Use the Distributive Property to find the price of 9 CDs that cost $13.99 each.

Answers

Answer 1
Answer:

Answer:

The cost of 9 CD's is $125.91.

Step-by-step explanation:

The distributive property can be described as:

a(b+c)=ab+ac

Here given is that the cost of 1 CD is $13.99

We can write this cost as = 13+0.99

And the cost of 9 CD's can be calculated as:

9(13+0.99)

Further solving this we get

(9*13)+(9*0.99)

= 117+8.91=125.91 dollars

Therefore, the cost of 9 CD's is $125.91.
Answer 2
Answer: To use the distributive property, we "distribute" a value on the outside of a set of parentheses to all of the values on the inside of the parentheses. For example...

6(3 + 9) = 6*3 + 6*9

For your problem, you only have one value 13.99, but we can split it apart to make it a little easier to work with (like with mental math).  We can say that 13.99 is the same as 10 + 3.99.  Now we can take it and multiply by 9 with the distributive property...

9(10 + 3.99) =
9*10 + 9*3.99 =
90 + 35.91 =

$125.91

no, you did the distributed property wrong

You are planning for a breakfast party and need enough milk for 20 people. Each person will drink about 200mL of milk. Which us the bat estimate of the amount of the milk you should prepare: 400mL or 4L?Explain.

Answers

1 liter = 1000 ml 
 so  4L is the amount of the milk you should prepare
You won't get 400mL because you are giving it to 20 people, and 400 mL would only give enough for 2 people. So 4L.

The prism has a surface area of 1312 mm2.What would the surface area of the prism be if each dimension were halved?


mm2

Prism with a length of thirty-two millimeters, a width of ten millimeters, and a height eight millimeters

Answers

Surface Area = 2(lw + lh + wh)

Divide each dimension by half, and then plug it in to the formula.

32/2 = 18
10/2 = 5
8/2 = 4

Surface Area = 2((4)(5) + (4)(18) + (5)(18))
SA = 2(20 + 72 + 90)
SA = 2(182)

SA = 364

The surface area if each dimension was halved would be 364 mm^2.
