Answer:

Therefore ,(D)  360π inches.

Step-by-step explanation:

Given: A tire at the top of a hill starts rolling down the hill. If the diameter of the tire is 36 inches.

To find: How many inches has the tire rolled if it has rotated exactly 10 times down the hill.

Solution : We have given that diameter of tire = 36 inches.

 Radius = \frac{Diameter}{2}

  Radius = \frac{36}{2}

 Radius = 18 inches.

Circumference of tire = 2 * π radius

Circumference of tire = 2 *  π 18

                                    = 36π

We need to  rolled the tire 10 times down the hill

then,  10 * 36π = 360π inches.

Therefore ,(D)  360π inches.

MissTica

let the number of sides be n.

Thus,

(n-2)x180=330

n-2=1.83

n=3.83

Rounding off we have, n=4.

Thus the total number of side is 4.

Kay and Allen sell cell phones. Kay sold 17 more cell phones than Allen. Together they sold 117. How many did they sell individu
denis-greek [22]

Answer:

Kay sold 67 cell phones and Allen sold 50 cell phones.

Step-by-step explanation:

Let k = # cell phones Kay sold and a = # cell phones Allen sold.

k + a = 117

k = 17 + a

So:

(17 + a) + a = 117

2a = 100

a = 50

Plug this back into 2nd equation:

k = 17 + a

k = 17 + 50

k = 67

Kay sold 67 cell phones and Allen sold 50 cell phones.

An online video streaming service offers two plans for unlimited streaming. Plan A has a one-time $25 membership fee and is $8 p
Zanzabum

Answer:

The answer is that both plans are equal.

Step-by-step explanation:

you start by putting the plans into an equation then you set them equal to each other. you need to assign a variable for the number of months. we'll call it M. It would look like this:

plan A - 25 + 8M

plan B - 5 + 12M

25 + 8M = 5 + 12M

Then you solve which looks like this:

25 + 8M = 5 + 12M

     -8M            -8M

25 = 5 + 4M

-5    -5

20 = 4M

/4       /4

5 = M

Now we aren't done after finding out what M equals. We still need to know what each plan will cost. So, we substitute what M equals into the equation. if they both end up equaling the same thing then its equal. if you get two different numbers they aren't. it would look like this:

25 + 8(5) = 5 + 12(5)

25 + 40 =  5 + 60

65 = 65

They are equal. Both plans will cost 65 dollars.
