A. there are 20 boys and 30 girls.
B.
68.7 out of 100 Boys
Girls im not sure, maybe someone else can answer that sorry
Hope I'm right and this helps sorry i didn't get girls.
We can solve this problem by the rule of three.
A complete pie chart has 360º.
45º----------------------6 people
360º-------------------- x
x=(360º*6 people) / 45º=48 people.
Answer; 48 people.
I'd say the 3rd one. I haven't done this stuff in 2 years ... me forgot. But if it's not right, then the 1st one!
I want you to know you're smart and you can do this! Good luck!
Substituting the value of X in each of the equations.The best answer would be the equation satisfying both of the sides.
Therefore,
Substituting the values in the second equation gives the best answer.
8(1.2)^2 + 34 = 45.52 centimeters
