If Skippy ran a total of 5 times around a circular track and the distance around the track was 0.5 km, how far did he run and how far did he have to walk to get from one side of the track to the other? Round to the nearest hundredth.
0.5 x 5 = 2.5 km
C = pi x D
0.5 = 3.14 x D
0.5/3.14 = 0.16 km
What is the mean for the following set of numbers?
4, 9, 56, 43, 23

-23 + -7(10 - -10) - 100/2 x 3 + (23 + 32) =
-23 - 70 - 70 - 150 + 55 =
-258
111x - 36 = -36-55-100
Solve for "x"
111x - 36 = -191
111x - 36 + 36 = -191 + 36
111x = -155
111x/111 = -155/111
x = 1 44/111
What is 6.32 times 5.1 divided by 3.1? Round to the nearest tenth.
10.4
What is the volume and total area of a cylinder with the following dimensions:
Diameter of the two ends is 8 cm
Length is 20 cm
Volume = pi x r x r x h
= 3.14 x 4 x 4 x 20 = 1004.8 cm cubed
C = pi x D C = 3.14 x 8 = 25.12
Area of two circles = 3.14 x 4 x 4 x 2 = 100.48
Area of rectangle = length x circumference of circle = 20 x 25.12 = 502.4
100.48 + 502.4 = 602.88 cm squared
Sue got 89%, 67%, 53% on her first three Math tests. What does she need on her fourth Math test to average 73%?
83%
123 X -3 + (12 x 2 -50) - 12 x 12 + 55/11 x (1 +1) + 0.5 =
-528.5
1/3b - 2/3b = 2(60-100)
Solve for "b"
-1/3b = 120 - 200
-1/3b = -80
-1/3b x -3 = -80 x -3
b = 240
