YOUR ANSWER IS B
Step-by-step explanation:
Answer:
f(g(5)) = 16.5
Step-by-step explanation:
To calculate f(g(5)), evaluate g(5) then substitute the value obtained into f(x)
g(5) = 
× 5 = 2.5 , then
f(2.5) = 5(2.5) + 4 = 12.5 + 4 = 16.5

Step-by-step explanation:
the first option is the answer
Step-by-step explanation:
4c + 6a <= 120 [building hours]
4c + 4a <= 100 [testing hours]
4 * 20 + 6 * 6 <= 120
80 + 36 <= 120
116 <= 120
true, they have enough building hours
4 * 20 + 4 * 6 <= 100
80 + 24 <= 100
104 <= 100
false, they won't have enough testing hours
the first option is the answer
Write and solve an equation of ratios, as follows:
32 fl oz 60 min
----------- = ------------
x 135 min
Then 60x = (32)(135) = 4320, and x = 72 oz.
damron should drink 72 fl. oz. of water if he rides 135 min.
