Two quarts of ice cream cost $5.48. How much does 1 pint cost? (Remember to convert : 2 pints=1 quart)

Since 2 pints equal 1 quart, we know that 1 quart of ice cream costs $5.48/2 = $<<5.48/2=2.74>>2.74.

Therefore, 1 pint of ice cream costs $2.74. Answer: \boxed{2.74}.

John earns $500 in a work week. A regular work week for John consists of 5 work days with 8 hours a day. How much does John earn each hour?

To find out how much John earns per hour, we first need to determine the total number of hours he works in a week.

There are 5 work days in a week, and each day consists of 8 hours. So, John works a total of 5 days * 8 hours = 40 hours in a week.

Next, we divide the total earnings for the week, which is $500, by the number of hours worked, which is 40 hours.

Thus, John earns $500/40 hours = $<<500/40=12.50>>12.50 per hour. Answer: \boxed{12.50}.

A proportional relationship has a unit rate of 4 to 1. Which situation below represents this relationship?

In a proportional relationship, the ratio between two quantities remains constant. A unit rate of 4 to 1 means that for every 4 units of the first quantity, there is 1 unit of the second quantity.

Therefore, the situation below represents this relationship:
- For every 4 gallons of gas, a car can travel 1 mile.

A proportional relationship has a unit rate of 4 to 1. Which situation below represents this relationship?

A) A tire warehouse has exactly 12,800 automobile tires for 3,200 automobiles
B) Hikers travel 48 miles in 6 hours
C) A DJ is required to play 60 songs over a 4-hour shift
D) A cookie recipe uses 1 3/4 cups of brown sugar for 2 batches

The situation that represents a proportional relationship with a unit rate of 4 to 1 is:

D) A cookie recipe uses 1 3/4 cups of brown sugar for 2 batches.

In this situation, the ratio of brown sugar to batches is 1 3/4 cups of brown sugar to 2 batches, which simplifies to a ratio of 7/4 cups of brown sugar to 2 batches. This ratio is equivalent to 4/1, representing a proportional relationship with a unit rate of 4 to 1.

An Alien is 5 feet tall. His shadow is 8 feet long. At the same time of the day, a tree's shadow is 32 feet long. What is the height of the tree?

To solve this problem, we can set up a proportion using the heights and shadows.

Let's say "h" represents the height of the tree. The ratio of the Alien's height to its shadow is 5 feet to 8 feet. The ratio of the tree's height to its shadow is "h" feet to 32 feet.

Using these ratios, we can set up the proportion:

(5 feet) / (8 feet) = h feet / (32 feet)

To solve for "h", we can cross-multiply:

8 feet * h feet = 5 feet * 32 feet

8h = 160

Finally, divide both sides by 8 to find the height of the tree:

h = 20

Therefore, the height of the tree is 20 feet. Answer: \boxed{20}.

Polygon KLMN is similar to polygon PQRS. What is the length of QR?

Without more information about the polygons or their similarity, we cannot determine the length of QR. The lengths of corresponding sides in similar polygons are proportional, but we need additional information, such as the length of a known side or the ratio of corresponding side lengths, to find the length of QR.
