You would use the pythagorean theorem to solve this equation: a^2 + b^2 = c^2
12^2 + b^2 = 20^2
b^2 = 16
x = 16
Answer:
1. 47.1% 2. 69.4% 3. 72.9% 4. 55.6%
Step-by-step explanation:
you just have to add both the numbers and divide the one you are trying to find is liked by the total of both.
ex.
what precent of chicago likes rain?
chicago rain 143 snow 59
143+59=202
143/202=70.7%
Given that the diameter of a human hair
Given that the diameter of a spider's silk
Now we have to find how much greater is the diameter of a human hair than the diameter of a spider's silk.
To find that we just need to subtract the given numbers.
Since powers are not same so let's make them equal
now we can easily subtract the coefficients that is 3 from 9
Hence final answer is .
Answer:
Step-by-step explanation:
Given:
Each city is exactly 120 miles from the other two.
Average rate from city A to city B = 60 mi/hr
Average rate from city B to city C = 40 mi/hr
Average rate from city c to city A = 24 mi/hr
We need to find the Dale's average rate for the entire trip.
Solution:
First we find the total time and total distance by following way.
Time taken to travel from A to B =
Time taken to travel from B to C =
Time taken to travel from C to A =
So, total time taken =
Total distance = 120 + 120 + 120 = 360 miles
Using average speed formula.
Therefore, the average rate for the entire trip
