Answer:
41/8
Step-by-step explanation:
6-6a=3a-3b+1, 9a-3b=5
<span>4b - 8 =3a, 3a-4b=-8
</span>
9a-3b=5
(3a-4b=-8 )*(-3 )
9a -3b= 5
-9a+12b=+24
adding both equations
9b=29, b=29/9
3a=4b-8=4*29/9 -8=(4*29-8*9)/9 = 44/9
a=44/27
a-b=44/27 - 29/9=44/27 - 29*3/27=-43/27
this is a correct answer, unfortunately they do not have this choice, probably they made mistake somewhere. I even check the solution of equations by substitution values of a and b into equations
Answer:
7. 4910.4
8. 3.6
Step-by-step explanation:
To find the volume of this prism, you first need to find the area of the triangular base. Since it is an equilateral triangle, the formula for its area is simply , which in this case is . Multiplying this by the height of 35, you get about 4910.4 cubic yards. For the cylinder, the formula for the volume is . Plugging in your known values, you get:
inches
Hope this helps!
