1) By what number do you divide 10 by to get -2?

-8

-5

5

8

To find the number by which 10 should be divided to get -2, we can use the formula: dividend ÷ divisor = quotient. In this case, the dividend is 10 and the quotient is -2. Rearranging the formula, we get: divisor = dividend ÷ quotient. Therefore, the divisor is 10 ÷ -2, which equals -5. Hence, the correct answer is -5.

6) Lydia has a piece of fabric that is 8.32 meters long. She cuts it into 8 pieces of equal length. How long is each piece of fabric?

14 meters

1.4 meters

1.14 meters

1.04 meters

Lydia has a piece of fabric that is 8.32 meters long. She cuts it into 8 pieces of equal length. To find the length of each piece, we divide the total length of the fabric (8.32 meters) by the number of pieces (8). The calculation is 8.32 meters ÷ 8 = 1.04 meters. Therefore, each piece of fabric is 1.04 meters long.

7) The area of a square patio is 64 square feet. What is the width of the patio?

4 ft

8 ft

16 ft

32 ft

The area of a square is found by multiplying the length of one side by itself. In this case, the area of the patio is given as 64 square feet. To find the width, we need to find the length of one side of the square. Taking the square root of 64 gives us 8, which represents the length of one side. Therefore, the width of the patio is 8 ft.

10) A package of 4 Brand A pens costs $2.60. A package of 10 Brand B pens costs $6.00. Compare the unit prices.

Brand A costs 5 cents more per pen

Brand A costs 6 cents more per pen

Brand B costs 6 cents more per pen.

The pens cost the same price.

Brand A costs 5 cents more per pen compared to Brand B. This can be determined by calculating the unit price for each brand. For Brand A, the unit price is $2.60 divided by 4 pens, which equals $0.65 per pen. For Brand B, the unit price is $6.00 divided by 10 pens, which equals $0.60 per pen. Therefore, Brand A costs 5 cents more per pen than Brand B.
