Answer:
202 meters
Step-by-step explanation:
Since this is a right triangle, you can plug it into Pythagoras theorem of a squared plus b squared equals c squared. So 198 squared plus 40 squared equals 40804. Square root this and it gives you 202 meters.
Answer:
Step-by-step explanation:
First find the population density of AZ and then compare it to the US average of 87.4 people per square mile:
6,482,505
---------------- = 56.9 people per square mile
113,998
The ratio of AZ's population density to the national average is:
56.9
--------- or 569/874
87.4
Given:
pH = 4.2 of tomato
Required:
hydrogen-ion concentration [H+]| for tomato juice
Solution:
The formula for the pH relating hydrogen ion concentration is pH =
-log[H+] where H+ is the hydrogen ion concentration. so, substitute the value
of pH
pH = -log[H+]
4 = - log[H+]
-4 = log[H+]
10^-4 = [H+]
[H+] = 1x10^-4M
