First one is C (18 sq units)
Second one is A (12sq2 units)
Multiply 4 * 5, which equals 20, and add the two zeroes(from 40 and 50) on the end.
That gives us:
2000
Answer:
28 questions
Step-by-step explanation:
In the first 10 mins she answered 2/5 of 40 which is 16. The remaining amount is 24 questions and half of that is 12. So she answered 12 questions in 15 mins. Finally you add them to get 28 questions in 25 minutes.
You have to put a picture of the problem
Multiply 12 by 4%, or 4/100, and 4/100 simplifies to 1/25. 12/1 x 1/25 = (12 x 1)/(1 x 25) = 12/25, which equals 0.48. So, the smallest frog is 0.48 inches long, but can be rounded to 0.5 inches long.
