3:05 for question 10
But i cant really make out number 12.
Well now, I don't know. Let's find out:
The factors of 35 are 1, 5, 7, and 35 .
The factors of 45 are 1, 3, 5, 9, 15, and 45 .
The common factors are: 1 and 5 .
The biggest one is 5 .

Answer:
$851.44
Step-by-step explanation:
The balance is given by the formula ...
A = Pe^(rt) . . . . principal P, interest rate r, t years
Using the given numbers, we find the balance to be ...
A = $600·e^(0.07·5) ≈ $851.44
Answer:
If c is greater than 0, than b can be all real numbers that do not equal 0.
Step-by-step explanation:
When looking at the value of c, we know that two factors of c always add up to create b. However, if c is positive, it gives us no indication of the size or sign of the factors and therefore b. Take the example of c = 100. In this instance, b could be -20 or 20. This is because factors of 100 can be -10/-10 or 10/10. We can do this with increasingly larger number, which allows us to assume that b can be both infinitely high or infinitely low.
Answer:
90 minutes or 1 hour 30 minutes
Step-by-step explanation:
Time taken to fill t is inversely proportional to number of pipes. We can express this as t ∝ 
where n is the number of pipes
We can also write this as t = 
where k is a constant
Using the data given 80 = 
(1)
For 6 pipes, if the time taken is T then
(2)
Dividing (2) by (1) gives
÷
÷ 
So
T = 
(multiplying both sides by 80
And this computes to 90 minutes or 1 hour 30 minutes
