The number of pictures in a movie that is 90 minutes long is 129600 pictures

<em><u>Solution:</u></em>

Given that motion picture camera at normal speed takes 24 pictures per second

To find: number of pictures in a movie that is 90 minutes long

From given question,

1 second = 24 pictures

We have to find for 90 minutes

We know that,

1 minute = 60 seconds

Therefore, convert 90 minutes to seconds

1 x 90 minute = 60 x 90 seconds = 5400 seconds

Therefore, now find the number of pictures in a movie that is 5400 seconds long

1 second = 24 pictures

5400 seconds = 5400 x 24 pictures = 129600 pictures

Thus number of pictures in a movie that is 90 minutes long is 129600 pictures

A sport watch with an original price of $86 is on sale for $60.20. What is the percent of discount?
Anarel [89]
You need to first calculate the amount of lost money, which is 86-60.2=25.8 To find the discount, you need to put this over the initial price, or 86. This equals 0.3, which is 30 percent.
