5.4/0.67 = 8.0597 

300

A salami that is 4 1/4 inches long is cut into 1/7 -inch slices. How many slices of salami are produced? Enter the answer.

__ slices

(4+(1/4)) / (1/7) = 29 3/4

400

Ms. R buys a $15 binder for her baseball cards. The baseball cards cost $7 per box.

What expression represents the amount of money, in dollars, it costs Ms. R to buy x boxes of baseball cards with a binder? Enter the answer.

And, how much does Ms. R spend if she buys 12 boxes of cards and a binder?

15 + 7x

500

Define interquartile range and MAD in your own words. How do I find them?

1. Arrange the data from least to greatest
2. Find the median
3. Split the data into two halves using the median
4. Find the median of the lower half of the data, which is quartile 1 (Q1)
5. Find the median of the upper half of the data, which is quartile 3 (Q3)
6. Subtract Q1 from Q3 to find the IQR

MAD:  represents the average distance between each data point in a set and the mean of that set, essentially indicating how spread out the data is

Unit 5

100

Find the area for a parallelogram if b = 4in and h = 15in

60in²

200

find the area of a triangle if b = 5mi and h = 8mi

5 x 8 = 40

40 / 2 = 20mi²

300

find the area for a trapezoid if a = 3m, b = 5m, and h = 9m

(3 + 5)/2 = 4

4 x 9 = 36m²

400

find the surface area of a square pyramid if h = 3cm and b = 6cm(base of a square is 6cm for all sides)

Triangles: (6 x 3)/2 = 9cm² x 4 = 36 cm² 

6 x 6 = 36cm²

36 + 36 = 72cm²

500

Find the surface area for a rectangular prism if l = 3cm, h = 5cm, and w = 6cm

2(3x6) + 2(6x5) + 2(5x3) = 126cm² 

Unit 6

100

Are these expressions equivalent? 

2x + 3x - 5 + 7

and

4x + x - 10 + 2

Yes!

200

Distribute to find the final expression:

3(x + 12) + 4x - 20

3x + 36 + 4x - 20

7x + 16

300

Evaluate the following expression:

2x² + 3x + 14 - 1x

x = 3

18 + 9 + 14 - 3 = 38 

400

Evaluate the following Expression:

2(x² + 3) - 12

x = 9

168 - 12= 156 

500

Evaluate the following Expression:

(x³+y²) + xy + 15

x = 10, y = 5

(10³+5²) + (10 x 5) + 15 = 220
