Yes is equivalent because 12 x 4 is 48 and 5x5 is 25
To find the circumference of a circle you can use either of these equations
3.14 X Diameter or 2 X 3.14 X Radius. But in this case we will use the first one. So 3.14 X 14 = 47.6 so the circumference of this circle would be 47.6 inches.
I hope this helps :)
The two horizontal lines are parallel.
This makes the 80 degree angle and the angle ox x and 20 degrees are alternate interior angles and are the same.
This means x + 20 needs to equal 80.
X = 80-20 = 60 degrees.
Mary worked 22 hours.
To solve first you would subtract the amount she made in tips from her total earnings (317-185)
= 132
Then you divide that answer by her hourly salary of $6 (132/6)
