The circumference of a circular park is approximately 18 feet. What is the approximate area inside the circular park?
Answer:
25.685 square feet.
Step-by-step explanation:
Circumference = 2 * π * radius
From this, we can derive the formula for the radius:
radius = Circumference / (2 * π)
Let's substitute the value of the circumference and calculate the approximate radius:
radius = 18 / (2 * π)
radius ≈ 18 / (2 * 3.14159)
radius ≈ 2.865 feet
Now that we have the approximate radius, we can calculate the area:
Area ≈ π * radius²
Area ≈ 3.14159 * (2.865)²
Area ≈ 3.14159 * 8.193225
Area ≈ 25.685 square feet
Therefore, the approximate area inside the circular park is approximately 25.685 square feet.

Step-by-step explanation:
the ratio of the number of oranges to apples to bananas is 8:5:2. if there are 120 fruits in total, how many bananas are there
Answer:
Step-by-step explanation:
To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.
Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.
The sum of the parts in the ratio is 8x + 5x + 2x = 15x.
We know that the total number of fruits is 120. Therefore, we can set up the following equation:
15x = 120
To solve for x, we divide both sides of the equation by 15:
x = 120 / 15
x = 8
Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:
Number of bananas = 2x = 2 * 8 = 16
So, there are 16 bananas in total.
We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.
A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?
2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100
The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:
2/8 = j/18
This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:
2/8 = j/18
218 = 8j
36 = 8*j
j = 36/8
j = 4.5
Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.
Answer:
2 over 8 equals j over 18Step-by-step explanation
2 over 8 equals j over 18
This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.
So, the correct proportion is:
2 over 8 equals j over 18

A rectangular garden has a walkway around it. Find the area of the walkway.
Answer:
Step-by-step explanation:
Im no expert but you would need information on the length and width of the rectangular garden and walkway. To figure this out you would need the information on the width of the walkway and length and width of the rectangle.
Let's pretend a rectangle has a width of 4 and length of 6. I would do 4x6. Then for the walkway lets pretend the width is 3. Since the we know the length of the rectangle is 6 and the width 4, I would do 2(6x3)+2(4x3).

\(Simplify (2x-7)(x+3)-(-3x^{2} -4)\)
Answer:
\(5x^2 - x - 17\)
Step-by-step explanation:
Distribute the terms inside the first set of parentheses:
\((2x - 7)(x + 3) = 2x^2 + 6x - 7x - 21\)
Combine like terms:
\(= 2x^2 - x - 21\)
Simplify by adding the second part:
\(2x^2 - x - 21 - (-3x^2 - 4)\)
Subtracting a negative is the same as adding the positive equivalent:
\(= 2x^2 - x - 21 + 3x^2 + 4\)
Combine like terms:
\(= 5x^2 - x - 17\)
(2x-7)(x+3)-(-3x^[2] - 4)
====
5x^[2] -x -17
To begin simplifying this expression, we will foil the first half of it:
(2x-7)(x+3)
2x*x + 2x*3 - 7*x - 7*3
2x^[2] + 6x - 7x - 21
With this, we combine like terms:
2x^[2]-x-21
We now have
2x^[2]-x-21-(-3x^[2]-4)
We can now do the binomial distribution in the second half of the expression. Remember, the - sign in front of the parentheses means we are negating everything inside. In other words, we are multiplying -1 by everything inside the parentheses. Following this:
-(-3x^[2]-4) becomes
-1*-3x^[2] + -1*-4 = 3x^[2]+4
We have now simplified the first and second half of our expression, so we have:
2x^[2]-x-21+3x^[2]+4
And combining like terms we get
2x^[2]+3x^[2]-x-21+4 =
5x^[2] -x -17
We can use the quadratic expression to determine if the trinomial can be factored evenly, but it cannot so we have our final simplifed expression!
