8.9+9.5r=−100.445 what is r? first will be marked brainliest!

Mathematics
2 answers:
dexar [7]2 years ago

Answer:

Step-by-step explanation:

Begin by isolating the term with the r in it. Do that by subtracting 8.9 from both sides:

9.5r = -110.445 - 8.9 and

9.5r = -119.345  Divide both sides by 9.5 to get

r = -119.345/9.5 and

r = 12.56263158 (or you could leave it as a fraction)

The answer is 11.51.


8.9+9.5r=-100.445, so we have to remove the 8.9 by subtracting it from both sides.

9.5r=-109.345, but now we have to get r by itself, so we have to divide both sides by 9.5

r=-11.51

Locate the mean of 2046,971,3113,and 1850.
Debora [2.8K]
To find the mean, you have to add all the numbers then divide it by how many numbers there are.

In this case, you'll need to add all those numbers and divide it by 4.
2046+971+3113+1850=7980\\7980\div4=1995

The mean is 1995.

The domain of f(x) is the set of all real values except 7, and the domain of g(x) is the set of all real values except -3. Which
Maurinko [17]

Answer:

The option is: <em>all real values except x = 7 and the x for which f(x) = -3</em>

Step-by-step explanation:

As the domain of f(x) is the set of all real values except 7. So it can be written as follows:

              Domain of f(x) = { x ∈ R | x ≠ 7}

As the domain of g(x) is the set of all real values except -3. So it can be written as follows:

              Domain of g(x) = { x ∈ R | x ≠ -3}

It is a common rule that the domain of a composite function (gºf)(x) will be the set of those input x in the domain of f for which f(x) is in the domain of g.

So, the option is: <em>all real values except x = 7 and the x for which f(x) = -3</em>

Keywords:  domain, composite function

1.2million users of social media via mobile devices were added each day. How many users added on an average each second
Pachacha [2.7K]

Answer: 14 new users are added per second

Step-by-step explanation:

1,200,000/24 = 50000

50000/60 = 833.333333333

833.333333333/60 = 13.8888888889

then round because it said on average

so if we round 13.8888888889 we get 14

so on average 14 new users are added per second.
