Which number is a factor of 15, but not a multiple of 3
2 answers:
We know that factors are numbers we can multiply together to get another number.
So 1 and 15 are factors of 15.
Also,
So 3 and 5 are factors of 15.
We have got 1, 3, 5, 15 all are factors of 15.
Multiple is a number that can be divided by another number without a remainder.
So we know that 3 is a multiple of 3, as and also 15 is a multiple of 3, as
.
But 1 and 5 are not multiples of 3.
We have got the required answer.
1 and 5 are factors of 15 but not multiples of 3.

<h3>Answer:</h3>
- C. (9x -1)(x +4) = 9x² +35x -4
- B. 480
- A. P(t) = 4(1.019)^t
Step-by-step explanation:
1. See the attachment for the filled-in diagram. Adding the contents of the figure gives the sum at the bottom, matching selection C.
2. If we let "d" represent the length of the second volyage, then the total length of the two voyages is ...
... (d+43) + d = 1003
... 2d = 960 . . . . . . . subtract 43
... d = 480 . . . . . . . . divide by 2
The second voyage lasted 480 days.
3. 1.9% - 1.9/100 = 0.019. Adding this fraction to the original means the original is multiplied by 1 +0.019 = 1.019. Doing this multiplication each year for t years means the multiplier is (1.019)^t.
Since the starting value (in 1975) is 4 (billion), the population t years after that is ...
... P(t) = 4(1.019)^t
