Answer:
the relation between them are
n(U) = n(X U Y) + n(xūy).
If Hannah gives her younger sister 3 shirts, it does not matter what order she hands them to her. No matter the order, it will still be the same group of 3 shirt. Since order is not important this problem can be solved using a combination.
Specifically, we are asked to find 8C3 (sometimes called "8 choose 3"). This is a fraction. In the numerator, we start with 8 and count down 3 numbers. In the denominator, we start with 3 and count all the way down to 1.
your answer is 56
Im pretty sure the answer is .52 I got this by subtracting the toatl by the sales tax and then dividing that total by how many pencils were bought : 6.70-.42=6.24, 6.24/12=54
ANSWER
139°
EXPLANATION
One of the interior angle properties of a parallelogram is that adjacent interior angles are supplementary.
This means that, the adjacent interior angles add up to 180°.
If
![m \angle \: B = m \angle \: D = 41](https://tex.z-dn.net/?f=m%20%5Cangle%20%5C%3A%20B%20%3D%20m%20%5Cangle%20%5C%3A%20D%20%3D%2041)
Then
![m \angle \: C + m \angle \: D = 180 \degree](https://tex.z-dn.net/?f=m%20%5Cangle%20%5C%3A%20C%20%2B%20%20m%20%5Cangle%20%5C%3A%20D%20%3D%20180%20%5Cdegree)
OR
![m \angle \: B + m \angle \:C= 180 \degree](https://tex.z-dn.net/?f=m%20%5Cangle%20%5C%3A%20B%20%2B%20%20m%20%5Cangle%20%5C%3AC%3D%20180%20%5Cdegree)
![\implies41 \degree + m \angle \:C= 180 \degree](https://tex.z-dn.net/?f=%20%5Cimplies41%20%5Cdegree%20%2B%20%20m%20%5Cangle%20%5C%3AC%3D%20180%20%5Cdegree)
![\implies m\angle \:C= 180 \degree - 41 \degree = 139 \degree](https://tex.z-dn.net/?f=%5Cimplies%20m%5Cangle%20%5C%3AC%3D%20180%20%5Cdegree%20-%2041%20%5Cdegree%20%20%3D%20139%20%5Cdegree)
Is a binary operation on two vectors in three-dimensional space, and is denoted by the symbol. Given two linearly independent vectors a and b, the cross product, a × b, is a vector that is perpendicular to both a and b, and thus normal to the plane containing them.
