Answer:Find the amount the store marked up the CDs by.
12.95 * .08 = 1.034 which rounds to 1.04
Add that to the former price.
12.95 + 1.04 = 13.99
Multiply by 4 to see how many 4 CDs cost.
13.99 * 4 = 55.96
Multiply by .1 to see how much the discount is.
55.96 * .1 = 5.596 which rounds to 5.60
Subtract the discount from the original price.
55.96 - 5.6 = 50.36
It costs $50.36 to buy four CDs this year.

Answer: Choice A
7(10+9) = 70 + 63
============================
Explanation:
when we multiply 7 by 19, we start off multiplying just 7*9 = 63 so just focus on the units or ones digit of 19 to have it multiply with 7. We have 63 as the result so we write down "3" as part of the answer, and carry the 6.
Then you move onto the tens digit. The tens digit of 19 is 1. Multiply 1 by 7 and we get 7, which adds on to the carry digit 6 to get 7+6 = 13. Therefore we'll stick a 13 in front of the 3 we got earlier to end up with the final answer 133
---------------
Using the distribution rule is much easier in my opinion
19 = 10+9
7*19 = 7*(10+9)
7*19 = 70+63
7*19 = 133
The idea is to multiply the outer 7 by each term inside the parenthesis
7*(10+9) = 7*10 + 7*9 = 70 + 63
So we multiplied the 7 by the 10 first to get 7*10 = 70
Then did the same for the 9 term as well 7*9 = 63
After those two multiplications, we add the results up: 70+63 = 133
What do you need help with?
The volume of the given figure is 210 cubic in..
We need to find the volume of the given figure.
<h3>What is volume?</h3>
Volume is a scalar quantity expressing the amount of three-dimensional space enclosed by a closed surface.
Divide the given figure into two convenient cuboids. That is one with dimensions length=4 in., breadth=2 in. and height=3 in. Another with length=4 in., breadth=4 in. and height=12 in.
We know that, the volume of cuboid =l×b×h cubic units.
Now, the volume of the cuboid=4×2×3=18 cubic in. and the volume of another
cuboid=4×4×12=192 cubic in.
The volume of the given figure=18+192=210 cubic in.
Therefore, the volume of the given figure is 210 cubic in.

Step-by-step explanation:
AB(x)/DE=BC/EF
AB/25=28/20
20AB=28×25
20AB=700
AB=700/20
AB=35
SO x=35
