Answer:
25%
Step-by-step explanation:
The number of people who went to the local swimming pool in the;
first week = 1120
second week ( 105 fewer people) = 1120 - 105 = 1015
third week (135 more people) = 1015 + 135 = 1150
fourth week (310 fewer people|) = 1150 - 310 = 840
The percent decrease in the number of people who went to the pool over these four weeks
= (1120 - 840)/1120 * 100%
= 280/1120 * 100%
= 1/4 * 100%
= 25%
It means that the number of people who went to the local swimming pool over the 4 weeks decreased by 25%
Answer:
1 1/8 inches.
Step-by-step explanation:
As the sails are similar, corresponding sides are in the same ratio, so we have the equation
:24/3 = 9/b where b = base of the souvenir boat.
Cross multiply:
24b = 9*3
b = 27/24
= 1 1/8 inches.
Answer:
<u>The area of a pizza made in that circular pan is 452.39 inches²</u>
Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
Diameter of the circular pan = 24 inches
Radius of the circular pan = 24/2 = 12 inches
2. What is the area of the pizza?
Let's use the formula of the area of a circle, this way:
Area = π * r²
Substituting with the real values, we have:
Area = 3.1416 * 12²
Area = 452.39 inches²
<u>The area of a pizza made in that circular pan is 452.39 inches²</u>
I and 4i
let's say if you have i you can automatically think there is a one in front of it so one term like this (i) could look like this 1i and any number with the same variable or letter are like terms
hope this helps
