Using the Pythagorean Theorem,
radius^2 = 40^2 + 9^2
radius^2 = 1,600 + 81
radius^2 = 1,681
radius = 41
1) 2x+3 = 5
-3 -3
2x =2
x=1
2) -x + 8 = 5
-8 -8
-x = -3
X=3
Answer: 73.5
Step-by-step explanation:
The percent <em>33 1/3% </em>represents 1/3 of 100%. We can multiply 33 1/3% by 3 and get 100%. We need to find what 24.5 is 33 1/3% of.
Since 1/3 x 3 = 100%, then 24.5 x 3 must equal the number we're trying to find.
24.5 x 3 = 73.5.
Therefore, 24.5 is 33 1/3% of 73.5. I hope this helps, and good luck!
The solution has to be a value of x. Since you already have x, you just have to plug in the value and see what fits. In this case thats the third from the top:
5^2 - 10*5 + 25 = 0
25 - 50 + 25 = 0
0 = 0
Hope it helps!
I think the answer is D hope this helps
