During 2002 a town had a total snowfall of 92 inches, which was an increase of 15% from the previous year. What was the total snowfall in the previous year?

Answers

1.) Divide 92 by 100 so that it can be 100 pieces or 100% 92/100= 0.92
2.) Multiply the 15% be 0.92 to get how much more inches in snow that they got this year than last year. 15 X 0.92= 13.8
3.) Since we have how much more inches of snow they got all we need to do is subtract 13.8 from 92. 92-13.8= 78.2
4.) In the previous year the town had received 78.2in of snow.
I hope this helps :)

The town received 78.2 inched of snow the previous year

Compare and contrast the Pythagorean theorem, a circle, and the distance formula

Answers

Answer:

The distance formula is a formalization of the Pythagorean Theorem using x and y coordinates. In other words, they are the same thing in two seemingly different contexts. Every point (x,y) on the circle is related to the circle's center (a,b) by the fact that the distance between the point and the center is a constant (the radius of the circle, r). Equation of a circle is exactly the Pythagorean theorem with specific values plugged in.
