If the 5 of them weigh 1/4 of a ton
then 1 of them weigh x
5/1 = 1/4//x Do you see what happens? Just by writing down the givens you get a proportion. It will work better for you if you change the 1/4 to 0.25
5/1 = 0.25/x Now it looks like an ordinary proportion. Cross multiply
5x = 0.25*1 divide by 5
x = 0.25/5
x = 0.05 tons. We better change this to pounds.
1 ton = 2000 pounds
0.05 ton = x
1/0.05 = 2000/x Cross multiply
x = 2000 * 0.05
x = 100 pounds.
Is A & C.
Explanation:
A. Median for sea turtles:
The set is odd, so median is the middle number - 4
The koi set had 10, even number, so the median for the koi is the average of the 2 middle: 4+3=3.5
Turtles > koi
C. The ages of koi are more spread out - 10. The turtles are only 5.
Then the car will travel 51 miles on 1 gallon of diesel
Here are the answers to the given questions above. The sets of numbers that are closed under multiplication are the following: Whole numbers, and Integers. The answers would be options A and D. Whole numbers are closed<span> only </span>under<span> addition and </span>multiplication. Integers are closed under<span> addition, subtraction, </span>multiplication<span>, and division (with the exception of division by 0). Hope this answer helps.</span>
