The formula for determining how long a hike will take is t=1/2(d+h) , where d is the distance in miles and h is the elevation gain in thousands of feet. solve for h. a. h=2d-t b. h=1/2t-d c. h=2t-d d. h=(t-d)/2

Consider a cube that has sides of length l. now consider putting the largest sphere you can inside this cube without any point on the sphere lying outside of the cube. the volume ratio -volume of the sphere/ volume of the cube is 1. 5.2 × 10−1 2. 3.8 × 10−1 3. 1.9 4. 2.5 × 10−1 5. 3.8
