a contractor bought a rectangular piece of land that has a perimeter of 200 feet. the ration of the land's length to width is 9:
16
1 answer:
Answer:
length/width = 1/1 = 1
Step-by-step explanation:
(3x)(2x) = 12150
6x^2 = 12150
x^2 = 2025
x = 45
Length is 135 ft, width is 90 ft, perimeter is 450 ft
Geometric mean: 135 : x :: x : 90
x^2 = 12150
x = 45√6
The second rectangular piece of land is a square !

Answer:
-13
Step-by-step explanation:
-5x + 2 = 67
-5x = 65
5x = -65
x = -13
First divide bot sides of the formula by 1/2(3.14):-
2A / 3.14 = r^2
r = sqrt (2A/3.14)
Because it's a positive number that can be gained by multiplying two smaller positive numbers.
Won: 4/7 x 35 = 20
lost: 3/7 x 35 = 15
