Answer:
1,500 beds
Step-by-step explanation:
Occupancy rate shelter A = 300 x 20/100 = 60
Let capacity of shelter B be X
60% occupancy ==> 60/100 x X = 0.6X
Occupancy rate of A to rate of B is 1: 15 can be expressed as fraction 1/15
Therefore
60/0.6X = 1/15
1 x 0.6X = 60 x 15
0.6X = 900
X = 900/0.6 = 1,500 beds
c)If 2000 items sell when the price is 30 dollars and if the number of items that are sold decreases by 400 for every 1 dollar increase in price, find the rate of change of the profit when the item price is 30 dollars.
The rate of change of the profit when the item price is $30 is $3600 per dollar increase in price.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Let's call the number of items sold at a price of $p as x(p).
Based on the information given, we can write an equation for x(p) as:
x(p) = 2000 - 400(p - 30)
The profit from selling the items at a price of $p is given by the product of the number of items sold and the price:
Profit(p) = x(p)×p
Taking the derivative of the profit function with respect to the price, we can find the rate of change of the profit:
dProfit/dp = dx/dp×p + x(p)
= -400 p + 400 ( 30) + 2000 - 400(p - 30)
= -400 p + 12000
When p = 30, the rate of change of the profit is:
dProfit/dp = -400(30 )+ 12000
= 3600
So the rate of change of the profit when the item price is $30 is $3600 per dollar increase in price.
Hence, the rate of change of the profit when the item price is $30 is $3600 per dollar increase in price.

A child is flying a kite. If the kite is "h" feet above the child's hand level and the wind is blowing it on a horizontal course at "v" feet per second, the child is paying out cord at _____ feet per second when "s" feet of cord are out. Assume that the cord remains straight from hand to kite.
The child is paying out cord at a rate of s(ds/dt)) /√(s²-h²) feet per second when "s" feet of cord are out.
What is Differential equation?A differential equation is an equation that contains one or more functions with its derivatives.
The distance between the kite and the child's hand level "d".
By using the Pythagorean theorem, we can write:
d² + h² = s²
Simplifying and solving for d, we get:
d² = s²-h²
d = √(s²-h² )
Let's call the length of the cord "L". Then, we can write:
d² + L² = s²
Differentiating both sides with respect to time (t), we get:
2d (dd/dt) + 2L (dL/dt) = 2s (ds/dt)
We want to find (dL/dt) when L = s and d = √(s²-h² )
(dd/dt) = 0 as the height of the kite above the child's hand level is constant.
(dL/dt) = (s(ds/dt) - d (dd/dt)) / L
Substituting in the values we found for d and L, we get:
(dL/dt) = s(ds/dt)) / √(s²-h² )
Therefore, the child is paying out cord at a rate of s(ds/dt)) /√(s²-h²) feet per second when "s" feet of cord are out.

A house that costs $200,000 will appreciate in value by 3% each year.
Write a function that models the cost of the house over time. Use x for years and y for
the value of the house, in dollars.
Find the value of the house at the end of ten years.
Answer: The function that models the cost of the house over time can be written as y = 200,000 * (1 + 0.03)^x, where x is the number of years and y is the value of the house.
To find the value of the house at the end of ten years, we need to plug in x = 10 into the function:

Find the volume of a frustum of a pyramid with square base of side 22, square top of side 13 and height 20.
The volume of a frustum of a pyramid with given dimensions is 6260 cubic units.
What is frustum of pyramid?
The top of a conventional pyramid is removed to create the frustum, which is a pyramid. It is known as a truncated pyramid for this reason. The height of a pyramid is represented by the letter h and is the distance from its base to its summit. Similar to it, it has two bases and a slant height indicated by the letter "s" (top and bottom).
We are given frustum of a pyramid with square base of side 22, square top of side 13 and height 20.
We know that volume of frustum of pyramid(V) = h(b^2 + a^2 + ab)/3
We are given b = 22, a = 13 and h = 20
From this, we get
⇒V = h(b^2 + a^2 + ab)/3
⇒V = 20(22^2 + 13^2 + 22*13)/3
⇒V = 20(484 + 169 + 286)/3
⇒V = 20(939)/3
⇒V = 20*313
⇒V = 6260 cubic units
Hence, the volume of a frustum of a pyramid with given dimensions is 6260 cubic units.

After evaluating these expression it seems to be the option (a) math.hypot(3,4) == math.sqrt(25) evaluate that is True
The math.hypot function calculates the Euclidean distance between two points in a 2D space, which is equivalent to the length of the hypotenuse of a right triangle with sides of length a and b (where a and b are the arguments to math.hypot).
In this case, math.hypot(3, 4) calculates the length of the hypotenuse of a right triangle with sides of length 3 and 4, which is equal to 5.
The expression math.sqrt(25) calculates the square root of 25, which is equal to 5. Since math.hypot(3, 4) and math.sqrt(25) both evaluate to 5, the expression math.hypot(3, 4) == math.sqrt(25) evaluates to True.

when constructing bins for a frequency distribution of quantitative data, which of the following principles should generally be followed?
When constructing bins for a frequency distribution, it is important to have equal widths, choose the number of bins based on the sample size, and consider outliers in the data.
A frequency distribution is a representation of data that shows the number of observations in each category or bin.
One of the most important principles is to have an equal number of observations in each bin. This is known as having equal widths for the bins.
To calculate the width of a bin, divide the range of the data by the number of bins desired. The range is then divided into equal parts, each of which becomes a bin width.
Another principle is to have the number of bins chosen based on the sample size.
A rule of thumb is to have at least five observations in each bin, but more bins may be necessary for larger samples.
Additionally, the choice of bin width can also be influenced by outliers in the data. If there are extreme values in the data, it may be necessary to create a separate bin for those values, so they do not dominate the frequency distribution.

Of the lists of properties you provided, only the list of "identity, solubility, melting point" contains only those that are characteristic properties of a substance.
Identity refers to the name or chemical formula of the substance, which is unique to that substance and can be used to identify it.
Solubility refers to the ability of a substance to dissolve in a solvent, such as water. The solubility of a substance can also be used to identify it, as different substances have different solubility's.
Melting point refers to the temperature at which a solid substance will change into a liquid. Like solubility, the melting point of a substance is also a characteristic property that can be used to identify it.
On the other hand, boiling point, mass, and density are not always characteristic properties of a substance. While they can give us information about a substance, they are not unique to that substance and cannot be used to identify it.
Volume and temperature are not considered characteristic properties of a substance, as they are dependent on external factors, such as the pressure and the amount of the substance being measured.

The equation 38.2 + (-1) = 11 is not true for any value of x. There is no solution for this equation.
Oh, hello there! Let's work on this equation together.
38.2 + -1 = 11
Let's create a table to keep track of our work.
-1 38.2 11
+1 37.2 12
As you can see, we added 1 to both sides to cancel out the negative 1.
So now, our equation is 37.2 = 12.
Let's subtract 12 from both sides.
-12 37.2 11
-12 25.2 -1
And there you have it! The solution is 25.2.
I hope this helps!
A tower that is 118 feet tall casts a shadow 130 feet long. Find the angle of elevation of the sun to the nearest degree.
Answer:
42°
Step-by-step explanation:
A right-angled triangle can formed in this scenario (image attached), where:
θ = angle of elevation of the sun
Opposite side = The height of the tower
Adjacent side = Length of the shadow
Trigonometric function will be used to determine the angle of elevation:
tanθ = [tex]\frac{opposite}{adjacent}[/tex]
[tex]= \frac{118 feet}{130 feet}[/tex]
feet in the numerator and denominator will cancel each other out completely:
θ =[tex]tan^{-1} (\frac{118}{130})[/tex]
θ = 42.23°
∴ θ = 42° (Rounded to the nearest degree)
