Corey bought 2 1/2 liters of paint for$60

what was the cost per liter of paint.

Answers

Answer 1

Answer:

we know that

Unit Rate is the ratio of two measurements in which the second term is $1$

we have

$2(1)/(2)\ liters=(2*2+1)/(2)=(5)/(2)\ liters$

Corey bought $(5)/(2)\ liters$ of paint for $\$60$

by proportion

Find the cost of one liter of paint

$(60)/((5/2))(\$)/(liters)=(x)/(1)(\$)/(liters) \n \nx*(5)/(2)=60\n \n x=2*60/5\n \nx=\$24$

therefore

the answer is

the cost per liter of the paint is equal to $24(\$)/(liter)$

Answer 2

Answer: if 2 1/2 liters of paint cost $60 then 1 liter cost $24

Hank estimated width of the door to his classroom in feet. what is a reasonable estimate?

Answers

The measurements of an average door are 80 inches by 36 inches. In this measurement, the length is 80 inches and the width is 36 inches. If Hank estimates the width of the door of his classroom, he will then most likely estimate it at 36 inches. To convert this into feet, you must know that 12 inches make 1 foot. So, 36 inches divided by 12 inches will convert the measurement to feet: 36/12 = 3. Thus, the answer is 3 feet.

A 16 1/2 kilometer stretch of road needs repairs. Workers can repair 2 1/4 kilometer of road per week.How many weeks will it take to repair this stretch of road?

Answers

Hello,

So the total length of the road is 16.5km (decimal form). Workers can repair 2.25 per week. To get the number of weeks they need to repair the road is to divide the total with per week. The equation would be:

$16.5 / 2.25 = 7.33$

or with fraction

16 2/4 / 2 1/4 = 7 1/3

Answer: The workers would need 7.33 weeks to repair the road.

Hope this helps.
