X = boy count
x + 14 = girl count
x +x +14 = 86
2x + 14 = 86
2x = 72
x = 36
x + 14 = 50
There are 36 boys and 50 girls. Hope this helps!
Answer:
(x-8)^2+(y-16)^2 = 4
Step-by-step explanation:
The equation of a circle is given by
(x-h)^2+(y-k)^2 = r^2 where (h,k) is the center and r is the radius
(x-8)^2+(y-16)^2 = 2^2
(x-8)^2+(y-16)^2 = 4
10 is the answer.
You know that there are 4 numbers and you have to add the numbers then divide them by four to get the mean. So all you have to do is reverse the steps, multiply 30 by 4 to get 120, then add 12+50+48 to get 110. Then subtract, 120-110=10. To check if it is correct add 12, 50, 48, and 10 to get 120, then divide by 4 to get 30. And voila, there is the answer. I hope this helped for future problems like this one.
8% of 20 is 1.6
This is because you take the percentage and divide it by 100 so that you have a decimal, then multiply that by twenty. So, 8% ÷ 100 = 0.08 then 0.08 × 20 = 1.6
Hope this helps!
