The answer to your question is A. rational numbers.
Rational numbers are closed under any set of operations.
Integers are not closed under division because 1/2 is not an integer.
The set {-1, 0, 1} is also not closed under division because -1/5 does not fall in that set.
Whole numbers are not closed under division because 5/3 will produce a number that is not a whole integer.
Your answer is A. rational numbers.
a: draw a rectangle an label one side 80 and the other 115
b: 1560 Yards
Okie, so percent decrease is the amount loss divided by the original number and multiplied by 100 to find the percent. This is because you are finding the amount loss in terms of the total amount - percent basically.
The amount loss : 4 feet
4 feet/ 12 feet = .3333 (ratio of how much cut) multiply by 100 --> 33.3% decrease. From 12 feet to 8 feet is a 33.3 % decrease. I hope this helps :-)
The answer is kindly 21 (100% correct)
Answer:
A = 4/5 ft
Step-by-step explanation:
Area = length x width
A = 2 2/5 x 1/3
Turn the mixed number into an improper fraction:
2 2/5 = 12/5
A = 12/5 x 1/3
A = 12/15
You can divide the top and bottom by 3:
A = 4/5
