Given that the volume of a rectangular prism is length x width x height, this problem can be solved by setting up the equation 2w * w * 8 = 400, where w is the width and 2w is the length. Solving this equation, we find that the width is 5 feet and the length is 10 feet.
Explanation:In mathematics, the volume of a rectangular prism is given by the formula length x width x height. We are given that the volume of the storage container is 400 cubic feet, its height is 8 feet, and the length is twice the width. Let us denote the width as w, then the length is 2w.
From the given volume formula, we have:
Length x Width x Height = Volume
Substituting the values, we get:
2w * w * 8 = 400
Solving this equation, we find:
w^2 = 25
Taking the square root of both sides, we get:
w = 5
Substituting w=5 into 2w, we find the length:
Length = 2*5 = 10
So the width of the container is 5 feet and the length is 10 feet.

what is the distance between (4,2) and (8,5)
Answer:
The distance between points P1 = (4,2) and P2=(8,5) is 5.
Step-by-step explanation:
Let P1 = (4,2) and P2=(8,5)
The distance between two points can be found using formula:
[tex]d(P,Q), \sqrt{(x_{2}-x_{1})^2+ (y_{2}-y_{1})^2}[/tex]
where x₁ = 4 , x₂=8, y₁= 2 and y₂ = 5
Putting values in the formula
[tex]=\sqrt{(8-4)^2+(5-2)^2} \\=\sqrt{(4)^2+(3)^2} \\=\sqrt{16+9} \\=\sqrt{25} \\=5[/tex]
So, the distance between points P1 = (4,2) and P2=(8,5) is 5.
Final answer:
The distance between the points (4,2) and (8,5) can be found using the Pythagorean Theorem. After calculating the squares of the differences in the x and y coordinates and adding them, the square root of the sum gives a distance of 5 units.
Explanation:
The distance between two points in a two-dimensional plane can be calculated using the Pythagorean Theorem. The coordinates of the points provided are (4, 2) and (8, 5). To find the distance, we calculate the difference in the x-coordinates and the difference in the y-coordinates, and then square both values before adding them together. This gives us the distance squared.
The formula is as follows:
d² = (x2 - x1)² + (y2 - y1)²
In this scenario:
d² = (8 - 4)² + (5 - 2)²
d² = (4)² + (3)²
d² = 16 + 9
d² = 25
Finally, we take the square root of the distance squared to get the distance:
d = √25
d = 5
The distance between the points (4,2) and (8,5) is 5 units.
A ski resort has 18 inches of snow on the ground. The snow is falling at a rate of 4 inches per hour. which type of functions best model this situation?
Answer:
Linear Function
[tex]y=4x+18[/tex]
Step-by-step explanation:
Let
x----> the time in hours
y----> the total inches of snow on the ground
we know that
The function that best model this situation is the linear function
so
[tex]y=mx+b[/tex]
In this problem
[tex]m=4\frac{in}{h}[/tex]
[tex]b=18\ in[/tex] ----> the y-intercept
substitute
[tex]y=4x+18[/tex]
Answer:
Linear decreasing function best model this situation and the required function is
f(x)=4x+18
Step-by-step explanation:
It is given that a ski resort has 18 inches of snow on the ground. The snow is falling at a rate of 4 inches per hour.
If a function has constant rate of change, then the it is a linear function.
It the given case the rate of change is constant so linear function best model this situation.
The slope intercept form of linear function is
[tex]f(x)=mx+b[/tex] ... (1)
where, m is slope and b is y-intercept or initial value.
Ski resort has 18 inches of snow on the ground it means initial value is 18.
The snow is falling at a rate of 4 inches per hour. So, m=4.
Substitute m=4 and b=18 in equation (1).
[tex]f(x)=4x+18[/tex]
Therefore the required function is f(x)=4x+18.

A polynomial function can be written as (x + 2)(x + 3)(x − 5). What are the x-intercepts of the graph of this function? (1 point) (2, 0), (3, 0), (−5, 0) (−2, 0), (−3, 0), (5, 0) (2, 0), (3, 0), (5, 0) (−2, 0), (−3, 0), (−5, 0)
Answer:
(-2, 0), (-3, 0), and (5, 0)
Step-by-step explanation:
The x-intercept is found when y = 0.
So, we have to find x when (x + 2)(x + 3)(x - 5) = 0
We can do that by pulling apart all parts, because if one part = 0, the whole thing will have to be too (multiplication property of identity).
1. When x + 2 = 0, x = -2
2. When x + 3 = 0, x = -3
3. When x - 5 = 0, x = 5
That gives us (-2, 0), (-3, 0), and (5, 0)
Answer:
(-2, 0), (-3, 0) and (5, 0)Step-by-step explanation:
x-intercepts are for
(x + 2)(x + 3)(x - 5) = 0
The product is equal to 0 if one of the factors is equal to 0.
Therefore
x + 2 = 0 or x + 3 = 0 or x - 5 = 9
x + 2 = 0 subtract 2 from both sides
x = -2
x + 3 = 0 subtract 3 from both sides
x = -3
x - 5 = 0 add 5 to both sides
x = 5

Answer:
Step-by-step explanation:
The first question is true. In order for a relation to be a function, it has to have only one x value for every y value. y = 3x - 5 is a straight line, so it doesn't share any x values with any y values. In other words, each x value in that graph will not be "used" more than once. Also, the function will pass the vertical line test. this means that if you draw a perfectly vertical line through the function ANYWHERE it will only go through the function at a single point.
The second question is false. There are several different types of functions that come to mind right away, besides a straight line. There's a parabola, which opens up like a "u" (at least the positive one does!), an absolute value function, a cubic function, an exponential function, a log function...

I do not understand any of the questions its asking :c
Answer:
Step-by-step explanation:
The total number of students is 350 + 50 + 225 + 375 = 1000.
There are 225 students in band only, as well as 50 students in both band and choir. So there are 275 students in band out of the total of 1000, or 27.5%.
There are 350 students in choir only, as well as 50 students in both choir and band. So there are 400 students in choir, 50 of whom are also in band. So the probability is 50/400, or 12.5%.
The probabilities are not the same.
Since the probabilities are not the same, the probability of being in band is affected by whether or not the student is in choir. So the events are not independent.

What percent of 72 is 27?
if we take 72 as the 100%, what is 27 off of it in percentage?
[tex]\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 72&100\\ 27&x \end{array}\implies \cfrac{72}{27}=\cfrac{100}{x}\implies \cfrac{8}{3}=\cfrac{100}{x}\implies 8x=300 \\\\\\ x=\cfrac{300}{8}\implies x=\cfrac{75}{2}\implies x=37.5[/tex]
To calculate the percentage, divide the part (27) by the whole (72) and multiply by 100, resulting in 37.5%.
Percentage is a way of expressing a portion or fraction of a whole as a value out of 100. It is commonly used to compare relative quantities, represents proportions, or express the relationship between a part and a whole.
The term "percent" comes from the Latin phrase "per centum," which means "per hundred." It signifies that percentages are calculated on a scale of 100.
In practical terms, a percentage represents a fraction of a whole, where the whole is equal to 100%. It allows us to easily compare different quantities and understand their relative sizes or proportions.
To calculate a percentage, you typically divide the part (the specific quantity you want to express as a percentage) by the whole (the total or reference quantity) and then multiply by 100 to obtain the value as a percentage.
To calculate the percentage, you can divide the given number (27) by the total number (72) and then multiply the result by 100. So, to find out what percent 27 is of 72:
(27 ÷ 72) × 100 ≈ 37.5%
Therefore, 27 is approximately 37.5% of 72.

The tape diagram represents an equation. Write an equation to solve
The equation represented by the tape diagram is: 2x + 3 = 5x
This can be solved by subtracting 2x from both sides: 3 = 3x
Dividing both sides by 3 gives the solution: x = 1
Therefore, the equation to solve is: 2x + 3 = 5x
The tape diagram represents the following equation:
2x + 3 = 5x
This can be solved by subtracting 2x from both sides:
2x + 3 - 2x = 5x - 2x
3 = 3x
Dividing both sides by 3 gives the solution:
x = 3 / 3
x = 1
Therefore, the equation to solve is:
2x + 3 = 5x
The solution is:
x = 1
The equation to solve m is 2/3 = 1/4 + m.
The equation you wrote, 2/3 = 1/4 + m, is indeed correct based on the tape diagram you described.

Find the quotient 7 / 1/5
The quotient of 7 and 1/5 is calculated by multiplying 7 by the reciprocal of 1/5, which is 5. This yields the result 35.
Explanation:To compute the division of integers and fractions, we generally 'multiply by the reciprocal'. The reciprocal of a fraction is obtained by reversing the numerator and denominator.
In this case, you are asked to obtain the quotient of 7 and 1/5. The reciprocal of 1/5 is 5/1, or simply 5. Thus, we manipulate the problem from division to multiplication:

why is Pi never ending?
If the decimal expansion of pi would end, then it would have to be a rational number, ie pi could be written as a fraction pi = p/q with integers p and q. There are many proofs that this is not the case, but they are all a bit complicated
Pi is an irrational and transcendental number, meaning it never terminates or repeats. Its non-ending and non-repeating nature is reflected in its definition as the ratio of a circle's circumference to its diameter. Pi's transcendence ensures it cannot be expressed by any algebraic equation with rational coefficients.
Understanding the Nature of Pi ( 3.141592653589793237...)
Pi ( 3.14159...) is known to be a non-terminating, non-repeating decimal, which classifies it as an irrational number. This means that no matter how many digits you calculate, Pi will never repeat in a pattern nor end. The number has been calculated to trillions of digits without any repeating pattern emerging.
The non-ending nature of Pi arises from its definition as the ratio of a circle's circumference to its diameter. This ratio is the same for all circles, but it can never be expressed exactly by a fraction or a finite decimal.
Moreover, Ferdinand von Lindemann's proof that Pi is a transcendental number further solidifies that it cannot be the solution of any algebraic equation with rational coefficients, making Pi an essentially complex and infinite entity in mathematics.

A painter leans a 12 ft ladder against a building. The base of the ladder is 5 ft from the building. To the nearest foot, how high on the building does the ladder reach?
For this problem you must do Pythagorean theorem:
[tex]a^{2} + b^{2} =c^{2}[/tex]
In this example 10ft is c and 7ft is a (or it could be b, and you'll be solving for a instead of b. It's the same thing, since a and b are both legs)
Plug what you know into the equation:
[tex]7^{2} +b^{2} = 10^{2}[/tex]
49 +b^{2} = 100
Bring 49 to the right side by subtracting it:
b^{2} = 51

I can write it in its "vertex form"
[tex]y=a(x-d)^{2} +e[/tex] being (d,e) the coordinates of the vertex of said parabola.
by clearing the equation I can see that [tex]d=\frac{-b}{2a}[/tex] so I substitute[tex]d=-\frac{4}{2*1} =-2[/tex]
Now taking d as the value for the x axis of the vertex coordinate, I substitute d in x, in the initial equation
