Answer:
around 6.6 years
Step-by-step explanation:
41,500=14,000*.45*x
41,500=6,300*x
41,000/6,300=x
6.5873=x
6.6=x
hope this helps!
im not sure about the first one but im 100% about 2 and 3
2-A
3-D
Answer:
-1
Step-by-step explanation:
Plug in one to the equation to get (1)^3 - 2(1)^2, 1 to the power of anything is 1 so it boils down to 1-2, which is -1
Answer:
∠ 1 = 160°, ∠ 2 = 20°
Step-by-step explanation:
The 2 angles are adjacent and supplementary, thus
∠ 1 + ∠ 2 = 180°, substitute values
5x + x - 12 = 180, that is
6x - 12 = 180 ( add 12 to both sides )
6x = 192 ( divide both sides by 6 )
x = 32
Thus
∠ 1 = 5x = 5(32) = 160°
∠ 2 = x - 12 = 32 - 12 = 20°
Answer:
option A
9×10^4/2×10^2
Step-by-step explanation:
Given in the question,
length of dollar bill = 6
width of dollar bill = 3
area of dollar bill = L x W
= 6 x 3
= 18inches²
length of driveway = 30
width of driveway = 20
area of driveway = L x W
= 30 x 20
= 600 ft²
1 ft² = 144 inches²
600 ft² = 86400 inches²
Number of dollar bills that would cover Kenisha driveway = 86400 / 18
Which can also be written as
86400 = 9 x 10
18 = 2 x 10²
