Answer:
The number of ways of selection of 3 items taking 2 at a time in addition to the possible ways in which each girl selects the same style is 9 different ways. Since the list contains 9 different ways in which each of them can select a style, the list is complete.
Step-by-step explanation:
Here we have the number of ways the available styles can be arranged between each girl is given by the number of permutation of 3 items, taking two at a time plus the number of possible selections where both of them select the same style as follows
We note that the formula for permutation is
P =
Therefore ₃P₂ = = 6 different ways
The number of possible selections where both of them select the same style is given by
(T, T), (s, s), (L, L) = 3 different ways
Total number of ways = 6 + 3 = 9 ways
Number of different ways available in the list = 9 ways
Therefore the list is complete
Let angle HAC = A, then
cos A = 24/25 = 0.96
A = cos^-1(0.96) = 16.26
Answer:
28.26
Step-by-step explanation:
To find the area of a circle you take pi times the radius squared ()
And to find the radius you divide the diameter by two.
Answer:
Yes.
Step-by-step explanation:
Yes, the two triangles are identical. It is commonly known that the angles of a triangle equal to 180 degrees in total. Even though the triangles are shown at different angles, their angle values are the same. By this, I mean that angle values of 70° and 95° are seen in both diagrams. This means that the last angle for both triangles will also be the same.
Hope this was helpful.
I would say just round it up to 25.
