Answer:
A
Explanation:
The whole numbers are the numbers that we use to count like 1, 2, 3, ...
Then, integer numbers are the set that contains the whole numbers and the negative numbers, so the integer number are like ... -3, -2, -1, 0, 1, 2, 3, ...
Therefore, -648 is an integer number.
Finally, the rational numbers are numbers that can be written as a/b, where a and b are integers.
So, the answer is A because rational numbers contain integer numbers, integer numbers contain whole numbers and -648 is a integer number.
Answer:
10 square in.
Step-by-step explanation:
The rectangles are similar by a scale factor of 3. We can tell because the quotient of two of the corresponding sides, 18 and 6, is 3 (18/6=3)
That means the width of ABCD is 3 times the width of WXYZ.
Let's say the width of ABCD is x. Then 18*x=90 because that's the area.
x=90/18=5
Now we have the width of ABCD, 5, so to get the width of WXYZ, we divide by 3, which is 5/3.
Now to get the area of WXYZ, we can do 5/3, the width, times 6, the length, which is 30/3=10.
