Set up the equation of two ratios:

3 racks 36 racks
----------- = --------------
15 min x

Solve this for x: 3x =540; x = 180 minutes, or 3 hours

For 1 rack of buns it takes 5 mins, Therefore you multiply both the number of buns and minutes it take to make 1 rack. 1*36 and 5*36.

Your answer would be 180 mins to make 36 racks of buns

On a number line, suppose the coordinate of A is 0 and AR=3. What are possible coordinates of the midpoint of AR?

Vika [28.1K]

Answer:

1.5 and -1.5

Step-by-step explanation:

The coordinate of A is 0. It is given that AR = 3. AR represents the distance from point A to point R. Remember that distance is always positive. So, from here we have two possibilities.

Point R is on Right side of A i.e. at coordinate 3
Point R is on Left side of A i.e. at coordinate -3

In both of these cases AR which is the distance from A to R will be 3.

So, if R is on Right side of A, the midpoint of AR would be:

$\frac{0+3}{2}=\frac{3}{2}=1.5$

Or if R is on Left side of A, the midpoint of AR would be:

$\frac{0+(-3)}{2}=\frac{0-3}{2}=-\frac{3}{2}=-1.5$

Thus, the possible coordinates of the midpoint of AR are 1.5 and -1.5

write an equation in slope intercept form of the line with the given characteristics: a) passes through (-3,0) and (-5,-3)

sweet [91]

The equation of the line in slope-intercept form is $\bf{y= \frac{3}{2} x + \frac{9}{4}}$ .

<h3>What is slope-intercept form?</h3>

y=mx +c, where m is the slope and c is the y-intercept

<h3>Steps</h3>

Find the slope
Substitute value of the slope into the equation
Substitute a pair of coordinates
Solve for c
Rewrite equation with value of m and c

<h3>Working</h3>

The first step is to calculate the slope of the line.

$\boxed{ slope = \frac{y _{1} - y_2 }{x_1 - x_2} }$

Slope

$= \frac{ - 3 - 0}{ - 5 -( - 3)}$

$= \frac{ - 3}{ - 5 + 3}$

$= \frac{ - 3}{ - 2}$

$= \frac{3}{2}$

Substitute the value of m into y= mx +c:

$y = \frac{3}{2} x + c$

Next, substitute a pair of coordinates that the line passes through. Here, I will substitute (-3, 0) into the equation.

When x= -3, y= 0,

$0 = \frac{3}{2} ( - 3) + c$

Find the value of c:

$0 = - \frac{9}{2} + c$

$c = \frac{9}{2}$

Substitute the value of c into the equation:

Thus, the equation of the line is $y = \frac{3}{2} x + \frac{9}{2}$ .
