45 because 1set equals 3 push ups and she did ten sets so 10sets equal 30 push ups and then her coach asked her to do 15 more so 30 plus 15 equals 45 so she did 45 push ups that day!
The answer is c=50.272, for other problems like this use the formula: The circumference = π x the diameter of the circle (Pi multiplied by the diameter of the circle).
Because this is a triangle, all three angles put together equals 180 degrees.
We can add the angles together and set them equal to 180 to solve for the value of y.
y + y - 12 + 56 = 180
Combine like terms.
2y + 44 = 180
Subtract 44 from both sides.
2y = 136
Divide both sides by 2.
y = 68
<u>The value of y is equal to 68 degrees.</u>
Pizzas are circles. Area of circles is (pi)r^2.
Then find the cost per in.^2
Smallest cost per in.^2 is better buy.
