50 girls attended the trip.
80 boy + 50 girls = 130 total students
8x10 =80
5x10=50
multiply both by 10.
Answer:
Final answer is 47.5%.
Step-by-step explanation:
Let the missing percent is x.
Then x percent of 40 can be written as: 
.
Given that resulting percent value is 19.
So we can set both equal.
So the final answer is 47.5%.
Answer:
48
Step-by-step explanation:
We have that the volume of a cylinder is given by:
V = pi * (r ^ 2) * h
In this case we know the diameter, we know that the radius is half the diameter like this:
r = d / 2
r = 8/2
r = 4
Now we know that the V equals 768 pi
we replace and we have:
768 * pi = pi * (4 ^ 2) * h
768 = 16 * h
h = 768/16
h = 48
Therefore the value of x would be 48 cm
<span>Surface area</span> = 2πr(h+r) = 2 * 3.14 * 3(8+3) = 207.24 yd²
