The area of a circle is 4π ft². What is the circumference, in feet? Express your answer in terms of \piπ.
Answer:
4π ft.
Step-by-step explanation:
Area = π r^2 = 4π = π2^2
- so the radius is 2 ft,
and the circumfrence = 2 π r
= 2*π*2
= 4π ft.
The circumference of the circle is 4π feet.
What is a circle?A circle is a two-dimensional figure with a radius and circumference of 2pir.
The area of a circle is πr².
We have,
The formula for the area A of a circle with radius r is given by:
A = πr²
We are given that the area of the circle is 4π ft², so we can set up the following equation:
4π = πr²
Dividing both sides by π, we get:
r² = 4
Taking the square root of both sides, we get:
r = 2
The circumference C of a circle with radius r is given by:
C = 2πr
Substituting r = 2, we get:
C = 2π(2) = 4π
Therefore,
The circumference of the circle is 4π feet.

The diagram shows triangle ABC. Angel ABC is NOT an obtuse angle. Find the greatest value of x. You must show all your working. (Your final line should say ‘Greatest value of x is..’)
First, an angle in a triangle is always less than 180.
An obtuse angle is defined to be greater than a right angle, but less than 180. Since angle ABC is not an obtuse angle, its measurement must be 90 degrees or less.
Angle ABC = x + 3x + 30 = 4x + 30
Since we want x to has its greatest value, angle ABC must also have its greatest value ( -> 90)
Now, we find x : (90-30)/4 = 15
So, the greatest value of x is 15. (recheck : 15 + 15 x 3 + 30 = 90)

Step-by-step explanation:
If you subtract the number of brownies that Brittany's brother will eat, you will have 9 remaining brownies. So, that means 9 out of the original 12 brownies will be left, or 9/12. Also, you can simplify the fraction. Both 9 and 12 can be divided by 3.
9/12 divided by 3/3 equals 3/4. 3/4 is the fraction in it's simplest form.
So, 9/12 (or 3/4) of the brownies are left.

Answer:
18 kilometers
Step-by-step explanation:
if you know the perimeter, then all you have to do is add up what you have, 10+7=17 and then subtract it giving you the bits that you dont know, so 35-17=18 kilometers.
Answer:
s = 9 Km
Step-by-step explanation:
the perimeter is the sum of the 4 sides
given perimeter = 35 , then
10 + 7 + s + s = 35
17 + 2s = 35 ( subtract 17 from both sides )
2s = 18 ( divide both sides by 2 )
s = 9 Km

Have you ever seen a photo online that did not seem to have the colors right? Perhaps the colors looked unnatural or not appropriate for the subject of the photo. Describe such a photo and what you think was wrong with it in terms of color. How did this photo with poor color values make you feel about the website it was on? How important do you think getting the color right is for images online?
Write three to five sentences that answer these questions. You should thoroughly explain every statement you make in your response. If possible, include a link to the photograph you are describing.
Answer:
Yes, I have before. The colors were pretty natural, but they didn't quite fit with the actual picture. It was a street with blue vintage contrast, and it had a rotting apple core. It was wrong because blue street didn't feel that normal and was an inaccurate portrayal because it didn't fit the apple core and all. The website actually was a website with "bad" photos, so I understood. I think it is very important to accurately convey meaning, tone, and much more.

1. At what prices would Dairy Queen earn zero profit?
2. How should Dairy Queen price their blizzards to maximize profits?
3. What is their estimated maximum profit?
4. Sketch a graph and make sure to label the x and y axis.
The function P(x) = -65(x - 4)² + 1000 of Dairy queen is an illustration of quadratic functions
Dairy queen should price their blizzards at $4, and the estimated maximum profit is $1000
The price that gives zero profitThe function is given as:
P(x) = -65(x - 4)² + 1000
At zero profit, P(x) = 0
So, we have:
-65(x - 4)² + 1000 = 0
From the graph of the function (see attachment), we have:
x = 0.078 and x = 7.922
Hence, the prices that give zero profit are 0.078 and 7.922
How to maximize profits?To maximize profit, Dairy Queen should their blizzards at a price that yields maximum profit
The estimated maximum profitWe have:
P(x) = -65(x - 4)² + 1000
A quadratic function is represented as:
P(x) = a(x - h)² + k
Where:
Vertex = (h,k)
So, we have:
h = 4 and k = 1000

Let the amount of pecans is x pounds and cashew is y pounds.
The inequalities according to the question are:
x + y ≥ 36x + 8y ≤ 24The solution of the system is attached as a graph below.
Possible combinations are:
(2, 1) or (1, 2)Answer:
3 pounds of pecans and 0.5 pound of cashews
2.5 pounds of pecans and 1 pound of cashews
Step-by-step explanation:
Given information:
Malik can spend no more than $24 to buy pecans and cashews.Malik wants to buy at least 3 pounds of nuts.Cost of pecans = $6 per poundCost of cashews = $8 per poundDefine the variables:
Let x = number of pounds of pecans Malik can buy
Let y = number of pounds of cashews Malik can buy
Create a system of inequalities from the given information:
6x + 8y ≤ 24x + y ≥ 3Graph the inequalities (see attached)
The possible solutions are any points enclosed by the shaded area where x > 0 and y > 0.
Therefore, two possible combinations are:

At the same time, his sister leaves their house and starts biking to school at a speed of 12 mph. how far from home is their school if they meet in 10 minutes
We will see that the distance between the home and the school is 0.5 miles.
How far from home is their school?We know that they meet in school after 10 minutes.
So, the distance from home to school will be equal to the slowest of the speeds times 10 minutes (we assume that the faster one arrives at school earlier than in 10 minutes).
This will be:
3 miles per hour *10 minutes.
Note that the units are different, so we write 10 minutes in hours.
1 hour = 60 min.
(1/ 60) hour/min = 1.
Then:
10 min = 10 min*(1/ 60) hour/min = 0.167 hours.
Now we can find the distance to their school as:
D = 3 mi/h*0.167 h = 0.5 miles.

The original price is $125. The sale price is $81.25. How much was the discount as a percent?
Answer: 35%
Step-by-step explanation:
Start by subtracting the original price by the sale price.
125-81.25=43.75
Now divide that amount by the original price.
[tex]\frac{43.75}{125} =0.35[/tex]
Multiply that value by 100 for the answer
0.35×100=35
35%
Answer:
Discount Percent = 35.00 %
Step-by-step explanation:
125-81.25=43.75 actual discount
43.75/125 = 0.35 actual discount / original
0.35 as percentage = 35%

The surface area of a cylinder is about 155.83 square feet. The height of the cylinder is 3 times the radius. What are the height and the diameter of the cylinder, to the nearest hundredth of a foot?
The radius is approximately___ feet and the height is approximately___feet.
The diameter and height of the cylinder are 4.98ft and 7.47 feet respectively
How to calculate the surface area of a cylinderThe formula for calculating the surface area of a cylinder is expressed as:
S = 2πr(r+h)
where
r is the radius
h is the height = 3r
Substitute into the expression to have:
S = 2πr(r+3r)
S = 2πr(4r)
S = 8πr²
155.83 = 8πr²
r = 2.49feet
Since h = 3r
h = 3(2.49)
h = 7.47 feet
Hence the diameter and height of the cylinder are 4.98ft and 7.47 feet respectively
