[Question]The tallest of 3 trees is 108 feet. The middle sized tree is 6 feet less than half the height of the tallest tree. The smallest tree is 1/4 the height of the middle tree. How tall is the smallest tree?
[Answer]Tallest Tree: 108 feet. Middle sized tree:(108 / 2) - 6 = 48 feet. Smallest tree:48 / 4 = 12 feet. The answer is 12.
Q: Albert has three times as many marbles as Angela. Angela has 8 more than Allison, who has 28 marbles. How many marbles do Albert and Allison have?
A: Angela has 8 more marbles than Allison who has 28 so Angela has 8 + 28 = 36 marbles. Albert has three times as many marbles as Angela who has 36 so Albert has 3 * 36 = 108 marbles. Albert and Allison together have 108 + 28 = 136 marbles. The answer is 136.
Question: What is the average age of the 1st and 5th fastest dogs if the 1st fastest dog is 10 years old, the 2nd fastest dog is 2 years younger than the first fastest dog, the 3rd fastest dog is 4 years older than the 2nd fastest dog, the 4th fastest dog is half the age of the 3rd fastest dog, and the 5th fastest dog is 20 years older than the 4th fastest dog?
Answer: If the 1st fastest dog is 10 years old, and the 2nd fastest dog is 2 years younger than the first fastest dog, the 2nd fastest dog is 10 - 2 = 8 years old. The 3rd fastest dog being 4 years older than the 2nd fastest dog, is 8 + 4 = 12 years old. The 4th fastest dog is half the age of the 3rd fastest dog, meaning the 4th fastest dog is 1 / 2 * 12 = 6 years old. The 5th fastest dog is 20 years older than the 4th fastest dog, meaning the 5th fastest dog is 6 + 20 = 26 years old. The total age of the 1st and 5th fastest dogs is 26 + 10 = 36 years. The average age of the 1st and 5th fastest dogs is 36 / 2 = 18 years old. The answer is 18.
[Question]Francine wants to know if a local chemical plant is releasing toxic waste that makes the frogs mutate. In one local pond, she catches 5 frogs with extra legs, 2 frogs with 2 heads, two frogs that are bright red, and 18 normal frogs. What percentage of the frogs have mutated, rounded to the nearest integer?
[Answer]First add up the numbers of the three kinds of mutant frog: 5 frogs + 2 frogs + 2 frogs = 9 frogs. Then add that number to the number of normal frogs to find the total number of frogs: 9 frogs + 18 frogs = 27 frogs. Finally, divide the number of mutant frogs by the total number of frogs and multiply by 100% to find the percentage of frogs that are mutants: 9 frogs / 27 frogs * 100% = 33.333...%, which rounds to 33%. The answer is 33.
