n(A-B) denotes elements which are in A but not in B
n(Au B) denotes elements in A and B
n(AnB) denotes elements that are common in A and B
Now I will add one more set
n(B-A) which denotes elements in B but not in A
So, n(AuB) = n(A-B) + n( B-A) +n(AnB)
70 = 18 +n(B-A) + 25
70 = 43 + n(B-A)
n(B-A) = 70-43
n(B-A) = 27
So, n(B) = n( B-A) + n( AnB)
= 27+25
= 52
The answer is Two students are the same age but have different heights. Hope this helps!
The formula is
A=p e^rt
A future value 1649
P present value 100
R interest rate?
T time 10 years
E constant
Solve the formula for r
R=[log (A/p)÷log (e)]÷t
R=(log(1,649÷100)÷log(e))÷10
R=0.28×100
R=28%
Answer:
the answer is 16ft
step-by-step explanation:
in order to make a triangle with non-zero area, the sum of the shorter two sides must be greater than the longest side.
here, 4 + 4 > 7, so the lengths can form a triangle.

To get a full answer we would need the diagram but to solve it I would find the distances between her house and school and add that to the distance from her school to her work then from her work home if Thier isn't information for her distance from work to her home I would double the amount that she already went
