Answer:
Step-by-step explanation:
g(h(x))=g(3x + 7). Since h(x)=3x + 7
g(h(x))= 2(3x + 7) - 5
g(h(x))= 6x + 14 -5
=6x +9
Answer:
$11.60
Step-by-step explanation:
4x = 46.4
x = 11.6
The candle has the shape of a cylinder with height H=6 in, and radius of the circular base R= (2.8)/2 =1.4 (in).
The volume of the cylinder is Area(base)*height =

(in cubed)
According to Cavalieri's principle, the volume of the candle is equal to the volume of the cylinder we described.
Answer: 37 in cubed
Answer:
If width = 60 m, length = 195 m.
If width = 150 m, length = 465 m.
Step-by-step explanation:
The area of a rectangle is l * w or length times width.
So we can set an equation (letting w = width and x = length)
w = 
Part 1: width = 60m:
60 = 
65 = 
x = 195 m
Part 2: width = 150 m:
150 = 
155 = 
x = 465 m
Answer:
Difference between high and low temperatures: 12°F
Average change in temperature per hour: 2°F
Step-by-step explanation:
The difference between high and low temperatures was: 7 - (-5) = 12 (°F)
Midnight is 12am, so 6pm to midnight is 6 hours.
The average change in temperature per hour is: 12 / 6 = 2 (°F)
