The product of two even numbers is even.
Let m and n be any integers so that 2m and 2k are two even numbers.
The product is 2m(2k) = 2(2mk), which is even.
Things to think about:
Why didn’t I just show you by using any two even numbers like the number 4 and the number 26?
Why did I change from "m" to "k" ? Are they really different numbers or could they be the same?
Why did I specifically say that m and k were integers?
The product of two odd numbers is an odd number.
Let m and k be any integers. This means that 2m+1 and 2k+1 are odd numbers.
The product is 4mk + 2m + 2k + 1 (hint: I used FOIL) which can be written as
2 ( 2mk + m + k ) + 1 which is an odd number.
Answer:
the distance of the rope between boat and dock is 30
Step-by-step explanation:
to get the distance between the rope and the dock we use tan 40 because we have the opposite as 25.17ft
tan 40 = opposite/adjacent
0.839 = 25.17/a
cross multiply
0.839a= 25.17
a = 25.17/0.839 = 30 ft
Answer:
8 hours
Step-by-step explanation:
Job v starts at time 0 and completes at time 3.
Job w starts at time 1 and completes at time 4.
Job x starts at time 4 and completes at time 8.
Job y starts at time 8 and completes at time 10.
Job z starts at time 10 and completes at time 15.
The average completion time is (3 +4 +8 +10 +15)/5 = 8 . . . hours.
_____
<em>Comment on the schedule</em>
Jobs v and x are the only ones completed by the time due. The latest is 8 hours late. If they are scheduled in order of due time, jobs v, w, and y can be completed by the due time; the others will be 4 and 6 hours late.
Answer:
the price of the ticket multiplied by thirteen is your answer
Step-by-step explanation:
750 / 9 = 83.333333
83.33333 * 24 = 2000
100 / 6 = 16.66666667
16.6666667 * 24 = 400
2000 - 400 = 1600 gallons more than the kidney
