Answer:
[tex]40%[/tex]%
Step-by-step explanation:
Okay, so percent error is how we determine the margin of differentiation or in simple terms, the percent of the difference between two numbers. The equation is as follows:
[tex]\frac{Accurate Amount-GivenAmount}{Accurate Amount}[/tex]
So, here we know that our Accurate Amount is $180 since that is the price of the phone. Our given amount is $108 dollars, so our steps would look like this:
[tex]\frac{Accurate Amount-GivenAmount}{Accurate Amount} \\\\\frac{180-108}{180} =\\\\\frac{72}{180} =\\\\0.4 or 40%[/tex]
I would be happy to help you again in the future and hope that this provided you with some clarification. Have a good day! :D

If represents the number of bacteria in a culture at time t, how many will there be at time
Answers
Answer:
Population of bacteria at time [tex]t = 6[/tex] is [tex]2441[/tex]
Step-by-step explanation:
The complete question is
If [tex]y = 10 (2.5)^t[/tex]represents the number of bacteria in a culture at time t, how many will there be at time [tex]t = 6[/tex]
Solution
Given
The population of bacteria after time t is equal to [tex]y = 10 (2.5)^t[/tex]
Population when at time [tex]t = 6[/tex]
We will substitute the value of time in above equation.
[tex]y = 10 (2.5)^6\\y = 10 *244.14\\y = 2441.4 = 2441[/tex]

the line containing the points (-3,k) and (4,8) is parallel to the line containing the points (5,3) and (1,-6) what is the value of k ?
Answers
Answer:
The value of k is:
[tex]k=-\frac{31}{4}[/tex]
Step-by-step explanation:
Given
The line containing the points (-3,k) and (4,8) is parallel to the line containing the points (5,3) and (1,-6).
To determine
what is the value of k?
To determine the value of k, the first step we need to do is to find the slope of the line containing the points (5,3) and (1,-6) using the formula
[tex]\mathrm{Slope}=m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Here:
[tex]\left(x_1,\:y_1\right)=\left(5,\:3\right)[/tex][tex]\left(x_2,\:y_2\right)=\left(1,\:-6\right)[/tex]now substituting (x₁, y₁) = (5, 3) and (x₂, y₂) = (1, -6) in the formula
[tex]m=\frac{-6-3}{1-5}[/tex]
[tex]m=\frac{-9}{-4}[/tex]
Apply the fraction rule: [tex]\frac{-a}{-b}=\frac{a}{b}[/tex]
[tex]m=\frac{9}{4}[/tex]
Thus, we conclude that the slope of the line containing the points (5,3) and (1,-6) will be:
[tex]m=\frac{9}{4}[/tex]
Importing Tip:
We know that the parallel lines have the same slopes, so the slope of the line containing the points (-3,k) and (4,8) will also be 9/4.Thus, using the slope formula for the line containing the points (-3,k) and (4,8).
[tex]\mathrm{Slope}=m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Here:
[tex]\left(x_1,\:y_1\right)=\left(-3,\:k\right)[/tex][tex]\left(x_2,\:y_2\right)=\left(4,\:8\right)[/tex]As we know that the parallel lines have the same slopes.
Thus, the second step we need to do is to substitute m = 9/4 in the slope formula
[tex]\frac{9}{4}=\frac{y_2-y_1}{x_2-x_1}[/tex]
now substituting (x₁, y₁) = (-3, k) and (x₂, y₂) = (4, 8) in the formula
[tex]\:\:\:\frac{9}{4}=\:\frac{8-k}{4-\left(-3\right)}[/tex]
switch sides
[tex]\frac{8-k}{4-\left(-3\right)}=\frac{9}{4}[/tex]
Multiply both sides by 7
[tex]\frac{7\left(8-k\right)}{4-\left(-3\right)}=\frac{9\cdot \:7}{4}[/tex]
Simplify
[tex]8-k=\frac{63}{4}[/tex]
Subtract 8 from both sides
[tex]8-k-8=\frac{63}{4}-8[/tex]
Simplify
[tex]-k=\frac{31}{4}[/tex]
Divide both sides by -1
[tex]\frac{-k}{-1}=\frac{\frac{31}{4}}{-1}[/tex]
Simplify
[tex]k=-\frac{31}{4}[/tex]
Therefore, the value of k is:
[tex]k=-\frac{31}{4}[/tex]
VERIFICATION:
As the value of k = -31/4.
So the first line will contain the points:
(-3, -31/4)(4, 8)Finding the slope between (-3, -31/4) and (4, 8) using the slope formula
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
Here:
[tex]\left(x_1,\:y_1\right)=\left(-3,\:-\frac{31}{4}\right)[/tex][tex]\left(x_2,\:y_2\right)=\left(4,\:8\right)[/tex]so substituting (x₁, y₁) = (-3, -31/4) and (x₂, y₂) = (4, 8) in the formula
[tex]m=\frac{8-\left(-\frac{31}{4}\right)}{4-\left(-3\right)}[/tex]
Apply rule: [tex]-\left(-a\right)=a[/tex]
[tex]m=\frac{8+\frac{31}{4}}{4+3}[/tex]
Add the numbers: [tex]4+3=7[/tex]
[tex]m=\frac{8+\frac{31}{4}}{7}[/tex]
[tex]m=\frac{\frac{63}{4}}{7}[/tex] ∵ [tex]8+\frac{31}{4}=\frac{63}{4}[/tex]
Apply fraction rule: [tex]\frac{\frac{b}{c}}{a}=\frac{b}{c\:\cdot \:a}[/tex]
[tex]m=\frac{63}{4\cdot \:7}[/tex]
[tex]m=\frac{63}{28}[/tex]
Cancel the common factor: 7
[tex]m=\frac{9}{4}[/tex]
So, the slope of the line containing the points (-3,k) and (4,8) is m = 9/4. It means both lines have the same slopes. Hence, they are parallel.
Therefore, we conclude that the value of k = -31/4 is true.

Step-by-step explanation:
The imaginary root has a corresponding conjugate that is also a root. Each root has a corresponding factor: (x -p) for root p.
f(x) = (x -3i)(x +3i)(x -(-1))(x -2)
f(x) = (x^2 +9)(x^2 -x -2) . . . . combine pairs of factors

Apple, carrot, and celery juices are mixed in a ratio 3 : 1 : 2. The amount of appe juice is 33 millimeters.
a) How much more apple juice is used in the mixture than carrot juice?
b) What is the total amount of the mixture?
Answers
Answer:
A) 3 times more apple juice is used than carrot juice aka 22 more millimeters
B) 66 millimeters
Step-by-step explanation :
3 : 1 : 2 aka 33 : 11 : 22
You have the ratio, so you just have to divide 33/3 and you know you have to multiply that awnser times the other ratios.
So...
33/3 = 11
3 x 11 = 33
1 x 11 = 11
2 x 11 = 22
So the ratio is 33 : 11 : 22
Then, A is asking you how much more apple juice than carrot juice, so subtract ( amount of apple juice - amount of carrot juice )
33 - 11 = 22 millimeters more apple juice than carrot juice
Then, B is asking you how much juice is there in total. So just add all the juices together....
33+22+11 = 66
So 66 milimeters of juice all together
(a) The apple juice is 22 ml more than the carrot juice.
(b) The total amount of the mixture is 66 ml.
Ratio:Important information:
The ratio of Apple, carrot, and celery is 3 : 1 : 2.Amount of apple juice is 33 ml.(a)
Let the quantity of Apple, carrot, and celery is 3x, x, 2x respectively.
[tex]3x=33[/tex]
[tex]x=11[/tex]
Difference between Apple and carrot juice is:
[tex]3x-x=2x[/tex]
[tex]3x-x=2(11)[/tex]
[tex]3x-x=22[/tex]
Therefore, the apple juice is 22 ml more than the carrot juice.
(b)
The total amount of the mixture is:
[tex]3x+x+2x=6x[/tex]
[tex]3x+x+2x=6(11)[/tex]
[tex]3x+x+2x=66[/tex]
Therefore, the total amount of the mixture is 66 ml.
