The final answer should be -49/168.
Step-by-step explanation:
A=P(1+R)
A/P=1+R
(A/P)-1=r
(3000000/20000)-1=r
149=r
Answer:
27 girls and 15 boys
Step-by-step explanation:
To solve this, I just used guess and check.
9:5 is a ratio, which means we can multiply each side by any number as long as we do it to both sides.
If we multiply the ratio by 3, we get (9 x 3) : (5 x 3) which is 27:15
And as it turns out, 27-15 is 12, which in this context means there are 12 more girls in drama club, so it works out.
1). Recall the formula for the volume of a cylinder:
Volume = (pi) x (radius of the round end)² x (length or height) .
2). Gather together the number you'll use for pi, the radius of the
cylinder's round end, and its length or height. Make sure that the
radius of the round end and the length or height are in the same units.
If they're not, then convert something so that they are.
3). Write each number into its place in the formula.
4). Perform the indicated operations. The final number is the
volume of your cylinder.
