Johnny ran around a circular track 4 times. The distance for one time around was 900 meters. When he was done running he walked across the center to the other side. How far did he walk? Round to the nearest whole number
Answer: 287 meters
Explanation:
C=pid So, 900=3.14d. To get d by itself divide 3.14 by both sides. So, 900/3.14=(3.14d)/3.14
900/3.14=286.6242038

If this pyramid has a volume of 2112 cm3. What is its height?
(hint: sometimes you have to work backward)
Answer: 11 cm3
Explanation:
Volume of a pyramid =1/3 Bh
So, we will have to work backward to find the height: 2112=1/3 (24x24)h
2112=192h Now to get h by itself divide it into 2112:
2112/192=(192h)/192

A boy leaves home to go to the store. He rides his bike 5 miles north then turns east and rides for 4 miles. If you were to draw a straight line from the store to his house, how far away is he? Round to the nearest tenth.
(hint: Pythagoras probably know this)
Answer: 6.4
Explanation:
Pythagorean Theorem = a2 + b2 = c2
52 + 42 = c2
25 + 16 = 41
c2=41, get c be itself do the opposite operation of a square which is a square root. So,
c=sqrt41 so c=6.403124237

If this spinner is spun twice, what is the probability that it will land on blue both times?
Answer: 1/16
Explanation:
probability in one spin is 1 out of 4, or 1/4
the probability for the second spin is also 1 out of 4, or 1/4
now multiple both chances together:
1/4 x 1/4=1/16
Bonus: What is this as a percent?

The function of P(x) = 20x2
What is the average rate of change between
x=1.5 and x=3?
Answer: 90
Explanation:
P(1.5)=20 (1.52)
P(1.5)=45
P(3)=20(32)
P(3)=180
Using the Slope formula:
(180-45)/(3-1.5)
135/1.5

What is the surface area of this cylinder? (hint: a cylinder is 2 circles and a rectangle)
Answer: 923.16 in2
Explanation:
Area of a circle: pir^2
3.14(72) = 3.14 x 49 = 153.86
there are 2 circles so, 153.86 x 2 = 307.72
Next, area of a rectangle is l x w length of 14 and width of C=pid
So, 3.14 x 14 x14 = 615.44
Next add areas together: 307.72 + 615.44 = 923.16

Find the slope
x+2y=-8
Answer:
-1/2
Explanation:
Solve for y because the y-intercept formula is y=mx+b and m is the slope on the line.
x+2y=-8
to get y by itself subtract x from both sides (because it is a positive x you do the opposite operation)
x-x+2y=-8-x So, 2y=-8-x
Then to get y by itself divide 2 by both sides because it is the opposite operation or multiplication.
(2y)/2=(-8-x)/2
y=-4-1/2x, the slope is the number with the x, -1/2
