Hello!
To find the Volume, you'll need to multiply all of the measurements together. So you'll need to multiply 12, 16, and 13 together to get the Volume. First, let's multiply 12 and 16 together to get 192
192*13
Now you're left with 192*13. After you've multiplied them together you should get 2496
You should now have a Volume of 2496in³
I hope this helps!
Answer:
D.7
Step-by-step explanation:

Marked up by 135% means
new price=original price+(original price times markup) =125+(125 times 1.35)=293.75
tax
293.75 times 0.075=22.03125
293.75-22.03125=271.718 so aprox $271.72
selling price would be $271.72
Answer:
Rate = 6.56%
Step-by-step explanation:
Principal (P) = $5000
Interest (I) = $6312
Time (T) = 4 years
Rate (r) = ?
This question is involves simple interest and with the formula, we can easily plug in the values to find the rate.
S.I = P(1 + rt)
S.I = simple interest
P = principal
R = Rate
T = Time
6312 = 5000(1 + r*4)
6312 = 5000 + 5000*4r
6312 - 5000 = 20000r
1312 = 20000r
r = 1312 / 20000
r = 0.0656
Rate are calculated in percentage hence we'll multiply it by 100
R = 6.56%
Answer:
Hi, your answer is y=
-3
Step-by-step explanation:
We will use the slope-intercept formula which is

We will use two points in this case I'll use
(-2,-2) and (-8,1)
=
which can be simplified as 
Your Y will be -3
which your final answer will be y=-1/2x-3
Hope this helps :)
