Answer:
16 and 8
Step-by-step explanation:
Lets go ahead and calculate the area of each side; added together, this will give us the full surface area. First the base, which is 9 by 9 and a square. This means its area is 9*9, which equals 81. Next the triangles, which are all the same, so we only have to do it once and then add it 4 times at the end. The area of a triangle is (1/2)bh, so (1/2)(9)(7) = 31.5.
Finally, we just need to add the areas up.
81 + 31.5 + 31.5 + 31.5 + 31.5 = 81 + 4(31.5)
81 + 126 = 207 units^2
Answer:
a) Speed of the cyclist is (2.75/0.4) = <u>6.875 miles per hour</u>.
b) It will take (5.5/6.875) = <u>0.8 hours</u> to travel 5.5 miles at this rate.
- Remember: Speed=Distance/Time
