Explanation

To find the percentage of spaces reserved, divide the number of shaded spaces by the total number of spaces and multiply by 100.

Number of shaded spaces = 8

Total number of spaces = 20

Percentage reserved = (8 / 20) * 100 = 40%

Explanation

Weight of 1 apple = 2 kg ÷ 4 = 0.5 kg

Weight of 10 apples = 0.5 kg × 10 = 5 kg

Explanation

Let's solve the expression 3(a ÷ b)^c with the given values: a = 36, b = 12, and c = 2.

First, calculate a ÷ b = 36 ÷ 12 = 3.

Then, raise it to the power of c: 3^2 = 9.

Finally, multiply by 3: 3 * 9 = 27.

Explanation

Flour per person = 3 cups ÷ 10 people = 0.3 cups per person

For 15 people: 0.3 × 15 = 4.5 cups

Explanation

Cost per bag = $10.32 ÷ 8 = $1.29

For 20 bags: $1.29 × 20 = $25.80
