Answer:
V = 112
Step-by-step explanation:
Volume = Area of the base x height, so area of the triangle is 1/2(8)(4) = 16
Volume = 16 x 7 = 112
Answer:
15. y = 6x
16. x = 11
Step-by-step explanation:
15. A direct variation equation is of the form ...
y = kx
Solving for k, we find ...
k = y/x = 42/7 = 6
The equation is y = 6x.
__
16. Filling in the given values, we have ...
66 = 6x
11 = x . . . . . . . divide by 6
Answer:
<u>D</u><u>.</u><u> </u><u> </u><u> </u><u>-</u><u>1</u><u>2</u><u>.</u><u>9</u>
Step-by-step explanation:
when you let x=7.1
-7.1+(-5.8) Adding a negative is the same as subtracting.
-7.1-5.8=<u> -12.9</u>
Answer: 198 ft^2
total Area = Area of rectangle + area of trapzoid
= base*height + .5(b1+b2)*height
9*18+.5(9+3)6
162+36
198
