Answer:
Boys = 150
Girls = 315
Total Boys and Girls 465
Step-by-step explanation:
We call x the number of boys and we call y the number of girls.
So we have to find the total number of children
We know that
Now we substitute the second equation in the first and solve for y.
Now we find x.
Finally we have that:
Boys = 150
Girls = 315
Total Boys and Girls 465
Answer:
D 852 cm^2
Step-by-step explanation:
The lateral surface area of a cylinder is given by
LSA = 2*pi*r *h
We know the diameter which is equal to 2*r = 11.3, we can approximate pi by 3.14 and h = 24
LSA = 11.3 * 3.14 * 24
LSA =851.568 cm^2
Rounding to the nearest whole number
LSA = 852 cm^2
