the pizzeria buys 250 pounds of mozzarella cheese if they use 20 5/6 pounds of cheese every day how long will the cheese last
To determine how long the pizzeria's cheese supply will last, we divide 250 pounds by the daily usage of 20 5/6 pounds, which equals approximately 12 days.
Explanation:To calculate how long the pizzeria's 250 pounds of mozzarella cheese will last, given that they use 20 5/6 pounds of cheese every day, we have to divide the total amount of cheese by the daily usage. The fraction 5/6 needs to be converted to a decimal for ease of calculation. So 5/6 is approximately 0.833. Therefore, the daily usage is 20 + 0.833, which is 20.833 pounds.
Next, we divide the total amount of cheese by the daily usage to find how many days the cheese will last:
250 ÷ 20.833 ≈ 12 days
Therefore, the mozzarella cheese will last for approximately 12 days.

You purchase a car using a $20,000 loan with a 5% simple interest rate.
(a) Suppose you pay the loan off after 4 years. How much interest do you pay on your loan? Show your
work and don’t forget the unit!
(b) Suppose you pay the loan off after 3 years. How much interest do you save by paying the loan off
sooner? Show your work and don’t forget the unit.
Answer: a) b)
The total interest paid on a $20,000 loan at 5% simple interest over 4 years is $4,000.
To solve part (a) of the question, we calculate the amount of interest paid on a $20,000 loan over 4 years with a 5% simple interest rate:
Calculate the annual interest: $20,000 * 5% = $1,000.
Multiply the annual interest by the number of years: $1,000 * 4 years = $4,000.
The total interest paid after 4 years is $4,000.
For part (b), to find the interest saved by paying off the loan after 3 years instead of 4 years, we do the following:
Calculate the interest for 3 years: $1,000 imes 3 years = $3,000.
Deduct the 3-year interest from the 4-year interest: $4,000 - $3,000 = $1,000.
The interest saved by paying the loan off after 3 years is $1,000.

Mateo bought 4.54 pounds of Fuji apples and 3.7 pounds of Golden Delicious apples.
How many more pounds of Fuji apples than Golden Delicious apples did he buy?
Mateo bought 0.84 pounds more of Fuji apples than Golden Delicious apples, calculated by subtracting 3.7 pounds (Golden Delicious) from 4.54 pounds (Fuji).
Mateo bought 4.54 pounds of Fuji apples and 3.7 pounds of Golden Delicious apples. To find out how many more pounds of Fuji apples he bought than Golden Delicious apples, you can simply subtract the weight of the Golden Delicious apples from the weight of the Fuji apples:
4.54 pounds (Fuji apples) - 3.7 pounds (Golden Delicious apples) = 0.84 pounds.
Mateo bought 0.84 pounds more of Fuji apples than Golden Delicious apples. This means that he purchased nearly 0.84 pounds extra of Fuji apples compared to the Golden Delicious variety.
It's important to remember that this calculation involves a straightforward subtraction of weights and doesn't require any complex mathematical operations. So, Mateo purchased approximately 0.84 pounds more of Fuji apples than Golden Delicious apples.

each week,steven gets an allowance of $8 plus $3 for each chore he does. his younger sister jill gets an allowance of $6 plus $2 per chore. write an expression for how much their parents give steven and jill each week if they do the same number of chores.
Final answer:
The expression representing the total weekly allowance Steven and Jill receive for doing the same number of chores is 14 + 5c, where c represents the number of chores done.
Explanation:
The question asks for an expression to represent the total allowance that Steven and Jill receive each week if they do the same number of chores. Steven gets a fixed allowance of $8 plus an additional $3 for each chore he completes, while Jill gets a fixed allowance of $6 plus $2 for each chore she completes.
Let's represent the number of chores they each do with the variable c. The expression for Steven's weekly allowance would be 8 + 3c, and the expression for Jill's weekly allowance would be 6 + 2c. To find the total combined allowance, we simply add the two expressions:
8 + 3c + 6 + 2c
Simplifying this expression, we combine like terms:
14 + 5c
This expression represents the total weekly allowance that their parents give to Steven and Jill together, if they do the same number of chores.

Carlos has 4 1/2 gallons of paint. To paint a room that is 10 ft by 10 ft, he uses 34 gallon of paint. How many 10 ft by 10 ft rooms can Carlos paint? A. 4 1/3 rooms B. 4 2/3 rooms C. 6 rooms D. 9 rooms
Carlos can paint 6 rooms with the available 4 1/2 gallons of paint.
To paint one 10 ft by 10 ft room, Carlos uses 3/4 gallons of paint. To find how many rooms Carlos can paint with the available 4 1/2 gallons of paint, we divide the total paint available by the paint used per room.
Number of rooms = Total paint available / Paint used per room
Number of rooms = 4 1/2 / 3/4
Number of rooms = 9/2 / 3/4
To divide fractions, multiply by the reciprocal of the divisor
Number of rooms = 9/2 * 4/3
Number of rooms = 36/6
Number of rooms = 6
Carlos can paint 6 rooms with the available 4 1/2 gallons of paint. Therefore, the correct answer is C. 6 rooms.
