Jeremy cleans his house in 2 1/2 hours.hunter cleans his house in 3 1/4 hours.how much longer does it take for Jeremy to clean his house?

Answers

well 3 1/4 is 3.25 and 2 1/2 is 2.50 and that subtracted is 0.75
It should be asking for how much longer it takes for Hunter to clean his house, since it says 3 and 1/2 hours. Jeremy only takes 2 and a half hour to clean, so it would be less than Hunter's time. I will help you with this problem, but I will do it with the question "How much longer does it take for Hunter to clean his house?", because the question above doesn't make sense to me.

This is all based on subtraction. You would take the fraction that is more than the other, and use it to subtract the less. You would always want the denominator to be the same, so lets switch it to 2 2/4. Now, you would do 1/4 minus 2/4, which gets you -1/4. You can use the whole hours and fill it in. Since the whole hours is 4/4, you would take 4/4+(-1/4). Simplify and you will get 4/4-1/4. And you would have 3/4.

Now, since the question is asking for how long it take for JEREMY for clean his house, you would say, "it takes -3/4 hours longer for Jeremy to clean his house, since Hunter really takes longer." (Everything in the quote is part of the answer)

kishauna rode her bike for 35 minutes each on Monday Wednesday and Saturday and 55 minutes each on Tuesday and Thursday. write an expression that shows the total amount of the time she spent riding her bike. than evaluate the expression

Answers

Since Kishauna rode her bike for 35 minutes on 3 days you are going to multiply 35 time 3 which equals 105.

And since she rode her bike 55 minutes on 2 other days you are going to multiply 55 times 2 and get 110.

Now you add 105 + 110 and your answer is 215.

The expression and the evaluation are that represents the total amount of time should be

[tex]= 35\times 3 + 55\times 2\\\\= 105 + 110[/tex]

and 215 minutes.  

Given that,

The bike should run for 35 minutes each on Monday Wednesday and Saturday.And, the 55 minutes each on Tuesday and Thursday.

Based on the above information, the calculation is as follows:

[tex]= 35\times 3 + 55\times 2\\\\= 105 + 110[/tex]

= 215 minutes

Therefore we can conclude that the expression that represents the total amount of time should be 215 minutes.

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.

Answers

the allowance expression would be 3x+8=2x+6

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.

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)

Answers

the answer is A) I=prt; I=20,000(.05)(4) = $4000 b) I = prt; I = 20,000(.05)(2) = $2000 $4000-$2000 = $2000. You save $2000 by paying it off in 2 years vs. 4 years

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

Answers

2 x 3 = 6 ( numerator) 5 x 3 = 15 ( denominator) 6/15 :) hope it was good to understand! ;)
Final answer:

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.

Juanita borrowed $600 to purchase a new computer. She was charged 7% interest for two years. She used the simple interest formula to find the interest.
I = 600(7)(2)
What error did Juanita make and how will her error affect the interest she calculates? Explain

Answers

First, you would write 7% as a fraction, 7/100. Then, you would write 600 as a fraction. Let's make x  the interest Juanita has to pay. The fraction would be x/600. If we have 7/100 interest, you would put that 7/100 = x/600. The next step is to cross multiply. That is 7 times 600 and 100 times x. You would get 4200 and 100x. In order to find x, you have to get rid of the 100, and to do that you have to divide both sides by 100. Remember, what you do to one side, do to the other. That leaves you with 4200/100 and 100x/100. The result is 42 and x, so x = 42. Juanita has to pay $42 interest.

A) 4

Answers

what you want to do here is plug 2 in for x. when a question asks you to evaluate a certain equation at a certain number, it's just asking you to plug the value in for your variable. i'm assuming that 12x + 8 is meant to be set over 4 as a fraction.

(12(2) + 8)/4 ... figure out the top first. 12*2 = 24, 24 + 8 = 32.

32/4 = 8, so your correct choice is D.
Final answer:

To evaluate the expression (12x + 8) / 4 for x = 2, you multiply 12 by 2, add 8, and then divide by 4. The final answer is 8, which corresponds to option D.

Explanation:

To evaluate the expression (12x + 8) / 4 for x = 2, you substitute the value of x into the expression and then simplify. First, multiply 12 by 2 to get 24, then add 8 to get 32. After that, divide 32 by 4 to get the final answer.

Here is the step-by-step calculation:

Substitute x with 2: (12*2 + 8) / 4.Multiply 12 by 2: (24 + 8) / 4.Add 24 and 8: 32 / 4.Divide 32 by 4: 8.

Answers

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

Answers

Final answer:

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.
