The answer is 120 sections.

Here's an explanation:

The rope is 105 feet long, and each section needs to be 7/8 feet. So to find the number of sections, you need to divide 105 by 7/8. 105 divided by 7/8 gives you the quotient 120. So there are 120 sections.

Hey can some one help me with this

Leno4ka [110]

Hello!

First you have to find the surface area of what he is painting

Finding the areas of all the rectangles he is painting

14 * 8 = 112
14 * 8 = 112
12 * 8 = 96
12 * 8 = 96
12 * 14 = 168

Add all these up

112 + 112 + 96 + 96 + 168 = 584

Divide this by the amount of area a pint of paint covers

584 / 90 = 6.4888...

He needs 7 pints of paint because he needs more than 6

Multiply this by the cost of 1 pint of pint

7 * 7.98 = 55.86

The answer is $55.86

Hope this helps!

A website charges $0.99 to download a game and a $12.49 membership fee. Write an equation that gives the total cost in dollars (

nata0808 [166]

C = Cost To Download
M = Membership Fee.
T = 0.99C + M

Now, Plug In 6 For C.
And 12.49 For M
T = 0.99 * 6 + 12.49

0.99*6 = 5.94

T = 5.94 + 12.49

5.94+12.49 = 18.43

T = 18.43.

So, If You Want To Buy 6 Games On The Website, It Will Cost $18.43
