Answer:
Step-by-step explanation:
Let's calculate 10 pi.
1 pi is about 3.14.
10 pi should be about 31.4.
-31 to -1 is 31 integers.
1 to 31 is 31 more integers.
0 is 1 integer.
31 + 31 = 62
62 + 1 = 63
Hope this helped!

Step-by-step explanation:
My school supplyes us with a calculator and lucky for you it does scientific notation
Mean is all of the numbers added up and then divided by the number of the numbers. so for example; 32+36+38+39+42+43+44+47+49+50 divided by 10 do that and then group 2, and if you already know how to do that then answer the questions

Step-by-step explanation: 5 23 8 03
the lenght of the longer leg of a right triangle is 9 ft longer than the lenght of the shorter leg x. The hypotenuse is 9 ft shorter than twice the lenght of the shorter leg.
shorter leg = x
longer leg = x + 9
hypotenuse = 2x - 9
Pythagorean theorem = a² + b² = c²
shorter-leg² + longer-leg² = hypotenuse²
x² + (x+9)² = (2x - 9)² solve for x
x² + (x+9) (x+9) = (2x - 9)(2x - 9)
x² + (x²+18x+81) = (4x² - 36x + 81)
(2x²+18x+81) = (4x² - 36x + 81)
0 = 2x² -54x
0 = x(2x - 54)
0 = x and 0 = 2x -54
54 = 2x
27 = x
shorter leg = 27
longer leg = 36
hypotenuse = 45
divided all the values by 9 and you get a 3, 4, 5 right triangle, so the answer checks correct
