Answer:
B
Step-by-step explanation:
The wording in the problem statement is ...
... "less than 3 years"
... "at least 3. but less than 6 years"
so we expect the inequality symbols to look like ...
... 0 ≤ x < 3
... 3 ≤ x < 6
These match <em>the second piecewise function</em>.
If we want to calculate the time it takes to fill a water tank, we need the flow and volume of the tank.
The flow must be a data, but for the volume of the tank we need mathematics.
For example, if it is a cylinder, we need mathematics to know that the volume of the cylinder is:
V = pi * r ^ 2 * h
Difference between 60 and 45 is 15 so $15 in 10 cent would be 150 so 150 miles . Answer: you would need to drive more than 150 miles for plan b to save money:)
Answer:
D) 57
Step-by-step explanation:
1/3x- 1/2 = 18 1/2
1/3x = 19
(3) * 1/3x = 19 (3)
x = 57
