Anarel [89]

Given: julianne  total startup cost = $52000

Operating cost per day =$680

Earn money from her lesson fee per day = $960

Find out the inequality of situation

Given d be the number of days

To proof: julianne spends on operating cost in d day = $680d

julianne earn from lesson fee in d day  = $960d

Total profit in d day = 960d-680d

Part A) Total profit should be greater than 52000. Because this is startup investment.

According to question inequality becomes

960d-680d\geq52000

Part B) Now solve for d

280d\geq 52000

d\geq 185.7

After 186 days, Julianne will get profit from dance studio.

17% of what number is 3.4
saw5 [17]

Answer:

20

Step-by-step explanation:

We already have our first value 3.4 and the second value 17. Let's assume the unknown value is Y which answer we will find out.

As we have all the required values we need, Now we can put them in a simple mathematical formula as below:

Step 1 ---> 3.4 = 17% × Y

Step 2 ---> 3.4 = 17/100 × Y

Multiplying both sides by 100 and dividing both sides of the equation by 17 we will arrive at:

Step 3 ---> Y = 3.4 × 100/17

Step 4 ---> Y = 3.4 × 100 ÷ 17

Step 5 ---> Y = 20

Finally, we have found the value of Y which is 20 and that is our answer.

<h3><u>*You can easily calculate 3.4 is 17 percent of what number by using any regular calculator, simply enter 3.4 × 100 ÷ 17 and you will get your answer which is 20*</u></h3>

Natalie is completing construction of an equilateral triangle inscribed in a circle, as shown below. What should be the next ste
mixas84 [53]

The next step she should take is to draw arcs above and or below line AB to show where the triangles sides meet.

<h3>Steps in construction of an equilateral triangle</h3>

The steps involved in the construction of an a equilateral triangle are:

  • Place the compass point on A and measure the distance to point B
  • Swing an arc of this size above or below of the segment.
  • Do not change the span on the compass
  • Then place the compass point on B and swing the same arc, intersecting with the first arc
  • Label the point of intersection as the third vertex of the equilateral triangle.

Thus, the next step she should take is to draw arcs above and or below line AB to show where the triangles sides meet.
