Answer 1

To find the cost for 1 pencil, we need to determine the cost per pencil by dividing the total cost by the quantity.

Using the given table, the cost for 1 pencil is calculated as follows:

Cost per pencil = Total cost / Quantity

Cost per pencil = $3.00 / 12 pencils = $0.25

Therefore, the cost for 1 pencil is $0.25.

Answer 3

To find the number of centimeters in 1 inch, we need to determine the ratio of centimeters to inches by dividing the given values of centimeters by inches.

Using the given table, the ratio of centimeters to inches is calculated as follows:

Ratio of centimeters to inches = Centimeters / Inches

Ratio of centimeters to inches = 12.7 cm / 5 inches = 2.54 cm/inch

Therefore, there are 2.54 centimeters in 1 inch.

Answer 5

To determine the unit rate for 1 bag of chips, we need to divide the total cost by the quantity of bags.

Using the given equation, we have 5y=$6.25x.

We can rewrite this equation as y = ($6.25/5)x to determine the unit rate or cost per bag.

Unit rate = ($6.25/5) = $1.25

Therefore, the unit rate for 1 bag of chips is $1.25.

Answer 6

John runs a marathon (26.2 miles) in 4 hours. Determine how many miles he runs per hour if the proportional relationship is represented by 4y=26.2x.(1 point)
Responses

Answer 7

To determine how many miles John runs per hour, we need to divide the total distance by the total time.

Using the given equation, 4y = 26.2x, we can rewrite it as y = (26.2/4)x to determine the miles per hour.

Miles per hour = (26.2/4) = 6.55

Therefore, John runs approximately 6.55 miles per hour.

Answer 9

To determine the number of centimeters in 1 inch, we need to divide the total centimeters by the quantity of inches.

Using the given equation, 6y = 15.24x, we can rewrite it as y = (15.24/6)x to determine the number of centimeters per inch.

Number of centimeters per inch = (15.24/6) = 2.54 centimeters

Therefore, there are 2.54 centimeters in 1 inch.
