According to her running log, Shivani averaged 3.2 miles per week last month and 2.8 miles per week this month. By what percent has her average decreased?
To find the percent decrease in Shivani's average, we need to calculate the decrease in miles per week and then express it as a percentage of the original average.
The decrease in average miles per week is 3.2 - 2.8 = <<3.2-2.8=0.4>>0.4 miles per week.
To express this decrease as a percentage of the original average, we divide the decrease by the original average and multiply by 100: (0.4/3.2) * 100% = 12.5%.
Therefore, Shivani's average has decreased by 12.5%.
The cheerleading squad at Morristown High School had 10 members with the old coach. Now, with the new coach, there are 10% fewer members on the squad. How many members are on the squad now?
If there were 10 members on the squad with the old coach, and the new coach decreased the squad size by 10%, then 10% of 10 members is (10/100) * 10 = <<(10/100)*10=1>>1 member.
Therefore, there are 10 - 1 = <<10-1=9>>9 members on the squad now.
9?
Apologies for the incorrect response.
If there were 10 members on the squad with the old coach and there is now 10% fewer members, we need to calculate 10% of 10 and subtract it from 10.
10% of 10 is (10/100) * 10 = 1.
Therefore, there are 10 - 1 = 9 members on the squad now.
A few weeks ago, Samuel bought 5 apples from his local farmers' market. Today, the number of apples Samuel bought was 40% lower. How many apples did he buy today?
If Samuel bought 5 apples a few weeks ago, and today he bought 40% fewer apples, we need to calculate 40% of 5 apples.
40% of 5 apples is (40/100) * 5 = 2 apples.
Therefore, Samuel bought 5 - 2 = 3 apples today.
