Answer:
B.)8ft
Step-by-step explanation:
Set up a proportional to the roof slope:
2/5 = x/20
Cross multiply:
40/5 = 5x/5
x=8ft
226,000
Step-by-step explanation:
250,000-24,000=226,000
Answer:
v = 120
Step-by-step explanation:
If v is inversely proportional to square root of d, then we can write
= k
If v = 30 and d = 400, then
30(
) = k
k = 30(20) = 600
Now
= 600
If d = 25, then v
= 600
5v = 600
v = 120
Answer:
The answer is B. No solution
Step-by-step explanation:
16x^2 is not equal to 100, so the equation is false, and there is no solution for x.
