We have been given that the circular opening of an ice cream cone has a diameter of 7 centimeters. The height of the cone is 10 centimeters. We are asked to find the volume of the ice-cream cone.
We will use volume of cone formula to solve our given problem.
[tex]V=\frac{1}{3}\pi r^2 h[/tex], where
r = Radius of cone,
h = Height of cone.
We know that diameter is two times the radius, so radius will be half of diameter that is [tex]r=\frac{7}{2}[/tex].
[tex]V=\frac{1}{3}\pi\cdot (\frac{7}{2})^2\cdot 10[/tex]
[tex]V=\frac{1}{3}\pi\cdot (\frac{49}{4})\cdot 10[/tex]
[tex]V=128.2817[/tex]
[tex]V\approx 128.3[/tex]
Therefore, the volume of the cone would be approximately 128.3 cubic cm.
How many seconds will it take the object to reach the ground?
It will take approximately 5.05 seconds for the object to reach the ground.
Explanation:In order to determine how long it will take an object to reach the ground, we need to consider the height from which the object is dropped. Let's assume the height is 75.0 m.
The time it takes for an object to fall to the ground can be calculated using the equation t = sqrt(2h/g), where t is the time, h is the height, and g is the acceleration due to gravity (approximately 9.8 m/s^2).
Plugging in the values, t = sqrt(2 * 75.0 / 9.8) = sqrt(150 / 9.8) ≈ 5.05 seconds.
Therefore, it will take approximately 5.05 seconds for the object to reach the ground.

What is the equation of the line that passes through the point (-6,-6)(−6,−6) and has a slope of 2/3?
Answer:
y = 2/3 x -2
Step-by-step explanation:
We have a point and a slope
y = mx+b
The slope, m, = 2/3
y = 2/3 x+ b
The point is (-6,-6)
Substitute this into the equation to solve for b
-6 = 2/3 (-6) +b
-6 = -4+b
Add 4 to each side
-6+4 = -4+4+b
-2 =b
Substitute into the equation
y = 2/3 x+ b
y = 2/3 x -2
You have a tree in your yard 4 ft to the left of and 5 ft in front of the corner of your porch. A circular fence 3 ft in radius has its center at the tree. If the corner of your porch is the origin and forward is the positive y direction, what equation represents the circle formed by the fence in your yard?
Answer:
[tex](x+4)^2+(y-5)^2=9[/tex]
Step-by-step explanation:
If the corner of your porch is the origin
4 ft to the left, x=-45 ft in front, y=5The tree's location is at (-4,5).
A circular fence 3 ft in radius has its center at the tree(-4,5).We want to determine the equation of a circle with center (-4,5) and radius 3 ft.
The equation of a circle center (h,k) with a radius of r is given as:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
(h,k)=(-4,5), r=3
The equation formed by the fence therefore is:
[tex](x-(-4))^2+(y-5)^2=3^2\\\\$Simplifying we obtain:\\\\(x+4)^2+(y-5)^2=9[/tex]

Create a histogram to represent the data. Which statement is most likely true about the mean and the median of the data?
The histogram is right-skewed, so the mean is less than the median.
The histogram is right-skewed, so the mean is greater than the median.
The histogram is left-skewed, so the mean is less than the median.
The histogram is left-skewed, so the mean is greater than the median.
Answer:
The histogram is right-skewed, so the mean is greater than the median.
Step-by-step explanation:
The true statement about the mean and the median of the data is that: B. histogram is right-skewed, so the mean is greater than the median.
What is a histogram?A histogram refers to a type of chart that is used to graphically represent and display a set of data points into user-specified ranges, especially through the use of bars (rectangles).
Based on the distribution table, we can deduce the following points:
The frequencies of the bedroom areas are not equal.The frequencies of the first three bedroom areas are greater than the last two (2) areas, which implies that there would be more data on the left side.This ultimately implies that, the distribution of data on the histogram is right-skewed and as such the mean is greater than the median.

Mr. Sanford left half of his fortune to April, his daughter. He left of the remaining half to his uncle Jed. He left half of the remaining half to his favorite charity. He left the remaining $30,000 to the local animal shelter. What was the total amount of Mr. Sanford’s fortune?
9514 1404 393
Answer:
$240,000
Step-by-step explanation:
Let f represent Mr. Sanford's fortune.
1/2x went to April, so 1/2x remains.
1/2(1/2x) = 1/4x went to Jed, so 1/2x -1/4x = 1/4x remains.
1/2(1/4x) = 1/8x went to charity, so 1/4x -1/8x = 1/8x remains.
That remaining 1/8x was $30,000, so the total amount of Mr. Sanford's fortune was ...
8 × $30,000 = $240,000
Gia is running for school president. Her best friend designed a rectangular button that measures 2.5 inches by 2 inches. Gina liked the button so much she produced a campaign poster, which measures 5 feet by 4 feet. What scale factor did Gina use to make the poster from the button?
Answer:
24:1
Step-by-step explanation:
To find the scale used to make the poster we just need to find the ratio between the poster and the button, and we do this by dividing the length and width of the poster by the length and width of the button.
So, we have that:
ratio = length poster / length button = 5 feet / 2.5 inches = 2 feet to 1 inch
ratio = width poster / width button = 4 feet / 2 inches = 2 feet to 1 inch
if 1 foot is equal 12 inches, we have a ratio of 2*12 inches to 1 inch = 24 to 1 (24:1)
What is the probability of tossing 3 heads in a row when flipping a coin?
Answer:
0.125
Step-by-step explanation:
Assuming the coin is fair (most coins are not completely fair) and that the person flipping is not able to control the tosses (some people can) then the chance is 0.125. On each flip, the chance is 1/2. The combination is simply the product of three tosses, since the events are independent.

Miss Quinn made 4 loaves of bread for a dinner party. She cut one loaf in half and put a piece in her freezer. She then divided the remaining full loaves of bread into sixths. Her guests ate 7 pieces. How much bread does Miss Quinn have left?
Answer:
2 5/6
Mrs Quinn has 2 full loaves of bread and 5 pieces of the 1/6 portions of the bread.
Step-by-step explanation:
Mrs Quinn had 4 loaves of bread
1 loaf was divided into two halves
1/2 was kept in the freezer
3 loaves was divided into 1/6 pieces
Step 1
How many 1/6 pieces can we find in 3 loaves?
1 loaf of bread = 6 pieces of 1/6 portions of bread
3 loaves of bread =
3× 6 pieces = 18 pieces of 1/6 portions of bread in total.
From the question, her guests ate 7 pieces
The number of pieces left = 18 - 7
= 11 pieces left.
Step 2
We are asked how many loaves of bread does Mrs Quinn have left?
This is calculated by adding up the 11 pieces of 1/6 portions of the bread with the first loaf of bread that she divided into 2
The total would be
= 1 loaf + 11 pieces of 1/6 sizes of bread
= 1 loaf + 11( 1/6)
= 1 + 11/ 6
= 1 + 1 5/6
= 2 5/6
Therefore Mrs Quinn has 2 full loaves of bread and 5 pieces of the 1/6 portions of the bread.
Final answer:
After dividing and serving bread at her dinner party, Miss Quinn has 11 pieces of bread plus the half loaf she initially put in her freezer left.
Explanation:
Miss Quinn made 4 loaves of bread for a dinner party. She cut one loaf in half and put a piece in her freezer. She then divided the remaining full loaves of bread into sixths. Her guests ate 7 pieces. How much bread does Miss Quinn have left?
First, let's figure out how many pieces of bread Miss Quinn had after cutting and dividing the loaves. She had 4 loaves of bread total. After cutting one loaf in half and storing one half, she was left with 3.5 loaves. She then divided the 3 full loaves into sixths, resulting in 18 pieces (3 loaves × 6 pieces), plus the half loaf she did not cut into sixths. Therefore, before the guests ate, Miss Quinn had 18 pieces + 1 half loaf (considered as 1 unit here), for a total of 19 units of bread.
Her guests ate 7 pieces of the bread divided into sixths, leaving Miss Quinn with 18 - 7 = 11 pieces of the sixths and the half loaf in the freezer. Therefore, Miss Quinn has 11 pieces of bread + 1 half loaf left after her guests have eaten.

Write the equation x2=7x in standard form.
Answer:
i believe it's x2-7x=0
Step-by-step explanation:
To write the equation x^2 = 7x in standard form, subtract 7x from both sides and rearrange the terms in descending order of exponents.
Explanation:The equation x^2 = 7x is a quadratic equation. To write it in standard form, we need to move all the terms to one side and set the equation equal to zero.
Subtracting 7x from both sides, we get x^2 - 7x = 0.
Next, we rearrange the terms in descending order of exponents: x^2 - 7x = 0.
