Historians estimate that there were about 7 million people on the earth in 4,000 BCE. Now there are about 7 billion! We write 7

million as 7,000,000. We write 7 billion as 7,000,000,000. How many times more people are there on the earth now than there were in 4,000 BCE? Explain your reasoning

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:

*<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 \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

Answer:

m = -3

Step-by-step explanation:

Slope Formula: m = \frac{y2-y1}{x2-x1}

Simply plug in our coordinates to find slope:

m = (11 - 2)/(5 - 8)

m = 9/-3

m = -3
