Question

Lenny is doing an experiment for his science class. He has a glass bucket filled with 27 centimeters of water. Each week he measures the height of the water to see the effects of evaporation. If the height decreases 4 centimeters each week, which equation represents the height (h) of the water after a given number of weeks (w)?

A. (h = 27 - 4w)

B. (h = 27 + 4w)

C. (h = 4w - 27)

D. (h = 27 times 4^w)

Answer 1

The equation (h = 27 - 4w) represents the height of the water after a given number of weeks.

Step-by-step explanation:

The equation that represents the height (h) of the water after a given number of weeks (w) is A. (h = 27 - 4w).

To understand this, we can break it down step by step.

1. Start with the initial height of the water, which is 27 centimeters.
2. After each week, the height decreases by 4 centimeters.
3. So, for each week, we subtract 4 times the number of weeks (4w) from the initial height (27) to get the height after a given number of weeks (h).
