Answer:
40 and 10
Step-by-step explanation:
if you add them you get 50 and if you subtract them you get 30
First you would take 20% off the orignal price giving you 30.4$ after that you take 10% of 30.4 to get 27.36$.
Answer:
2.5 pi
Step-by-step explanation:

If you were trying to get the area of a whole circle, you would use
Area = pi r^2
You have to modify the formula to show that just part of the circle has an area that you are interested in.
The new formula is
Area = (theta/360) pi r^2
Givens
r = 30 cm
theta = 100
Solution
Area = (100 / 360) * pi * r^2 Substitute the givens into this formula
Area = (5 / 18) * pi * 3^2 Expand
Area = (5 / 18) * pi * 9 Cancel 9 into 18
Area = 5/2 * pi
Area = 2.5 * pi
1/49=x^2 where x is the side of the square
1/49=(1/7)^2, so the side length of the square is 1/7
Answer: 871.72 + (0.3926........x 42)
Step-by-step explanation: 23.56 x 37= 871.72
23.56/60= 0.3926................... x 42
