Natasha is observing the growth of a population of bacteria. She started out with 250 bacteria cells. The population of bacteria quadruples every hour. Use x to represent the number of hours and y to represent the population of the bacteria. Enter an equation that represents this scenario in the box.
Answer:
[tex]y=250(5)^x[/tex]
Step-by-step explanation:
The growth of a population of bacteria can be represented by exponential growth function,
[tex]y=a(1+r)^x[/tex]
where,
y = the population of the bacteria after x hours,
x = the number of hours,
a = initial population of bacteria,
r = rate of growth,
At the beginning the number bacteria was 250 and the population of bacteria quadruples every hour i.e rate of growth is 400% or 4 per hour.
Putting all the values,
[tex]y=250(1+4)^x[/tex]
[tex]\Rightarrow y=250(5)^x[/tex]

Answer:
Step-by-step explanation:
Given that a storage rack has dimensions as 25x12x5 ft.
Box has dimensions as 15x8x10 inches
Volume of each box = 15(8)(10) = 1200 inches = 1200x12^(-3) feet^3
Volume of 5000 boxes = 5000 (1200x12^(-3) ) = 3472.22 cubic feet
Volume of storage rack = 25(12)(5) = 1500 cubic feet
Volume of 25 storage racks 1500(25) = 37500 cubic feet.
SInce storage racks have sufficient volume it is concluded that enough storage is there.
Answer:
Yes, we have enough storage space.
Step-by-step explanation:
25 storage racks that are:
Length: Lsr = 25 ft = 25 ft (12 in / 1 ft) → Lsr = 300 in
Width: Wsr = 3 ft = 3 ft (12 in / 1 ft) → Wsr = 36 in
Height: Hsr = 12 ft = 12 ft (12 in / 1 ft) → Hsr = 144 in
5000 boxes 15x8x10 in
Length: Lb = 15 in
Width: Wb = 8 in
Height: Hb = 10 in
In the length of each storage rack we can put:
Nl=Lsr/Lb=300 in / 15 in → Nl = 20
In the width of each storage rack we can put:
Nw=Wsr/Wb=36 in / 8 in = 4.5 → Nw = 4
In the height of each storage rack we can put:
Nh=Hsr/Hb=144 in / 10 in = 14.4 → Nh = 14
Then we can put in each storage rack:
N = Nl Nw Nh = (20)(4)(14) → N=1,120 boxes
And we have 25 storage racks, then we can storage in total:
Nt=25N=25(1,120)→Nt=28,000 boxes
And we have 5,000 boxes, then we have enough storage space
Solve using substitution
x=2y-6
y= -3x+17
Answer:
(x, y) = (4, 5)
Step-by-step explanation:
given the 2 equations
x = 2y - 6 → (1)
y = - 3x + 17 → (2)
Either substitute x = 2y - 6 into (2) or y = - 3x + 17 into (1)
substituting y = - 3x + 17 into (1)
x = 2(- 3x + 17) - 6
x = - 6x + 34 - 6
x = - 6x + 28 ( add 6x to both sides )
7x = 28 ( divide both sides by 7 )
x = 4
substitute x = 4 into (2)
y = - 12 + 17 = 5
solution is (4, 5 )
Divide (x^3-8x^2+17x-10)/(x-5)
Answer:
(x - 2)*(x - 1) is the answer
Step-by-step explanation:
We have to divide the polynomial f(x) = x^{3}-8x^{2}+17x-10 by (x-5).
Now, after dividing f(x) gets simplified into (x-5)*(x^{2}-3x+2).
So, we need to factorize the quadratic equation x^{2}-3x+2.
i.e. x^{2} - 3x + 2 = x^{2} - x - 2x + 2 = x(x-1) - 2(x-1) = (x - 2)*(x - 1)
Therefore, f(x) again gets simplified into (x-5)*(x - 2)*(x - 1)
Now eliminating the common factor (x-5).
We get, [tex]\frac{x^{3}-8x^{2}+17x-10}{x-5}[/tex] = (x - 2)*(x - 1)
Answer:
[tex]x^{2}-3x+2[/tex]

crate a list of steps, in order, that will solve the following equation. 2(x+3/4)^2 -5 =123
Answer:
x = -8.75; x = 7.25
Step-by-step explanation:
2(x + ¾)² - 5 = 123
Add 5 to each side: 2(x+ ¾)² = 128 Divide each side by 2: (x+ ¾)² = 64 Take the square root of each side: x + ¾ = 8 x + ¾ = -8 Subtract ¾ from each side: x = 8 - ¾ x = -8 - ¾ Convert to decimal fraction: x = 8 - 0.75 x = -8 – 0.75 Subtract: x = 7.25 x = -8.75The graph of your equation is a parabola with x-intercepts at x = -8.75
and x = 7.25.
The list of steps, in order, that will solve the equation is:
Addition of 5 to both sides to eliminate the value of -5Division of both sides of the equation by 2 to eliminate the coefficient of 2 from the left-hand sideTaking the square root of both sidessubtract 3/4 from each sideConvert the answer to decimalThe given expression is raised to a power of 2, so we can say that the given expression is a quadratic equation.
What is a quadratic equation?A quadratic equation is a form of an algebraic expression in which the variable is usually raised to the power of its second degree.
From the parameters given:
[tex]\mathbf{2(x + \dfrac{3}{4})^2 -5 = 123 }[/tex]
Addition of +5 to both sides[tex]\mathbf{2(x + \dfrac{3}{4})^2 -5 +5 = 123+5 }[/tex]
[tex]\mathbf{2(x + \dfrac{3}{4})^2 = 128}[/tex]
Division of both sides by 2[tex]\mathbf{\dfrac{2(x + \dfrac{3}{4})^2 }{2} =\dfrac{ 128}{2}}[/tex]
[tex]\mathbf{(x + \dfrac{3}{4})^2 = 64}[/tex]
Taking the square root of both sides[tex]\mathbf{\sqrt{(x + \dfrac{3}{4})^2} =\sqrt{ 64}}[/tex]
[tex]\mathbf{(x + \dfrac{3}{4})} =\pm8}[/tex]

Alicia runs for exercising falicia runs 8 Miles and 6 days how many days will it take for her to run 36 miles
Alicia runs 8 miles in 6 days. By setting up a proportion, it's calculated that it will take her 27 days to run 36 miles at the same rate.
Calculating Days Needed to Run a Total Distance:
Alicia runs 8 miles in 6 days. To find out how many days it will take her to run 36 miles, we can set up a proportion. Since the number of days is directly proportional to the miles run, we can use the equation:
8 miles / 6 days = 36 miles / x days
By cross-multiplying, we get:
8 miles * x days = 6 days * 36 miles
x = (6 days * 36 miles) / 8 miles
The miles cancel out, leaving us with:
x = 216 / 8
x = 27 days
Therefore, it will take Alicia 27 days to run a total of 36 miles if she continues running at the same rate.

You are making sets of pens and pencils to sell. You want each set to contain the same combination of pens and pencils. You have 28 pens and 80 pencils, and you want to use them all. What is the greatest number of these sets you can make?
The greatest number of sets of pens and pencils that can be made, using all of the given 28 pens and 80 pencils in each set, is 4. Each set would contain 7 pens and 20 pencils.
Explanation:In the problem, we are looking to find the Greatest Common Divisor (GCD), which is the greatest number that can evenly divide both the number of pens (28) and the number of pencils (80). The GCD between 28 and 80 is 4.
Thus, the most sets of pens and pencils you can make would be equal to the GCD, which in this case is 4.
This means you can put together 4 sets with an equal number of pens and pencils in each set. In each of these sets, there would be 7 pens (28 pens ÷ 4 sets) and 20 pencils (80 pencils ÷ 4 sets).

A plane travels at a constant speed. It takes 6 hours to travel 3,360 miles
To find the average speed of the plane, divide the total distance traveled, which is 3,360 miles, by the total time of the journey, which is 6 hours, resulting in an average speed of 560 miles per hour.
Explanation:The student's question involves calculating average speed, which is a concept in Physics, specifically within the topic of kinematics. To find the average speed of the plane you would use the formula:
average speed = total distance / total time
In this case, the plane travels 3,360 miles in 6 hours, so the calculation would be:
average speed = 3,360 miles / 6 hours = 560 miles/hour
This calculation demonstrates how to determine the average speed of an object in motion when given the total distance traveled and the total time taken. This concept is analogous to determining the average speed in other examples, such as a car journey or a train trip.

Marie mixes 16 liters of 18% acid solution with a 27% acid solution, which results in 21% acid solution. Let x represent the number of liters of 27% solution used and let y represent the number of liters of mixture. Which system of equations can be used to find the number of liters of 27% acid solution in the mixture?
1. y = x + 16; 0.27y = 0.21x + 2.88
2. y = x + 16; 0.21y = 0.27x + 2.88
3.y = x + 16; 0.21y = 0.27x + 4.32
4. y = x + 16; 0.27y + 2.88x = 0.21
Answer:
2. y = x + 16; 0.21y = 0.27x + 2.88
Step-by-step explanation:
You have two conditions:
Volume of 18 % + volume of 27 % = volume of 21 % Mass of acid in 18 % + mass of acid in 27% = mass of acid in 21 %For the first condition,
16 + x = y Transpose
(1) y = x + 16
=====
For the second condition
V₁c₁ + V₂c₂ = V₃c₃
16×0.18 + 0.27x = 0.21y
2.88 + 0.27x = 0.21y Transpose
(2) 0.21y = 0.27x + 2.88
The system of equations is y = x + 16; 0.21y = 0.27x + 2.88

At the art fair, 95 artists exhibited their work. Of those 95 artists, 25 showed sculptures and 48 showed paintings. If 12 showed both sculptures and paintings, how many artists showed only sculptures or paintings?
To determine the number of artists who showed only sculptures or paintings at the art fair, we use the formula for the principle of inclusion-exclusion, resulting in 61 artists.
Explanation:To find out how many artists showed only sculptures or paintings at the art fair, we apply the principle of inclusion-exclusion. First, we add the number of artists who showed sculptures (25) to those who showed paintings (48), which gives us a total of 73 artists. However, this counts the 12 artists who showed both sculptures and paintings twice, so we subtract 12 from this total to correct for the double counting. Therefore, the number of artists who showed only sculptures or paintings is 73 - 12, which equals 61 artists.
