Point E is located at (2, −3), and point F is located at (−2, −1). Find the y-value for the point that is 3 over 4 the distance
12345 [234]

The ratio of the two point is the coordinate at the plane where the two point are divided at the fixed amount of length. The<em> y</em> value of the point that is 3/4 distance from point E to point F is -1.5. thus the option 4 is the correct option.

Given information-

The coordinates of the point E is (2,-3).

the coordinates of the point F is (-2,-1).

As the 3/4 the distance from the point E is the point F is means the points which divides the line EF in the ratio of 3/1.

<h3>Ratio of two point</h3>

The ratio of the two point is the coordinate at the plane where the two point are divided at the fixed amount of length.

Suppose the ratio m:l are the ratio of the two points (x_1,y_1) and (x_2,y_2). Then the coordinate of the point which divide the line at this ratio can be given as,

(x,y)=\left ( \dfrac{mx_2+lx_1\tiems}{m+l} ,\dfrac{my_2+ly_1}{m+l}  \right )

Put the values,

(x,y)=\left ( \dfrac{3\times (-2)+1\times(2)}{3+1} ,\dfrac{3\times (-1)+1\times(-3)}{3+1}  \right )

(x,y)=(-1,-1.5)

Thus the<em> y</em> value of the point that is 3/4 distance from point E to point F is -1.5. thus the option 4 is the correct option.

Two groups collected litter along the side of the road it takes each group 5 minuites to clean up a 200 yard section how long do
meriva
This is dividing 
So 1 mile has 1760 yards so in total 
2 miles = 3520 yards and it takes 5 minutes to clean up 200 yards (We divide)
3520 ÷ 200 = 17.6 ( Now we multiply)
17.6 x 5 = 88 minutes or ( 1 hour and 22 minutes)

Three numbers are in the ratio 2:3:5. If the sum of their cubes is 1280.Find the three numbers.
Charra [1.4K]

Answer:256,384,640

Step-by-step explanation:

Take the ration sum 2x+3x+5x=1280

When we add we get 10x=1280

Then find x by. x=1280/10=128

Then substitute this x value to the ratios 2x=2*128 =256

3x=3*128=384

5x=5*128=640
