subtract the ones she got add the ones she gave away
The probability would be 1/4 for hearts 1/13 for the number card I think this is right sorry if it’s not
Let
The origin of coordinates the tree
r1 = vector position of the child 1.
r2 = vector position of the child 2
Child 1:
r1 = (12i + 12j)
Child 2:
r2 = (-18i + 11j)
The scalar product will be given by:
r1.r2 = ((12) * (- 18)) + ((12) * (11)) = - 84
The scalar product of their net displacements from the tree is -84m ^ 2
Answer:
RC1. 5
RC2. 8
RC3. a
RC4. 3
Step-by-step explanation:
So basically what you need to start with is the fact that the second triangle is 2 times larger than the first.
so,
8 = 8
C = 10
A = 6
---------------------------------------------------------------------
the next important part is that the opposite sides of the fraction, when multiplied are equal to each other.
( for example 1/2 = 2/4, because 1*4 = 4 and 2*2 = 4)
RC1. a/3 = C/_
substitute
6/3 = 10/_
3 * 10 = 30
6 * _ =30
30/6 = 5.
Rc2. 4c = 5_
4*10 = 5*_
40/5 = 8
RC3. 3c = 5*_
3*10 = 5*_
30/5 = 6
RC4. 4a = 8*_
4 * 6 = 8*_
24/8 = 3
good luck with your schoolwork/homework!

apologies in advance for incorrect answers or bad explanations.
Take the area of the triangle and multiply it by two because there's two triangles and do the same with the rectangle and then add them together
