Question

An ice sculpture is melting because of heat. Assuming its height changes by -5/32 meters every hour, what will be the change in height after 4 hours?

a) -10 meters

b) -20 meters

c) -5/8 meters

d) -40 meters

Answer 1

The height of the ice sculpture decreases by -5/32 meters each hour, and after 4 hours, the total change in height is -5/8 meters. Thus, the correct answer to the question is c) -5/8 meters.

Step-by-step explanation:

The question asks about the change in height of an ice sculpture due to melting over time. Knowing that the sculpture's height decreases by -5/32 meters every hour, we can calculate the total change after 4 hours by multiplying the hourly change by the number of hours.

To find the change in height after 4 hours, we perform the following calculation:

(-5/32 meters/hour) × 4 hours = -20/32 meters

Simplifying the fraction -20/32, we get:

-20/32 = -5/8 meters

Therefore, the correct answer is c) -5/8 meters, which represents the total change in height of the ice sculpture after 4 hours.
