find the circumference and the area of the circle with a diameter of 15ft

Answers

Answer:

Circumference is pi times diameter so that would equal 15 pi. The formula to find the area of a circle is A=pi * r^2 So you divide 15 by 2 to find the radius. r=7.5 Then you square it and multiply it by pi and get 56.25pi which is about equal to 176.715

A saleswoman earns 20% commision on all the merchandise that she sells. Last month she sold $900 worth of merchandise. How much commission (in dollars) did she earn last month?

Answers

Given:

Last month sales = $900

Rate of commission = 20%

To find:

How much commission (in dollars) did she earn last month?

Solution:

We have, 20% rate of commission. So, the commission for the last month is equal to 20% of last month sales $900.

[tex]\text{Commission}=\dfrac{20}{100}\times 900[/tex]

[tex]\text{Commission}=20\times 9[/tex]

[tex]\text{Commission}=180[/tex]

Therefore, the commission for the last month is $180.

Answer:

$60

Step-by-step explanation:

A garden measuring 8 feet by 12 feet will have a walkway around it. The walkway has
a uniform width, and the area covered by the garden and walkway is 192 square feet.
What is the width of the walkway?
O 3.5 feet
O 6 feet
O 2 feet
O 4 feet

Answers

Answer:

2 feet

Step-by-step explanation:

By solving a quadratic equation, we will see that the width of the walkway must be 2 ft.

How to get the width of the walkway?

Remember that the area of a rectangle of length L and width W is:

A = L*W

In this case, we know that the dimensions are:

Length = 8ftWidth = 12ft

Now, if we add a walkway of width x all around the garden, the new dimensions of the garden are:

Length = 8ft + 2xWidth = 12ft + 2x

Now with these dimensions, the area is 192 ft^2, then we can write:

192 ft^2 = (8ft + 2x)*(12ft + 2x)

Now we need to solve that for x:

192 ft^2 = 96ft^2 + 4x^2 + 40ft*x

0 = 96ft^2 - 192ft^2 + 4x^2 + 40ft*x

0 = 4x^2 + 40ft*x - 96ft^2

This is a quadratic equation, the solutions are given by Bhaskara's formula:

[tex]x = \frac{-(40ft) \pm \sqrt{(40ft)^2 - 4*4*(-96ft^2)} }{2*4} \\\\x = \frac{-(40ft) \pm 56ft }{8}[/tex]

Notice that we have two solutions, but we only care for the positive one, so we take:

x = (-40ft + 56ft)/8 = 2ft

So the width of the walkway must be 2ft.
