Which of the following would NOT be a line

a.) 4x - 8y = 32

b.)  y = 2x2 + 10

c.) y = -1

d.) x = 15

b.) y = 2x2 + 10

What is the circumference of a circle that has a radius of 4 cm

C = 2(pi)(r)
C = 2(3.14)(4)
C = 25.12

Therefore the circumference is around 25.12 cm.

If a car is driving at 20 km / hr, what would be the algebraic expression for its speed in relation to the distance travelled? (Let t represent time and D represent distance)

a) t = 20D
b) D = 20t
c) D = 20 - t
d) t = 20 + D

b) D = 20t

If the measurement of one of the angles in a right triangle is 40 degrees, what is the measurement of the other angle?

Sum of all angles in a triangle is 180 so:

180-90-40 = 50

Therefore the last angle is 50 degrees.

If there are 2.2 pounds in a kilogram, how much does a 20 kilogram brick weigh in pounds?

1 kg = 2.2 lbs.

x20

20 kg = 44 lb

Therefore the brick weighs 44 lbs.

Solve for x:

24 = x + 15

24 (-15) = x + 15 (-15)

x = 9

Check: 9+ 15 = 24

If Ms. Krol watches 2 movies every month, how many movies would she watch in a year?

2 movies x 12 months = 24 

Therefore Ms. Krol watches 24 movies a year

If a pizza costs $10 and an additional 50 cents per topping, what would the algebraic expression be for total cost? (Remember to define your variables)


Let n represent number of toppings and C represent total cost.

C = 0.5n + 10

x/4 + 10= -2

x = -48

400

What is the percentage of months in the year that start with the letter J?

3 (January, June, July) out of 12 months is one quarter of all the months or 25%

Therefore 25% of the months start with the letter J.

Create an expression for the area of the rectangle.

A = 25x-20x

23 is 29% of what number?

x(0.29) = 23

x = 79

400

Solve for x:

2x + 22 = 8

2x + 22 = 8

2x + 4 = 8

2x + 4 (-4) = 8 (-4)

2x (÷2)  = 4 (÷2)

x = 2

500

What is the ratio of total students to right-handed students based on this information:

- total students:30
- 10% of students are left-handed

10% of 30 is 3 so 3 students are left handed.

Therefore the ratio of 

total students to right-handed students is:

 30:3 or 30 to 3.

Rearrange the following standard equation to slope y-intercept form. 

4x + 2y = 10

2y = 10 - 4x 

y = 5 - 2x

y = -2x + 5

500

What are the side lengths of a cube if the volume is 64 cm3?

Volume = L x W x H (L = W = H)

64 = L x W x H 

64 = 4 x 4 x 4 (or cube root of 64)

Therefore the side lengths are 4cm.

If student A is working a part time job that pays $15 an hour and gets a raise of 2% every year, what would be their hourly pay after working for 4 years?

2% of $15 is 0.3 or 30 cents 

so after 3 years: 0.3 x 4 = $1.20

15.00 + 1.20 = 16.2

Therefore, the hourly rate would be $16.20.
