Answer:
A square has equal width and length. To find the area, you have to multiply the width by length but because they are the same length, you may some time see the formula written as L*L or .
The area of used up by the squares is 150sq feet. I found this by dividing 600 by 4. You can find an estimate by equating 150 the L*L. This gives you an approximate value of 12.
Answer:
120 students did Jada survey
Step-by-step explanation:
*<em> Lets explain how to solve the problem</em>
- The results of Jada survey are shown in this circle graph
# Communication tools Text messages 5/12
# Phone 1/5
# Emails 1/20
# Other messaging apps 1/3
- A total of 50 students said they favored text messages to
communicate with friends
- We need to find the total number of the students in Jada survey
- <em>Assume that the total number of the students in the survey is </em><em>x</em>
∵ The Communication tools Text messages expressed by a
fraction 5/12 of the circle graph
∵ The total of 50 students said they favored text messages to
communicate with friends
- That means The fraction of x equivalent to 50
∴
- Multiply both sides by 12
∴ 5x = 600
- Divide both sides by 5
∴ x = 120
∵ x represents the number of the students in Jada survey
∴ 120 students did Jada survey
Answer:
x =
Step-by-step explanation:
Given
=
( cross- multiply )
25 × 2x = 5 × 4
50x = 20 ( divide both sides by 50 )
x = =
