Given:
Diameter of outer circle = 20 inches.
We need to find the Area of the outer circle to get the radius of the inner circle.
Area = πr²
Outer circle Area = 3.14 * (10in)² = 314 in²
314 in² * 64% probability = 200.96 in² Area of the inner circle.
200.96 in² = 3.14 * r²
200.96 in² / 3.14 = r²
64 in² = r²
√64 in² = √r²
8 in = r
radius of inner circle is 8 inches.
The second option is your answer.
2(1) - 3 = 2 - 3 = - 1
2(2) - 3 = 4 - 3 = 1
2(3) - 3 = 6 - 3 = 3
2(4) - 3 = 8 - 3 = 5
- 1 + 1 + 3 + 5 = 8
Hi there! To find the total cost after the markup, all you have to do is multiply by 105% (1.05), because you’re incorporating the cost of jeans bought plus the markup. 50 * 1.05 is 52.5. The jeans costed $52.50 after the markup.
1. 130°
I don't remember too many specifics from my past math classes, but I always remembered this because that is an upside-down mirror of the 130° angle.
2. 50°
A straight line is 180°, and 180 - 130 = 50.
