Answer:
391
Step-by-step explanation:
8.5x46 = 391
Split it out and solve it !!
6(4a^2+11)- 13(3a-2a^2)-28
24a² + 66 - 39a +26a² - 28
50a² - 39a + 38
Total number of members = 12
Members to choose at a time = 2
This is a combination problem and we are to find the combination of 12 objects taken 2 at a time i.e. we are to find 12C2
12C2 = 66
So, there are 66 ways of selecting a president and vice president.
Therefore, the correct answer is option D
Hello from MrBillDoesMath!
Answer:
9 3/8
Discussion:
2 1/7 = 15/7
4 3/8 = 35/8
so the product
(2 1/7) * ( 4 3/8) =
15/7 * 35/8 =
15/7 * (7 * 5)/8 =
since 35 = 7*5. Cancel "7" in numerator\denominator to get
(15 * 5) / 8 =
75/8 =
9 3/8
Thank you,
