Answer:
16 girls
Step-by-step explanation:
If you have 12 boys, and the ratio is 3;4, that means you multiplied 3 times 4. To find the answer to this problem, you need to multiply 4 by 4 because you multiplied 3 by 4, and you always have to multiply or divide by the same thing if its a ratio.
<em>Answer:</em>
720.
Step-by-step explanation:
So, 10% of 180 is 18, so x 18 by 40 is 720, (do the reversed operation) which will give you your answer..
Or you could go 10% of 40 which is 4, and then do 180 x 4, which will also give you a answer of 720.

X objects in t seconds.....how long to sort 15 objects....so x = 15
t = 0.007(15^2) + 0.003(15)
t = 0.007(225) + 0.045
t = 1.575 + 0.045
t = 1.62 seconds <===
