Answer:
30
Step-by-step explanation:
There are 146 - 84 = 62 girls
ratio is 84:62
simplifies to 42:31
Answer:
26
Step-by-step explanation:
You can determine the slant height of this cone by forming a right triangle with the radius, and height. Therefore, the slant height is:
sqrt(10^2 + 24^2) = sqrt676 = 26
Area = 36 = length*width
Then, while the area is constant the product length*width is constant.
Length and area are inversely related.
That means that to keep the same product (area), length vary in inverse proportion to width.
If you increase length, widht has to decrease to satisfy this relation:
width = 36/length
Of course, you can also say: length = 36 / width.
