Answer:

Yes, it is a rational number.

Step-by-step explanation:

A rational number is <u>a number that can be expressed in fractional form</u>. A rational number consists of:

Integers - they can be expressed in form of $\displaystyle{\dfrac{a}{1}}$ where a is an integer.

Fractions - obviously that they are in fractional form.
Repeating Decimals - they can be expressed in form of fractions as well.

Since the difference of 18 and 3 is 15 and the number 15 can be expressed as 15/1. Therefore, 15 or the difference of 18 and 3 is a rational number.

Sav [38]

Answer: The answer is 300 gallons.

Step-by-step explanation: Riemann sum is a method of calculating the total area under a curve on a graph, which is also known as Integral.

To calculate that area, we divide it into a number of rectangles with one point touching the curve. The curve has a closed interval [a,b] that can be subdivided into n subintervals, each having a width of Δ $x_{k}$ = $\frac{b-a}{n}$

If a function is defined on the closed interval [a,b] and $c_{k}$ is any point in [ $x_{k-1}$ , $x_{k}$ ], then a Riemann Sum is defined as ∑f( $c_{k}$ )Δ $x_{k}$ .
