Together they paint 60 feet in an hour. 30 in half an hour.
60 + 60 + 30 = 150.
So it takes two and a half hour.
Area of shaded part = area of circle - area of the square
= pi (6)^2 - area of the square.
Area of square = (m of one side) ^2
measure of of side is found as follows:-
6^2 = 2s^2 where m of the side = 2s
s = sqrt 18 so side of square = 2 sqrt18
area of square = (2 sqrt18)^2 = 4*18 = 72
area of shaded region = 36pi - 72 = 41.1 sq units to neraest tenth
Answer:
x = 6y
Step-by-step explanation:
x = 3z and z=2y
Substitute the second equation into the first
x = 3 (2y)
x = 6y
Answer:
(-7, 1)
Step-by-step explanation:
Coordinate rules :]
Reflection over x-axis -- (x, y) -> (x, -y)
Reflection over y-axis -- (x, y) -> (-x, y)
Reflection over y = x -- (x, y) -> (y, x)
Reflection over y = -x -- (x, y) -> (-y, -x)
