Answer:
126.2 meters
Step-by-step explanation:
A trapezoid's area is found using the formula A = 1/2 (a+b)h where a and b are the two bases. Substitute A = 12,052.1, a = 82.4 and b=108.6. Then solve for h.
A = 0.5(a+b)h
12,052.1 = 0.5(82.4 + 108.6)*h
12,052.1 = 0.5(191)h
12,052.1 = 95.5h
126.2 = h
Answer:
392000
Step-by-step explanation:
8*10^4 = 80000
4*10^6= 4000000
4000000 - 80000 = 392000
131+108+107+110+x=540
456 + x = 540
-456 -456
x = 84
Answer:
30 gallons
Step-by-step explanation:
Let c represent the capacity of the container in gallons.
2/5c +8 = 2/3c . . . . adding 8 gallons to 2/5 full gives 2/3 full
8 = (2/3-2/5)c = 4/15c . . . . subtract 2/5c
8(15/4) = c = 30 . . . . . . . . . multiply by 15/4
The container can hold 30 gallons.
