Answer:

The tree is 45 meters high.

Step-by-step explanation:

Drawing this out will make it much easier.

In the figure, 3 is proportional to 27, and 5 is proportional to the missing side (x).

Insert the figures into an equation and solve:

3/5 *  27/x

Cross multiply:

3(x)= 27(5)

3x=135

135/3=x

x=45

A CD player is on sale for $90 at an electronics store. If the original price was $125, what was the percent of discount
krek1111 [17]
This is the working of how it is 28% discount

Find the amount of discount : $125 - $90 = $35
Divide by the original price : $35/125 = 0.28
Change in to percentage : 0.28 x 100 = 28%

Therefore the percentage discount is 28% off

Consider the line y=9x-1.
OLEGan [10]

Step-by-step explanation:

Slope=9

i)

y−y1=m(x−x1)

When line is parallel

y+5=9(x-6)

y+5 = 9x - 54

<h3>59 = 9x-y </h3>

When line is perpendicular

y+5=-1/9(x-6)

9(y+5)= -1(x-6)

9y + 45 = -x+6

<h3>x+9y = -39</h3>
