In the first week
1 answer:
The percent change in the number of people who went to the pool
between the first and last week is 10% less
Step-by-step explanation:
The given is:
- In the first week of July, a record 1,060 people went to the local swimming pool
- In the second week, 105 fewer people went to the pool
- In the third week, 135 more people went to the pool than in the second week
- In the fourth week, 136 fewer people went to the pool than in the third week
We need to find the percent change in the number of people who
went to the pool between the first and last weeks
∵ There were 1060 people in the 1st week
∵ There were 105 fewer people in the 2nd week
∴ The number of people in the 2nd week = 1060 - 105 = 955
∴ There were 955 people in the 2nd week
∵ There were 135 more people in the 3rd week than the 2nd week
∵ There were 955 people in the 2nd week
∴ The number of people in the 3rd week = 955 + 135 = 1090
∴ There were 1090 people in the 3rd week
∵ There were 136 fewer people in the 4th week than in the 3rd week
∵ There were 1090 people in the 3rd week
∴ The number of people in the 4th week = 1090 - 136 = 954
∴ There were 954 people in the 4th week
Let us find the change from 1st week to last week
∵ There were 1060 people in the 1 st week
∵ There were 954 people in the last week
∴ The change = 1060 - 954 = 106
∵ Percent change = × 100%
∴ Percent change = × 100%
∴ Percent change = 10%
The percent change in the number of people who went to the pool
between the first and last week is 10% less

The area of the given diagram is 29.817 square centimeters. The given diagram is combination of rectangle and semi circle.
Step-by-step explanation:
The given is,
Given diagram is combination of Rectangle and Semi circle.
Step:1
Res the attachment,
Area of given diagram = Area of A + Area of B..............(1)
Step:2
For A,
The A section in the given diagram is semi circle,
Diameter of semi circle = Total distance - ( 2+3)
( ∵ 2, 3 are top distance in the given diagram)
Diameter, d = 5 cm
Radius,
r = 2.5 cm
Area, ........................(2)
Step:3
For B,
Area of rectangle is,
.....................(3)
Where, l - Length = 10 cm
b - Width = 2 cm
Equation (3) become,
Area of B, = 20
Step:4
From the equation (1),
Area of given diagram = 20+ 9.81747
Area = 29.817 square centimeters
Result:
The area of the given diagram is 29.817 square centimeters. The given diagram is combination of rectangle and semi circle.
