Jan is draining her garden pond. The pond had 100 gallons of water, and she can drain it at 0.75 gallons per minute. How long will it take before the pond has only 10 gallons left?

120 minutes.

Step-by-step explanation: it says before it only has 10 gallons left. Subtract to get 90 gallons before solving. 90/0.75=120. It will take her 120 minutes to have 10 gallons left after draining 90 gallons.

it would open into a square depending on the type of envelope i’m not sure about the second part

the above table 1 will calculate the population size (n) after a certain length of time (t). all you need to do is plug in the initial population number (no), the growth rate (r) and the length of time (t). the constant (e) is already entered into the equation. it stands for the base of the natural logarithms (approximately 2.71828). growth rate (r) and time (t) must be expressed in the same unit of time, such as years, days, hours or minutes. for humans, population growth rate is based on one year. if a population of people grew from 1000 to 1040 in one year, then the percent increase or annual growth rate is 40/1000 x 100 = 4 percent.
