Suppose that 13 inches of wire costs 84 cents.

Question

At the same rate, how much (in cents) will 33 inches of wire cost?

Answer 1

To find the cost of 33 inches of wire, we can set up a proportion based on the given information: 13 inches costs 84 cents.

Using the proportion, we can set up the following equation:

13 inches / 84 cents = 33 inches / x cents

To solve for x (the unknown cost), we can cross-multiply and solve for x.

13 * x = 33 * 84

x = (33 * 84) / 13

x ≈ 213.23

Therefore, 33 inches of wire will cost approximately 213.23 cents.

Answer 2

Jessica drove 715 miles in 13 hours.
At the same rate, how long would it take her to drive 275 miles?

Answer 3

To find out how long it would take Jessica to drive 275 miles, we can set up a proportion based on the given information: 715 miles in 13 hours.

Using the proportion, we can set up the following equation:

715 miles / 13 hours = 275 miles / x hours

To solve for x (the unknown time), we can cross-multiply and solve for x.

715 * x = 275 * 13

x = (275 * 13) / 715

x ≈ 5

Therefore, it would take Jessica approximately 5 hours to drive 275 miles at the same rate.

Answer 4

Jim made $234 for 13 hours of work.
At the same rate, how much would he make for 9 hours of work?

Answer 5

To find out how much Jim would make for 9 hours of work at the same rate, we can set up a proportion based on the given information: $234 for 13 hours.

Using the proportion, we can set up the following equation:

$234 / 13 hours = x / 9 hours

To solve for x (the unknown amount), we can cross-multiply and solve for x.

$234 * 9 = 13 * x

$2106 = 13 * x

Divide both sides of the equation by 13:

x = $2106 / 13

x ≈ $162

Therefore, Jim would make approximately $162 for 9 hours of work at the same rate.
