The hypotenuse of the triangle would be the diameter of the semi circle.
Using the Pythagorean theorem you can find that.
8^2 + 6^2 = x^2
64 +36 = x^2
100 = x^2
x = √100
x = 10
The diameter is 10, now find the circumference.
Circumference = diameter x PI = 10 x 3.14 = 31.4
Since it is a semi circle, the circumference would be 1/2 of that.
31.4 / 2 = 15.7
The perimeter would be 8 + 6 + 15.7 = 29.7

Answer:
27525.4902
Step-by-step explanation:
First need to add the total number of employees:
14+11+17+3+5+1=51
Now multiply the salary for each number of employees then add to have the total:
14x21000+11x22800+17x24800+3x32200+5x38500+1x148300= 1403800
Now to obtain the mean value just divide the total salary by the total number of employees:
1403800/51= 27525.4902
the mean salary is $27,525.49
D. combine like terms, 4+7 is 11 and -3 and -10 is -13
