Question 151993: I need help with this. This is the work I have done, but I want to see if it is correct. Thanks!
A rectangular parking lot is 100 ft longer than it is wide. Determine the dimensions of the parking lot if it measures 500 ft diagonally.
w + (w + 100) = 500
2w + 100 = 500
2w + 100 – 100 = 500 – 100
2w = 400
w = 400/2
w = 200
200 + (200 + 100) = 500

Question 152112: I would greatly appreciate your help with this word problem.
Jonah was visiting his grandfather, who has a large jellybean collection. When he asked if he could have some he said yes, if he could solve a problem for him. He told him that he has three jars, containing either all red jellybeans, all green jellybeans or red and green jellybeans. Each jar is covered so that no one can see the color of the jellybeans. One jar is labeled red, the second green and the third red-green. The catch was that none of the jars was correctly labeled. He could reach into one jar, remove one jellybean and look at it. He would then have to tell him the correct color of the jellybeans in each jar. Which jar should he choose a jellybean from and how does that help him in labeling the jars correctly.
Initally, I thought that if he pulled from the jar labeled red but got a green jellybean then he would know how to label the jars. This doesn't ring true since there is a mixed red-green jar.
Jar Red = either green or mixed beans
Jar Green = either red or mixed beans
Jar Red-Green = either red or green beans

Question 152240: The anual cost in dollars for removing p% of the toxic chemicals from a town's water supply is given by the formula
C(p) = (500,000)/100-p
use the formula to determine the cost for removing 99.5% of the toxic chemicals
I did C(99.5) = (500,000)/100-99.5
99.5 C = 500,000/.5
C = 1005.025
this just can't be right because It costs 50,000 at 90% and 100,000 at 95%
