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.

A factory makes candles. Each candle is in the shape of a triangular prism, as shown below. If the factory used 15,552 cm 3 of wax, how many candles did the factory make?
Answer:
72 candles
Step-by-step explanation:
15 552 ÷ 27×8
=72
In order to find how many candles factory has made, we need to first find out how much volume of wax is required to make a single candle of the shape triangular prism.
So, first we need to find out the volume of triangular prism which is given by multiplying the area of the triangle and the length of the triangular prism.
From the figure, we can notice that :
Base of the triangle = 9 cm
Height of the triangle = 6 cm
We know that : Area of a triangle is given by : 1/2 × Base × Height
⇒ Area of the triangle = 1/2 × 9 × 6 = 27 cm²
⇒ Volume of the triangular prism = Area of the triangle × Length
From the figure, we can notice that :
Length of the triangular prism = 8 cm
⇒ Volume of the triangular prism = 27 × 8 = 216 cm³
It means : The factory needs 216 cm³ volume of wax to make one candle
Given : The factory used 15552 cm³ of wax
\(\implies \sf{\textsf{Total number of candles factory made} = \dfrac{15552}{216}}\)
\(\implies \sf{\textsf{Total number of candles factory made} = 72}\)

Answer: y = -1/4x - 6
Step-by-step explanation: the slope is -1/4 because slope = rise/run, the rise is 1, and the run is 4 and the slope is negative. the y intercept is -6 because it passes through -6 at the y axis.
Answer:
-1/4x + -6
Step-by-step explanation:
The slope is -1/4 because slope = \(\frac{rise}{run}\),
So:
-\(\frac{1}{4}\) is the slope, also is negative.
The y intercept is -6 because it passes through -6 at the y axis.
( I also checked it on khan Academy and it was correct)

Answer:
25
Step-by-step explanation:
4a +12 -2c + c
4( ) + 12 - 2( ) + ( )
4(4) + 12 - 2(3) + 3
16 + 12 - 6 + 3
28 - 6 + 3
22 + 3
25
Helping in the name of Jesus.
Therefore, 4a + 12 - 2c + c = 25
Step-by-step explanation:a = 4
c = 3
Swap letters for numbers:4a + 12 - 2c + c
(4)(4) + 12 - (2)(3) + 3
16 + 12 - (2)(3) + 3
28 - (2)(3) + 3
28 - 6 + 3
22 + 3 = 25
Draw a conclusion:
Hence your answer is:4a + 12 - 2c + c = 25

Addison purchased train tickets to go visit her family in New York. The original cost of the train ticket is $256.00 The train company is offering 15% off the cost of the ticket. They also charge a 7.65% sales tax on the discounted price.
What is the final cost of her train ticket, including tax?
Answer:
$234.25
Step-by-step explanation:
15% of 256 is 38.40
256-38.40+217.60
7.65% of 217.60 is 16.65
16.65+217.60=234.25

Some students recorded how many minutes they spent on the phone in one day. They put the results in a Stem-and-Leaf Plot.
What is the mean number of minutes spent on the phone?
Explanation:
The data from the stem-and-leaf plot is:
10,
24,25,26,
30,30,32,33,
40,45,46
Add up those values
10+24+25+26+30+30+32+33+40+45+46 = 341
Then divide over n = 11 which is the sample size.
341/11 = 31 is the arithmetic mean.
Answer:
341/11 = 31 is the arithmetic mean.
Step-by-step explanation:
Point A, located at (5, -4) is reflected in the y-axis, resulting in the location of point A'. Which of the following statements is true?
Point A' is located at (-5,-4)
Point A' is located at (-5,4)
Point A is located at (4,5)
Point A' is located at (-4,5)
The correct answer is Point A' is located at (-5, -4).
When a point is reflected in the y-axis, its x-coordinate is negated and its y-coordinate remains the same. Therefore, the x-coordinate of point A changes from +5 to -5, and the y-coordinate remains -4. Hence, the coordinates of A' are (-5, -4).

27
30
35
15
Answer:
30 ft

Answer:
y = 6x
Step-by-step explanation:
So for this we simply find a x and y coordinate (ex. (10, 60))
Since we see that the y coordinate is 6 times of the x coordinate, we know that the equation for this proportional relationship is y = 6x.

The dot plot shows the number of movies 15 people watched in a month: Dot plot labeled Number of Movies Seen shows 2 dots over 0, 2 dots over 7, 3 dot over 8, 3 dots over 9, and 5 dots over 10. Is the median or the mean a better center for this data and why? (1 point) Mean; because the data is normally distributed and has an outlier Mean; because the data clusters on the right and is not symmetric Median; because the data is normally distributed and has an outlier Median; because the data clusters on the right and is not symmetric
Answer:Median; because the data is not symmetric and there are outliers.
Step-by-step explanation:We know that a median is a central tendency of a data and it best represents the given data set.
From the given information we see that the data is skewed to the right since most of the data points takes the higher value and the data is not symmetric as it is skewed.
Hence, last option is the correct answer.
