Since the problem is given all the total walking distance, the first thing we are going to do is find the total distance in the map:


Now that we have the distance in the map, we can establish a ratio between the walking distance and the distance in the map:

We can conclude that each inch the map represents 0.5 miles of walking distance.
It is 65 over 100. simplified is 13 over 20
After the last step, you have to plug x into the equations. 5(5)+8=33 and 8(5)-1=39. You do this because it asks you to find the measurements of the angles, meaning the whole thing, not just x. To check, you add the two values of EFG and EFH, and they should equal EFG. 33+39=72, so it all checks out!
Answer:
19. 1400 ft^2
20. 1680 + 112pi m^3
For 20, a decimal answer would be 2031.86
Step-by-step explanation:
19. Lateral surface area refers to the area without including any horizontal planes(the tops and the bottoms - hence the name lateral). The lateral surface area of this prism is simply 5 equivalent rectangles. Each rectangle has an area of 280(14*20). Thus, the answer is 280*5 = 1400 
20. The volume of a shape such as this(where the horizontal planes are always the same shape) can be calculated by the area of the base times the height. In this case, the area of the base is the semi circle (area of
). The area of the rectangle is 15 * 8 = 120. Adding these together gets you 120 + 8pi. Multiplying this by the height of 14 gets you 1680 + 112
36, |-12|=12 and |-3|= 3. Using inverse operations, we multiply instead of dividing and get 36.
