Using the Fundamental Counting Theorem, it is found that 60 different possible student council teams could be elected from these students.

<h3>What is the Fundamental Counting Theorem?</h3>

It is a theorem that states that if there are n things, each with n_1, n_2, \cdots, n_n ways to be done, each thing independent of the other, the number of ways they can be done is:

N = n_1 \times n_2 \times \cdots \times n_n

Considering the number of options for president, vice president, treasurer and secretary the parameters are:

n1 = 5, n2 = 2, n3 = 2, n4 = 3.

Hence the number of different teams is:

N = 5 x 2 x 2 x 3 = 60.

In One hour a bakery sold five muffins and nine bagels for a total of $25.50 the next hour the bakery sold three muffins and 12
RoseWind [281]

Answer:

Option A is the correct choice.

Step-by-step explanation:  

We have been given the system of linear equations written by Draco. We are asked to find Draco's error.

Let us form a system of equations using our given information.

Let m represent the price of one muffin and b represent the cost of one bagel.

We are told that in one hour a bakery sold five muffins and nine bagels for a total of $25.50. We can represent this information in an equation as:

5m+9b=25.50...(1)

The next hour the bakery sold three muffins and 12 bagels for a total of $28.50. We can represent this information in an equation as:

3m+12b=28.50...(2)

Now let us see system of equations written by Draco.

5m+9b=28.50

3m+12b=25.50

We can see that Draco has set the price of 5 muffins and 9 bagels equal to $28.50, which is the price of 3 muffins and 12 bagels.

Therefore, Draco should have set the first equation equal to 25.50 and the second equation equal to 28.50. The correct choice is option A.

DochEvi [55]

Answer:

D

Step-by-step explanation:

1+3(6-3n)= -6-4n

1+18-9n= -6-4n

1+18+6= 9n-4n

25=5n

25/5=n

5=n

All the fudge machines at a chocolate factory work at the same rate. Six machines working simultaneously can complete a big orde
madreJ [45]

Answer:

11 hours

Step-by-step explanation:

The number of machines working in the factory = 6 machines

Decreasing it by a factor of 2 =

6 ÷ 2 = 3 machines.

Hence:

If 6 machines complete a big order = 22 hours

3 machines = x hours

Cross Multiply

6 machines × x hours = 22 hours × 3 machines

x hours = 22 hours × 3/6

= 66/6

x = 11 hours

Therefoee, it would take 11 hours to fill the order if the number of working machines decreased by factor of 2.
