A sheet of paper has a perimeter of 39 in. if the width of the paper is 8.5 in . what is the length of the sheet of paper

Valentin [98]

If the perimeter is 39 what you have to do is 39 - 8.5 - 8.5 that will give you 22 and divide 22/2 and that gives you 11. So 11 is the length

Blake rows his boat against a current 90 yards in 15 minutes. With a current, he rows 90 yards in 9 minutes. What is the rate at

Anna71 [15]

Answer:

90 yards in 15 minutes =6 yds/min

90 yards in 9 minutes =10 yds/min

x = current rate

r = rowing rate

r + x = 10

r - x = 6 Adding both equations

2 r = 16

rowing rate = 8 yds/min

x = 2 yds/min (current rate)

Determine the volume of the rectangular prism.<br>

Flauer [41]

Answer:

Step-by-step explanation:

We know the formula for a rectangular prism is length × width × height

We also know all the sides so we can rewrite the formula replacing variables.

The length is 8, the width is 2 $\frac{1}{2}$ and the height is 2 $\frac{1}{2}$

8 × 2 $\frac{1}{2}$ × 2 $\frac{1}{2}$

Multiply which ever way is easy for you. I am just multiplying from left to right.

8 × 2 $\frac{1}{2}$ = 20

20 × 2 $\frac{1}{2}$ = 50

Now we get 50. Before we put our answer as 50, there are two more steps.

First we need to add the measurement unit which is feet or ft

We also need to add ³ since it is volume

<u>50 ft³ is our final answer</u>

dedylja [7]

I think the answer is $2.01 per 1ft of redwood and pine

282/2
=141

$141/70ft ÷ 70/70
=$20.1 per 1ft

Solve y + -7 = 13 ?

ratelena [41]

Well first off if you have a negative sign in front of the seven, DO NOT have a plus sign because it will be confusing. So y-7=13? , You add 7 to 13 and = 20, so y= 20
