Which figure could be the result of dilating this rectangle with a scale factor between 0 and 1?
Answer:
When we dilate a figure with a scale factor between 0 and 1, the size of the figure shrinks but maintains the same orientation as the original figure. Therefore the correct option is B.

Everyone thought that Martha Mathy was trying to start a new fashion trend when she started wearing socks that did not match. her "look" started to catch on, and pretty soon all the kids at her school were wearing mixed-up socks, too. Rita Writer, a reporter for the school paper, interviewed Martha about the new sock trend. " Wat gave you the idea to wear mismatched socks?" Rita Asked.
"Its simple mathematics," Martha replied. "you see, I have 18 socks at home but no two are the same. with just these 18 socks, I can create over 100 unique pairs of mismatched socks." Rita found this hard to believe, so she checked it out. Was Martha correct?
Answer:
There are 153 combinations
Combinations - any two from eighteen is given by the formula 18C2 or 18! / (2!*16!)
= 18 * 17 / 2 = 153
OK that is the maths - now the explanation
The first sock can be any of 18
The second sock can be any of 17 (one already been selected and they must be mismatched)
Therefore there are 18*17 = 306 permutations she could make
However the question asks for "combinations" not "permutations"
A green sock on the right foot and a yellow sock on the left foot is deemed to be a different "permutation" to a yellow sock on the right foot and a green sock on the left foot. HOWEVER, they are regarded as the same "combination" in both cases you have one green and one yellow sock.
Therefore for combinations we must divide the 306 permutations calculated above by 2 = 153
FYI Walton has incorrectly given you the value of 18!. That would only apply if Martha Mathy had 18 feet!

Answer:
x = 3
y = 4
Step-by-step explanation:
You need to get ridof the 2y so add the equations together:
3x - 2y = 1
*add
2x + 2y = 14
5x + 0 = 15
5x = 15
*divide by 5
x = 3
Now that we have x we can find y by substituting
2(3) + 2y = 14
6 + 2y = 14
* subtract 6
2y = 8
*divide by 2
y = 4
Hope this helps :)

Find the interquartile range (IQR) of the data in the box plot below.
eggs
Number of eggs laid
Answer:
5
Step-by-step explanation:
The interquartile range is the 3rd quartile minus the 1st quartile. The 3rd quartile is 8 and the 1st quartile is 3.
8 - 3 = 5
The interquartile range (IQR) of the data is 5.
From the box plot we can write,
Minimum = 2
First Quartile, Q1 = 3
Median = 6
Third Quartile, Q3 = 8
Maximum = 10
So, Interquartile range (IQR)
= Q3 - Q1
= 8 - 3
= 5
Thus, the interquartile range (IQR) of the data is 5.

which shows 2÷3 written as a fraction? (options) a. 2/3 b. 3 1/2 c. 3/2 d. 2 1/3
Answer:
A. 2/3
Step-by-step explanation:
Fraction is another way to divide , So in some math problems they want you to either flip the fraction or divide the numbers .
Option A is correct, the expression 2÷3 written as a fraction is 2/3.
What is Fraction?A fraction represents a part of a whole.
We have to write 2÷3 as a fraction.
Two divided by three.
We have to split the number two by three parts.
We know that any division expression can be written as a fraction, the numerator is a part and denominator is a whole.
Two is the numerator and three is the denominator.
The numerator represents the part and three represents the whole.
This we can write in fraction as 2/3.
Two by three is the fraction form of two divided by three.
Where as [tex]3\frac{1}{2}[/tex], is not a fraction, it is a mixed number.
3/2, is not equivalent to 2 ÷ 3, it represents the fraction one and a half and [tex]2\frac{1}{3}[/tex] is not equivalent to 2 ÷ 3, it represents the mixed number two and one-third.
Hence, Option A is correct, the expression 2÷3 written as a fraction is 2/3.

Write two mixed numbers so that all rules are applied:
1. One number is larger than the other by 4 2/3
2. The difference of the numbers is equal to the smaller number.
3. The sum of the numbers is natural number
Answer:
Step-by-step explanation:
“One number is larger than the other by 4 2/3”
x = y + 4⅔
“The difference of the numbers is equal to the smaller number.”
x-y = y
x = 2y
y + 4⅔ = 2y
y = 4⅔
x = 2y = 9⅓
“The sum of the numbers is natural number”
x+y ∈ ℕ
9⅓ + 4⅔ = 14 ∈ ℕ
