Your answer would be <span><span><span><span>5−7</span>+6</span>−3</span>−1</span>−<span>(<span>−8</span>) = 8</span>
11-a is false, because 10/28 can only be reduced to 5/14. 11-b is false, because 6/12 can be reduced to 1/2 ( 1/2 and 2/4 are equal though, but are not both in simplest form ) Finally, 11-c is true, 2/14 can be reduced to 1/7.
I believe the answer you are looking for is -9<span />
1) Solve for radius
Radius = r
2) Solve for height
Height = h
3) in calculator enter : ( 2 x 3.14 x radius squared ) + ( 2 x 3.13 x radius x height )
1/2 chance per flip
1/2 times 4 is 1/8
its 1/8 chance or 12.5%
