Answer: Many utility companies promote energy conservation by offering discount rates to ... who keep their energy usage below certain established subsidy standards. A recent EPA report notes that 70% of the island residents of Puerto Rico have reduced their electricity usage sufficiently to qualify for discounted rates.

Answer:
b=7
Step-by-step explanation:
Plug 3 into a since a=3.
2(3)+b=13
Then solve for 2(3)
6+b=13
Now isolate the b, so move the 6 to the other side. (Basically subtract 6 from both sides)
b=13-6
b=7
Answer:
41
Step-by-step explanation:
H = x, L = 1.5 x;
L + W + H = 6
x + 1.5 x + W = 6
W = 6 - 2.5 x
Dimensions of the camera in terms of x:
x, 1.5 x, 6 - 2.5 x.
V = L x W x H
V = x * 1.5 x * ( 6 - 2.5 x ) = 9 x² - 3.75 x³
V ` = 18 x - 11.25 x² ( V max is when V` = 0 )
18 x - 11.25 x² = 0
x ( 18 - 11.25 x ) = 0
11.25 x = 18
x = 18 : 11.25
x = 1.6
The dimensions are:
L = 2.4
W = 2.0
H = 1.6
