Answer:
1.36mph
Step-by-step explanation:
The escalator is moving at 2ft/s, lets convert this to miles/second.
2ft/s = 0.000378788miles/s.
Now that we have the miles/second lets multiply this value by 3600 to get the miles/h, because there are 3600 seconds in an hour.
2ft/s=1.3636368miles/h
Or approximately 1.36miles/h.
The answer to your question is 28%

Answer:
C
Step-by-step explanation:
because to solve it you are seeing which number divises 52 to get you 13
so using the inverse you just need to use multiplication
The two problems are almost identical: you have to set up a system, and then solve it.
In the first case, let and be, respectively, the number of girls and boys.
We know that (the number of girls in the Spanish Club is four more than twice the number of boys). Also, we know that (there are 61 students in total).
So, we have the system
We can use the first equation to substitute in the second
And then solve for :
For the second problem, let and be the number of pins knocked down by, respectively, Carrie and John. Just like before, we have the system
And you can solve it in the very same way we solved the previous one.
Answer:
x=24.621
Step-by-step explanation:
tan(72)=x/8
tan(72)×8=x
x=24.621
