Step-by-step explanation:
members of "M" = 2,3,5,7,11
members of "N" = 1,2,3,4,6,12
M∪N = 1,2,3,4,5,6,7,11,12
M∩N = 2,3
intersection is the overlapping numbers in the sets
union is the set with all the numbers but they cannot be duplicates
The members of "M" [tex]=[/tex] [tex]2,3,5,7,11[/tex]
The members of "N" [tex]= 1,2,3,4,6,12[/tex]
M∪N [tex]= 1,2,3,4,5,6,7,11,12[/tex]
M∩N [tex]= 2,3[/tex]
What is Prime number ?
A prime number is a natural number greater than 1 that is not a product of two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number.
According to questions, M = {Prime integers between [tex]1[/tex] and [tex]11[/tex]}
and N = { factors of [tex]12[/tex]}.
We have to find the members of M, the members of N, M∪N and M∩N.
M = {Prime integers between [tex]1[/tex] and [tex]11[/tex]} [tex]=[/tex][tex]2,3,5,7,11[/tex]
N = { factors of [tex]12[/tex]} [tex]= 1,2,3,4,6,12[/tex]
So, M∪N [tex]= 1,2,3,4,5,6,7,11,12[/tex]
and M∩N [tex]= 2,3[/tex]
Hence, we can conclude that
The members of "M" [tex]=[/tex] [tex]2,3,5,7,11[/tex]
The members of "N" [tex]= 1,2,3,4,6,12[/tex]
M∪N [tex]= 1,2,3,4,5,6,7,11,12[/tex]
M∩N [tex]= 2,3[/tex]

Step-by-step explanation:
4) The triangle on the right is an equilateral
Find the value of X and Y
Answer:
angle Y is 29 degrees
angle X is 120 degrees
Step-by-step explanation:
Well, if the triangle is an equilateral, then all the angles are equal to
60 degrees
that means the the angle at the top point is 60+31 = 91 degrees
the right point is 60 degrees
every triangle has 180 degrees total
180 - (91+60) = 29 degrees
NOW FORGET ABOUT THE EQUILATERAL FOR A BIT
180 = 31+x+29
simplify
180 = 60+x
subtract 60 from both sides
120 = x

Hope this helped!
Answer:
(x + 5)(x + 4)
Step-by-step explanation:
Assuming you require the expression to be factored
Given
x² + 9x + 20
Consider the factors of the constant term (+ 20) which sum to give the coefficient of the x- term (+ 9)
The factors are + 5 and + 4, since
5 × 4 = + 20 and 5 + 4 = + 9 , thus
x² + 9x + 20 = (x + 5)(x + 4) ← in factored form

a 21-ounce box of cereal costs $3.87.what is the unit price of the cereal?
Answer:
$0.18 per ounce
Step-by-step explanation:
$3.87/21=0.1842857....
Round to the nearest $0.01
1 ounce box cost $0.182.
What is Unitary method?It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
Steps to Use Unitary MethodFirst, let us make a note of the information we have. There are 5 ice-creams. 5 ice-creams cost $125.
Step 1: Let’s find the cost of 1 ice cream. In order to do that, divide the total cost of ice-creams by the total number of ice-creams. The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-creams = 125/5 = 25. Therefore, the cost of 1 ice cream is $25.
Step 2: To find the cost of 3 ice-creams, multiply the cost of 1 ice cream by the number of ice-creams. The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75. Finally, we have the cost of 3 ice-creams i.e. $75.
Given:
21-ounce box of cereal costs $3.87
So, 1 ounce box cost= 3.84 / 21
= $0.182
Hence, 1 ounce box cost $0.182.

dilation the center of dilution is the origin b (2,3) and B(-4,-6) what is the scale factors of this dilation that transformed a B into B
Given:
Consider the two points are B(2,3) and B'(-4,-6).
Center of dilation is the origin.
To find:
The scale factors of this dilation that transformed B into B'.
Solution:
If a figure dilatated by scale factor k and center of dilation is the origin, then
[tex](x,y)\to (kx,ky)[/tex]
It means, the point after dilation is
[tex](x',y')=(kx,ky)[/tex]
where, k is the scale factor.
[tex]k=\dfrac{x'}{x}[/tex]
x-coordinate of image is -4 and x-coordinate of original point is 2.
[tex]k=\dfrac{-4}{2}[/tex]
[tex]k=-2[/tex]
Therefore, the scale factor is -2. It means, the point and image lie on the opposite sides of center of dilation.

Answer:
They are not equivalent.
Step-by-step explanation:

(x-38)
Answer:
x = 109
Step-by-step explanation:
The figure has one pair of parallel sides and is a trapezoid.
The lower base angle is supplementary to the upper base angle on the same side, thus
x + x - 38 = 180 , that is
2x - 38 = 180 ( add 38 to both sides )
2x = 218 ( divide both sides by 2 )
x = 109

Answer:
200 feet per minute

The value of x is 42. Multiply the top and bottom by 6 because the numerator in the first fraction is 2 and the numerator for the second fraction is 12. When you multiply 2 by 6, you get 12. You have to do the same for the denominator. multiply 7 by 6. You get 42. The value of x is equal to 42. Hope this helps.
Answer:
42
Step-by-step explanation:
First, you cross multiply.
12 x 7= 84
2 multiplied by x will give you 2x.
Now, you have the equation below left:
84=2x
Then, you divide by 2 on both sides (in order to leave x by itself):
84/2= 42
x=42

Prove that when 2 lines intersect each other ,then the vertically opposite angles formed are equal.
plz help fast
Answer:
Because both lines intersect at one given point, this means that wherever they intersect both lines will have the same length on each side because that one point serves as the half way point between the intersection. meaning that if two lines cross and it creates the vertical angle of 150⁰ then by definition the side that is across that intersection point will also be 150⁰
Answer:
Step-by-step explanation:
If two lines i.e. AB & CD intersect each other. They have two pair of opp. angles.
i.e.
∠AOC,∠DOB,∠AOB,∠COB.
To prove :- ∠AOC=∠DOB & ∠AOD=∠COB
Proof :-
∠AOC+∠AOD=180 °
[linear pair] ___(1)
∠AOD+∠BOD=180°
[linear pair] ___(2)
from eq. (1) & (2)
∠AOC+∠AOD=∠AOD+∠BOD
i.e. [∠AOC=∠BOD]
Similarly [∠AOD=∠COB]
Hence proved.
