It takes 5 minutes per square foot (400/180=5) and so 5 minutes per square for 720 squares: 720x5=3,600. 3,600 minutes is equivalent to 60 hours so it takes him 60 hours.
Answer: easy. The value is 3 tenths.

Answer:
B
Step-by-step explanation:
Answer:
The answer to your question is: 30°
Step-by-step explanation:
Data
m∠ 1 = 5x
m∠ 3 = x - 24
Process
m ∠ 1 = m ∠ 3 because they are vertical angles
5x = x - 24
5x - x = 24
4x = 24
x = 24 / 4
x = 6
Angle 1 = 5(6)
= 30°
Answer:
see explanation
Step-by-step explanation:
Given
2x + 7y = 42
To find the x- intercept let y = 0 in the equation and solve for x
2x + 7(0) = 42, that is
2x = 42 ( divide both sides by 2 )
x = 21 ← x- intercept or (21, 0 )
To find the y- intercept let x = 0 in the equation and solve for y
2(0) + 7y = 42 , that is
7y = 42 ( divide both sides by 7 )
y = 6 ← y- intercept or (0, 6 )
