[tex]\frac{7}{t}[/tex] is the answer to [tex]\frac{49t^2}{7t^3}[/tex]
Step-by-step explanation:
[tex]\frac{5s^2t^2}{40st }[/tex]
5 can go into 40 eight times.
[tex]\frac{s^2t^2}{8st}[/tex]
Since s and t are squared in the numerator and st isnt in the denominator, s and t can go into s squared and t squared.
[tex]\frac{st}{8}[/tex]
[tex]\frac{49t^2}{7t^3}[/tex]
7 can go into 49 seven times.
[tex]\frac{7t^2}{t^3}[/tex]
Since t is squared in the numerator and t is cubed in the denominator, t sqaured can go into t cubed.

On the scale model, the distance between the wheels on the left and the wheels on the right is inches. The state of Wyoming has old railroad tracks that are 4.5 feet apart. Can the modern train travel on those tracks?
Answers
Answer:
Step-by-step explanation:
No, modern train cannot travel on old railroad.
In rail transport, track gauge is the spacing of the rails on a railway track and is measured between the inner faces of the load-bearing rails.
Most of the modern train are based on broad gauge. The separation in broad gauge is about 5 ft and 6 inches and in the standard gauge the separation between the tracks is 4 ft and inches. So for the modern train it is not possible to travel on the tracks whose separation is no more than 4.5 feet.
Answer:
No, modern train cannot travel on old railroad.

I think I am right but it should be F/2 equals 4
Step-by-step explanation:
because you canceled out 9 so 9 is out of the equation
Answer:
f/2 = -20
f = -10
Step-by-step explanation:
1. Subtract 9 on both sides
f/2 + 9 -9 = 4 -9
= f/2 = -5
2. Multiply all terms by the same value to eliminate fraction denominators
2* f/2 = 2(-5)
3. Simplify
f = -10
Swim team members can race or dive. At a meet, 18 members race. The ratio of racers to divers is 6:2. How many meters are on the team? Show your work.
Plz help it due in 10 minutes.
Answers
Answer:
6 meters
Step-by-step explanation:
Set up a proportion as 18/x=6/2. The meters are unknown, so that's what the x value represents. Then, cross multiply (18 times 2 and 6 times x) to get 36=6x. By dividing both sides of the equation by 6, you'll get 6 meters as your answer.
