Answer:

7 hours with 10 minutes

Step-by-step explanation:

First, find how much minutes it takes to get to 9 a.m, which is 25 minutes.

Then, count up to 3 p.m, which is 6 hours.

Then, add the 45 minutes to 25, which will give you 70, but since you have more than 60 minutes, convert those 60 minutes to an hour adding that up to 7 hours and ten minutes.

Answer:

430 minutes or 7 hours and 10 minutes

Step-by-step explanation:

From 8:35 am to 9 am is 25 minutes. There are 60 minutes in an hour and 9 am to 3 pm is 6 hours. 3:00 to 3:45 pm is an additional 45 minutes.

60 minutes x 6 hours = 360 minutes

360 + 25 + 45 = 430 minutes

What is the median of these numbers: 11, 13, 4, 9
Rom4ik [11]

Answer:

10

Step-by-step explanation:

11, 13, 4, 9

In order to find the median we must first arrange the numbers in order (Least to greatest)

4, 9, 11, 13

If there is 2 numbers in the middle: the median is their average

If there is only one number in the middle, that number is the median.

Since there are two numbers (9 and 11) we have to take their average.

(9+11) / 2 = 20 / 2 = 10

The median is 10!
