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.
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.

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.

A lamp shade has a radius of 9 inches. What is the circumference of the top of the shade? Use 3.14 to approximate pi. Round your answer to the nearest whole number.
Answer:
The circumference of the lamp shade is 57 inches.
Step-by-step explanation:
Given : A lamp shade has a radius of 9 inches.
To find : The circumference of the top of the shade
Solution : A lamp shade is in a sphere form,
So, formula to find the circumference of sphere is
[tex]C=2\pi r[/tex]
Now, the radius of lamp is 9 inches and [tex]\pi=3.14[/tex]
Substitute the value in the formula we get,
[tex]C=2\pi r[/tex]
[tex]C=2\times 3.14 \times 9[/tex]
[tex]C=56.52[/tex]

The ratio of the amount of almonds in Bag A to the amount of bag B was 8:5. After 12 ounces of almonds were transferred from Bag A to Bag B, the amount of almonds in Both bags became the same. How many ounces of almonds were originally in Bag B?
To solve this problem, we can set up an equation using the given information and solve for x. The original amount of almonds in Bag B was 40 ounces.
Explanation:To solve this problem, we can set up an equation using the given information. Let's assume that the original amount of almonds in Bag A is 8x ounces and the original amount of almonds in Bag B is 5x ounces.
After 12 ounces of almonds are transferred from Bag A to Bag B, the amount of almonds in both bags becomes the same. This means that the amount of almonds in Bag A is now 8x - 12 ounces and the amount of almonds in Bag B is now 5x + 12 ounces.
Setting up an equation based on the ratios, we have:
8x - 12 = 5x + 12
Solving for x, we find that x = 8.
Therefore, the original amount of almonds in Bag B was 5x = 5(8) = 40 ounces.

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.
what fraction is equivalent to 2/5 and has a denominator of 15
To find an equivalent fraction to 2/5 with a denominator of 15, multiply both the numerator (2) and the denominator (5) by 3, resulting in the fraction 6/15.
Explanation:To find a fraction equivalent to 2/5 that has a denominator of 15, we need to scale up the original fraction so that the denominator becomes 15. This is done by finding a number that you can multiply the denominator by to get 15. Since 5 × 3 = 15, we multiply both the numerator and denominator of 2/5 by 3 to maintain the same value.
Here's the calculation:
Multiply the numerator by 3: 2 × 3 = 6Multiply the denominator by 3: 5 × 3 = 15
Therefore, the fraction that is equivalent to 2/5 with a denominator of 15 is 6/15.
