Mass=5.6
Find this by plugging your values into the density formula and solving for M.
Answer:
Step-by-step explanation:
(A-B)U (A∩B) [ We know that difference of A and B is A∩B')
A∩B')U(A∩B)
A∩(B'UB) (Using Distributive law)
A∩(U) [ Union of a set and its complement is always a universal set]
A Hence proved
3(4) - 2 is the proper format. 3(4) - 2 is equal to 10.
Mia walked 7km/h so after 1 hour, she is 7 km north of the house of Julia
Samantha walked 11km/h so after 1 hour, she is 11 km west of the house of Julia.
The points where Mia and Samantha are after 1 hour , and the house of Julia form a right triangle with sides 7 and 11 km. The distance between the girls, is the hypotenuse of his triangle.
by the pythagorean theorem:

Answer: 13 km
