Jayne will need to drive 40 mph on the way back.
Answer:
Step-by-step explanation:
Area of the figure = area of the down triangle + area of trapezium + area of the upper triangle
Down triangle:
Base b = 8 in
Height = 6 in

= 24 in²
Trapezium:
bases a = 4 in & b = 6 in
Height h = 5 in

= 25 in²
Area of the upper triangle:
Base b = 6 in
Height = (8 - 5) = 3 in

= 9 in²
Area of the figure = 24 + 25 + 9 = 58 in²
Mammals: If the number of Mammal exhibits is 25 and there are 75 total exhibits, the Mammal exhibits are 1/3 of the total exhibits at this Zoo. The ratio for 1/3 is 1:3, which is 25:75 in most complex form. That's 33.3 as a percentage, or 33.3%.
Reptiles: If the number of Reptile exhibits is 15 and there are 75 total exhibits, the reptile exhibits are 1/5 of the total exhibits here. The ratio for 1/5 is 1:5, which is 15:75 fully written out. This as a percentage is 20%.
