A pillow that usually costs $18 is marked down 25%. Which expressions can be used to find the new price of the pillow?

Answers

Answer 1

Answer:

Answer:

x = 18-(0.25×18)

Step-by-step explanation:

The price of the pillow = $18.00

cost is marked down = 25% = $(25)/(100)$ = 0.25

Let the new price be x

The expression that can be used to find the new price of the pillow will be

x = 18-(0.25×18)

Answer 2

Answer:

n= new price

n=18-(18*0.25)

Amy had homework for math,science,and history.she spent 1/3 of her time working on math and 1/4 of her time working on science.

Answers

First we need to multiply to make the fractions have equal denominators so we can add/subtract.

math: 1/3 x 4/4=4/12
science: 1/4 x 3/3=3/12

Now we can find the time she spent on history (I assume this is what you are looking for)

Total time-math time-science time=history time
12/12-4/12-3/12
=5/12

Amy spent 5/12 of her time working on history.

So,

I will be assuming the same thing as the other user.

First, we have to convert the fractions so that they have common denominators.

$(1)/(3) * (4)/(4) = (4)/(12)$

$(1)/(4) * (3)/(3) = (3)/(12)$

Now we add the fractions together.

$(4)/(12) + (3)/(12) = (7)/(12)$

Now, to find the fraction of the time that Amy spent on history, we need to subtract the sum of the time she spent in math and science from one whole.

$(12)/(12)-(7)/(12)=(5)/(12)$

Amy spent 5/12 of her time working on history.

Estimate 2.436 divided by 12

Answers

Use a calculator!
Or if you must,
2.4 rounded down is 2.
12 divided by 2 is 6 so the answer would be less than but not greater than 6.

Final answer:

The estimation of 2.436 divided by 12 is approximately 0.203 .

Explanation:

The student wants to estimate the result of 2.436 divided by 12. The number 2.436 is closer to 2, therefore we can estimate it as 2. Now our division problem becomes 2.436 divided by 12. It would be less than 1 since 2 is smaller than 12. However, to get a more exact estimation, we could think of it as if every 1 of the 12 gets 1/6 of the 2, which means each one would get about 0.203. Therefore, 2 divided by 12 is approximately 0.203.

Choose 1 answer: (Choice A) Exactly 90 times (Choice B) Close to 90 times but probably not exactly 90 times (Choice C) Exactly 160 times (Choice D) Close to 160 times but probably not exactly 160 timesPLEASE GIVE EXPLANATION!!!

Answers

Answer:

Number of songs=360

p(classical songs)=4/9

best prediction=360*4/9=160

so they answer is 160.

When 40% of the girls left the school assembly, the ratio of the number of boys to girls became 3 to 4. If there were w girls when the assembly started, what was the total number of boys when the assembly started?

Answers

I am pretty sure the answer is 15 boys at the beginning of the assembly.
That would mean that there were 28 girls there, and if 40% of them left, which would mean that 8 left, leaving 20 girls. This would leave the assembly with a 3:4 ratio of boys to girls.

There were 15 boys at the beginning of the assembly and 28 girls
