Answer:

Step-by-step explanation:

1) y = 50x + 2500

2) y = 200x + 1000

if we build a system with the two equations, we have:

50x+2500 = 200x + 1000

150x = 1500

x = 10

y = 2000 + 1000 = 3000

3) 10

4) $3000

A Tourist Information Center is between a Bus Station and a Train Station. When mapped on a grid, the Tourist Information Center

deff fn [24]

Given :

The Tourist Information Center is located at (11,0) and the Bus Station is located at (-1,-10).

Also , Tourist Information Center is between a Bus Station and a Train Station.

To Find :

The point of location of train station .

Solution :

Let , point of location of train station is ( x,y ).

We know , mid-point of two points ( a, b) and ( c, d ) is given by :

$(\dfrac{a+c}{2},\dfrac{b+d}{2})$ .

Since , Tourist Information Center is between a Bus Station and a Train Station.

So , it is given by :

$( 11 , 0 ) = (\dfrac{-1+x}{2},\dfrac{-10+y}{2})$

Comparing both coordinate :

$\dfrac{x-1}{2}=11\\\\x=22+1\\\\x=23$

and

$\dfrac{y-10}{2}=0\\\\y=10$

Therefore , Train Station is located at point ( 23 , 10 ) .

Hence , this is the required solution .

Sever21 [200]

Answer:

Ethan rollerbladed each day $\frac{623}{d}$ kilometers.

Step-by-step explanation:

Given:

Ethan rollerbladed a total of 623 km over d days.

Now, to find the kilometers Ethan rollerblade each day.

Total number of distance rollerbladed = 623 km.

Total number of days = $d.$

<u><em>As, Ethan rollerbladed each day the same distance.</em></u>

Now, to get the distance Ethan rollerbladed in each day we divide total number of distance rollerbladed by total number of days:

$Ethan\ rollerbladed\ each\ day\ =\ \frac{Total\ number\ of\ distance\ rollerbladed}{Total\ number\ of\ days}$

$Ethan\ rollerbladed\ each\ day\ =\ \frac{623}{d}$

Therefore, Ethan rollerbladed each day $\frac{623}{d}$ kilometers.

The masses of four planets in a solar system outside the Milky Way are given below.

zhenek [66]

Your answer is Planet B, Planet D, Planet A, Planet C.
Look at the exponents.
23 comes before 24 and 27. So 3.30 x 10 ^ 23 comes first. Next, 24, and there are 2, so go by the decimals, 4.87 comes before 5.97. So 4.87 x 10^24 comes before 5.97 x 10^24. Then, that leaves 1.89 x 10^27.

51.25 per month which is $615 per year

They save 5 per month if they pay full year

(51.25-5)= 46.25 per month is $555

so it costs $555 if they pay all at once.
