At the grocery store, pretzels are $2.40 for a 12-ounce bag and $18.00 for a 60-ounce container. Maria wants to get 60 ounces for a party she is hosting. How much will Maria save per ounce by making the less expensive selection?(1 point)

To find out how much Maria will save per ounce, we need to subtract the cost per ounce of the less expensive selection from the cost per ounce of the more expensive selection.
For the 12-ounce bag:
Cost per ounce = $2.40 ÷ 12 = $0.20/ounce
For the 60-ounce container:
Cost per ounce = $18.00 ÷ 60 = $0.30/ounce
Maria will save $0.30 - $0.20 = $0.10 per ounce by making the less expensive selection.
In planning for a dinner party, a planner orders 400 napkins for 8 guests. How many napkins should be ordered for 15 guests?(1 point)

6,000 napkins
To find out how many napkins should be ordered for 15 guests, we can set up a proportion.
We know that 400 napkins is enough for 8 guests.
Let's call the unknown number of napkins needed for 15 guests as "x".
So we can set up the proportion:
400 napkins / 8 guests = x napkins / 15 guests
Cross-multiplying, we get:
8 * x = 400 * 15
8x = 6000
x = 6000 / 8
x = 750
Therefore, 750 napkins should be ordered for 15 guests.

Since the chef uses 2 cups of broth for every 1/3 cup of rice, we can set up a proportion to find out how many cups of broth are needed for 6 cups of rice.
2 cups of broth / 1/3 cup of rice = x cups of broth / 6 cups of rice
Cross-multiplying, we get:
(2 cups of broth) * (6 cups of rice) = (1/3 cup of rice) * (x cups of broth)
12 cups of broth = 2 cups of rice * x
Dividing both sides by 2 cups of rice, we find:
x = 12 cups of broth / 2 cups of rice
x = 6 cups of broth
Therefore, 6 cups of broth are needed for 6 cups of rice.

2 kiloliters
To convert liters to kiloliters, you divide the number of liters by 1,000.
In this case, we want to convert 200 liters to kiloliters:
200 liters / 1,000 = 0.2 kiloliters
Therefore, there are 0.2 kiloliters in 200 liters.

To find out how many centimeters are in 3 feet 6 inches, we need to convert each measurement to centimeters and then add them together.
First, let's convert 3 feet to inches. Since 1 foot is equal to 12 inches, we have:
3 feet * 12 inches/foot = 36 inches
Next, let's convert 36 inches to centimeters. Since 1 inch is equal to approximately 2.54 centimeters, we have:
36 inches * 2.54 centimeters/inch = 91.44 centimeters
Now, let's convert 6 inches to centimeters:
6 inches * 2.54 centimeters/inch = 15.24 centimeters
Finally, we add the two measurements together to find the total in centimeters:
91.44 centimeters + 15.24 centimeters = 106.68 centimeters
Therefore, there are approximately 106.68 centimeters in 3 feet 6 inches.
A train travels 3 km per minute. What is the train’s speed in miles per hour? There are about 1.6 kilometers in 1 mile.

112.5 miles per hour
112.5 miles per hour
180 miles per hour
To find the train's speed in miles per hour, we need to convert the speed from kilometers per minute to miles per hour.
Since there are about 1.6 kilometers in 1 mile, we can multiply the speed by 1 mile/1.6 kilometers to convert from kilometers to miles.
3 km/minute * 1 mile/1.6 km = 1.875 miles/minute
To convert to miles per hour, we need to multiply by the number of minutes in an hour.
1.875 miles/minute * 60 minutes/hour = 112.5 miles/hour
Therefore, the train's speed is approximately 112.5 miles per hour.
