Answer:
For this question, we use the formula for the volume of a cylinder.
(formula for vol. of cylinder)
V = π[tex]r^{2}[/tex]h
Where 'π' represents pi(22/7 or 3.14), 'r' represents the radius which is being squared, and 'h' stands for the height.
We utilize the information that we know:
Radius = 6cmVolume = 904.78Which we then plug into our equation(volume of cylinder formula):
V = π[tex]r^{2}[/tex]h
904.78 = 3.14(6^2) · h
Next solve for the h(height).
904.78 = 3.14(36) · h
904.78 = 113.04 · h
904.78 = 113.04h
/113.04 /113.04
8.00406935598 = h, which we round to 8.
8 centimetres is the height of this cylinder.

This is the correct solution:
27r^2 - 48 Divide through by 3:
= 3(9r^2 - 16) 9r^2- 16 is the difference of 2 squares so:

Which is an equation of the line that passes through
the points (5, 2) and (10, -3)?
Answer:
y = -x + 7
Step-by-step explanation:
Hi there!
We are given the following points:
(5,2) and (10,-3)
We want to find the equation of the line that passes through these 2 points
There are 3 ways to write the equation of the line, yet the most common way is slope-intercept form, which is y=mx+b (m is the slope and b is the y intercept).
First, let's find the slope of the line.
The slope can be calculated from 2 points using the equation [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points
We have everything we need to find the slope, but let's label the values of the points to avoid confusion and mistakes.
[tex]x_1=5\\y_1=2\\x_2=10\\y_2=-3[/tex]
Now substitute these values into the formula to find the slope
m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
m=[tex]\frac{-3-2}{10-5}[/tex]
Simplify
m=[tex]\frac{-5}{5}[/tex]
Divide
m=-1
The slope of the line is -1
We can substitute this value as m in y=mx+b.
Here's the equation of our line so far:
y=-x+b
Now we need to find b
As the equation passes through the points (5,2) and (10,-3), we can use either point to find the value of b
Taking (5,2) for example:
Substitute 5 as x and 2 as y
2=-5+b
Add 5 to both sides
7=b
Substitute 7 as b in the equation
y = -x + 7
Hope this helps!

Let's solve ~
Cost price for each Orange :
[tex]\qquad \tt \dashrightarrow \: \dfrac{60}{200} [/tex]

Help I know that I have to move 3x to 4x with will be -3x and then I will subtract it then I will be left with -x and then I'll be with -x -3 what do I do after ?
4x -3 = 3x
Answer:
[tex]\sf \boxed{\bold{x = 3}}[/tex]
Explanation:
4x -3 = 3xsubtract both sides by 4x
4x - 3 -4x = 3x - 4xgroup similar terms
4x - 4x - 3 = -xsimplify
-3 = -xdivide both sides by -1 or cancel out the negatives
x = 3Check:
4(3) -3 = 3(3)12 - 3 = 99 = 9L.H.S = R.H.S Thus x = 3 confirmed
Answer:
x = 3
Step-by-step explanation:
We are trying to move all terms that have x on one side of the equal sign and terms that do not have an x on the other side of equal sign.
terms with x = terms without x
4x -3 = 3x , subtract 3x from both side of the equation
4x -3x -3 = 3x -3x
4x -3x -3 = 0 , add 3 to both sides of the equation
4x -3x -3 + 3 = 0 + 3
4x -3x = 3 , combine like terms
x = 3
Or
We can think we move each term where we want it, yet keep in mind that once we cross the equal sign we change the sign of the term if addition or subtraction are the only operations involved.
4x -3 = 3x , 3x is positive so will become negative on the other side of the equal sign and -3 is negative so will become positive on the other side.
4x -3x = 3
x = 3

The seattle great wheel is an illustration of sectors, arcs, circumference and area of circles
The circumference of the wheelThe diameter is given as:
d = 175 feet
The circumference (C) is calculated as:
C = πd
This gives
C = 3.14 * 175
C = 549.5 feet
Hence, the circumference of the wheel is 549.5 feet
The area of the wheelThis is calculated as:
A = π(d/2)^2
This gives
A = 3.14 * (175/2)^2
A = 24040.625
Hence, the area of the wheel is 24040.625 square feet
The central angle (degrees)This is calculated as:
θ = 360/n
Where n is the number of capsules
So, we have:
θ = 360/42
This gives
θ = 8.57 degrees
Hence, the central angle of the wheel in degrees is 8.57
The central angle (radians)This is calculated as:
Radians = Degrees × π/180
So, we have:
θ = 360/42 * π/180
This gives
θ = π/21 rad
Hence, the central angle of the wheel in radians is π/21 rad
Arc length between two capsulesThis is calculated as:
L = θ * d/2
So, we have:
L = π/21 * 175/2
This gives
L = 175π/42
Hence, the arc length between two capsules is 175π/42
Area of sector between two capsulesThis is calculated as:
A = 0.5 * (d/2)^2 * θ
So, we have:
A = 0.5 * (175/2)^2 * π/21
This gives
A = 168π
Hence, the area of sector between two capsules is 168π

Answer:
70
Step-by-step explanation:
Same side interior angles of parallel lines cut by a transversal are supplementary, so their measures have a sum of 180°.
2x - 5 + 45 = 180
2x + 40 = 180
2x = 140

Answer: x = 56
Step-by-step explanation:
The two angles 'z' and 124 add up to form a straight line. The angle of a straight line is 180 degrees. Therefore, we can say that:
[tex]z+124=180[/tex]
Subtract 124 on both sides to isolate the angle 'z' to get:
[tex]z=56[/tex]
Answer:
z=56 degrees
Step-by-step explanation:
in total the line will equal 180 so just do 180-124 and you get 56.

for the second pair of angles, the angle of reference is really about 26.57°. Now, the tangent is only negative in two quadrants, the II and IV Quadrants, using the angle of reference, it'd give us those angles.
