[Question]At football tryouts, the coach wanted to see who could throw the ball the farthest. Parker threw the ball 16 yards. Grant threw the ball 25 percent farther than Parker and Kyle threw the ball 2 times farther than Grant. Compared to Parker, how much farther did Kyle throw the ball?
[Answer]Grant threw the ball 25% farther than Parker. If Parker threw the ball 16 yards, then Grant threw it 16 * .25 = 4 farther. In total, Grant threw the ball 16 + 4 = 20 yards. Kyle threw 2 times farther than Grant so Kyle threw the ball 2 * 20 = 40 yards. If Kyle threw the ball for 40 yards and Parker threw for 16 then Kyle threw the ball 40 - 16 = 24 yards farther. The answer is 24.
Q: Tommy has 10 more sheets than Jimmy does. If Jimmy has 32 sheets, how many more sheets will Jimmy have than Tommy if his friend Ashton gives him 40 sheets.
A: If Jimmy has 32 sheets, and Tommy has 10 more sheets than Jimmy does, Tommy has 10 + 32 = 42 sheets. When Ashton gives Jimmy 40 sheets, his total number of sheets increases to 32 + 40 = 72. The number of sheets that Jimmy now have than Tommy is 72 - 42 = 30. The answer is 30.
Question: Mary is counting the number of minnows in the pond. 40% of the minnows have red bellies, 30% have green bellies and the rest have white bellies. If 20 minnows have red bellies, how many minnows have white bellies?
Answer: First find the total number of minnows by dividing the number of red minnows by the percentage of minnows that are red: 20 minnows / 40% = 50 minnows. Then subtract the percentages of red - and green - bellied minnows to find the percentage of white - bellied minnows: 100% - 40% - 30% = 30%. Then multiply the total number of minnows by the percentage that have white bellies: 30% * 50 minnows = 15 minnows. The answer is 15.
[Question]In a house, there are 16 cats. Two of them are white, and 25% of them are black. The rest of the cats are grey. How many grey cats are in this house?
[Answer]In this house, there are 16 * 25 / 100 = 4 black cats. If there are two white cats, that means that there are 16 - 4 - 2 = 10 grey cats in this house. The answer is 10.
Q: A rectangular plot of private property is fenced in by a chain-link fence. The long sides of the plot are three times the length of the short sides. One short side of the fence is rusted from being hit by a sprinkler and needs to be replaced. If all the sides of the fence together are 640 feet long, how many feet of fence need to be replaced?
A: Let S be the length of the short side of the fence. Thus, the length of a long side of the fence is 3S. There are 2 of each side, so the whole fence is 2S + 2 * 3S = 2S + 6S = 8S long. The whole fence is 8S = 640 feet long. Thus, the short side of the fence that needs to be replaced is S = 640 / 8 = 80 feet long. The answer is 80.
Question: There are 25 roses in a garden. There are 40 tulips. There are 35 daisies. What percentage of flowers are not roses?
Answer:
There are 25 + 40 + 35 = 100 flowers total. There are 40 + 35 = 75 flowers that are not roses. Therefore, (75 / 100) * 100 = 75% of the flowers are not roses. The answer is 75.
