Answer:

33 gallons of water to begin with.
Step-by-step explanation:
So we essentially are given two coordinates: (6,87) and (21,222). To find an equation, we simply need to find the slope and y-intercept. We know it's a linear equation because it's a steady stream, meaning a constant slope.
The slope is:

So, the rate at which the stream flows is 9 gallons per minute.
Now, let's find the initial amount of water. To do this, we can use point-slope form. Pick either of the two points. I'm going to use (6,87).

So, there were 33 gallons of water in the tank to begin with.
Answer: 400
Step-by-step explanation: cube root 8000 then that times itself
Answer:
expanded it would be 0.05 x 50 + 0.05 x 40
Step-by-step explanation:
4^3
Write 4 (3 times) because of the exponent.
4*4*4
= 16*4
= 64
Answer: 64
