Answer: There is 36 girls and 54 boys.
Step-by-step explanation: If there is 36 girls and there is 3 boys for every 2 girls that means half of 36 is 18 so do 18 times 3 which will equal 54 boys.
54+36=90
Answer:432 whats the other option 4300
Step-by-step explanation:
This looks like an ellipse.
Complete the square for y: 9(y²-6y-7)=9(y²-6y+9-9-7)=9((y-3)²-16).
Rewrite the equation:
4x²+9(y-3)²-144=0; 4x²/144+9(y-3)²/144=1; x²/36+(y-3)²/16=1.
Standard equation of an ellipse is (x-h)²/a²+(y-k)²/b²=1, where (h,k) is the origin or centre.
This is the equation of an ellipse with centre (0,3), a=6 and b=4 (semimajor and semiminor axes).
Here, 3x + 6x = 90
9x = 90
x = 90/9
x = 10
In short, Your Answer would be 10
Hope this helps!
Where are the options ? But I know 5% of 352 = 17,6
