Question

On the first day of​ June, there were about 15.01 h of daylight in a city. Five months​ later, there were about 9.60 h of daylight. What was the percent​ decrease?

Answer 1

36.04 % decrease

Step-by-step explanation:

given initial daylight hours: 15.01 hrs

final daylight hours(5 months later) : 9.60 hrs

change in daylight hours = final - initial = 9.6 - 15.01 = -5.41

(or 5.41 hour decrease)

percentage decrease = (change in daylight hours / initial daylight hours) x 100%

= (5.41 / 15.01) x 100%

= 36.04 % decrease

Answer 2

From June to five months later, there is a 36.04% decrease in daylight hours. This is calculated by finding the difference in daylight hours and dividing by the original amount, then converting the result to a percentage.

Step-by-step explanation:

To find the percent decrease in the amount of daylight from June to five months later, you first need to find the difference in the amount of daylight between these two points.

The difference is calculated by subtracting the lesser amount (9.60 h) from the greater amount (15.01 h):

15.01 h - 9.60 h = 5.41 h

Next, to calculate the percent decrease, you divide the difference by the original amount (the amount in June 15.01 h), and then multiply by 100 to get the percentage:

(5.41 h / 15.01 h) x 100 = 36.04%

Therefore, there was a 36.04% decrease in daylight hours from June to five months later.
