Answer:
Total number of jumping Jacks by Linda in 7 days = 825
Step-by-step explanation:
Total number of days Linda jumped = 7 days
Now, for first 3 days, jumping jacks each day = 75
So, total jumping jacks in first 3 days = 75 x 3 = 225
Now, number of days left in the week = 7 days - 3 days = 4 days
Also, for next 4 days, jumping jacks each day = 2 x 75 = 150
So, total jumping jacks in last 4 days = 150 x 4 = 600
Hence, the Total number of jumping Jacks in 7 day
= Jumping Jacks in fist 3 days + Number of jumping jack in last 4 days
= 225 + 600
= 825
Hence, Total number of jumping Jacks by Linda in 7 days = 825

x = 2.5
The three rugs will cover an area of 108π square feet.
Step-by-step explanation:
Given,
Radius of each rug = 6 feet
Number of rugs bought = 3
As the rugs are circular;
Area covered by each rug = πr²
Area covered by each rug =
Area covered by each rug =
Area covered by each rug = 36π square feet
Area covered by 3 rugs = 36π*3 = 108π square feet
The three rugs will cover an area of 108π square feet.
