Answer:

6 units

Step-by-step explanation:

Given: Triangle L N P has centroid S.

NS=7x-3, SR=5x-3

To find: NS

Solution:

Centroid is the point of intersection of the medians of the triangle such that it divides each of the median in ratio 2:1

So,

NS:SR=2:1\\\frac{NS}{SR}=\frac{2}{1}  \\

Put NS=7x-3, SR=5x-3

\frac{7x-3}{5x-3}=\frac{2}{1}\\  7x-3=10x-6\\10x-7x=-3+6\\3x=3\\x=1

Therefore,

NS=7x-3=7(1)-3=4\,\,units\\SR=5x-3=5(1)-3=2\,units

So,

NS=NS+SR=4+2=6\,\,units

The plate is rotated 90° about the origin in the counterclockwise direction. In the rotated trapezoid, what are the coordinates
Crazy boy [7]

You haven't provided the coordinates of the original trapezium, therefore, I can only help with the concept.

From the givens, we can know that the rotation was 90° counter-clockwise about the origin.

<u>The rule for this rotation is:</u>

(x , y) ..............> (-y , x)

This means that to get the points of the rotated image, negate the y-value then exchange it with the x-value

<u>Examples:</u>

(1 , 3) rotated 90° counter-clockwise about the origin will give (-3 , 1)

(-2 , 4) rotated 90° counter-clockwise about the origin will give (-4 , -2)

(1 , -2) rotated 90° counter-clockwise about the origin will give (2 , 1)

(-3 , -5) rotated 90° counter-clockwise about the origin will give (5 , -3)

Hope this helps :)

A bus​ averages 8 miles per hour faster than a trolley. If the bus travels 60 miles in the same time it takes the trolley​ to tr
hammer [34]

Answer:

Bus speed:  22 mph; Trolley speed:  14 mph

Step-by-step explanation:

Let rb represent the speed of the bus and rt the speed of the trolley.  Then rb = rt + 8 (mph).

Recall that distance = rate times time.  Two different distances and two different speeds are involved here, but only one time.

Thus,

             60 mi                                                           44 mi

     --------------------- = time (same in both cases) = -------------

          rt + 8 mi/hr                                                        rt

Cross-multiplying, we get   44rt + 8(44) = 60 rt, or

                                                    352 = 16rt.

Solving this for rt, we get    rt = speed of bus = 352/16 = 22 mph

The speed at which the bus travels is 22 mph and that at which the trolley travels is (22 mph - 8 mph) = 14 mph
