The cost of donuts in Dunkin Donuts is directly proportional to the number of donuts purchased. Justin paid $5.04 for 7 donuts. If c represents the cost, in dollars, and d represents the number of donuts purchased, which equation best represents this relationship?

Answer:

189

Step-by-step explanation:

Answer:

[tex] 4 + 7(3 \times 9) + 967 \\ = 4 + 7(27) + 967 \\ = 4 + 189 + 967 \\ = 193 + 967 \\ = 1160[/tex]

=> None of the options match the correct answer.

Answer:

5

Step-by-step explanation:

use the pythagorean theorem

[tex] {h}^{2} = {p}^{2} + {b}^{2} [/tex]

[tex] {h}^{2} = {(4)}^{2} + {(3)}^{2} [/tex]

[tex] {h}^{2} = 16 + 9[/tex]

[tex] {h}^{2} = \sqrt{25} [/tex]

[tex] {h}^{2} = \sqrt{25} = 5[/tex]

Answer:

the volume for the second page is 607.5

Step-by-step explanation:

Answer:

40 and 202.5 m³

Step-by-step explanation:

(7)

Since the figures are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{PQ}{16}[/tex] = [tex]\frac{30}{12}[/tex] ( cross- multiply )

12 PQ = 480 ( divide both sides by 12 )

PQ = 40 in

-------------------------------------------------------------------

The volume (V) of a pyramid is calculated as

V = [tex]\frac{1}{3}[/tex] Ah ( A is the area of the base and h the height ) , then

V = [tex]\frac{1}{3}[/tex] × 9² × 7.5

   = [tex]\frac{1}{3}[/tex] × 81 × 7.5

   = 27 × 7.5

   = 202.5 m³

Answer:

XUY = 40 degrees

WUZ = 90 degrees

XUZ = 50 degrees

VUW = 40 degrees

VUY = 140 degrees

I hope this helps :)

Step-by-step explanation:

WUZ is a right angle, so 90 degrees. YUW is a straight angle, so it is 180 degrees, so WUZ + XUZ + XUY = 180, WUZ is 90 and XUY is 40, so 90 + 40 = 130, 180 - 130 = 50

XUZ is 50 degrees

Since VUW is on the opposite side of XUY, it is the same degrees as it, so VUW is 40 degrees

YUW is 180 degrees, so VUW + VUY = 180, VUW is 40 degrees, so VUY is 180 - 40 = 1400, VUY is 140 degrees

Now we have them all:

XUY = 40 degrees

ZUW = 90 degrees

XUZ = 50 degrees

VUW = 40 degrees

and finally,

VUY = 140 degrees

Reading this whole thing, it sounds sooo weird

Answer:

Step 1 - Subtract 12 from both sides of the equation.

Step 2 - Simplify.

Step 3 - Subtract 10x from both sides of the equation.+

Step 4 - Simplify

Step 5 - Divide both sides of the equation by the same term.

Step 6 - Simplify

All this would equal to,

x = 4

Hope you have a great day!

Step-by-step explanation:

X was already negative so the only thing turning negative is Y!

So the first one is correct.

They all say the same thing

X ya era negativo, por lo que lo único que se vuelve negativo es Y!

Entonces el primero es correcto

X était déjà négatif donc la seule chose qui devient négative est Y!

Donc le premier est correct

X已经是负数，所以唯一变成负数的就是Y！

所以第一个是正确的

X已經是負數，所以唯一變成負數的就是Y！

所以第一個是正確的

Step-by-step explanation:

There are supposed to be 180 degrees in every triangle.

Therefore, no triangles exist.

Step-by-step explanation:

circumference = 452.16 cm^2

here's your solution

=> Radius = 12 cm

=> circumference of circle = πr^2

=> circumference = 3.14*12*12

==> circumference = 452.16 cm^2

Answer:

Class A

Step-by-step explanation:

If you look a class a, you see that the box in the boxplot is in between 76 and 88, and that space shows 50% of the class

Answer: M{x°}=89

A triangle has 3 sides, and the total degree is 180°. So make a equation to find the third degree (x).

Answer:

12a. 22.5%

12b. 77.5%

13. $4000

Step-by-step explanation:

12.

    a. 315/1400= 0.225 = 22.5%

    b. 1400-315=1085  1885/1400= 0.775 = 77.5%

13.

[tex]\frac{5}{100} = \frac{200}{4000}[/tex]

5/100 will be equal to 200/4000 so the hair stylist made $4000 in sales.

also if im wrong sorry!!

Answer:

Step-by-step explanation:

If we multiply both sides by x, we get y = 4x, which is direct variation:

Answer:

A, B, and D.

Step-by-step explanation:

A. represents the Holy Trinity. Christians have the belief that the whole universe was created by God.

B. represents the 3rd day after Jesus died, but then he rose. This is the day that Christian's celebrate as Easter.

D. represents the deliverance from sin and its consequences, believed by Christians to be brought about by faith in Christ.

Answer:

51

Step-by-step explanation:

26+(3x+1)= 180

Answer:

So the answer is 13 classes member and 9 non member

Step-by-step explanation:

so you gotta do 24 + 3x = 7y ok?

and x equals 13 so 39 + 24 = 63

and non member is 7x = 63

x = 9

Hope I helped :D

Answer:

Explained below

Step-by-step explanation:

a = Amy

s = sister

s x 5 = a

Plug in the numbers:

2 x 5 = 10

4 x 5 = 20

6 x 5 = 30

8 x 5 = 40

As you can see, Amy's pay is shown as 5 times more than her sister's.

Hope this helps! :)

Answer:

Equation: "5x" or "5x + 0"

Step-by-step explanation:

This is a linear function since the change in x and y values is constant. Let "Amy's pay in dollars" be represented by x, and "Sister's pay in dollars" be represented by y. Since x value is going up by +10 every time, that will be our numerator, and since y value is going up by +2 every time, that would be the denominator, according to the slope equation: [tex]\frac{x}{y}[/tex]. Thus it would give the equation as [tex]\frac{10}{2}[/tex], if simplified, our slope will be 5/1 also can be written as 5. Now to find the y-intercept we have to see the y value where x value is 0. To get x = 0 you have to imagine the table given going backwards. Meaning just as how to move to the right of the table by adding 10 to the x-value and 2 to the y-value, you would have to subtract 10 from the x-value and subtract 2 form the y value. Keep doing this until you have 0 for x-value and notice the y-value would be 0. Hence, the y-intercept for this equation would be 0.

Hope this helps, Good Luck!
