Answer:
The diameter is 7.6 cm
Step-by-step explanation:
Mathematically, the volume of a cylinder can be calculated using the formula;
V = pi * r^2 * h
From the question;
V = 900
r = ?
h = 20
Substituting these values
900 = 3.142 * r^2 * 20
r^2 = (900)/(3.142 * 20)
r^2 = 14.32
r = √14.32
r = 3.78 cm
Mathematically, the diameter is 2 times the radius
We have this as;
2 * 3.78 = 7.6 cm

Which of these r-values represents the strongest correlation? O A. -0.7 Caty B. -0.6 O C. -0.4 O D. -0.5
Answer:
-0.4
Step-by-step explanation:
its that one
The strongest correlation is -0.4.
Option C is correct.
What is correlation?Correlation is a statistical term that expresses how closely two variables are related linearly (meaning they change together at a constant rate). It's a typical tool for describing simple relationships without stating a cause and effect link.
When the result is closer to +1 (positive correlation) or -1 (negative correlation), the strongest correlation is considered (negative correlation).
A positive correlation coefficient means that the value of one variable is directly related to the value of another.
Here -0.4 is the closest value to 1.
So, the strongest correlation is -0.4.

B)
miles per gallon
27
09
27 miles per gallon
D)
54 miles per gallon
Answer:
The unit rate = 27 miles per gallon.
Hence, option C is true.
Step-by-step explanation:
From the given line graph:
Taking two points
(2, 54)(6, 162)The unit rate can be determined by finding the rate of change or slope between the points (2, 54) and (6, 162)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(2,\:54\right),\:\left(x_2,\:y_2\right)=\left(6,\:162\right)[/tex]
[tex]m=\frac{162-54}{6-2}[/tex]
Refine
[tex]m=27[/tex]
Therefore, the unit rate = 27 miles per gallon.
Hence, option C is true.

Answer:
1. First choice
2. Image C
3. Fourth chioice
4. Third choice
5. First choice.
Step-by-step explanation:
First ScreenshotSolve the equation.
[tex] {x}^{2} - 9 = 0[/tex]
Use the difference of two squares formula.
[tex] {x}^{2} - {y}^{2} = (x + y)(x - y)[/tex]
[tex](x + 3)(x - 3) = 0 \\ x = 3, - 3[/tex]
Second ScreenshotA linear relationship already says it all. Find the graph that is NOT a curve. The only image that is not a curve and the graph straight forwards is the Image C aka A choice.
Third ScreenshotA nonlinear function is a function that does not have a straight line graph. All linear functions are linear, except for Quadratic and up. Every polynomial function with the degree greater than one wont be a linear.
Fourth Screenshot[tex]y = x + 3[/tex]
If we change the constant from 3 to 5 then we would get
[tex]y = x + 5[/tex]
The graph would shift up 2 units.
Last ScreenshotThe second and third graph both are function. We can tell by doing a line test. Simply draw a vertical line first. Then we check if the line intercepts the graph more than a point or not.
If the line intercepts more than a point then it is not a function.
If the line intercepts only a point then it is a function.

Step 1: Let's solve first so we can order it later.
[tex]24a-6a+15=51\\18a+15=51\\-15 -15\\\18a=36\\\\[/tex]
Divide 18 both sides.

Ok so we have everything solved answer: a=2.
Now we need to order.
Step 1. Distribute 3.
Step 2. Combine like terms 24a and 6a.
Step 3. Subtract 15 from both sides.
Step 4. Divide both sides by 18.

Bryan spent 14 minutes on the phone while routing 7 phone calls. How many phone cells does Bryan have to route to spend a total of 16 minutes on the phone? Solve using unit rates.
Answer:
8 phone cells
Step-by-step explanation:
We are told that he spent 14 minutes on the phone while routing 7 phone calls.
Now, we want to find the number of phone cells he will route for a total of 16 minutes.
Thus, by proportion using unit rates;. Number of minutes spent pet phone cell = 14 minutes ÷ 7 phone calls = 2 minutes per phone cell
Therefore, for 16 minutes, number of phone cells will be;
16 minutes ÷ 2 minutes per phone cell = 8 phone cells

How were greek city states formed
Answer:
Greek city-states likely developed because of the physical geography of the Mediterranean region. The landscape features rocky, mountainous land and many islands.

If ΔABC is an equilateral triangle with, AB = 2x + 17, BC = 6x - 19, AC = 4x-1, find x and the measure of each side
Answer:
[tex]x=9, AB=BC=AC=35[/tex]
Step-by-step explanation:
Equilateral triangles have 3 congruent sides, so all 3 sides have the same length. Therefore, we know that [tex]AB=BC=AC[/tex]. We are given the lengths of all 3 sides in terms of [tex]x[/tex], but we only need to set two of them equal to each other to solve for [tex]x[/tex]. Let's use [tex]AB[/tex] and [tex]BC[/tex] to solve for [tex]x[/tex]. We know that [tex]AB=BC[/tex], [tex]AB=2x+17[/tex], and [tex]BC=6x-19[/tex]. Therefore, we can write the following equation to solve for
[tex]AB=BC\\2x+17=6x-19[/tex] (Substitute given values into equation)
Solving for [tex]x[/tex], we get:
[tex]2x+17=6x-19\\2x+17-17=6x-19-17[/tex] (Subtract [tex]17[/tex] from both sides of the equation to isolate constants)
[tex]2x=6x-36[/tex] (Simplify)
[tex]2x-6x=6x-36-6x[/tex] (Subtract [tex]6x[/tex] from both sides of the equation to isolate [tex]x[/tex])
[tex]-4x=-36[/tex] (Simplify)
[tex]\frac{-4x}{-4}=\frac{-36}{-4}[/tex] (Divide both sides of the equation by [tex]-4[/tex] to get rid of [tex]x[/tex]'s coefficient)
[tex]x=9[/tex] (Simplify)
Therefore, [tex]AB=2x+17=2*9+17=18+17=35[/tex], and [tex]AB=BC=AC=35[/tex]. Hope this helps!
