\bf ~~~~~~~~~~~~\textit{middle point of 2 points }
\\\\
J(\stackrel{x_1}{-5}~,~\stackrel{y_1}{4})\qquad
K(\stackrel{x_2}{7}~,~\stackrel{y_2}{-10})
\qquad
\left(\cfrac{ x_2 + x_1}{2}~~~ ,~~~ \cfrac{ y_2 + y_1}{2} \right)
\\\\\\
\left( \cfrac{7-5}{2}~~,~~\cfrac{-10+4}{2} \right)\implies \left( \cfrac{2}{2}~~,~~\cfrac{-6}{2}\right)\implies (1,-3)

The water is flowing into the pool at 1.5 gallons per minute and it would take 20 minutes to be filled.

<h3>What is an Equation</h3>

An equation is used to show the relationship between two or more numbers and variables.

The pool holds 30 gallons of water. After 5 minutes, the pool is about one fourth full. Hence:

Time to full the pool = 5 minutes * 4 = 20 minutes

Rate of water flow = 30 gallons/20 minutes = 1.5 gallons per minute

The water is flowing into the pool at 1.5 gallons per minute and it would take 20 minutes to be filled.

Find the sum of all positive 3-digit numbers divisible by 12.
iren [92.7K]

First 3-digit number divisible by 12 is 108.

Last 3-digit number divisible by 12 is 996.

108 = 12 · 9

996 = 12 · 83

From 108 to 996 are 83 - 9 + 1 = 75 numbers divisible by 12.

108 is the first term of the arithmetic sequence.

996 is the 75th term of the arithmetic sequence.

Use the formula of a sum of terms of an arithmetic sequence:

S_n=\dfrac{a_1+a_n}{2}\cdot n

We have:

a_1=108,\ a_{75}=996,\ n=75

Substitute:

S_{75}=\dfrac{108+996}{2}\cdot75=(552)(75)=41,400

<h3>Answer: 41,400</h3>
