Answer:
Step-by-step explanation:
Since the tanks are congruent, they both have same volume.
If you rejoin them, it will form a cylinder with the radius of 15 ft and height of 120 ft.
<u>The volume of the cylinder:</u>
- V = πr²h = 3.14*15²*120 = 84780 ft³
<u>The volume of each tank is half the volume of the cylinder:</u>
- V(tank) = 84780 / 2 = 42390 ft³

Answer: and
x+(x-2)=7 cab be used to determine the value of x.
Step-by-step explanation:
Given,
Heidi has x donations.
Grandpa Case has 2 fewer donations than Heidi.
Fewer means subtraction.
Grandpa has = x - 2
They have 7 donations in all.
Heidi's donations + Grandpa's donations = Total donations
x+(x-2)=7
x+(x-2)=7 cab be used to determine the value of x.

A. Average of a data set.
Answer:
x = 88
Explanation:
2x + 14 = 190
Subtract 14 from both sides
2x + 14 − 14 = 190 − 14
2x = 176
Divide both sides by 2
2x / 2 = 176 / 2
x = 88
