Answer:
The exact volume of a cone is 10 yd³.
Step-by-step explanation:
Given:
Height of cone (h) is 6 yd and base (b) is 5 yd.
Now, to get the volume we need to find the radius.
So, to find radius we put the formula of base:
Let the radius be [tex]r[/tex]
Base=[tex]\pi r^2[/tex]
[tex]b=\pi\times r^{2}[/tex]
[tex]5=\pi\times r^{2}[/tex]
Dividing both sides by π and using square root on both the sides:
[tex]5\div \pi=(\pi \times r^{2}) \div \pi[/tex]
[tex]\frac{5}{\pi}=r^{2}[/tex]
[tex]\frac{5}{\pi}=r^{2}[/tex]
[tex]r^{2}=\frac{5}{\pi}-----1[/tex]
Now, putting the formula for getting the volume (v) of cone:
Volume = [tex]\pi r^2\frac{h}{3}[/tex]
[tex]v=\pi\times r^{2}\times \frac{6}{3}[/tex]
[tex]v=\pi\times r^{2}\times 2[/tex]
Substituting the value of [tex]r^2[/tex] from equation (1), we get:
[tex]v=\pi\times \frac{5}{\pi}\times 2[/tex]
[tex]v=10[/tex] yd³
Volume of cone is 10 yd³
Therefore, the exact volume of a cone is 10 yd³.
A baker’s dozen (13) of cookies is on sale for $2.08.
Complete Question
A baker's dozen (13) of cookies is on sale for $2.08. What is the cost of an individual cookie?
Answer:
The cost of an individual cookie is $0.16
Step-by-step explanation:
Given
Specifically, it was stated that the baker's dozen is 13 pieces
Hence. A dozen cookies = 13 cookies
Price of a dozen cookies = $2.08
In other words, the price of 13 cookies is $2.08
To get the cost of an individual cookie, we have to divide the price of a dozen cookies by the number of cookies. This is calculated as follows:
[tex]Cost of Cookies = \frac{Price of Cookies}{Number of Cookies}[/tex]
By Substituting the right values,
[tex]Cost of Cookies = \frac{Price of Cookies}{Number of Cookies}[/tex]
becomes
[tex]Cost of Cookies = \frac{2.08}{13}[/tex]
[tex]Cost of Cookies = 0.16[/tex]
Hence, the cost of an individual cookie is $0.16

Answer:
the first one should be 2 because
if you put 2 it would look like this:
7x + 2 = 7x + 2
and if you answer it or try to simplify
7x + 2 = 7x + 2 or 7x + 2 = 7x + 2
- 2 - 2 -7x -7x
7x = 7x 2 = 2
/7 /7
x = x
and for the second one could be any number but 2
to prove this lets choose 5
and now to solve:
7x + 2 = 7x + 5 or 7x + 2 = 7x + 5
-7x -7x - 2 - 2
2 ≠ 5 7x = 7x + 3
-7x -7x

The table shows the gallons of water in a pool over time.
A two column table with six rows. The first column, Time in minutes, has the entries, 0, 1, 2, 3, 4, 5. The second column, Water in Pool in gallons, has the entries, 50, 44, 38, 32, 26, 20.
Choose the term that describes the slope of the line of a graph representing the data in the table.
The slope of a line graphed to represent the volume of water in a pool over time would be described as .
Answer:
negative
Step-by-step explanation:
The slope of a line graphed to represent the volume of water in a pool over time will be 6 and the equation of the line representing the table
y = - 6x + 50
What is the general equation of a Straight line?
The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written as -
Ax + By + C = 0
By = - Ax - C
y = (- A/B)x - (C/A)
We have a table as given in the question as follows -
Time (in minutes) Water (in gallons)
0 50
1 44
2 38
3 32
4 26
5 20
We can write the slope of the line as follows -
The slope of the line will be -
m = (y₂ - y₁)/(x₂ - x₁)
m = (44 - 50)/(1 - 0)
m = -6
At [x] = 0, the [y] coordinate is 50. Therefore, the equation of the line representing the table -
y = - 6x + 50
Refer to the graph attached.
Therefore, the slope of a line graphed to represent the volume of water in a pool over time will be 6 and the equation of the line representing the table y = - 6x + 50

If D=25 use information in the figure below to determine angle F
Answer:
130°
Step-by-step explanation:
DEF is an isosceles triangle with base DE and DF = EF.
By definition, base angles of an isosceles triangle are equal.
Hence ∠FDE = ∠DEF = 25°
Angle F = 180° - ∠FDE - ∠DEF
= 180° - 25° - 25°

If Miranda flips a coin twice, what is the probability that both coins will land heads up? The probability that the first coin will land heads up is 1/8, 1/4, 1/2, 3/4? . The probability that the second coin will land heads up is 1/8, 1/4, 1/2, 3/4. The probability that both coins will land heads up is 1/8, 1/4, 1/2, 3/4?
Answer:
I just did it and got it right so hoped it helped you ;)
1/2
1/2
1/4
Step-by-step explanation:
The probability that both coins will land heads up when Miranda flips them twice, assuming each coin is fair and has an equal chance of landing heads or tails, is 1/4. Each flip has a probability of 1/2 for heads, and these probabilities multiply for sequential independent events.
Explanation:If Miranda flips a coin twice, the probability that both coins will land heads up needs to be calculated by multiplying the probability of the first coin landing heads up by the probability of the second coin doing the same. Since the chance of a coin landing on heads (assuming it is a fair coin) is usually 50%, that is 1/2 for each flip. Therefore, to find the probability of both coins landing heads up, we multiply these probabilities together: 1/2 × 1/2 = 1/4.
In a broader context, the more times you flip a coin, the closer you are likely to get to 50% heads due to the law of large numbers. Notably, in experiments such as one conducted by Karl Pearson, after 24,000 coin flips, the relative frequency of heads was 12,012/24,000 ≈ 0.5005, closely aligning with the theoretical probability of 1/2. An essential assumption in determining these probabilities is that the coin is fair and each flip is independent of the others.

) Ava walks from her apartment to the train station, which is 25 blocks away. She has walked
15 blocks so far. Ava wants to know what percent of the distance to the train station she
has walked so far.
To find out what percent of the distance Ava has walked so far, we can set up a proportion and solve for x. Ava has walked 60% of the distance to the train station.
Explanation:To find out what percent of the distance Ava has walked so far, we can set up the following proportion:
15/25 = x/100
Where 15 is the distance Ava has walked, 25 is the total distance to the train station, x is the unknown percentage, and 100 represents 100%. To solve for x, we can cross multiply and divide:
15 * 100 = 25 * x
1500 = 25 * x
Dividing both sides by 25, we get:
x = 1500/25
x = 60
Therefore, Ava has walked 60% of the distance to the train station.
Final answer:
To find the percent of the distance Ava has walked so far to the train station, divide the distance she has walked by the total distance and multiply by 100. In this case, Ava has walked 15 blocks out of 25 blocks, so she has walked 60% of the distance.
Explanation:
To find the percent of the distance Ava has walked so far, you can divide the distance she has walked by the total distance to the train station and then multiply by 100.
In this case, Ava has walked 15 blocks out of 25 blocks to the train station. So, the percent of the distance she has walked so far can be calculated as:
Percentage = (15/25) * 100 = 60%
The lengths of the sides of a quadrilateral are in extended ratio 1:1:2:3. the perimeter is 56 feet what are the lengths of the sides
Length of sides of quadrilateral are 8 feet, 8 feet, 16 feet, 24 feet
Solution:Given that length of the sides of a quadrilateral are in extended ratio 1:1:2:3
Perimeter of the quadrilateral = 56 feet
Need to determine length of the sides
As length of the sides of a quadrilateral are in extended ration 1: 1: 2: 3
lets assume that four sides of rectangle = 1x, 1x, 2x and 3x
Perimeter of quadrilateral = sum of length of four sides
=> Perimeter of quadrilateral = 1x + 1x + 2x + 3x = 7x
As given that perimeter = 56 feet
=> 56 = 7x
x = 8
Then the length of sides are:
1x = 1(8) = 8 feet
1x = 1(8) = 8 feet
2x = 2(8) = 16 feet
3x = 3(8) = 24 feet
A computer and printer cost a total of $1028. The cost of the computer is three times the cost of the printer. Find the cost of each item.

Leona purchased a $1,000 bond having a quoted price of 99.875. She had to pay a 5.5% brokerage fee (of the selling price). What was the total cost of the bond (to the nearest whole cent)?
$943.82
$1,064.44
$534.77
$2,054.22
None of these choices are correct.
Answer:
None of these choices are correct.
Step-by-step explanation:
The quoted value of 99.875, means that this bond is sold at 99.875% of the face value and not at a price of $99.875.
Therefore, calculate price;
Price = 0.99875 * 1000
Price = $998.75
Since brokerage fees is 5.5% of the selling price, Leona will pay additional cost to the quoted price making the total cost to be more than $998.75;
Brokerage fees = (0.055*998.75) = $54.93
Total cost = $998.75 +$54.93
= $1053.68
Therefore, none of the choices is correct.

Increase 1/2kg by 250g
One kilogram is made of 1000 grams. So, 1/2kg is made of 500 grams. If we add 250 grams, we have 750 grams, or 0.75kg.
To increase 1/2 kg by 250g, add the two values is 750g.
In mathematics, we often encounter situations where we need to perform operations with different units of measurement. In this case, you want to increase 1/2 kg by 250g. The first step is to convert both quantities to a common unit to facilitate the addition.
Step 1: Convert 1/2 kg to grams
We know that 1 kg is equal to 1000 grams (1 kg = 1000g). To find out how many grams are in 1/2 kg, we multiply 1/2 by 1000:
1/2 kg * 1000g/kg = 500g.
So, 1/2 kg is equivalent to 500g.
Step 2: Perform the addition
Now, we have both quantities in the same unit (grams). The addition becomes straightforward:
500g + 250g = 750g.
Thus, when you increase 1/2 kg by 250g, the result is 750 grams.
In summary, to add quantities with different units, it's crucial to convert them into the same unit before performing the operation. Here, we converted kilograms to grams and then added the values to get the final result of 750g.

Mrs.Young’s recipe for haggis calls for 2 1/4 cups of stock and serves 12. How much stock will she need to make 4 servings of haggis?
Answer:
byzantine style of architecture is an example of haggis sophias style
Step-by-step explanation:
Final answer:
To find out how much stock is needed for 4 servings of Mrs. Young's haggis recipe, we use proportional relationship calculations to arrive at 3/4 cup of stock.
Explanation:
The student needs to determine how much stock Mrs. Young will need for 4 servings of her haggis recipe if the original recipe, which serves 12, calls for 2 1/4 cups of stock. To solve this, a proportional relationship can be used, as follows:
Multiply the number of servings in the original recipe by the amount of stock to find the stock per serving.
Divide the original number of servings (12) from the result to find the stock needed for one serving.
Multiply the amount of stock for one serving by the new number of servings (4) to determine the total stock needed.
The calculation would be: (2 1/4 cups ÷ 12 servings) × 4 servings. Since 2 1/4 cups is equal to 9/4 cups, the arithmetic gives us: (9/4 cups ÷ 12) × 4 = 3/4 cup of stock needed for 4 servings.

need some help with this question : When driving to their family reunion, River's mom drove 10 miles at a rate of x mph and then 25 miles at a rate of x + 10 mph . The total driving time was 45 minutes. What were the two driving speeds at which River's mom drove?
Answer:
The speed of River's mom drove for 10 miles distance is 0.234 mph
The speed of River's mom drove for 25 miles is 10.234 mph
Step-by-step explanation:
Given as :
The first distance cover by River's mom = 10 miles
The rate of speed = x mph
The second distance cover by river's mom = 25 miles
The rate of speed = x + 10 mph
The total driving time = 45 min
Now, According to question
Time = [tex]\dfrac{\textrm Distance}{\textrm speed}[/tex]
So, 45 = [tex]\dfrac{10}{x}[/tex] + [tex]\dfrac{25}{x + 10}[/tex]
Or, 9 = [tex]\dfrac{2}{x}[/tex] + [tex]\dfrac{5}{x + 10}[/tex]
Or, 9 × x × ( x + 10 ) = 2 × ( x + 10 ) + 5 x
Or, 9 x² + 90 x = 2 x + 20 + 5 x
Or, 9 x² + 90 x = 7 x + 20
Or, 9 x² + 90 x - 7 x - 20 = 0
Or, 9 x² + 83 x - 20 = 0
Solving this quadratic equation
x = [tex]\frac{-b\pm \sqrt{b^{2}-4\times a\times c}}{2\times a}[/tex]
Or, x = [tex]\frac{-83\pm \sqrt{83^{2}-4\times 9\times (-20)}}{2\times 9}[/tex]
Or, x = [tex]\frac{-83\pm \sqrt{7609}}{18}[/tex]
∴ x = [tex]\frac{-83+87.22}{18}[/tex] , tex]\frac{-83-87.22}{18}[/tex]
I.e x = 0.234 , - 9.4567
We consider x = 0.234
So, The speed for 10 miles distance = x = 0.234 mph
and The speed of 25 miles = x + 10 = 0.234 + 10 = 10.234 mph
Hence The speed of River's mom drove for 10 miles distance is 0.234 mph
and The speed of River's mom drove for 25 miles is 10.234 mph Answer
Final answer:
To find the two driving speeds, use the distance formula and set up two equations. Simplify the equations to find the speeds.
Explanation:
To find the two driving speeds at which River's mom drove, we can use the formula distance = speed x time. We know that the total driving time was 45 minutes. We can set up two equations using the given information:
10 = x ⋅ (45/60)
25 = (x + 10) ⋅ (45/60)
Simplifying the equations, we get:
x = 20 mph
x + 10 = 30 mph
Therefore, River's mom drove at speeds of 20 mph and 30 mph.
