Which measures are equivalent to 10 meters? Mark all that apply.

• 0.01 kilometer

• 1,000 millimeters

• 100 millimeters

• 1,000 centimeters

Answer explanation

There are 1,000 meters in 1 kilometer, so 10 meters is equivalent to 0.01 kilometers (10 ÷ 1,000 = 0.01). There are 100 centimeters in 1 meter, so in 10 meters there will be 1,000 centimeters (10 x 100 = 1,000).

1,000 millimeters is 1 meter, and 100 millimeters is 0.1 meters, so they are not equivalent.

Which measures are equivalent to 3 feet? Mark all that apply.

• 36 inches

• 15 inches

• 1 yard

• 1/3 yard

Answer explanation

3 feet is equivalent to 36 inches (1 foot = 12 inches, so 3 feet = 36 inches) and 1 yard (1 yard = 3 feet). Therefore, the correct measures are 36 inches and 1 yard.

Which numbers round to 0.1 when rounded to the nearest tenth? Mark all that apply.

• 0.09

• 0.95

• 0.99

• 1.04

Answer explanation

When rounding to the nearest tenth, 0.09 rounds to 0.1 because it is closer to 0.1 than to 0.0. The other numbers (0.95, 0.99, 1.04) round to 1.0, not 0.1.

Which numbers round to 0.02 when rounded to the nearest hundredth? Mark all that apply.

• 0.025

• 0.023

• 0.026

• 0.019

Answer explanation

Numbers round to 0.02 when rounded to the nearest hundredth if they are between 0.015 and 0.024. Therefore, 0.023 and 0.019 round to 0.02, but 0.025 and 0.026 are bigger and round to 0.03.

• 7/8

• 7/16

• 1/14

• 1/16

Answer explanation

• 15 squares

• 20 squares

• 30 squares

• 10 squares

Answer explanation

To find the number of squares, convert the length of 1/2 meter to tenths. 1/2 becomes 5/10. The doormat is 5/10 meter long and 3/10 meter wide, meaning that 5 rows of 3 squares that measure 1/10 meter square can fit on the doormat, or 5 x 3. That is 15 squares.

The inside of a cooler is in the shape of a rectangular prism. The inside of the cooler is 20 inches wide, 14 inches high, and 12 inches long. What is the volume, in cubic inches, of the inside of the cooler?

V = l x w x h

• 46 cubic inches

• 3,360 cubic inches

• 17 cubic inches

• 254 cubic inches

Answer explanation

To find the volume of the cooler, use the formula V = l x w x h. Here, V = 12 in x 20 in x 14 in = 3,360 cubic inches. Thus, the correct answer is 3,360 cubic inches.

Which expressions represent the statement "three minus the product of seven and four"? Mark all that apply.

• 3 − (7 × 4)

• (7 × 4) − 3

• 3 − (4 ÷ 7)

• 3 − (4 × 7)

• (7 ÷ 4) − 3

Answer explanation

"Product" is the solution to a multiplication expression. The expression 3 − (7 × 4) correctly represents "three minus the product of seven and four". 3 − (4 × 7) is also valid since multiplication is commutative. The other options do not match the statement.

What is the value of the expression (4 × 5) + (10 × 30)?

• 49

• 90

• 320

• 900

Answer explanation

To solve (4 × 5) + (10 × 30), first calculate 4 × 5 = 20 and 10 × 30 = 300. These are calculated first because they are in parentheses. Then all that's left is to add them: 20 + 300 = 320. Therefore, the correct answer is 320.
