Step-by-step explanation:

to fill it

Answer:

5 containers

Step-by-step explanation:

The area of each container is 200, so if you have 1,000 cubic centimeters of sand and you only use 200 for one container you could fill up 5 containers. 200 x 5 = 1,000

12(7n - 4) =12*7n - 12*4

               = 84n - 48

Answer:

I think the answer would be 4 to 5 packages.

Step-by-step explanation:

Answer:

R = sqrt 3 * (V /( pi * h))

V = 62.8

pi = 3.14

h = 15

now we sub

R = sqrt 3 * (62.8 / (3.14 * 15)

R = sqrt 3 * (62.6 / 47.1)

R = sqrt 3 * 1.33

R = sqrt 3.99

R = 1.9 rounds to 2 inches <===

Step-by-step explanation:

Answer: Cupon B ($22 rebate on $63 shoes)

Step-by-step explanation: Cupon A would equal $44.10 while Cupon B would equal $41

The question you posted seems incomplete. You posted the set up information, but the actual question itself is missing. I'm assuming you want to find which is the better deal? If my assumption is correct, then go ahead and read on. If my assumption is incorrect, then you can ignore this post.

---------------

Solution:

The percent 30% converts to 0.30 when we move the decimal point two spots to the left. Note how 30% = 30/100 = 0.30

So saying 30% of 63 means 0.30*63 = 18.90, which is the amount of money we save. This value is smaller than the $22 rebate amount so that means Coupon B is the better deal.

We can see that if we go with Coupon A, then the final price will be 63-18.90 = 44.10; if we go for Coupon B, then the final sale price is 63-22 = 41. This is further confirmation that choice B is better.

Be careful though: The $22 rebate means that you'll have to mail (or possibly email) some kind of proof of purchase form/card. A bit of time will pass by until you can get the $22 in the mail. Some companies probably offer some kind of direct deposit. A rebate is basically a partial refund that acts more or less like a discount, but it's not an immediate discount. In short, you will not save the $22 right away and instead you'll be expected to pay the full $63 for the shoes when you're at the checkout counter. So if you want to save money right away, then go for option A. However, I still think option B is the better choice in the long run. Of course, it will depend on how long you're willing to wait for that savings.

Answer:

The tile border around the kiddie pool is 72 square feet.

Step-by-step explanation:

To find the area of the tile border, you take the area of the entire rectangle (both inner and outer) and subtract the inner rectangle from it.

Area of entire rectangle: 18 * 9 = 162 ft^2

Area of inner rectangle: 15 * 6 = 90 ft^2

Area of tile border: 162 - 90 = 72 ft^2

The tile border around the kiddie pool is 72 square feet.

Answer:

A. 13

Step-by-step explanation:

When you plug the numbers in, 4 times 13 = 52+9=61 and 63 is still greate so anything above 13 would make the sentence correct. So that is why 13 is NOT a solution.

Answer:

A.13

Step-by-step explanation:

4x+9>63

-9 -9

4x >54

x=>13.5

Answer:

MULTIPLYING

Proper fractions: The first step when multiplying fractions is to multiply the two numerators.

Improper: The first step is to convert all the fractions into improper fraction.

Mixed: Multiply the numerators from each fraction to each other and place the product at the top.

DIVIDING

Proper: Dividing two fractions is the same as multiplying the first fraction by the reciprocal of the second fraction.

Improper: When you divide by a fraction, you want to cancel the second fraction by changing it to a 1

Mixed: To divide mixed fractions, you could first convert each to an improper fraction.

Step-by-step explanation:

:)

Answer:

Multiply

So, to multiply two mixed numbers, rewrite each as an improper fraction and then multiply as usual. Multiply numerators and multiply denominators and simplify. And, as before, when simplifying, if the answer comes out as an improper fraction, then convert the answer to a mixed number. Multiply.

Dividing

Change both mixed numbers to improper fractions. Invert the second improper fraction, then multiply it by the first fraction to get the answer. Reduce it if possible, and convert it to a mixed number if desired.
