the lenght of a room is twice its breadth and thrice its height if the cost of carpeting the floor at rs 80 per sq metre is rs 9000 find the cost of plastering its walls and ceiling at rs 35 per sq metre
Answer:
Let's define the variables:
L = length of the room
B = breadth of the room
H = height of the room.
We know that:
L = 2*B
L = 3*H
Remember that the area of a rectangle of length L and breadth B is:
A = L*B
Then the area of the floor of the room is:
A = L*B
and L = 2*B, if we replace that, we get:
A = (2*B)*B
A = 2*B^2
Now, we know that the cost of carpeting the floor is $80 per m^2
And the total cost was $9000
Then the number of square meters in the floor (thus, the area of the floor) is:
A = ($9000)/($80) m^2
A = 112.5 m^2
With this, we can find the value of B.
A = 112.5 m^2 = 2*B^2
B = √( 112.5/2) m = 7.5 m
Then the length is:
L = 2*B = 2*7.5m = 15m
And the height is:
L = 3*H
H = L/3 = 15m/3 = 5m
Now that we know all the dimensions of the room, we need to find the area of the four walls, and the area of the ceiling (which is equal to the area of the floor 112.5 m^2)
Now, we will have two walls with an area of:
area = breadth*height = B*H = (7.5m)*(5m) = 37.5m^2
And two walls with an area of:
area = length*height = L*H = 75m^2
Then the total area of the four walls plus the ceiling is:
A' = 2*(37.5m^2) + 2*( 75m^2) + 112.5 m^2
A' = 337.5 m^2
And we know that for each m^2, the cost of plastering is $35
Then for 337.5 m^2, the cost will be 337.5 times $35
Cost = (337.5)*$35 = $11,812.50
What are the x- and y- intercepts of the graph of 9x-3y = 18?
Step-by-step explanation:
9x - 3y = 18
Solve for y:
1. 3y= 9x + 18
2. y= 3x + 6 (This is the equation you will graph)
To graph:
Make a table for y = 3x +6.
If x =0, y=6
If x =1, y=9
If x =-1, y=3

What is the distance from 33, 5) to (3 7.-1
Answer:
7.211
Step-by-step explanation:
I'm going to assume that's supposed to say (33, 5) to (37, -1)
Use the pythagorean theorem: a^2 + b^2 = c^2
"a" is going to be your difference in x values (37 - 33) = 4
"b" is going to be your difference in y values (5 - (-1)) = 6
4^2 + 6^2 = c^2
16 + 36 = c^2
52 = c^2
sqrt(52) = c
7.211 = c

Write the equation in slope-intercept form. -10x+2y=12
-please help
Answer:
y=5x+6
hope this helps
have a good day :)
Step-by-step explanation:
The slope intercept form for the equation -10x+2y=12 is y= 6+5x
What is slope- intercept form?The slope intercept form is a method used to determine the equation of a straight line in the coordinate plane. The equation of a straight line will be that relation which:
the coordinates of any point on the line must satisfy.the coordinates of any point not on the line will not satisfy.The determination of this equation is straightforward. To find the slope intercept form of a straight line, we would need the slope, or the angle of inclination of this straight line from the x-axis and the intercept that it makes with the y-axis.
Given:
-10x+2y=12
As, we know the slope- intercept form is
y= mx +b
Then writing the equation as the slope intercept form
-10x+2y=12
2y = 12 +10x
Divide both side by 2 to make the coefficient as 1.
y= 12/2 + 10x/2
y= 6 + 5x
Hence, the slope intercept form is y= 6+5x

Consider the following discrete time process: at integer times, a marble arrives which can be one of m colors. Each color is equally likely; all events at different times are independent. As each marble arrives, it is placed into a bowl Unless there is a marble of that color already in the bowl. Then, that marble is removed from the bowl and the new marble does not go into the bowl. (The pair is placed in a separate bin for shipping). Let Gn denote the number of marbles currently in the bowl after the nth marble arrives. Compute,(a) the expectation E(Gn).(b) limn→[infinity] E(Gn).
Answer:
Below are the responses to the given question:
Step-by-step explanation:
Let X become the random marble variable & g have been any function.
Now.
For point a:
When X is discreet, the g(X) expectation is defined as follows
Then there will be a change of position.
E[g(X)] = X x∈X g(x)f(x)
If f is X and X's mass likelihood function support X.
For point b:
When X is continuing the g(X) expectations is calculated as, E[g(X)] = Z ∞ −∞ g(x)f(x) dx, where f is the X transportation distances of probability.If E(X) = −∞ or E(X) = ∞ (i.e., E(|X|) = ∞), they say it has nothing to expect from EX is occasionally written to stress that a specific probability distribution X is expected.Its expectation is given in the form of,E[g(X)] = Z x −∞ g(x) dF(x). , sometimes for the continuous random vary (x). Here F(x) is X's distributed feature. The anticipation operator bears the lineage of comprehensive & integral features. The superposition principle shows in detail how expectation maintains equality and is a skill.

Find the number of distinguishable permutations of the letters PEPPERONI. NO LINKS!!!!
This is is one value (and not two values separated by a comma) and it's slightly over 30 thousand.
========================================================
Explanation:
There are n = 9 letters in the word "PEPPERONI"
If we could tell all the letters apart, there would be 9! = 9*8*7*6*5*4*3*2*1 = 362,880 permutations, and that would be the answer.
However, we have repeated letters that we cannot tell apart. The P shows up a = 3 times, and the E shows up b = 2 times. So we need to divide by a!*b! = 3!*2! = 6*2 = 12 to correct for the overcounting. That leads to the final answer of (362,880)/(12) = 30,240

Answer:
B) 171 units^2
Step-by-step explanation:
The area is given by the formula ...
A = 1/2(b1 +b2)h
Filling in the given base and height values, we find the area to be ...
A = 1/2(23 +15)(9) = (19)(9) = 171 . . . square units
_____
Additional comment
You can select the correct answer choice simply on the basis of "reasonableness." If this were a 9×15 rectangle, its area would be 9×15 = 135 square units, more than 85.5. You know its area is less than a 9×23 rectangle, so is less than 9×23 = 207 square units. Only one answer choice is a value between 135 and 207.

Multiplication by 9 is not so hard. It is multiplication by 10-1:
15×9 = 15×(10 -1) = 150 -15 = 135
