Answer:
400 seconds
Step-by-step explanation:
To find the distance, you have to multiply. Since each second=20 meters, you have to multiply 20 x 20 because there are 20 seconds.
Answer:
4 chocolates
Step-by-step explanation:
Before Luke started eating, there were 8. This is 2/3 of what Sara had to start with, so she started with 12. That is 3/4 of what Mike started with, so he started with 16.
Jill left 4/5 of what she started with, so she must have started with 20. Jake ate 1/6 and left 5/6, so 20 is 5 times the number Jake ate.
Jake ate 4 chocolates.
___
Jill ate 4; Mike ate 4; Sara ate 4; and Luke ate 4.
Your answer is because 4•1=4 and 4•2=8
Answer: 
Step-by-step explanation:
We need;
We don't have the radius, but we do have the diameter. A diameter is twice the radius. Therefore, we can divide the diameter by 2 in order to obtain the radius.
Now plug this info into the formula.
![(3.14)(12yd)[(12yd)+\sqrt{(18yd)^2+(12yd)^2} ]](https://tex.z-dn.net/?f=%283.14%29%2812yd%29%5B%2812yd%29%2B%5Csqrt%7B%2818yd%29%5E2%2B%2812yd%29%5E2%7D%20%5D)
Let's solve the square root first.
![(3.14)(12yd)[(12yd)+\sqrt{324yd^2+144yd^2} ]](https://tex.z-dn.net/?f=%283.14%29%2812yd%29%5B%2812yd%29%2B%5Csqrt%7B324yd%5E2%2B144yd%5E2%7D%20%5D)
![(3.14)(12yd)[(12yd)+\sqrt{468yd^2} ]](https://tex.z-dn.net/?f=%283.14%29%2812yd%29%5B%2812yd%29%2B%5Csqrt%7B468yd%5E2%7D%20%5D)
![(3.14)(12yd)[(12yd)+\sqrt{468yd^2} ]\\(3.14)(12yd)(12yd+21.63yd)](https://tex.z-dn.net/?f=%283.14%29%2812yd%29%5B%2812yd%29%2B%5Csqrt%7B468yd%5E2%7D%20%5D%5C%5C%283.14%29%2812yd%29%2812yd%2B21.63yd%29)
Now solve the sum
