Let width of the floor be x feet, them area is
x(x+2) = 168
x^2 + 2x - 168 = 0
(x - 12)(x + 14) - 0
so x = 12
the floor is 12 ft by 10 ft
the width of the rug should be 10 - 2(2) = 6 feet
Answer:
71°
Step-by-step explanation:
The angle of elevation of the hill can be obtiaed using trigonometry :
Given
the opposite length = 14.5 feets
Adjacent = 5 feets
The angle of elevation vabnbe obtained using :
Tan θ = opposite / Adjacent
Where θ = angle of elevation
Tan θ = 14.5 / 5
Tan θ = 2.9
θ = tan^-1(2.9)
θ = 70.97 = 71°
Answer:
400/1000×100%
40% is the percent of decrease from 1,000 to 400.
Six more than: 6 + or + 6
twice a number: let n represent the unknown number: 2n
6 + 2n = 16
So, the answer is either c or d
So, solve the equation
Subtract 6 on both sides of the equation
2n=10
Divide by 2 on both sides of the equation
n=5
So, the answer is C
