Fourty mins after 4:40 is fourty mins before…

marissa [1.9K]

Answer:

B. 6:00

Step-by-step explanation:

There are 60 minutes in one hour.

To calculate 40 minutes after 4:40, separate 40 minutes into two lots of 20 minutes.

⇒ 4:40 + 20 minutes = 5:00

⇒ 5:00 + 20 minutes = 5:20

Therefore, 40 minutes after 4:40 is 5:20

To calculate the time that 5:20 is 40 minutes before, add 40 minutes to 5:20

⇒ 5:20 + 40 minutes = 6:00

Therefore, the solution is option B. 6:00

How many different committees can be formed from 6 teachers and 37 students if the committee consists of 4 teachers and 4 stude

Anna [14]

Answer:

The committee of 8 members can be selected in 990,675 different ways.

Step-by-step explanation:

The order in which the teachers and the students are chosen is not important, which means that the combinations formula is used to solve this question.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In this question:

4 teachers from a set of 6.

4 students from a set of 37.

Then

$T = C_{6,4}C_{37,4} = \frac{6!}{4!2!} \times \frac{37!}{4!33!} = 990675$

The committee of 8 members can be selected in 990,675 different ways.
