The answer is A
B and D are not answer as they show50-x=50
so x have to be 15 or 5 in A and C
but in C x=5 but 2×x+50 is nt equal to 70
so it is A
Answer:
Step-by-step explanation:
h = 5 ft
diameter = 2.4 ft
Radius is half of diameter
r = 2.4/2 = 1.2 ft
Now, find the volume of the tank
Volume = πr²h
= 3.14 * 1.2 *1.2 * 5
= 22.608 cubic ft
Time taken to fill the tank = Volume of tank ÷ volume of gas filled per minute
= 22.608 ÷ 2.3
= 9.8
= 10 minutes
Answer:
28.08 inches
Step-by-step explanation:

78% of 3 feet
= 78/100 x 3 feet
= 78/100 x 36 inches
= 28.08 inches
