6. 40 minutes (15/3 = 5 minutes/mile) - 5*8 = 40 min
7. 15,840 ft / 5 = 3.168 ft
Answer:
The perimeter is 56mm
Step-by-step explanation:
N/B: the figure is not given, nevertheless we can infer that the figure is a triangular figure given that the lengths provided is just three.
So the perimeter is the distance around the object.
Perimeter =20+20+16= 56mm
Answer The Answer is 80
Step-by-step explanation:
4*5=20
8*5=40
11*5=55
so 16*5=80
Answer:
11.59 centimeters
Step-by-step explanation:
Use the formula for the surface area of a rectangular prism: A = 2(wl + hl + hw)
Plug in the surface area, length, and width. Then, solve for h:
A = 2(wl + hl + hw)
467 = 2((4)(12) + h(12) + h(4))
467 = 2(48 + 12h + 4h)
467 = 2(48 + 16h)
467 = 96 + 32h
371 = 32h
11.59 = h
So, the height of the prism is approximately 11.59 centimeters
