Which of these numbers are exactly divisible by 9? 107,513,944,126,80

Answers

Answer 1

Answer:
513 and 126 both are. (The question doesn't say
that there's only one of them in the list.)

Here's an easy way to tell: (I don't know how or why it works,
but it works.)

You're looking at a big number, and you need to find out if it's
divisible by 9.
Here's the two-step process:
-- If it's going to be divisible by 9, then it has to be divisible by 3.
-- Find out whether it's divisible by 3. If it is, then ...
-- Find out whether it's divisible by 9.

Step 1:
Add up all the digits in the number. If that sum is divisible by 3,
then the original big number is too.

Example:
Is 549 divisible by 3 ?
Add up its digits: (5 + 4 + 9) = 18 .
Is 18 divisible by 3 ?
Yes. That tells you that 549 is divisible by 3 .
So it could be divisible by 9.

Step 2:
Take that same 18 and add up its digits.
(1 + 8) = 9.
9 is divisible by 3.
This tells you that the original big number ... 549 ... is also divisible by 9 .

a ski resort has 3 chair lifts each access to 6 ski trails. explain how you can find the number of possible outcomes when choosing a chair lift and a ski trail without making a list

Answers

Answer: Hello there!

in this problem, we have two things to choose, the chair lift and the ski trail, with 3 options for the chair lifts, and 6 options for the ski trails.

The total number of combinations is obtained by multiplying the number of options for each one of the things that we have to choose; in this case, it is 6*3 = 18 total combinations.

Multiply 3 times 6 and then you get 18 all of the possible outcomes

Which equation represents the graph of the linear function?A.
y = 4x + 4

B.
y = 4x − 4

C.
y = −4x + 4

D.
y = −4x − 4

Answers

By looking at the graph you can rule out choices C and D because the graph given to you is an increasing linear function and C and D represent functions with a decreasing or negative slope.

By looking at the picture the slop of the graph seems to be 4/1 (rise/run) so your slope is 4. And your y-intercept looks like its -4 so your answer is B
