is the increase amount added to the original price.

Sales Price = $95.98

Original Price= $63.45

Gross profit margin = Sales Price - Original cost

                                = $95.98 - $63.45

                                = $ 32.53

Mark up Rate = Gross profit margin/ original price

                                  = 32.53 / 63. 45

                                  = 0.51

converting into percentage by multiplying with 100

Mark up Percentage = 0.512 * 100

                                  = 51.2 %

Answer:

Well it would come out to 2x-3y=-9

Step-by-step explanation:

Here's how you solve this problem:

1) Multiply the first equation by 2 (result:2x+2y=8).

2) Add both equations together (result:2x+x+2y-2y=8-5)

3) Simplify (result:3x=3)

The answer is 3x=3.

This could be simplified more, however, to equal x=1, since both sides are divisible by 3.

Answer: 45 kilometers

Step-by-step explanation:

The equation to solve this problem is:

$165 = 1.4x + 102

The variable x represents the number of kilometers he travels.

To solve the equation:

Subtract 102 from each side-

63 = 1.4x

Next divide each side by 1.4-

45 = x

Teague needs to run 45 kilometers in order to raise $165.

165=1.40x+102 (equation) x = amount run and final answer is x=45

The answer is 50%.

Divide 2.25 by 1.50. That equals 1.5. That’s the equivalent to 50% because if you subtract 1 from 1.5 and multiply by 100. You get the same answer. Only do that for numbers greater than one, otherwise it won’t work

The approximate probability that there will not be enough vegan meals is 94.88%.

To calculate the approximate probability that there will not be enough vegan meals, we need to find the probability that 18 or more vegans will come to the restaurant. Since the survey showed that approximately 4% of people in the city are vegans, we can use this information to estimate the probability.

First, we find the number of vegans in the city and surrounding area by multiplying the total population by the percentage of vegans: 600,000 * 0.04 = 24,000.

Next, we calculate the probability of 18 or more vegans showing up out of 24,000 by using a binomial distribution with n = 350 (the number of people expected on opening night) and p = 0.04 (the probability of a person being vegan). We then sum the probabilities for 18, 19, 20, ..., 350 vegans.

Using a calculator or statistical software, we find that the approximate probability is 0.9488, or 94.88%.

Answer:

62.5

Step-by-step explanation:

By dividing 50 by 10 and 10 by 2 we can find that r, or the common ratio is 1/5, meaning that this series converges, so it is solvable. The formula for a convergent series is [tex]\frac{a_{1}}{1-r}[/tex]. By plugging in 1/5 for r and 50 for  [tex]a_{1}[/tex] we can find that the sum of this infinite series is 62.5

Answer:

Remainder is 691.

Step-by-step explanation:

Given function is [tex]10x^4-6x^3+5x^2-x+1[/tex].

Now we need to find remainder if we divide given function [tex]10x^4-6x^3+5x^2-x+1[/tex] by (x-3)

(x-3) means plug x=3 into [tex]10x^4-6x^3+5x^2-x+1[/tex] to find remainder.

[tex]10x^4-6x^3+5x^2-x+1[/tex]

[tex]=10(3)^4-6(3)^3+5(3)^2-(3)+1[/tex]

[tex]=10(81)-6(27)+5(9)-(3)+1[/tex]

[tex]=810-162+45-3+1[/tex]

[tex]=856-162-3[/tex]

[tex]=856-165[/tex]

[tex]=691[/tex]

Hence remainder is 691.

Answer:

The remainder = 691

Step-by-step explanation:

Let p(x) = 10x⁴ - 6x³ + 5x² - x + 1

We have to divide p(x) by (x - 3)

To find the remainder we  have to find p(3)

To find the remainder

p(x) = 10x⁴ - 6x³ + 5x² - x + 1

p(3) = 10 * (3)⁴ - 6*(3)³ + 5* (3)² - 3 + 1

 = (10 * 81 ) - ( 6 * 27 ) + (5 * 9) - 3 + 1

 = 810 - 162 + 45 - 3 + 1 = 691

Therefore the remainder is 691

Answer: The rate is 7.5%.

Step-by-step explanation: The formula to calculate simple interest is:

Interest = Principal x Rate x Time

So, we need to plug our information into the formula:

$562.50 = $1,500 x R x 5

Now, perform the multiplication that you can:

$562.50 - $7,500R

Next, divide both sides by $7,500:

.075 = R

Therefore, the rate is 7.5%.

Answer:

  8

Step-by-step explanation:

If each portion is 1/8 of the cake, there are 8 equal-size portions. That is what the denominator of the fraction means.

Sadie can cut the rectangular cake into 8 portions if each portion is 1/8 of the whole cake.

To determine how many portions Sadie can cut the rectangular cake into if each portion is 1/8, we need to understand that she is essentially dividing the cake into 8 equal parts.

Here's a step-by-step explanation:

Whole Cake: The entire rectangular cake represents one whole (1).

→ Portion Size: Each portion is 1/8 of the whole cake.

→ Calculation: We divide 1 by 1/8. Mathematically, this is the same as multiplying by the reciprocal,

so 1 ÷ (1/8) = 1 × 8

                 = 8.

Therefore, Sadie can cut the rectangular cake into 8 portions of size 1/8 each.

1/2 is .5

and knowing this, just make a fraction out of the numbers before .5 .

2/5 is .4

Answer:

∠BAM=30°

Step-by-step explanation:

Points A and B split the circle into two arcs. If the measure of minor arc AB is 150°, then the measure of the major arc AB is 360°-150°=210°.

If point M splits major arc with the ratio 2:5, then

Angles BOM and AOM together form angle with the measure 210°, thus

2x+5x=210,

7x=210,

x=30°

and ∠BOM=60°, ∠AOM=150°.

Consider isosceles triangle BOM. In this triangle,

∠OBM=1/2(180°-60°)=60°.

Consider isosceles triangle AOB. In this triangle,

∠OAB=1/2(180°-150°)=15°.

Consider isosceles triangle AOM. In this triangle,

∠OAM=1/2(180°-150°)=15°.

Thus, ∠BAM=15°+15°=30°

Answer:

arc BAM =  300°

Step-by-step explanation:

Refer to the figure attached.

arc AB = 150°

then:

arc AMB = 360° - 150° = 210°

arc AMB can be decomposed as:  

arc AM + arc MB = arc AMB (eq. 1)

From data:

arc MB/arc AM = 2/5

arc MB*(5/2) = arc AM (eq. 2)

Replacing equation 2 into equation 1:

arc MB*(5/2) + arc MB = 210°

arc MB*(7/2) =  210°

arc MB = (2/7)*210° = 60°

On the other hand:

arc MB + arc BAM = 360°

arc BAM = 360° - 60° =  300°

Answer: The answers are 2.54x and 30.48 cm.

Answer:

Option b

Step-by-step explanation:

To solve this problem we must test if the function is even.

If f(-x) = f(x) then the function is even and is symmetric with respect to the y-axis.

If f(-x) = -f(x) then the function is odd and has symmetry with respect to the origin.

We have the function:

[tex]f(x) = \frac{e^x + e^{-x}}{2}[/tex]

We make:

[tex]f(-x) = \frac{e^{-x} + e^{-(-x)}}{2}[/tex]

Rewriting the function we have

[tex]f(-x) = \frac{e^{-x} + e^{x}}{2} = \frac{e^{x} + e^{-x}}{2}\\\\f(-x) = f(x)[/tex]

Finally, the function has symmetry with respect to the y axis.

ANSWER

The number is 18.

EXPLANATION

Let the number be x.

When this number is divided by 3, we obtain the quotient,

[tex] \frac{x}{3} [/tex]

When 5 is subtracted from this quotient, we get,

[tex] \frac{x}{3} - 5[/tex]

If the result is 1, then we have;

[tex] \frac{x}{3} - 5 = 1[/tex]

We group similar terms to get,

[tex] \frac{x}{3} = 1 + 5[/tex]

This gives us,

[tex] \frac{x}{3} = 6[/tex]

Multiply both sides by 3.

[tex]x = 6 \times 3[/tex]

[tex]x = 18[/tex]

Therefore the number is 18.

Answer:

The ratio for sin(X) is [tex]\frac{\sqrt{119} }{12}[/tex]

The ratio for cos(X) is [tex]\frac{5}{12}[/tex]

Step-by-step explanation:

- The ratio of the sine of a right triangle is:

[tex]sin(\alpha)=\frac{opposite-side}{hypotenuse}[/tex]

Since we need the ratio for angle X, [tex]\alpha =X[/tex]. From the picture we can infer that the opposite side of X is [tex]\sqrt{119}[/tex]. The hypotenuse (the side opposite to the right angle) is 12, so replacing the values:

[tex]sin(X)=\frac{\sqrt{119} }{12}[/tex]

- The ratio of the cosine is:

[tex]cos(\alpha)=\frac{adjacent-side}{hypotenuse}[/tex]

Similarly, [tex]\alpha =X[/tex], adjacent side = 5, and hypotenuse = 12, so

[tex]cos(X)=\frac{5}{12}[/tex]

Answer:

Sin X =√119/12

Cs X = 5/12

Step-by-step explanation:

It is given a right angled triangle.

Points to remember

Sin θ = Opposite side/Hypotenuse

Cos θ = Adjacent side/Hypotenuse

To find the value of Sin X  

Here X is an angle

Opposite side = √119

Hypotenuse = 12

Sin X = Opposite side/Hypotenuse = ZY/XY = √119/12

To find the value of Cos X

Adjacent side of X = 5

Cos X = Adjacent side/Hypotenuse = XZ/XY = 5/12

Answer:

651 and 3/25 is 651.12 as a mixed number.

Answer:

multiply the radius by 2π

Step-by-step explanation:

The formulas for circumference of a circle is

C = πD     where D is the diameter,

or

C = 2πr    where r is the radius.

Either formula is correct, but we will work with the second one since the question is asking about radius.

We see that 2π(r) = the circumference, so multiply r by 2π to get the circumference

Hello there! How are you doing? I am doing fine! I'll answer the question now.  

So basically when wanting to find the circumference of a circle you simply use the formula, C = 2 times PI times R. PI is the infamous number known for 3.1415912654... and the R represents the radius. You would multiply 2 times PI  and then after getting that you would basically multiply it by the radius. And then that would be the circumference and be the answer to any problem you face like this. Know that diameter is 2 times the radius and that all.

Hope this helped! Your welcome! I can help with other history stuff too! And byee! :)

Final answer:

The factory takes 18 hours to produce 180 cars.

Explanation:

To find out how many hours the factory takes to produce 180 cars, we need to set up a proportion. Since the factory takes 6 hours to produce 60 cars, we can set up the proportion:

6 hours / 60 cars = x hours / 180 cars

Cross-multiplying, we get:

6(180) = 60(x)

Simplifying, we have:

1080 = 60x

Dividing both sides by 60, we find:

x = 18

So, the factory takes 18 hours to produce 180 cars.

Answer:

Each base is 40

Step-by-step explanation:

An isosceles triangle has a total of 180. An isosceles has two sides that are the same and one different. Think of “sos” in the word isosceles to help. If one is 100, then you have 80 left. 80 divided by 2 is 40.

Area = 1/2(diagonal) * √4*side^2 - diagonal^2

Area = 1/2(16)*√(4*17^2 - 16^2)

Area = 8 * √(4*289-256)

Area = 8 *√900

Area = 8 * 30

Area = 240 m^2
