What is the volume of a right circular cylinder with a diameter at 46.25 cm and a height of 18.5 m?
Answer:
Volume of right circular cylinder(V) is given by:
[tex]V = \pi r^2h[/tex] ......[1]
where,
r is the radius of the cylinder
h is the height of the cylinder.
As per the statement:
A right circular cylinder with a diameter at 46.25 cm and a height of 18.5 m
⇒diameter(d) = 46.25 cm and height(h) = 18.5 cm
We know that:
diameter(d) = 2r
then;
[tex]46.25 = 2r[/tex]
Divide both sides by 2 we have;
[tex]23.125 = r[/tex]
or
r = 23.125 cm
Substitute these given values in [1] we have;
Use [tex]\pi = 3.14[/tex]
[tex]V = 3.14 \cdot (23.125)^2 \cdot 18.5[/tex]
⇒[tex]V = 31,064.5351 cm^3[/tex]
Therefore, the volume of a right circular cylinder to the nearest hundredth is, 31,064.54 cubic centimeters.

The top of the Washington Monument is a triangular pyramid with a triangle base. Each triangular face is 58 feet tall and 34 feet wide and covered with white marble. About how many square feet of marble cover the faces of the pyramid?
Answer:
[tex]3,944ft^{2}[/tex] of marble is needed.
Step-by-step explanation:
The picture below represents the top of the Washington Monument, with 4 triangles, one on the base and the other 3 forming the monument.
First of all whe have to find the area of one pyramid:
[tex]A=\frac{height*width}{2}[/tex]
Replacing the values, we have:
[tex]A=\frac{58ft*34ft}{2}[/tex]
[tex]A=986ft^{2}[/tex]
As we have 4 triangles forming the top of the Monument, we have to multiply by 4 to find the quantity of marble to use:
Quantity of marble=Area of each triangle * quantity of triangles
Quantity of marble=[tex]986ft^{2}*4[/tex]
Quantity of marble=[tex]3,944ft^{2}[/tex]
To find the area of marble covering the Washington Monument's pyramid faces, calculate the area of one triangular face (985 square feet) and then multiply by 3, resulting in approximately 2955 square feet.
The Washington Monument's pyramid at the top has triangular faces that are covered with white marble. Each face is 58 feet tall and 34 feet wide. To find the total area covered by marble, we need to calculate the area of one triangular face and then multiply by the number of faces.
Calculate the area of one triangular face using the formula for the area of a triangle: Area = 1/2 * base * height.Substitute the given measurements: Area = 1/2 * 34 feet * 58 feet = 985 square feet.Each triangular pyramid has three faces. So, multiply the area of one face by 3: Total Area = 3 * 985 square feet = 2955 square feet.Therefore, approximately 2955 square feet of marble cover the faces of the pyramid.

Graph the line with slope -2/3 passing through the point (2,1)
To graph a line with a given slope passing through a point, use the point-slope form of a linear equation. Convert the equation to slope-intercept form, [tex]y = mx+b[/tex]. Plot the line on a graph using the y-intercept and the slope to find additional points.
Explanation:To graph a line with a given slope and passing through a point, we can use the point-slope form of a linear equation, y - y1 = m(x - x1). In this case, the point-slope form would be y - 1 = (-2/3)(x - 2). We can simplify this equation into slope-intercept form, y = mx + b, by distributing the slope and rearranging the terms. After simplifying, the equation becomes y = (-2/3)x + 7/3. Finally, we can plot the line on a graph using the slope-intercept form equation by identifying the y-intercept at (0, 7/3) and using the slope to find additional points on the line.

The length of a rectangle is 4 times its width. The area of the rectangle is 144 square inches. Find the dimensions of the rectangle
The width is 6 inches and the length is 24 inches.
To find the dimensions of the rectangle when given the area and the relationship between length and width, we will use algebra. Let the width be w inches. The length is 4 times the width, so the length is 4w inches. The area of the rectangle is w times the length (4w), which gives us w * 4w = 144 square inches. Simplifying, this equation becomes 4w^2 = 144 inches2. To find w, we divide both sides by 4, getting w^2 = 36. Taking the square root of 36 gives us w = 6 inches. Since the length is four times the width, the length is 24 inches. Therefore, the dimensions of the rectangle are 6 inches by 24 inches.

we are given
Gavin builds furniture for a living. he Sells chairs for $45 and tables for $70 each
So, we can find objective function as
[tex] Z=45x+70y [/tex]
now, we can find inequalities
A table requires 10 hours and $15 worth of supplies to make
so, total hours to make table =10y
amount spent on table =15y
It takes Gavin 4 hours and $10 worth of supplies to build each chair
so, total hours to make chair =4x
amount spent on chair =10x
total number of hours to make chair and table =4x+10y
Gavin wants to work for no more than 40 hours per week
so, we get
[tex] 4x+10y\leq 40 [/tex]
spend no more than $80 on materials
so, we get
[tex] 10x+15y\leq 80 [/tex]
so,

6. How could you change the simulation to generate data for three pets? Result Frequency Heads, Heads 9 Heads, Tails 14 Tails, Heads 18 Tails, Tails 9 Total 50
PLEASE HELP WILL GIVE BRAINLYEST
Answer: what i did was put "change one of the tails, heads or heads, tails to add the data for the 3 pets" because you couldn't tell if it was heads tails or tails heads
Final answer:
To generate data for three pets in a simulation, expand the outcome possibilities to include all combinations of Heads and Tails for three entities, and then record the frequency of each outcome to analyze probabilities or patterns.
Explanation:
To determine how to change a simulation to generate data for three pets when you currently have data for two, you need to expand the number of possible outcomes to account for the additional pet. For the current two-pet scenario, there are four outcomes: Heads-Heads, Heads-Tails, Tails-Heads, and Tails-Tails. When adding a third pet, each of these outcomes would branch into two further outcomes, representing the two possibilities for the third pet (let's call it Pet C).
The possible outcomes would be:
Heads-Heads-HeadsHeads-Heads-TailsHeads-Tails-HeadsHeads-Tails-TailsTails-Heads-HeadsTails-Heads-TailsTails-Tails-HeadsTails-Tails-TailsFor each outcome, you would simulate or record the frequency as you did with the two-pet scenario, totaling the number of trials to ensure you have complete data for analysis. You would then use this data to analyze the probabilities or patterns of outcomes involving three pets.

Which situations accurately describe a ratio of ? Select all that apply
A ratio compares two quantities and can form a proportion when two ratios are equivalent. A unit rate is a ratio with one quantity of one, while a unit scale compares actual object dimensions to a model or drawing. These concepts are used in various fields, including health sciences and when working with scale models or maps.
Explanation:A ratio is a comparison between two different quantities. When we express ratios, we can use a fraction format, a colon, or the word 'to'. Examples include 2/3, 2:3, and '2 to 3'. In certain situations, this comparison can lead to the formation of a proportion, which occurs when two ratios are equivalent, like 1/2 = 3/6. Proportions are especially useful when we deal with scale distances or dimensions, such as in map reading or model building.
A unit rate is a type of ratio in which one of the quantities is one. An example would be 55 miles per hour or 55 miles/1 hour. This is often used when discussing speed or cost per unit.
Similar to a unit rate is a unit scale, which compares the actual dimensions of an object to the dimensions of a model or drawing of the object. An example of a unit scale is 1 inch = 100 feet, which can be written as a ratio of 1 inch/100 ft.
In sectors like the health sciences, ratios are used to describe solutions and are given in terms of proportions, for example, 1:1000. In making comparisons or constructing models, we might set ratios equal to the unit scale to form proportions for various dimensions like length and width.
Four different situations accurately describe ratios.
Certainly! Let's evaluate each situation to see if it accurately describes a ratio.
Sally found five green fruit loops in her cereal bowl, out of every thirteen pieces.
This situation does describe a ratio: 5 green fruit loops to 13 total pieces. The ratio is 5:13.

Help! How do i find a solution set? (I have a texas ti graphing calculator if that helps) An example is
(x - a)(x + b) = 0
How would I find the solution set for this?
Please explain to me in an easy to understand, step by step way.
If you know how to use a texas TI calculator, you can also explain to me how to do it on the calculator, but that is not required
Answer:
The solution set is given by {a, -b}.
Step-by-step explanation:
We have the equation,
[tex](x - a)(x + b) = 0[/tex]
Equating the factors to 0 gives,
[tex](x - a)=0[/tex] and [tex](x + b)=0[/tex]
i.e. x = a and x = -b
So, the solutions of the equation [tex](x - a)(x + b) = 0[/tex] are x= a and x= -b.
Thus, the solution set is given by {a, -b}.
