Answer:
it would take 16 minutes
Step-by-step explanation:
32,000 (height) ÷ 2000 (decent) = 16 (time it takes to land)
Answer:
B
Step-by-step explanation:
x² - 12x + 11 = 0 ( subtract 11 from both sides )
x² - 12x = - 11
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 6)x + 36 = - 11 + 36
(x - 6)² = 25 ( take square root of both sides )
x - 6 = ± 
= ± 5 ( add 6 to both sides )
x = 6 ± 5
Then
x = 6 - 5 = 1 ⇒ (1, 0 )
x = 6 + 5 = 11 ⇒ (11, 0 )

Considering the area of a rectangle, it is found that the area of Bob's remaining plot of land is of 12.5 acres.
<h3>What is the area of a rectangle?</h3>
The area of a rectangle of length l and width w is given by the multiplication of these dimensions, that is:
A = lw.
In this problem, both the length and the width are divided in half, hence the proportion remaining is given by:
A = 0.5l x 0.5w = 0.25lw = 25% of the initial area.
Hence:
0.25 x 50 = 12.5.
The area of Bob's remaining plot of land is of 12.5 acres.

Answer:
x=0
Step-by-step explanation:
2(3x - 1) + 2(4x + 5) = 8
Distribute
6x -2 +8x +10 =8
Combine like terms
14x +8 = 8
Subtract 8 from each side
14x+8-8=8-8
14x =0
Divide each side by 14
14x/14 = 0/14
x=0
