What is the product of all positive divisors of $100$?

1 answer:

6 0

1,2,4,5,10,20,25,50,100 are all the positive divisors of 100. However, rather than straight up multiplying them in random order, I will multiply the opposite ends with each other (100*1, 2*50, 4*25, 5*20) and then multiply 10.
100*1=100
2*50=100
4*25=100
5*20=100
100*100*100*100*10= 1,000,000,000

Answer: 1,000,000,000

Answer: the system of equations are

x + y = 35

3x + 2y = 100

Step-by-step explanation:

Let x= the number of short answer questions.

Let y= the number of multiple choice questions.

Noah wants 35 questions on the exam. This means that

x + y = 35

He plans to mix short answer questions, worth 3 points, with multiple choice questions worth 2 points. This means that x short answer questions will give 3x points and y multiple choice questions will give 2y points

Since the exam is worth 100 points, then,

3x + 2y = 100 - - - - - - - -1

Substituting x = 35 - y into equation 1, it becomes

3(35 - y) + 2y = 100

105 - 3y + 2y = 100

y = 105 - 100 = 5

x = 35 - y = 35 - 5

x = 30
