To find the answer, you must find the midpoint of their x-coordinates and their y-coordinates. To do that, you take the average between their x and y-coordinates.
So, in this case, it is:
x: (12+12)/2 = 24/2 = 12
y: (7-3)/2 = 4/2 = 2
So, the answer is: (12,2)
The answer is y=16/5x+5/2
Answer:
According to the model, in 2025 the world population will be 8,493,750,000
Step-by-step explanation:
Rate at which population was growing per year = 0.09125 billion
Initial population figure in 1990 = 5.3 billion
World population prediction in 2010 ;
Predicted population figure :
Initial population + (population growth value per year * number of years)
number of years = (2025 - 1990) = 35 years
Predicted population figure in 2025 :
5.3 + (0.09125 * 35)
5.3 + 3.19375
= 8.49375 billion.
8,493,750,000 by 2025

- Circumference of a Circle Formula: C = πd
Step-by-step explanation:
<u>Step 1: Define</u>
Circumference <em>C </em>= 141.3 ft
<u>Step 2: Solve for </u><em><u>d</u></em>
- Substitute in <em>C</em> [Circumference Formula]: 141.3 ft = πd
- Substitute in π (approximation): 141.3 ft ≈ 3.14d
- [Division Property of Equality] Divide both sides by 3.14: 45 ft ≈ d
- Rewrite: d ≈ 45 ft
