11 cubic feet is the answer
20 divided by 40=2
20x40=800
800 divided by 40= 20
Well it depends what 'v' stands for
well all you need to do is replace the v with the number it stands for. For example if v=2 then the expression would be 4.2(2) - 5 - 6.5(2)
Then you use the order of operations. first you multiply
8.4 - 5 - 13
then you subtract from left to right
8.4 - 5 = 3.4
3.4 - 13 = -13 - 3.4 = -9.4
So IF v=2 (I used 2 as an example, V might not = 2 in your case) then the
answer will be -9.4
I hope this helped you :3
...just write the angles that are congruent...And it says this is middle school,but this is elementary school problems...
#30 and #31 are in y = mx + b. m = slope, and b = y-intercept.
30. slope = 2/3 y-intercept = 1
31. Slope = -9/5 y-intercept = -4
To make the x's get on the right side of the equal sign, subtract it on both sides.
32. 6x - y = -2
32. 6x - y - 6x = -2 - 6x
32. y = 6x - 2
