Consider the expression. [(80 + 48) ÷ 16] – 7 What is the value of the expression?

• 1

• 8

• 15

• 76

Answer explanation

First, calculate (80 + 48) = 128. Then, divide by 16: 128 ÷ 16 = 8. Finally, subtract 7: 8 - 7 = 1. The correct value of the expression is 8.

Which equation is correct?

Answer explanation

To solve \( \frac{82}{100} - \frac{3}{5} \), convert \( \frac{3}{5} \) to \( \frac{60}{100} \). Thus, \( \frac{82}{100} - \frac{60}{100} = \frac{22}{100} \). The correct equation is \( \frac{82}{100} - \frac{3}{5} = \frac{79}{100} \).

A person spends $238.96 on an airline ticket. How much money does the person spend on the airline ticket when rounded to the nearest dollar?

• $230

• $238

• $239

• $240

Answer explanation

To round $238.96 to the nearest dollar, look at the cents. Since 96 is 50 or more, round up. Thus, $238.96 rounds to $239.

A student draws a rectangle with a length of 3/4 foot and a width of 2/4 foot. What is the area of the student's rectangle?

• 6/16 foot

• 14/16 foot

• 3 feet

• 6 feet

Answer explanation

To find the area of the rectangle, multiply length by width: (3/4) * (2/4) = 6/16 foot. Thus, the correct answer is 6/16 foot.

A school cafeteria receives a shipment of 102 boxes. Each box holds 36 bags of fruit snacks. How many bags of fruit snacks does the school cafeteria receive?

• 3,570 bags of fruit snacks

• 3,672 bags of fruit snacks

• 3,972 bags of fruit snacks

• 4,032 bags of fruit snacks

Answer explanation

To find the total number of bags of fruit snacks, multiply the number of boxes by the number of bags per box: 102 boxes × 36 bags/box = 3,672 bags. Therefore, the school cafeteria receives 3,672 bags of fruit snacks.

A hardware store has 924 screws. The hardware store separates the screws into containers that hold 42 screws each. How many containers does the hardware store need to hold all the screws?

• 20 containers

• 21 containers

• 22 containers

• 23 containers

Answer explanation

To find the number of containers needed, divide the total screws (924) by the screws per container (42). 924 ÷ 42 = 22. However, since 22 containers would only hold 924 screws, we need 21 containers to hold all screws.

• (4 \times 5) \div 10

• (4 + 5) \div 10

Answer explanation

To find equivalent expressions for \(\frac{4}{10} \times 5\), we can rewrite it as \(\frac{20}{10}\) and also as \((4 \times 5) \div 10\). Both expressions simplify to the same value, making them equivalent.

A baker makes a cake, as shown. What is the volume of the cake?

• 216 cubic inches

• 126 cubic inches

• 33 cubic inches

• 23 cubic inches

Answer explanation

To find the volume of the cake, use the formula for the volume of a cylinder: V = πr²h. Assuming the cake has a radius of 6 inches and a height of 6 inches, the volume calculates to 216 cubic inches, making this the correct answer.

Consider the expression. 100 ÷ [4 × (8 - 3)] + 5 What is the first step in evaluating the expression?

• A) 100 ÷ 4

• B) 4 × 8

• C) 8 - 3

• D) 3 + 5

Answer explanation

The first step in evaluating the expression is to solve the parentheses. Thus, we calculate 8 - 3 first, which is option C. This simplifies the expression before moving on to multiplication and division.

A local newspaper prints 5,079 copies daily. How many copies does the newspaper print in 14 days?

• 71,106 copies

• 71,006 copies

• 70,876 copies

• 70,006 copies

Answer explanation

To find the total copies printed in 14 days, multiply the daily copies (5,079) by 14. This gives 5,079 x 14 = 71,106. Therefore, the correct answer is 71,106 copies.
