Answer:
E. 800%
Step-by-step explanation:
Since,
u = 8d/h² __________ eqn (1)
Now, density (d) is doubled and usage (h) is halved.
Hence the new life (u'), becomes:
u' = 8(2d)/(0.5h)²
u' = 8(8d/h²)
using eqn (1), we get:
u' = 8u
In percentage,
u' = 800% of u
In words, the percentage increase in useful life of the equipment is <u>800%</u>.
Answer:
The length of the hypotenuse is 5 inches.
Step-by-step explanation:
The formula for finding the hypotenuse is ,
with a and be being the two shorter sides of the triangle, while c is the hypotenuse.
Let's plug in our values for a and b and solve.
16 + 9 =
25 =
What is the square root of 25? 5.
The length of the hypotenuse is 5 inches.
