What single decimal multiplier would you use to increase by 18% followed by a<br> 12% decrease?
ValentinkaMS [17]

Answer:

The single decimal multiplier used to increase by 18% followed by a  12% decrease is 0.21.

Step-by-step explanation:

Let 'x' be the number

As first the number has to be increased by 18%

so

Step 1: write the percentage '18%' in decimal form

18% = 0.18    

Step 2: For percentage increases: add the decimal to 1

1 + 0.18 = 1.18    

Step 3: Multiply the number x by the multiplier, found in Step 2

x × 1.18 = 1.18x

<u><em>NEXT WE HAVE TO DECREASE 1.18x by 12%</em></u>

Apply the same method but with a number 1.18x

  • Write the percentage '12%' in decimal form

12% = 0.12

  • For percentage decreases: subtract the decimal to 1

1 - 0.18 = 0.18

  • Multiply the number 1.18x by the multiplier, found in Previous step

1.18x × 0.18 = 0.21x

Therefore, the single decimal multiplier used to increase by 18% followed by a  12% decrease is 0.21.

So, put your "x's" together first and then your intercepts. That should answer your question :)

Haruka owns an umbrella factory. The revenue, RRR, she makes from selling nnn umbrellas is given by the function R(n)=18nR(n)=18
Levart [38]

<u>Answer:</u>

E(n) = n + 5


<u>Explanation:</u>

The profit is the difference between the amount of money received as a revenue and the amount of money spent as expenses.

<u>This means that:</u>

Profit = Revenue - Expenses


<u>Rearrange the formula to solve for the expenses, we get:</u>

Expenses = Revenue - Profit


<u>We are given that: </u>

Revenue = R(n) = 18n

Profit = P(n) = 17n - 5


<u>Substitute in the above formula to get the formula for expenses as follows:</u>

E(n) = R(n) - P(n)

E(n) = 18n - (17n-5)

E(n) = 18n - 17n + 5

E(n) = n + 5


Hope this helps :)

Which radian measure is equivalent to −15°? −9π/20 −12/π −20π/9 −π/12
Reika [66]

Answer:

<h3>-π/12</h3>

Step-by-step explanation:

Which radian measure is equivalent to −15°? −9π/20 −12/π −20π/9 −π/12

180 degrees = πrad

-15 degrees = x

Cross multiply

180x = -15π

x = -15π/180

x = -π/12

Hence the value of -15 degrees in radians is -π/12
