The town of West is 10 miles to the west of Center town while the town of East is 10 miles to the East of Centretown. One sunny

day, as shown in the diagram below:
A green car starts to drive down towards the town of East at the speed of 2 miles per minute.
At the same time. a red car also starts to drive down towards the town of East at a speed of 1 mile per minute.
Coincidentally, at the very same time a blue car leaves the town of East to travel towards the Center town at a speed of ½ mile per minute.

Answer:

d = 2t

d = t

d = 0.5t

Step-by-step explanation:

For an object in motion at constant velocity, the distance covered by the object in a time t is given by:

d=vt

where

d is the distance

v is the speed

t is the time

The distance is the total length of the path covered by the object in motion, regardless of its direction, so here we only care about the distance covered by each car, not about its direction.

The green car travels with a speed of

v = 2 mi/min

So the distance it covers is

d=2t

where t is in minutes while d is in miles.

Similarly, the speed of the red car is

v=1 mi/min

So its distance covered is

d=1t

Finally, the speed of the blue car is

v = 0.5 mi/min

So its distance is

d=0.5t

An investor has an account with stock from two different companies. Last year, her stock in Company A was worth $2690 and her st
Mrac [35]

Answer:

<h2> 14.7 %</h2>

Step-by-step explanation:

let us total the amount in her portfolio

Company A was worth $2690

Company B was worth $2980.

Total = $5670

when The stock in Company A decreases by 20%  she will have

$2690 *0.8=  $2152

Company A will worth $2152

when The stock in Company B decreases by 10%  she will have

$2980 *0.9=  $2682

Company A will worth  $2682

In all after the decline in are portfolio is $2152+$2682= $4834

the difference for the original amount in her investment is = $5670-$4834

= $836

The total percentage decrease in the investor's stock account

= (836/5670)*100= 0.147*100= 14.7 %

Z is centroid of triangle RST. What is RW, if RV=4x+3, WS=5x-1, and VT=2x+9?
vaieri [72.5K]
Given that Z is the centroid of a triangle RST. This means that Z is the point of intersection of the three medians of the triangle.

So,W is the midpoint of RSV is the midpoint of RTWe are given that:RV = 4x + 3 and VT = 2x + 9

Since V is the midpoint, then:RV = VT4x + 3 = 2x + 94x - 2x = 9 - 32x = 6x = 3

Now put the value of x in WS = 5x-1WS = 5x-1WS = 5(3) - 1 WS = 15 - 1 = 14WS = 14

Since W is the midpoint of RS, therefore RW = WSand WS = 14Therefore:
RW = 14
