It is c, 2 -4 no solution
Answer:
They will sound together at 2pm
Step-by-step explanation:
Now, the first thing we need to calculate is , in how many minutes will the two gongs strike together.
To be able to do this, we need to calculate the least common multiple of the two numbers 24 and 40
The lowest common multiple between both is 120
This means that the two gongs will sound together at exactly 120 minutes
Now since 1 hour is 60 minutes, this means that 120 minutes will be = 120/60 = 2 hours
Since they both sounded together at 12 noon and the next time they will be sounding is next two hours, their sounding time will thus be 12 noon + 2 hours = 2 pm
Well first we need to know how many inches are in one foot which is 12 inches for every foot. So now we can take 108 inches / 12 because there are 12 inches to a foot and we need to convert inches to feet. Which gives us are end answer of 9 feet in 108 inches.
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:
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)!}](https://tex.z-dn.net/?f=C_%7Bn%2Cx%7D%20%3D%20%5Cfrac%7Bn%21%7D%7Bx%21%28n-x%29%21%7D)
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](https://tex.z-dn.net/?f=T%20%3D%20C_%7B6%2C4%7DC_%7B37%2C4%7D%20%3D%20%5Cfrac%7B6%21%7D%7B4%212%21%7D%20%5Ctimes%20%5Cfrac%7B37%21%7D%7B4%2133%21%7D%20%3D%20990675)
The committee of 8 members can be selected in 990,675 different ways.
Answer:
Multiplying/simplifying, it is x^2-100(found by the FOIL method)
Step-by-step explanation:
multiply the commons factors x times x is x squared
-10 times 10 is -100. Negative times positive is negative.
