Movie tickets for day time movies are $8.00 per person. On Tuesday days, there is a 20% discount for the same day time movie tic
Lerok [7]

Answer:

$19.2

Step-by-step explanation:

20% of 8 is 1.6 (let me know if you need me to explain how to find that).

This means that, with a 20% discount, the price of a ticket would be $6.4.

If there are three of you, multiply 6.4 by 3.

That gets you to 19.2

What is 10 over 64 in simplest form
kykrilka [37]
To write a fraction in simplest form, you have to divide the numerator and the denominator by their greatest common factor.

Factors of 10: 1, 2, 5, 10
Factors of 64: 1, 2, 4, 8, 16, 32, 64
Common Factors: 1, 2
Greatest Common Factor: 2

\frac{10}{64} = \frac{10/2}{64/2} = \frac{5}{32}

A bicyclist heads east at 10km/h. After she has traveled 24.2 kilometers, another cyclist sets out in the same direction going 3
Alona [7]
We know that the first cyclist has traveled 24.2 km at a speed of 10 km/h. Lets use the equation time= \frac{distance}{speed} to find the time of the first cyclist:
t= \frac{24.2}{10}
t=2.42
So, we know that she has traveled for 2.42 hours.
 
We also know that after she has traveled for 2.42 hours another<span> cyclist sets out in the same direction, so if </span>t represents the time of our first cyclist, <span>the time of our second cyclist will be </span>t-2.42.

Now we are going to use the equation distance=(speed)(time) to relate the speeds and times of the two cyclist:
For the first one:
distance=10t equation (1)
For the second one:
distance=30(t-2.42) equation (2)

Replace (1) in (2)
10t=30(t-2.42)
The only thing left now is solve for t:
10t=30t-72.6
-20t=-72.6
t= \frac{-72.6}{-20}
t=3.63

We can conclude that the second cyclist will catch up the first cyclist after 3.63 hours.
