Answer:
Step-by-step explanation:
<h3><u>Question 6</u></h3>
To find the greatest common factor (GCF), first list the prime factors of each number:
- 42 = 2 × 3 × 7
- 60 = 2 × 2 × 3 × 5
42 and 60 share one 2 and one 3 in common.
Multiply them together to get the GCF: 2 × 3 = 6.
Therefore, 6 is the GCF of 42 and 60.
Divide the numerator and the denominator by the found GCF:
<h3><u>Question 7</u></h3>
To find the greatest common factor (GCF), first list the prime factors of each number:
- 80 = 2 × 2 × 2 × 2 × 5
- 272 = 2 × 2 × 2 × 2 × 17
80 and 272 share four 2s in common.
Multiply them together to get the GCF: 2 × 2 × 2 × 2 = 16.
Therefore, 16 is the GCF of 80 and 272.
Divide the numerator and the denominator by the found GCF:
Answer: Each student checked out 164 books during the school year
Step-by-step explanation:
so to begin we need to add the total of students together so 17+15=32
Now we need to divide the amount of book by the amount of students
5,248 divided by 32= 164
So each student checked out 164 books during the school year
Hope this helped have a great day :)
F * g means exactly that.
Which is that you should multiply the definitions of the functions.
(x+7)(1/x-13) = x/x-13 + 7/x-13 = x+7/x-13
x+7/x-13
The domain of this function, is x<13 and x>13.
But not 13. Because 13-13 = 0
And it is not legal to divide a number by 0.
Hence, f*g(13) is not defined.
Pretty sure the correct answer is 19 :))
16 I believe not 100% sure though
