Answer 1

r=t/d

Answer 2

One the first question, you need to isolate the "t" to both sides. Solve that and you getd/t=r or for your answer choices, r=t/d

Answer 3

Alright thanks! Is my second answer correct though?

Answer 4

We're find the width, formula would be, A=L*W. Plug in the numbers to the letters taht they belong to.

Answer 5

A = L * 90?

Answer 6

Atually, wait. Let me review what I did lol.

Answer 7

Okay xd

Answer 8

Here we go, the formula for this problem is: P=2(L+W).

We don't quite know what's 'W' correct? So to get that we need to plug in the numbers into the letters that they belong to.

P=2(L+W)

90=2(15)

90=30

W=30

Answer 9

Ah okay, thanks for your help!

Answer 10

No problem!
