Train A and Train B start off at the same point and are traveling in the same direction. It takes Train A 30 minutes to get to S

tation X, moving at 100 miles per hour. It takes Train B 100 minutes to get to Station Y, moving at 30 miles per hour. What is the difference in the distances to Station X and Station Y?

Answer:

No difference

Step-by-step explanation:

The given parameters are;

The point Train A starts off = The point Train B starts off

The direction of travel of Train A = The direction of travel of Train B

The time it takes Train A to get to Station X, t₁ = 30 minutes = 0.5 hour

The speed of Train A, v₁ = 100 miles per hour

The time it takes Train B to get to Station Y, t₂ = 100 minutes = (5/3) hours

The speed of Train B, v₂ = 30 miles per hour

The distance from the starting point to Station X, d₁, is given as follows;

v₁ = d₁/t₁

∴ d₁ = v₁ × t₁

By substituting the known values, we have;

d₁ = 100 mph × 0.5 h = 50 miles

The distance from the starting point to Station Y, d₂, is given as follows;

v₂ = d₂/t₂

∴ d₂ = v₂ × t₂

By substituting the known values, we have;

d₂ = 30 mph × (5/3) h = 50 miles

Therefore;

The difference in the distances to Station X and Station Y = d₁ - d₂

d₁ - d₂ = 50 miles - 50 miles = 0

∴ The difference in the distances to Station X and Station Y = 0 (No difference).

Can someone help me with this?​
Anna35 [415]

Answer:

Let 'a' be the first term, 'r' be the common ratio and 'n' be the number of terms

Series = 2+6+18.......= 2+2•3¹+ 2•3².......= 728

Now,

Sum =  \frac{a( {r}^{n} - 1) }{(r - 1)}   \\

So,

\frac{a( {r}^{n} - 1)}{(r - 1)}  = 728 \\  \frac{2( {3}^{n} - 1) }{(3 - 1)}  = 728 \\  \frac{2( {3}^{n} - 1) }{2}  = 728 \\  {3}^{n}  - 1 = 728 \\ {3}^{n}=728+1\\ {3}^{n}  = 729 \\  {3}^{n}  =  {3}^{6}  \\ \boxed{ n = 6}

Therefore, number of terms is 6

  • 6 is the right answer.

What will happen to the size of the population in the long run?
Irina-Kira [14]
I'm assuming there's a chart, but if there isn't,

The population will continue to increase and decrease, as the population will grow until it's reached its carrying capacity, and then decrease because there aren't enough resources, and then increase, then decrease, etc.

Which expressions have exactly two factors? Choose ALL that apply.
marishachu [46]

Answer: The answer is F.

Step-by-step explanation: It’s F because the number would be multiplied equally because all of the number are multiplied by 2. The rest of them either have variables or variables with numbers in them, which looks kind of funky, so F is the answer. I hope you get it right :). Sorry, if I was late for the reply and if you already figured it out… :(.

2.) Use the Slope Intercept Form of a line to find the equation of the line from point C to point D.
mezya [45]

First we need slope

  • C=(0,0)
  • D(7,12)

\\ \sf\longmapsto m=\dfrac{12-0}{7-0}

\\ \sf\longmapsto m=\dfrac{12}{7}

Put D co-ordinates on y=mx+b

\\ \sf\longmapsto 12=\dfrac{12}{7}(7)+b

\\ \sf\longmapsto 12=12+b

\\ \sf\longmapsto b=12-12

\\ \sf\longmapsto b=0

Now

slope intercept form.

\\ \sf\longmapsto y=\dfrac{12}{7}x

  • As b=0
