Answer:
The height of the roof is 534.8 feet.
Step-by-step explanation:
Let h be the height of the roof.
We know the formula

Since, the stone is dropped from the edge of the roof hence, the initial velocity should be zero. Thus, u = 0

Now, we have
v = -185 feet per second
g = 32 feet per square second
On substituting these values, we get

The height of the roof is 534.8 feet.
The prime number is 53 because the others have factors other than itself and 1 but 53 doesn't
Answer:
2(u+3v)
2 times u is 2u and then 2 times 3v is 6v.
2u+6v
Carmel would need 7 gas tanks. (2,240 ÷ 320 = 7)
Carmel would need $273 because since she needs $39 dollars for one gas tank, you would have to multiply that by 7. (39 x 7 = $273)
