Begin by subtracting 1/8 from both sides to get

and get a common denominator of 8 on the right:

. Now simplify and cross-multiply: 39x = -16 andx = -16/39
Answer:
x = 1.5
Step-by-step explanation:
Since the axis of symmetry is between the 2 x intercepts, we can find it by finding the average of the x-coordinates of the 2 points.
(-7 + 10) / 2
3/2
= 1.5
So, the axis of symmetry is at x = 1.5
Since the figures are similar, we can establish a rule of three as follows.
We know that the area of the smaller figure is

, and its volume is

. We also know that the area of the larger figure is

; since we don't now its volume, lets represent it with

:



We can conclude that the volume of the larger figure is

; therefore, the correct answer is
a.
Answer:
625
Step-by-step explanation:
Cos 70 = horizontal distance /
100 horizontal distance = 100 cos 70 = 32.2feet
