Answer:

The number is 523

Step-by-step explanation:

The question is English is

Number 289 less than 812

Let

x ----> the number

To find out the number subtract 289 from 812

$812-289=523$

therefore

The number is 523

Answer:

213.333 ounces

Step-by-step explanation:

A small office purchases bottled drinking water. The water comes in containers that hold 5 gallons. Two-thirds of the office container was drained last week to put out a fire in the wastebasket.

a. How much water (in ounces) is left in the container?

b. How many 12-ounce glasses can be filled with the water that remains in the container

Container = 5 gallons

Two-thirds was drained last week to put out a fire in the wastebasket

That is 2/3 of 5

= 2/3 × 5

= 10 / 3 gallons

Water left in the container = 5 - 10/3

= 15-10/3

= 5/3 gallons

Convert 5/3 gallons to ounces

5/3 gallons = 213.333 ounces

B. Number of 12 ounces glass that can be filled from the water left in the container = 213.333 ounces / 12

= 17.77775

write an equation in point-slope form for the perpendicular bisector of the segment with endpoints at A(-2,2) and B(5,4)

dimaraw [331]

The equation in point-slope form for the perpendicular bisector of the segment with endpoints at A(-2,2) and B(5,4) is $y - 3 = \frac{-7x}{2}+ \frac{21}{4}$

<h3>Solution:</h3>

Given that we have to write equation in point-slope form for the perpendicular bisector of the segment with endpoints at A(-2,2) and B(5,4)

Let us first find the slope of given line AB

The slope "m" of the line is given as:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Here the given points are A(-2,2) and B(5,4)

$\text {Here } x_{1}=-2 ; y_{1}=2 ; x_{2}=5 ; y_{2}=4$

$m=\frac{4-2}{5-(-2)}=\frac{2}{7}$

Thus the slope of line with given points is $\frac{2}{7}$

We know that product of slopes of given line and slope of line perpendicular to given line is always -1

$\begin{array}{l}{\text {slope of given line } \times \text { slope of perpendicular bisector }=-1} \\\\ {\frac{2}{7} \times \text { slope of perpendicular bisector }=-1} \\ \\{\text {slope of perpendicular bisector }=\frac{-7}{2}}\end{array}$
