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.
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.
Elysse paid for her sandwich and drink with a $10 bill and received $0.63 in change. The sandwich cost $7.75 and sales tax was $0.47. What was the cost of her drink?
Given
Elysse paid for her sandwich and drink with a $10 bill and received $0.63 in change.
The sandwich cost $7.75 and sales tax was $0.47.
Find out the cost of her drink
To proof
Let the cost of her drink be x.
As given in the question
Elysse paid for her sandwich and drink with a $10 bill and received $0.63 in change.
Elysse paid for her sandwich and drink = 10 - 0.63
= $ 9.37
sandwich cost $7.75 and sales tax was $0.47
Than the equation becomes
x = 9.37 - (7.75 + 0.47)
x = 9.37 - 8.22
x = $ 1.15
The cost of the drink is $ 1.15.
Hence proved
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.

A rectangular garden sits next to a house. Three sides of the garden are fenced, and the fourth side is the house. The length of the garden is 9 meters. A total of 21.5 meters of fencing is used. If w stands for the width of the garden in meters, which equation can be used to find its width?
To find the width of the rectangular garden, use the equation 2w + 9 = 21.5, which leads to a width of 6.25 meters after solving step by step. The total fencing used is 21.5 meters for the three sides, with the fourth side being the house.
Finding the Width of the Rectangular Garden
Given that three sides of the rectangular garden are fenced and the fourth side is the house, let's break down the problem step by step:
The length of the garden is given as 9 meters.A total of 21.5 meters of fencing is used for the three sides.We need to find the width w of the garden.Since only three sides are fenced, the total length of the fencing is the sum of two widths and one length of the garden. Therefore, we can write this equation:
2w + 9 = 21.5
To find w, we solve the equation as follows:
Subtract the length from the total fencing: 2w = 21.5 - 9Calculate the difference: 2w = 12.5Divide by 2 to isolate w: w = 12.5 / 2Final result: w = 6.25 metersTherefore, the width of the garden is 6.25 meters.
