Answer:

Hi!

The answer is 274.4 gallons of water remain to be used.

Step-by-step explanation:

You can use the Rule of three to solve this problem.

     100% ----> 280 gallons <em> // If 100% is 280 gallons</em>

     2% ----> x gallons <em> // then 2% would be x gallons.</em>

Now, multiply 2% by 280 gallons and divide the result by 100%:

x = \frac{2\% * 280 gallons}{100\%}  <em>// % divided by % is 1.</em>

x = 5.6 gallons losted as steam.

To calculate the gallons remain to be used:

280 gallons - 5.6 gallons = 274.4 gallons.

274.4 gallons are remaining. You would need to find how many gallons of water was lost as steam. You would do 280*0.02, which is 5.6 gallons. Then, subtract 5.6 from 280, and you get 274.4

const2013 [10]
A number is divisible by 3 if the sum of the digits of the number is divisible by 3.This statement is a conditional statement. However, it is not in its standard form. A conditional statement is known as an If-then statement.

It should be written as:

If the sum of the digits of the number is divisible by 3 then a number is divisible by 3.

There are two parts of a conditional statement. The first part is the hypothesis, the second part is the conclusion. The hypothesis starts with "if". The conclusion starts with "then".

The conclusion of the conditional statement is THEN A NUMBER IS DIVISIBLE BY 3.

Is it possible for a system to have more than one solution? Explain your answer
Anastasy [175]
A linear system can have infinite solutions if both systems represent the same line. if a linear system down not represent the same line then it can only have one or no solutions. No solution is if the system is representing parallel lines and one solution represents an intersection of the two lines.  in a nonlinear system you can have infinite or up to a maximum of intersections as the highest degree of the systems.
