Answer:
If the complement of an angle is 25 degrees, then the measurement of the angle will be 65 degrees
Step-by-step explanation:
It takes 3 pumps 16 hours to empty a tank
Meaning it takes 48 hours for one pump by its self
So if there are 4 pumps
48/4 it would take them 12 hours
They would need to work 12 hours to do it in 1 day
Answer:
9x
9 is the coefficient
Step-by-step explanation:
5x + 4x
These are like terms (they both have the same variable (x))
5x + 4x = 9x
The coefficient is 9, since it's the number in front of a variable.
Hope this helped!
RSM can send 4 of its 18 teachers into a conference in 3060 ways.
Combinations are the various ways in which objects from a given set may be selected. Normally it is done without replacement, to form the subsets. Combinations are a way to find out the total outcomes of an event where the order of the outcomes does not matter.
Thus the Combination is the different selections of a given number of objects taken some or all at a time. For example, if we have two alphabets A and B, then there is only one way to select two items, we select both of them. For Combinations, k elements are selected from a set of n objects to produce subsets without bothering about ordering. Here Combinations BA and AB will be no longer distinct selections. Thus by eliminating such cases we get only 10 different possible groups, which are AB, AC, AD, AE, BC, BD, BE, CD, CE, and DE.
Thus RSM can send 4 of its 18 teachers into a conference = 18C
18C = 3060 ways
Thus RSM can send 4 of its 18 teachers into a conference in 3060 ways
