Jada surveyed some students to see which tool they most favored for communicating with grit. The results of her survey are shown

nikklg [1K]

Answer:

120 students did Jada survey

Step-by-step explanation:

* Lets explain how to solve the problem

- 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

- Assume that the total number of the students in the survey is x

∵ 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 $\frac{5}{12}$ of x equivalent to 50

∴ $\frac{5}{12}*x=50$

- 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

Janey paints a block of wood with gold glitter for an art project. The block measures 8 inches by 10 inches by 20 inches. After

goldenfox [79]

160 square inches

if the block is cut after it’s been painted, two sides with the same measurements don’t have glitter on them. you find the area of the one rectangle and multiply it by 2 as follows:
A = length • width
A = 10 • 8 = 80
area that needs to be covered = 80 • 2 = 160 square inches
