Its D $160 because $135 times 25 percent is 33.75 and add that to 135
Answer:
a = 4, b = 8
Step-by-step explanation:
Rewrite 5b=6a+16 and 9a=7b-20 vertically:
5b=6a+16
9a=7b-20
Let's use substitution. Solve the first equation for b:
6a + 16
b = --------------
5
Substitute this result into the second equation:
9a = 7(b) + 16, or
6a + 16
9a = 7*-------------- - 20
5
Eliminate the fraction by multiplying all three terms by 5:
45a = 7(6a + 16) - 100, or
3a = 112 - 100, or:
3a = 12, which leads to a = 4.
Find b by subbing 4 for a in either of the given equations:
5b = 6(4) + 16, or
5b = 40, leading to b = 8
The solution is a = 4, b = 8

Step-by-step explanation:
Answer:
1696.460033 u^3
Step-by-step explanation:
1. The volume formula for a cylinder is
.
2. The radius is half of the width, So r would be 6. (12/2=6)
3. (6)^2 is 36. (6x6)
4. The height is given, which is 15.
5. Plug these numbers into the equation. It should be

6. This gives you your answer of 1696.460033 u^3.
