The main purpose of a dictionary is to provide definitions and pronunciation of words. It helps us understand the meaning and correct pronunciation of words in a language. Dictionaries are designed to give us information about the meaning, usage, and spelling of words. They contain definitions that explain the meaning of words, and also often provide guidance on how to pronounce them, including guides such as phonetic symbols or pronunciation guides. Therefore, the correct answer is option 1: to provide definitions and pronunciation of words.

Based on the given ratio of 1 pint = 2 cups, we can determine that 8 cups is equal to 4 pints.
Use the ratio 16 ounces = 1 pound. A suitcase weighs 176 ounces. How many pounds does the suitcase weigh?(1 point)
$$
To determine how many pounds the suitcase weighs, we need to use the given ratio of 16 ounces = 1 pound.
Let x be the weight of the suitcase in pounds.
We can set up the following equation to solve for x:
16 ounces = 1 pound
176 ounces = x pounds
Now, we can solve for x by cross-multiplying:
16 * x = 1 * 176
16x = 176
x = 176 / 16
x = 11
Therefore, the suitcase weighs 11 pounds.
Use the ratio 1,000 grams = 1 kilogram. How many grams are equal to 2.75 kilograms?(1 point)
To determine how many grams are equal to 2.75 kilograms, we need to use the given ratio of 1,000 grams = 1 kilogram.
Let x be the number of grams that are equal to 2.75 kilograms.
We can set up the following equation to solve for x:
1,000 grams = 1 kilogram
x grams = 2.75 kilograms
Now, we can solve for x by multiplying 2.75 by 1,000:
x = 2.75 * 1,000
x = 2,750
Therefore, 2.75 kilograms is equal to 2,750 grams.
Use the ratio 1 liter is equal to approximately 2.1 pints. How many pints are equal to 10 liters?(1 point)
To determine how many pints are equal to 10 liters, we need to use the given ratio of 1 liter ≈ 2.1 pints.
Let x be the number of pints that are equal to 10 liters.
We can set up the following equation to solve for x:
1 liter ≈ 2.1 pints
10 liters = x pints
Now, we can solve for x by multiplying 10 by 2.1:
x = 10 * 2.1
x = 21
Therefore, 10 liters is equal to approximately 21 pints.
Use the ratio 1 foot = 30.48 centimeters. Jeff is 183 centimeters tall. How many feet tall is he? Round to the nearest whole number.(1 point)
To determine how many feet tall Jeff is, we need to use the given ratio of 1 foot = 30.48 centimeters.
Let x be the height of Jeff in feet.
We can set up the following equation to solve for x:
1 foot = 30.48 centimeters
x feet = 183 centimeters
Now, we can solve for x by dividing 183 by 30.48:
x = 183 / 30.48
x ≈ 6
Therefore, Jeff is approximately 6 feet tall.

To determine how many meters of snow the town gets, we need to use the given ratio of 1 meter = 100 centimeters.
Let x be the amount of snow in meters.
We can set up the following equation to solve for x:
1 meter = 100 centimeters
x meters = 200 centimeters
Now, we can solve for x by dividing 200 by 100:
x = 200 / 100
x = 2
Therefore, the town gets 2 meters of snow.

To determine how many kilograms are equal to 72 pounds, we need to use the given proportion of 1 kilogram = 2.2 pounds.
Let x be the number of kilograms that are equal to 72 pounds.
We can set up the following proportion to solve for x:
1 kilogram / 2.2 pounds = x kilograms / 72 pounds
Now, we can cross-multiply and solve for x:
1 * 72 = 2.2 * x
72 = 2.2x
x = 72 / 2.2
x ≈ 32.7
Therefore, 72 pounds is approximately equal to 32.7 kilograms rounded to the nearest tenth. So the answer is 32.7.

To determine how many yards Martha runs in a race of 1,000 meters, we need to use the given ratio of 1 meter ≈ 1.09 yards.
Let x be the number of yards that Martha runs.
We can set up the following equation to solve for x:
1 meter ≈ 1.09 yards
1,000 meters = x yards
Now, we can solve for x by multiplying 1,000 by 1.09:
x = 1,000 * 1.09
x ≈ 1,090
Therefore, Martha runs approximately 1,090 yards in the race.

To determine Delta's speed in kilometers per hour, we need to convert miles per hour to kilometers per hour using the given conversion of 1 kilometer ≈ 0.62 miles.
Let x be Delta's speed in kilometers per hour.
We can set up the following proportion to solve for x:
1 kilometer / 0.62 miles = x kilometers / 17 miles
Now, we can cross-multiply and solve for x:
1 * 17 = 0.62 * x
17 = 0.62x
x = 17 / 0.62
x ≈ 27.4
Therefore, Delta's speed is approximately 27.4 kilometers per hour rounded to the nearest tenth. So the answer is 27.4.
