We can start with the basics. What we know is that this entire trip took 6 hours. So the travelers were able to walk on the level, uphill, and downhill in a total of 6 hours. 

A level mile takes 1/4 of an hour (15 minutes). An uphill mile takes 1/3 of an hour (20 minutes). A downhill mile takes 1/6 of an hour (10 minutes). So, to go and return over the same mile takes half an hour. This means that in 6 hours, they went 12 miles and came 12 miles back. So they went a total of 24 hours. 

If the 12 miles had been all level, it would have taken approximately 3 hours. It the 12 miles had been all uphill, it would have taken approximately 4 hours. When reaching the peak, 3.5 hours would have been the approximate time it took them to reach the top since it is in between. <span />

A shop sells newspapers for a profit of 0.5%. His sales for the month of January were $8341.50. How much of this is profit?
Doss [256]
Amount of sales  of newspapers for the month of January = $8341.50
Percentage of profit for which the newspaper is sold = 0.5%
Then
Amount of profit made in the month of January = 0.5% * 8341.50 dollars
                                                                           = (0.5/100) * 8341.50 dollars
                                                                           = 4170.75/100 dollars
                                                                           = 41.707 dollars
                                                                           = 41.71 dollars
So the shop makes a profit of $41.71 in the month of January by selling newspapers worth $8341.50. I hope the procedure is perfectly clear for you to understand.

Write an inequality to describe the region. the region between the yz-plane and the vertical plane x = 3
deff fn [24]

Write an inequality to describe the region is x < 0 < 3

Inequalities in three dimensions:

When an inequality representing a region in three dimensions contains only one of the three variables, then the other two variables have no restrictions. We use inequalities to describe solid regions in three dimensions.

Answers and Explanation:

The y z - plane is represented by the equation x = 0

As the region is between this plane and the vertical plane x = 3, we will get the inequality 0 < 0 < 3

Thus, the desired inequality is  

0 < 0 < 3.
