The answer would be 65.9%. Add both paper numbers together (26.5+51.3) which is to 77.8.. to find paper not recycled just put 51.3/77.8 which would be 0.659 as a decimal.. move the decimal over to the right twice and that'd be your percentage.

Henry knows that the circumference of a circle is 18mc006-1.jpg inches. What is the area of the circle?

lesantik [10]

The complete question is:
Henry knows that the circumference of a circle is 18π inches. What is the area of the circle?

Solution:
Circumference (C) of the circle can be written as:

$C=2 \pi r \\ \\ 18 \pi =2 \pi r \\ \\ r=9$

Using this value of radius, we can find the Area(A) of the circle.

$A= \pi r^{2} \\ \\ 
A= \pi (9)^{2} \\ \\ 
A=81 \pi$

Therefore, area of the circle having a circumference of 18π inches will be 81π inches²

Max went to the store and bought 22 apples. He bought twice as many red apples as he did green, and he bought one-third many yel

katrin [286]

Let the number of green apples bought be x

Green apples = x

Red apples = 2x

Yellow apples = 1/3 (2x) = 2/3 x

Total = 22 apples

x + 2x + 2/3 x = 22

11/3 x = 22

11x = 66

x = 6

Green apples = x = 6

Red apples = 2x = 2(6) = 12

Yellow apples = 2/3 (2x) = 2/3 (6) = 4

Answer: Green = 6, Red = 12, Yellow = 4

salantis [7]

0.10r + 0.20b = 24
3r = b + 20....b = 3r - 20

0.10r + 0.20(3r - 20) = 24
0.10r + 0.60r - 4 = 24
0.70r = 24 + 4
0.70r = 28
r = 28/0.70
r = 40 <=== there are 40 reds

0.10r + 0.20b = 24
0.10(40) + 0.20b = 24
4 + 0.20b = 24
0.20b = 24 - 4
0.20b = 20
b = 20/0.20
b = 100 <=== there are 100 blues
