Answer:
the next year population is 122,689
Step-by-step explanation:
The computation of the next year population is as follows:
= This year population × increase percentage
= 119,000 × (1 + 0.031)
= 119,000 × 1.031
= 122,689
Hence, the next year population is 122,689
The above formula is applied so that the correct value of the population could come

A right rectangular prism has edges of 8 feet, 4 feet, and 1/2 foot. How many cubes with side lengths of 1/2 foot would be needed to fill the prism?
Answer:
Step-by-step explanation:
From the question we are told that
Edges of 8 feet, 4 feet, and 1/2 foot
Generally the volume V_p of the right rectangular prism is mathematically represented as
[tex]V_p=8*4*0.5[/tex]
[tex]V_p=16[/tex]
Generally volume of the cube V_c is mathematically given as
[tex]V_c =(\frac{1}{2})^3[/tex]
[tex]V_c =\frac{1}{6}[/tex]
Therefore total number of cubes is given as
[tex]V=\frac{V_p}{V_c}[/tex]
[tex]V=\frac{16}{\frac{1}{6}}[/tex]
[tex]V=96[/tex]

Un comerciante compro un lote de 15 calculadoras a 40 dolares cada una .Vendio 5 de ellas ,a orecio de promoción por100 dolares .Calcula el precio de venta de cada una de las restantes calculadoras para que gane 150 en la operación
The selling price of each of the remaining calculators should be $65 so that the merchant makes a profit of $150 in the entire operation.
The merchant bought a batch of 15 calculators at $40 each, so the total cost of the batch is:
Cost price = 15 calculators × $40/calculator
= $600
The merchant sold 5 calculators at a promotional price of $100 each.
So, the revenue from selling these 5 calculators is:
Revenue = 5 calculators × $100/calculator
= $500
Now, we need to calculate the profit made from the sale of these 5 calculators:
Profit = Revenue - Cost price
Profit = $500 - $600
= -$100 (Negative because the merchant incurred a loss on these 5 calculators)
The merchant wants to make a profit of $150 in the entire operation. So, adding the profit from selling the first 5 calculators:
Desired profit = $150
Current profit = -$100
Additional profit needed = Desired profit - Current profit
Additional profit needed = $150 - (-$100)
= $250
The merchant has 15 - 5 = 10 calculators left to sell.
We need to distribute the additional profit of $250 among the remaining 10 calculators:
Additional profit per calculator = Additional profit needed / Number of remaining calculators
Additional profit per calculator = $250 / 10 calculators
= $25
Now, let's calculate the selling price of each of the remaining calculators:
Selling price = Cost price + Additional profit per calculator
Selling price = $40 + $25 = $65
So, the selling price of each of the remaining calculators should be $65.

A cylindrical tank with radius 3m is being filled with water at a rate 4m^³/min.How fast is the height of the water increasin?
Given :
A cylindrical tank with radius 3m is being filled with water at a rate 4m³/min.
To Find :
How fast is the height of the water increasing.
Solution :
We know, volume of cylinder is given by :
[tex]V = \pi r^2h[/tex] ....1)
Also, we have given that, [tex]\dfrac{dV}{dt} = 4 \ m^3/min[/tex] .
Differentiating equation 1) w.r.t t we get :
[tex]\dfrac{dV}{dt} =3^2 \pi \dfrac{ dh }{dt}\\\\\dfrac{dh}{dt} = \dfrac{4}{3^2 \times \pi}\\\\\dfrac{dh}{dt} = 0.141 \ m/min[/tex]
Therefore, the height of water is increasing at a rate of 0.141 m/min.
Jaclyn has $120 saved and earns $40 each month in allowance. Pedro has $180 saved and earns $20 a month in allowance.
If they both save their entire allowances, how long will it take before Jaclyn and Pedro have saved the same amount of money?
Enter your answer in the box.
Answer:
3 months
Step-by-step explanation: Let after m months they saved same amount of money.
Given,
Saving of Jaclyn = $ 120,
Amount earned by him/her per month = $ 40,
So, the total amount contained by him/her in m months = Saving + earning for m months
= 120 + 40m,
Similarly, saving of Pedro = $ 180,
Amount earned by him/her per month = $ 20,
So, the total amount contained by him/her in m months = 180 + 20m
Thus, we can write,
120 + 40m = 180 + 20m
40m = 180 + 20m - 120
40m - 20m = 60
20m = 60
⇒ m = = 3.
Hence, it will take 3 months before which Jaclyn and Pedro have saved the same amount of money.

The domain of f(x) is [4, 5, 6]. If f(x) = 3x + 2, what is the range?
Answer:
The range of the function is:
Range R = {14, 17, 20}
Step-by-step explanation:
Given the function
[tex]f(x) = 3x + 2[/tex]
We also know that range is the set of values of the dependent variable for which a function is defined.
In other words,
Range refers to all the possible sets of output values on the y-axis.We are given that the domain of the function is:
Domain D = {4, 5, 6}
Now,
substituting x = 4 in the function
f(4) = 3(4) + 2
f(4) = 12 + 2
f(4) = 14
substituting x = 5 in the function
f(5) = 3(5) + 2
f(5) = 15 + 2
f(5) = 17
substituting x = 6 in the function
f(6) = 3(6) + 2
f(6) = 18 + 2
f(6) = 20
Thus, we conclude that:
at x = 4, y = 14
at x = 5, y = 17
at x = 6, y = 20
Thus, the range of the function is:
Range R = {14, 17, 20}
