the population of the world is approximately 6200 million people. it is increasing by approximately 93 million people each year. use this information to calculate the percentage increase in the population over a year.

Answers

Given:
approximate population: 6,200 million
approximate increase: 93 million

Percentage increase:

93,000,000 / 6,200,000,000 = 0.015
0.015 x 100% = 1.5% increase

What is the name of the relationship between 1 and 4? Parallel Lines and Transversals A. corresponding angles B. alternate interior angles C. obtuse angles D. adjacent angles

Answers

The correct answer is B. alternate interior angles. Both angles are on the inside of the two parallel lines, making them interior angles, and they are alternate because they're not on the same sides of the transversal line (the line that cuts through the parallel lines). A is incorrect because corresponding angles are those that are in the same position on both parallel lines, C is incorrect because it's impossible to tell with the information given if the angles are obtuse, and D is incorrect because adjacent angles are those that are next to each other.

Answer:

The correct anwser is B hope this helps :)

A Right Triangle (ABC) has sides measuring 3 inches and 4 inches. The hypotenuse is 5 inches. A similar right triangle (A'B'C') is created with sides of 7.5 and 10. What is the length of the hypotenuse? (Show all work)

Answers

Answer:

The length of hypotenuse is 12.5

Step-by-step explanation:

First 7.5 x 7.5 = 56.25

Then 10 x 10 = 100

Add them together 56.25 + 100 = 156.25

Then square root 156.25 and you get 12.5

Answer:

12.5 in.

Step-by-step explanation:

You could use the pythagorean theorem, or you can use scale factor. The scale factor between side A and A' is 7.5/3=2.5, which is your scale factor. Multiplying 2.5 by your original hypotenuse gives you 12.5

Estimate the sum of 502 and 47 by rounding both values to the nearest ten. What is the best estimate of the sum?

Answers

Nearest tenth of 502 is = 500
Nearest tenth of 47 = 50

So, the sum is = 500 + 50 = 550

In short, Your Answer would be 550

Hope this helps!
 my best estimate would be 550
