Answer:

Step-by-step explanation:

I think the attached phôt below is your full question.

And here is my answer:

Surface area of a triangular prism = hight * area of the base

Here we have:

h= 12
Area of the base = 1/2 *2* 1.5 = 1.5

=> Surface area = 12*1.5 = 18

18. Make the values have the same denominators.

4 2/3(8/8)= 112/24
5 3/8 (3/3)= 129/24

Add the values

112/24+129/24= 241/24

Simplify the answer

241/24= 10 1/24

dalvyx [7]

Answer:

Terrance will need a mortgage loan of US$ 174,250

Step-by-step explanation:

1. Let's review the information given to solve the question.

Value of the house Terrance Jacobs is going to buy = US$ 205,000

Down payment Terrance can afford = 15% of the value of the house

Down payment Terrance can afford = 15% of US$ 205,000

Down payment Terrance can afford = 15% * 205,000

Down payment Terrance can afford = US$ 30,750

2. For finding the amount of the mortgage loan Terrance need for buying the house, we should do this:

Amount of mortgage loan = Value of the house - Down payment

Amount of mortgage loan = 205,000 - 30,750

Amount of mortgage loan = US$ 174,250

Terrance will need a mortgage loan of US$ 174,250

Explain how you can use base 10 blocks to find 2.16÷3

Vikentia [17]

You can use 10 blocks by having 1 ten and 6 ones and then divide it into groups of 3 when you do that you are kind of subtracting when you take away 3 away each time. After that you multiply it, so you think of whatever times 3 is 16 which is 15 r1. Then your answer should be 30.
