Studentka2010 [4]
Statement 3 is QR=RT. This can be validified by the reason of Transitive Property of Equality. This property is applied when the situation is if a=c and b=c, then a=b. The same is true for QR=59 and RT=59, then QR=RT.

Given the following formula, solve for I.<br><br> P = 2(1 + 6)<br><br> PLEASE HELP!!!
Pepsi [2]

Step-by-step explanation

Here ...I'm not too sure about the question as you have written

P = 2 ( 1 + 6 ) and ask to solve for L ...

.So I guess the question you have written is wrong .. ...and I guess there should be L in the place of 1.

...So let me correct the question....

P = 2 ( l + 6 )

P = 2l + 12

P - 2l = 12

- 2l = 12 - P

- 2l = - P + 12

Change the sign of both side of the equation...

2l = P + 12

divide both side by the same number...

L = ( P + 12 ) ÷ 2

l =  \frac{1}{2} p - 12 \times  \frac{1}{2}  \\

Calculate the product of rational numbers...

l =  \frac{1}{2} p - 6 \\

Virginia Beach is 10 miles wide and 30 miles long. If one inch of rain falls on Virginia Beach, how many cubic feet of rain fell
Arte-miy333 [17]

1 mile = 5280 feet.

Convert the dimensions to feet:

10 miles = 5280 x 10 = 52,800 feet

30 miles = 5280 x 30 = 158,400 feet

Multiply together to get the area:

52,800 x 158,400 = 8,363,520,000 square feet.

1 inch = 1/12 of a foot.

Multiply the area by 1/12 for the volume of rain:

8,363,520,000 x 1/12 = 696,960,000 cubic feet.
