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

PART B write an equation to model the temperature in Baltimore on this day
Answer:
See below for answers and explanations
Step-by-step explanation:
A) The midline would be the average of the high and low temperatures, therefore d=(44+26)/2=70/2=35. The amplitude would be the distance from the high and low temperatures to the midline. Since 44-35=9 and 35-26=9, then the amplitude is a=9.
B) The equation would be [tex]T=9sin(\frac{\pi}{12}x)+35[/tex]

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
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 = 12ftNow, if we add a walkway of width x all around the garden, the new dimensions of the garden are:
Length = 8ft + 2xWidth = 12ft + 2xNow 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.

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?
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.

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For Example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
A seal has 1,500 nerve per whisker.
That is 10 times as many as a rat has.
So, the number of nerve per whisker does a rat have
= 1500/ 10
= 150 nerve
