snow_tiger [21]

Answer:

$1200.

Step-by-step explanation:

We have been given that Kiersten runs a website that helps people learn programming. Every month, Kiersten receives a subscription fee of $10 from each of the subscribers to her website.    

Let us find number of subscriber that will pay this month Kiersten for her online business.

Last month, the website had 100 subscribers. This month, 30 new members joined the website, and 10 members cancelled their subscription, therefore, number of subscriber this month will be 100+30-10=130-10=120 subscribers.  

To find amount that Kiersten will receive from online business we will multiply 10 by 120.  

\text{Kiersten will earn from online business}=120\cdot 10

\text{Kiersten will earn from online business}=1200

Therefore, Kiersten will earn $1200 from online business this month.

A line passes through the point (-8, 2) and has a slope of -1
Zanzabum

Answer:

y=-x-6

Step-by-step explanation:

Plug this into the equation y-y1=m(x-x1) where m is the slope. We know that it passes through (-8,2) so y1=2 and x1=-8. We also know that the slope is -1 so we can now fill in the equation. y-2=-1(x--8). We can change x--8 to x+8 so y-2=-1(x+8). Simplify this to get y-2=-x-8. You want to isolate y so you have to add 2 on both sides. y=-x-6. Therefore, the equation is y=-x-6.

An equilateral triangle has an apothem measuring 2.16 cm
Llana [10]

Answer:

d)   24.2 cm²

<em>Area of equilateral triangle  A = 24.22 cm²</em>

Step-by-step explanation:

<u><em>Step(i)</em></u>:-

<em> Perimeter of equilateral triangle  = 3 a</em>

Given  Perimeter of equilateral triangle  = 22.45 cm

   now   3 a = 22.45

  Dividing '3' on both sides,we get

             a = 7.48 cm

<u><em>Step(ii):</em></u>-

<em>Area of equilateral triangle</em>

<em>                                   </em>A = \frac{\sqrt{3} a^{2} }{4}<em></em>

<em>                                    </em>A = \frac{\sqrt{3} (7.48)^{2} }{4}<em></em>

<em>                                   A = 24.22 cm²</em>

<u><em>Conclusion</em></u><em>:-</em>

<em>Area of equilateral triangle  A = 24.22 cm²</em>
