Solve the formula for the specified variable N=(1/6)rm what is r

Mathematics

Virty [35]4 years ago

Answer:

r = \frac{6N}{m}

Step-by-step explanation:

Given an equation in terms of N on the left side and r, m variables on the right side.

Instead of N on left side we have to bring r on left side alone and other terms on right side to get formula for r.

For this multiply the given equation first by 6.

6N = rm

Now divide by m

r = \frac{6N}{m}

This is the formula for r in terms of N, m.

N=(1/6)rm

Solve for r

N = \frac{1}{6} rm

N = \frac{1}{6}*r*m

To remove the fraction 1/6, we multiply both side by reciprocal 6/1

N\frac{6}{1}= \frac{1}{6}*r*m\frac{6}{1}

6N = rm

Now divide by m on both sides

\frac{6N}{m}= \frac{r}{m}

\frac{6N}{m}= r

We solved for r

r = \frac{6N}{m}

4.4.3 Quiz: Independence
lbvjy [14]

Answer:

\frac{2}{15}

Step-by-step explanation:

<h2><u>Lesson : Probability</u></h2><h2><u></u></h2>
  • We have a bag with 4 white chips and 6 black chips
  • Question : What is the probability of randomly choosing a white chip, not replacing it, and then randomly choosing another white chip?

4 white and 6 black

4 + 6 = 10

Choosing the first white chip : \frac{2}{5}

Since we took one out , now

3 white chips , 6 black chips

3 + 6 = 9

Choosing another white chip : \frac{1}{3}

\frac{2}{5} * \frac{1}{3}

\frac{2}{15}

13. What are the x-intercepts of<br> y = 2x2 + 6x - 20?
Brilliant_brown [7]

Answer:

x = -5, 2

Step-by-step explanation:

The first step to factor the equation is removing any factors/like terms that all of the variables share.

In the equation y = 2x^2+6x-20, all numbers are multiples of 2, therefore you can factor out 2 from to equation

y = 2(\frac{2x^2}{2} + \frac{6x}{2} -\frac{20}{2})

y = 2(x^2+3x-10)

Next, you can factor the equation in the parenthesis. Since x^2 is not multiplied by anything, you know that the factors of x^2 must be x and x. Therefore, the two factors of -10 must add up to 3. The only two factors of -10/x that add up to 3 are 5 * -2.

The factors of the equation are then (2)(x+5)(x-2)

Lastly, set up only the factors containing a x to 0 in order to solve for x-intercept.

x+5 = 0; x= 0-5 ; x = -5

x - 2 = 0; x = 0 + 2; x = 2

Write 54 8 as a mixed number. Give your answer in its simplest form.
Finger [1]

Answer:

6 3/4

Step-by-step explanation:

to write 54/8 into the mixed number and in the simplest form

we first simpify 54/8 which is 27/4

to convert 27/4 into a mixed number we first see how many times does 4 goes into 27 with the remainder. 4 goes into 27 6 times with the remainder of 3.  4 goes into 27 6 times so, 6 will be the whole part 3 remainder will be the numerator and 4 will be the denominator. like 6\frac{3}{4}
