Answer:
44
Step-by-step explanation:
10 x 3 = 30
8 + 6 =14
30 + 14 = 44
Answer:
0.343
Step-by-step explanation:
First, find the different ways one can chose a professor or instructor. In this case, there are 8 professors and 4 instructors. So there are a total of 12 ways you can choose a professor or instructor.
Second, you want to find the different ways you can choose any member of the faculty. In this example, since you are only choosing one person, then you just find the total number of people in the faculty, which is 8 + 11 + 12 + 4 = 35.
Third, all you do is divide the different ways you can get a professor or instructor by the total different ways you can choose. So it's 12/35, or 0.343.
-(5v5)^3 (use exponent rules)
-125x5v5 (calculate the product)
=-625v5 (pretend the v is a square root sign)
If B is midpoint of AC, then AB = BC and AC = AB + BC = 2AB
AC = 8x - 20, AB = 3x - 1
substitute
8x - 20 = 2(3x - 1)
8x - 20 = 6x - 2 |+20
8x = 6x + 18 |-6x
2x = 18 |:2
x = 9
BC = 3x - 1 → BC = 3(9) - 1 = 27 - 1 = 26
Answer: BC = 26
Its c because 11 x 11 = 121 and 12 x 12 = 144 and c is in the middle of them
