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:
As the above angles are corresponding, so they must be equal.
So, 17x - 4 = 12 + 5x
17x - 5x = 12 + 4
12x = 16
x = 16/12
x = 4/3.
Answer:
D. y=2.50x
Step-by-step explanation:
Since the equation asks for the total cost of a vase of flowers (y) that goes on the left side. Each flower costs 2.50 and the flower shop depends on the number of flowers ordered, which makes it a variable. Therefore C is wrong because it has 2.50 as a constant.
The ending equation will be y = 2.50x
Written in context this means that the total cost of a vase of flowers is equal to the cost of each flower (2.50) by how many flowers are ordered.

EXPLANATION: Simply substitute the value of 3 given. In other words, f(3) is the function of f(x), however, in this case, x is 3
f(3)=3(3)−4
Distribute 3 through the parenthesis
f(3)=9−4
Simplifyf(3)=5
Step-by-step explanation:
It’s literally 6x2x5 (60 sq ft)
