50 since a triangle has to equal 180, trust!
When you simplify the expression you get 38. Hope this helps.
Answer = 38.
2 1/2 x 3 = 7 1/2 = 7 4/8
10 11/8
- 7 4/8
3 7/8
A is the correct answer
The K-constant variation is the factor of the increase-decrease relationship between the x-variable and y-variable which can be stated as y=k*x or x=y/k<span>. For example, if y variable equal 5 and the x variable equal 2 then the k-constant variation equal 2 (calculation y=k*x --> 5=2*2.5). This constant shows the relationship between the variables.</span>
The correct answer is A = 2 x pi x r x h. So basically the answer is C. Hope I helped! :)
