Answer:The ratio of the number of children who can swim to the number of children who cannot swim=2:1
Step-by-step explanation:
Number of children that can swim = N umber of boys and girls that can swim =23+17 =40
Number of children that cannot swim = N umber of boys and girls that cannot swim=9+11=20
=40:20
=2:1

50 is the answer if 30 is 60% of the club that means 10 is 20% and you just skip count until it reaches 100%
We are given with the expression y<span> = b cos t + t2 sin t and is asked to differentiate the function in terms of t. Based in the power law and law of products, we apply these to the given expresssion. the derivative is y' = -b sin t + t^2 * (cos t) + sin t * 2t. This is equal to </span>y' = sin t (-b +2t) + t^2 cos t.
Answer:
62, 71, 80
Step-by-step explanation:
to figure out the rule we can minus 51 and 42 which is 9. so you know the rule we can now figure out the next three rules.
The answer is 51+9, the 62+9 and so on.
