If the Cylinder's height equals to the diameter of its base , then the fraction of the total surface area of the cylinder to the total surface area of the two bases is 1/3 .
The curved surface area of the cylinder with height "h" and radius "r" is written as ⇒ [tex]2\pi rh[/tex] ;
the area of the top and bottom of the cylinder is ⇒ [tex]\pi r^{2} + \pi r^{2}[/tex] = [tex]2\pi r^{2}[/tex] ;
the total surface area of the cylinder will be ⇒ [tex]2\pi rh[/tex] [tex]+2\pi r^{2}[/tex] ....equation(1)
it is given that the height of cylinder is equal to the diameter of the base ,
that means ; [tex]h = 2r[/tex]
Substituting the value [tex]h = 2r[/tex] in the equation(1) ,
we get ,
total surface area of cylinder = [tex]4\pi r^{2} +2\pi r^{2}[/tex] = [tex]6\pi r^{2}[/tex]
So , the required fraction is = [tex]\frac{2\pi r^{2} }{6\pi r^{2} }[/tex] ,
On simplifying ,
we get ,
= [tex]\frac{1}{3}[/tex] .
Therefore , the fraction of two bases to the total surface area is [tex]\frac{1}{3}[/tex] .

Solve the problem as directed. The force F of attraction between two bodies varies jointly as the weights of the two bodies and inversely as the square of the distance d between them. Express this fact as a variation using c as a constant. Use M1 and M2 for the weights of the two bodies.
Therefore, F = c * M1 * M2 / d^2 when the force F of attraction between two bodies varies jointly as the weights of the two bodies and inversely as the square of the distance between them using the C constant.
What is the distance?Distance is the sum of an object's movements, regardless of direction. Distance may be defined as the amount of space an item has covered, regardless of its beginning or finishing position.
What is direction?Direction is characterized as the course that anything follows, the route that must be taken to go to a certain location, the direction in which something is beginning to take shape or the direction you are facing.
F = c * M1 * M2 / d^2
Where,
F is the force of attraction,
M1 and M2 are the weights of the two bodies,

There are 10 marbles in a bag .2 red, 5 green and 3 blue. Aron picks up 2 marbles without
replacing the first marble. What is the probability that both the marbles are blue.
Answer:
It would be 0.09
Step-by-step explanation:
First, note the original Probability for picking a blue marble in the first try:
0.3
Now, if this were to happen again, knowing that no marbles would be taken out, it would be another chance of 0.3 for Aron to pick up a blue marble on his second pick up.
Due to these being independent events, you can do:
0.3*0.3 = 0.09
To get your answer, 0.09.
Answer:
27/90 = 3/10
Step-by-step explanation:
Calculate the probability that neither is blue
7/10 * 6 / 9
63/90
Now the remainder of the choices are what the probability is when both are blue
1 - 63 / 90
27/90 is the probability of choosing 2 blues.

You install 580 feet of fencing along the perimeter of a rectangular yard. The width of the yard is 144 feet. What is the length of the yard?
==========================================================
Explanation:
P = 580 is the perimeter of the rectangleW = 144 is the widthL = unknown lengthThe units for each are in feet.
The formula tying together all three variables is
P = 2(L+W)
which is the same as saying
P = 2L+2W
We can think of it having two copies of L and two copies of W, four sides total, added together to get the full perimeter.
I'll go with the first version. Plug in the given values and solve for L
P = 2(L+W)
2(L+W) = P
2(L+144) = 580
L+144 = 580/2
L+144 = 290
L = 290-144
L = 146 feet is the length
---------------
We can confirm this by saying
P = 2(L+W) = 2(146+144) = 2*290 = 580
Or we could say
P = 2L+2W = 2*146+2*144 = 292+288 = 580
or,
P = L+W+L+W = 146+144+146+144 = 580

Just re dot the points like mirror it on where ever on the graph
How do you plot a reflection on a point?Use the same x-coordinate and the y-opposite coordinate's to reflect a point on the x-axis. Use the same y-coordinate and the x-opposite coordinate's to reflect a point on the y-axis.
A point can be reflected in the x-axis, y-axis, or both axes.
Due to identical x-coordinates and opposing y-coordinates, the red spots on the x-axis are mirror reflections of one another. Thus, in opposing directions and 3 units away from the x-axis, are the red spots. A reflection in the x-axis is shown by the red spots.
Due to the identical y-coordinates and opposing x-coordinates, the blue spots on the y-axis are mirror reflections of one another. the blue points are thus

You are running a concession stand at a football game. You are selling snacks and sodas. Each order of nachos costs $2 and each soda costs $1.50. At the end of the night, you made a total of $125. You sold a total of 76 nachos and sodas combined. You must report the number of nachos sold and the number of sodas sold. What equations did you use to solve this
The equations are n + s = 76 and 2n + 1.50 s = 125.
let n = number of Nachos sold
let s = number of sodas sold
Two equations are presented to us, and we can use them together to solve one variable at a time.
Eq. 1: n + s = 76
Eq. 2: 2n + 1.50 s = 125
So, s = 76 - n
Put (76 - n) for s in the second equation
2n + 1.50 (76 - n) = 125
2n + 114 - 1.50 n = 125
2n - 1.50 n + 114 = 125
0.5n + 114 = 125
0.5n = 125 - 114
0.5n = 11
n = 22
s = 76 - 22
s = 54
22 nachos sold and 54 sodas sold.

What is word problem?A word problem is a few sentences that describe a "real-life" scenario in which a problem must be solved using a mathematical calculation.
Word problems are regarded as an important part of the primary curriculum because they require children to apply their knowledge of various concepts to'real-life' scenarios.
Let S = no. of skimmed pages
Let R = no. of read pages
Then S + R = 275
So R = 275 - S
Reading rate = 15 min/10 pages
Skimming rate = 10 min/15 pages
Total time to finish book = 350 min
So,
(R)(Reading rate) + (S)(Skimming rate) = 350 minutes
Substituting the values:
(275-S)(15/10) + (S)(10/15)=350
Multiplying equation through by 30 yields:
12375 - 45S + 20S = 10500
Combine terms
1875=25S
S = 75
