a cylindrical can needs to have a volume of 6 cubic inches a label is to go around the side of the can. The function S(r)=12/r gives the area of the label in square inches where r is the radius of the can in inches
Answer:
Following are the solution to this question:
Step-by-step explanation:
Please find the complete question in the attachment.
Cylinder volume V= 6 Cubes - inch

Joelle wants to place an oversized image which is 30.51 cm wide so that it appears centered on the page. The width of the page is 21.59 cm. In the program, horizontal positions to the right of the leftmost edge of the page are positive. What horizontal position for the left edge of the image should Joelle use to center the image?
-4.46cm
Step-by-step explanation:
The horizontal midpoint of the page is;
The horizontal midpoint of the image is given as;
For the image to be centered, these to midpoints must be on the same point in the axis.
If we take the leftmost edge of the paper to be point zero on the axis, then, the distance accommodated by the paper is 10.795cm. The distance that goes beyond this leftmost edge is computed as;
On the axis, this is on the negative side. Therefore, the horizontal position for the left edge of the image that Joelle should use to center the image is -4.46cm.

Equality PropertiesSolving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
a + 4b = -4
a + 10b = -16
Step 2: Rewrite Systems
a + 4b = -4
Subtract 4b on both sides: a = -4 - 4bStep 3: Redefine Systems
a = -4 - 4b
a + 10b = -16
Step 4: Solve for b
Substitution
Substitute in a: -4 - 4b + 10b = -16Combine like terms: -4 + 6b = -16Isolate b term: 6b = -12Isolate b: b = -2Step 5: Solve for a
Define equation: a + 4b = -4Substitute in b: a + 4(-2) = -4Multiply: a - 8 = -4Isolate a: a = 4---
82%There are 24 students in a class.
8 of the students are boys.
b)
a)
Write the amount of boys in the class as a fraction in its simplest form.
b)
Write the amount of girls in the class as a fraction in its simplest form.
Answer:
Boys: 1/3
Girls: 2/3
Step-by-step explanation:
There are 8 boys in the class out of 24 students.
The fraction will be 8/24. Both the numerator and the denominator are divisible by 8.
8 ÷ 8 = 1
24 ÷ 8 = 3
The simplest form will be 1/3.
There are 16 girls in the class because 24 - 8 = 16.
The fraction will be 16/24. Both numbers are divisible by 8.
16 ÷ 8 = 2
24 ÷ 8 = 3
The simplest form will be 2/3.

First term: 2 3/4 sixth term: 3 7/12 what is the rule
Answer:
we conclude that the rule will be:
[tex]a_n=\frac{31}{12}+\frac{1}{6}n[/tex]
Step-by-step explanation:
Given
[tex]a_6=3\frac{7}{12}=\frac{43}{12}[/tex]
[tex]a_1=2\frac{3}{4}=\frac{11}{4}[/tex]
We know the arithmetic sequence with the common difference is defined as
[tex]a_n=a_1+\left(n-1\right)d[/tex]
where a₁ is the first term and d is a common difference.
so
a₆ = a₁ + (6-1) d
substituting a₆ = 43/12 and a₁ = 11/4 to determine d
[tex]\frac{43}{12}=\:\frac{11}{4}\:+\:5d[/tex]
switch sides
[tex]\frac{11}{4}+5d=\frac{43}{12}[/tex]
subtract 11/4 from both sides
[tex]\frac{11}{4}+5d-\frac{11}{4}=\frac{43}{12}-\frac{11}{4}[/tex]
[tex]5d=\frac{5}{6}[/tex]
Divide both sides by 5
[tex]\frac{5d}{5}=\frac{\frac{5}{6}}{5}[/tex]
[tex]d=\frac{1}{6}[/tex]
as
a₁ = 11/4
[tex]d=\frac{1}{6}[/tex]
Therefore, the nth term of the Arithmetic sequence will be:
[tex]a_n=a_1+\left(n-1\right)d[/tex]
substituting d = 1/6 and a₁ = 11/4
[tex]a_n=\frac{11}{4}+\left(n-1\right)\frac{1}{6}[/tex]
[tex]=\frac{11}{4}+\frac{1}{6}n-\frac{1}{6}[/tex]
[tex]=\frac{31}{12}+\frac{1}{6}n[/tex]
Therefore, we conclude that the rule will be:
[tex]a_n=\frac{31}{12}+\frac{1}{6}n[/tex]
If an independent-measures design is being used to compare two treatment conditions, then how many different groups of participants would be needed and how many scores would there be for each participant
Answer:
2 groups and 1 score for each participant
Step-by-step explanation:
An independent measures design is a defined as a research method whereby multiple experimental groups are examined and the participants will only be in one group. Now, each participant will only be affected by one condition of the independent variable during the experiment.
In the question given, we want to use the method I just described to compare two treatment conditions.
This means that there will be two groups and each participant in both groups will be assigned one score.

Given the expression
2m/2m+3 - 2m/2m-3 = 1
Find the LCM of the expression at the left hand side:
2m(2m-3)-2m(2m+3)/(2m+3)(2m-3) = 1
open the bracket
4m²-6m-4m²-6m/(4m²-9) = 1
Cross multiply
4m²-6m-4m²-6m = 4m² - 9
-12m = 4m² - 9
4m² - 9+12m = 0
4m² +12m-9 = 0
Since the resulting equation is a quadratic equation, it will have 2 solutions since the degree of the equation is 2
