Answer:

The slope of line r and s is $(k-n)/(j-m)$ .

Step-by-step explanation:

We are given the lines PQ and P'Q' represented by r and s.

The slope of a line having end points $(x_(1),y_(1))$ and $(x_(2),y_{})$ is given by $(y_(2)-y_(1))/(x_(2)-x_(1))$ .

B. Slope of line r.

Since, the line r have end points ( m,n ) and ( j,k ).

Slope = $(k-n)/(j-m)$ .

C. Slope of line s.

Since, the line r have end points ( m,n+e ) and ( j,k+e ).

Slope = $(k+e-(n+e))/(j-m)$

i.e. Slope = $(k+e-n-e)/(j-m)$

i.e. Slope = $(k-n)/(j-m)$

Hence, the slope of line r and s is $(k-n)/(j-m)$ .

Step-by-step explanation:

There are a total of 100 balloons. If the ratio of yellow balloons to blue balloons is 8 to 12, how many of them are yellow

Answers

If you have 8 yellow balloons for every 12 blue balloons, then if you have 20 balloons in total, 8 out of 20 of those balloons will be yellow. Then you can set up this ratio:

$(8yellow)/(20total) = (Xyellow)/(100total)$

Then, you can use either cross multiplication or multiply the numerator and denominator by the same number to help solve for x. Personally, I prefer cross multiplication, so that's what I'll show you here:

$(8yellow)/(20total) = (Xyellow)/(100total) \n 8yellow*100total=20total*Xyellow$

Finally, solve for x:

$8yellow*100total=20total*Xyellow \n 8*100=20*x \n 800=20x \n 800/20=20x/20 \n x=40yellow$

If you had 100 balloons, you will have 40 yellow balloons.

Hope this helps!!

Step-by-step explanation:

The area of a rectangular field is 7007

yd2
. If the width of the field is
77
yards, what is its length?

Answers

The answer is 91
Length times width equals the area

area is length multiplied by width
if you have the area and the width you must divide so you can find the length
7007=77 times x
to find x divide by 77
x=91 so the length is 91
