Answer:
a., b., e.
4x10^6 would be 4,000,000 so d. isn't correct.
40^6 equals 4,069,000,000 so c. isn't correct either.

Answer:
1/4 mile
Step-by-step explanation:
A = length · width
let 'n' = length
1/8 = 1/2n
8n = 2
n = 2/8 or 1/4
Answer:
b
Step-by-step explanation:
area of triangle = 1/2 x c x d =cd/2
area of semicircle = 1/2 x π x r^2 = 1/2 x π x (a/2)^2 = 1/2 x π x a^2/4 =πa^2/8
area of shape = area of triangle + area of semicircle
X° +110° = 180* . . . . . "linear" angles
x = 70
x° +112° +y* +88° = 360° . . . . . sum of interior angles of a quadrilateral
y° +270° = 360°
y = 90
The values of the variables are
.. x = 70
.. y = 90
