What is the ratio of the volume of the cone to the volume of the square pyramid?
Answer:
The ratio of the volume of cone to square pyramid is π or 3.14
Step-by-step explanation:
Given
Shapes: Cone and Square Pyramid
Diameter of the cone, d = 10 inches
Height of the cone, h = 12 inches
Height of the pyramid, h = 12 inches
Base edge of the pyramid, a = 5 inches
Required:
Ratio of the volume of cone to square pyramid.
First, we calculate the volume of each shapes
Volume of a cone is calculated as follows;
Volume = ⅓πr²h
Where r = radius = ½d
Recall that d = 10 inches
So, r = ½ * 10 inches
r = 5 inches.
Hence,
Volume = ⅓ * π * 5² * 12
Volume = ⅓ * π * 25 * 12
Volunteer = π * 25 * 4
Volume = 100π in³
Calculating Volume of the pyramid.
Volume = ⅓a²h
Recall that a = 5 and h = 12
So, Volume = ⅓ * 5² * 12
Volume = ⅓ * 25 * 12
Volume = 25 * 4
Volume = 100 in³
Now that both volumes have been calculated.
The ratio of the volume of cone to square pyramid is calculated by dividing the volume of the cone by the volume of the square pyramid.
Ratio = 100π ÷ 100
Ratio = π
Taking π as 3.14
Ratio = 3.14
Hence, the ratio of the volume of cone to square pyramid is π or 3.14

Find the volume of the cone.round to the nearest tenth. Height: 10 radius:2
Answer:
41.9 units³
Step-by-step explanation:
(please see attached for reference)
The volume of a cone is given by:
V = (1/3) πr²h where,
V = volume (we are asked to find this)
π = 3.142
r = radius = given as 2
h = height = given as 10
Substituting the known values into the above equation,
V = (1/3) πr²h
= (1/3) (3.142) (2²)(10)
= 41.893
= 41.9 units³ (nearest tenth)

2x -y = 13
Step-by-step explanation:
y+3= 2(x-5)
Distribute
y+3 = 2x-10
Subtract 2x from each side
-2x +y+3 = 2x-2x-10
-2x +y +3 = -10
Subtract 3 from each side
-2x+y+3-3 = -10-3
-2x+y = -13
Multiply each side by -1 since A should be positive

5 friends go out to lunch and order 3 large pizzas. The friends divided the pizzas evenly. Find how much pizza each friend got as a decimal
Answer:4.8 slices
Step-by-step explanation:there are 8 slices in a pizza times 3 pizzas divided by 5 friends
Each of the 5 friends gets 0.6 of a pizza when they evenly divide 3 large pizzas.
When 5 friends go out to lunch and order 3 large pizzas, dividing the pizzas evenly, we can calculate the amount of pizza each friend got. To start, we need to determine the total amount of pizza available in terms of 'pizza units'. Since there are 3 pizzas and 5 friends, we divide the pizzas into 5 equal parts. This means that each of the 3 pizzas is divided into 5 slices (assuming each pizza can be divided into equal parts).
We can represent this as a fraction where the numerator is the total number of pizzas (3) and the denominator is the number of friends (5). So, each friend gets
3/5 of a pizza. Now, converting that fraction into a decimal, we divide the numerator by the denominator. Thus, 3 divided by 5 equals 0.6. Therefore, each friend gets 0.6 of a pizza as a decimal.

Answer:
x=4
Step-by-step explanation:Trust me
4x-7=9
4x-7+7=9+7
4x=16
4x/4 = 16/4
X=4
Answer: x = 4
Step-by-step explanation: To solve for x, we must first isolate the term containing x which in this problem is 4x.
To isolate 4x, we have to get rid of the -7 by adding
7 to both sides of the equation.
That leaves us with 4x = 16.
Now divide both sides by 4 to find that x = 4.
Ettiene solved a quadratic equation. His work is shown below.
In which step did Ettiene make an error?
The Step 2 shows the mistake done by Ettiene.
What is Quadratic Equation?A quadratic equation is a second-order polynomial equation in a single variable x, ax²+bx+c=0. with a ≠ 0 .
It has at least one solution because it is a second-order polynomial equation, which is guaranteed by the algebraic fundamental theorem.
Given:
The given equation is x(x+4)=117.
Step1: x²+4x=117
Now, b/2 =4/2 =2
Then, add 2² to both the sides of an equation, we get
x²+4x+2²=117+2²
x²+4x+4=117+4
(x+2)²=121
x+2=±√121
x+2=±11
x=±11-2

what is the x value of the vertex called
Answer:
The vertex form of a quadratic is given by
y = a(x – h)^2 + k, where (h, k) is the vertex. h may act as "x" in this case.
Step-by-step explanation:
The vertex form of a quadratic is given by
y = a(x – h)^2 + k, where (h, k) is the vertex.
You must simply get an equation in this format to find h and k.
The x value of the vertex in a parabola is found using the formula -b/(2a), which represents the x-coordinate of the vertex, a critical point that determines the parabola's maximum or minimum value.
The x value of the vertex in a parabola is a critical point that determines the maximum or minimum of the quadratic function. In a quadratic equation of the form f(x) = ax^2 + bx + c, the x-coordinate of the vertex can be found using the formula -b/(2a). This formula is derived from completing the square or using calculus to find the critical points of the function. Once you determine the x-coordinate of the vertex, you can substitute it back into the original equation to find the corresponding y-coordinate, giving you the full coordinates of the vertex of the parabola.

Which of the following scatter plots shows a strong, negative linear association between variables ?
The scatter plot that shows a strong, negative linear association between variables is Scatter Plot A.
Option A is the correct answer.
What is a scatterplot?A scatterplot is a type of graphical display that is used to represent the relationship between two continuous variables.
In a scatterplot, each point represents the values of the two variables, with one variable being plotted along the x-axis and the other variable being plotted along the y-axis.
The position of each point on the graph represents the values of both variables for that particular observation.
We have,
A strong, negative linear association between variables means that as one variable increases, the other variable decreases consistently and predictably.
This relationship is described as negative because the two variables move in opposite directions.
For example, if you were studying the relationship between temperature and the demand for ice cream, you would expect a strong, negative linear association because as the temperature increases, the demand for ice cream decreases.
In terms of a scatterplot, this relationship would be seen as a cluster of points that form a straight line sloping downwards from left to right.
Thus,
The scatter plot that shows a strong, negative linear association between variables is Scatter Plot A.

Enter the missing numbers in the boxes to complete the table of equivalent ratios.
Time (month) Weight (lb)
2 __
__ 20
6 __
10 50
To complete the table of equivalent ratios, we established a simplified ratio of 1 month to 5 lb from the given information, then we used this to calculate the missing values: in 2 months the weight is 10 lb, corresponding to 20 lb there are 4 months, and in 6 months the weight is 30 lb.
To find the missing numbers in the table of equivalent ratios, we need to look for a pattern or use cross-multiplication. We can see from the given information that in 10 months the weight is 50 lb. Using this information, we can set up a ratio comparing time to weight. Let's fill out the table with the equivalent ratios.
Step-by-step Calculation
Take the given ratio of 10 months to 50 lb. This can be simplified to 1 month to 5 lb.
Now that we have the basic ratio, we can find the missing values. For 2 months, we multiply 2 by 5 lb, giving us 10 lb for the first missing number.
To find the time that corresponds to 20 lb, we take 20 lb and divide it by 5 lb/month, giving us 4 months for the second missing number.
For 6 months, we multiply 6 by 5 lb, which gives us 30 lb for the third missing number.
Now we can fill in the table:
Time (month): 2, Weight (lb): 10
Time (month): 4, Weight (lb): 20
Time (month): 6, Weight (lb): 30
Time (month): 10, Weight (lb): 50

$8,008 for tuition and fees each year.
Room and housing are an additional $8,392 per year.
Total = 8008 + 8392 = $16400
1.) Scholarship - $1,000
Grant - $1,000
Student Loan - $4,500
Months - 42
Yearly = 42/12 = 3.5 years
Total support = 1000 + 1000 + 4500
= $6500
Savings = 16400 - 6500 = 9900
First year savings = 9900/3.5
= 2828.57 dollars
2. Scholarship - $6,000
Grant - $500
Student Loan - $4,500
Months - 24
Yearly = 24/12 = 2
Support = 4500 + 6000 + 500
= $11000
Savings = 16400 - 11000
= 5400 dollars
First year savings = 5400/2
= 2700 dollars
3.) Scholarship - $10,000
Grant - $2,000
Student Loan - $0
Months - 18
Yearly = 18/12 = 1.5
Support = 10000 + 2000 = $12000
Savings = 16400 - 12000
= 14400 dollars
First year savings = 4400/1.5
= 2933.33 dollars
4.) Scholarship - $3,000

As 100/474 = -2 1/10 or -50/237
We balance the 8. then we balance the 50ml so that 100/424 = -25/106 = -2 4/10 so we see that 50ml minimum in the problem is required and this creates a 1/8 increase with each pump.
