Answer:
Hello there! How are you doing? I am doing fine! I'll answer the question now.
So basically, to find a missing side length of a triangle you have to use Pythagorean theorem, which is A^2 + B^2 = C^2. Plug in 11^2 and 9^ = C^2 since we need to find the side length of C. 11 squared is 121 and 9 squared is 81, so you're left with, 121 + 81 = C^2. You are then left with, after adding, 102 = C^2. You then would take the square root of 202 and get 14.20 as the length of C. Now it is closet to 15 cm, so we can assume that side length of side C, would be indeed 15 cm, not 20 cm.
Hope this helped! I can help with other stuff too! And bye! :)

Answer
Tyler to do the job alone =18/1 = 18 hrs
Solution
It takes Tyler twice as long as Kyle to complete the same job.
efficiency of Kyle is twice the efficiency of Tyler
Let x be the efficiency of Tyler the efficiency of Kyle is 2x
efficiency of Tyler : efficiency of Tyler = x :2x =1:2
Therefore total efficiency = 1 + 2 =3x
The total job = efficiency x total time
Here total time to complete the job=6 hrs
Total job =18
Time taken to complete the job =Total job/efficiency
Tyler to do the job alone =18/1 = 18 hrs
Kyle to do the job alone =18/2 = 9 hrs
Step-by-step explanation:
Start with the average. (of your data set)
Find how much each data value deviates from the average (difference of average and data value).
Take the absolute value of each difference.
Add all of these absolute values.
Divide by the total number of data values.
Answer:
c-2
Step-by-step explanation:
You are given the equation 4y-1=7,
if you add 1 to each side of the equation to isolate 4y on the left side of the equal sign you will be left with 4y=8
divide each side by 4 and you will get y=2
