can someone please do this math problem with process shown
here ...
let us suppose breadth of the room be x.
then, length = 2x
now ,the cost of plastering the floor is RS 1080 at rate of RS 15 per ...
hence
the area of floor{length *breadth} =1080/15
x*2x=72
or,2x^2=72
or,x=√(72/2)
hence, the value of x= 6m
(ie. breadth {x}=6. &. length {2x}=12)
again....
we have ,
volume of the room (length *breadth*height)is 396m^3
12*6*height=396
72*height=396
height=396/72
hence , height=5.5
we know,
the area of 4 walls = 2( length+breadth)*height
=2(12+6)*5.5
=198
hence the cost of plastering 4 walls at the rate of RS 20 per SQ meter = 198*20=RS 3960

Q1: 250
Q2: 50
Step-by-step explanation:
Q1: 14,000 + 160x = 24,000 - 200x
24,000 - 14,000 = 10,000
200x - 160x = 40x
10,000/40x = 250
Q2: 800 - 6x = 1,000 - 10x
1,000 - 800 = 200
10x - 6x = 4x
200/4x = 50

Answer:
$97.524
Step-by-step explanation:
Write the slope-intercept form of the equation to the line parallel to the graph
of y+6=-4(x-1) that passes through the point (2,4).
Answer:
y = -4x + 12
Step-by-step explanation:
Parallel lines have the same slope. Since the slope of the given equation is -4, then the slope of the other line parallel to it must be the same.
Using the slope, m = -4, and the given point, (2, 4):
Substitute these values into the slope-intercept form:
y = mx + b
4 = -4(2) + b
4 = -8 + b
4 + 8 = -8 + 8 + b
12 = b
Therefore, the equation of the line parallel to y + 6 = -4(x - 1) is:
y = -4x + 12
Answer:
4x-2
Step-by-step explanation:
Slope intercept form is y=mx+b, so get y on one side.
do the multiplication first -4(x-1) is -4x+4
Now move the six to the other side; y=-4x+4-6
Simplify, y=-4x-2
The regular price of a t-shirt is 18 dollars. What price will you pay after a 20% discount
Answer: $14.40
Step-by-step explanation:
Full price = $18.00
20% discount of full price = $18.00 x [tex]\frac{20}{100}[/tex]
= $18.00 x 0.2
= $3.60
Price paid after 20% discount = full price minus 20% discount
= $18.00 - $3.60
= $14.40
Points A,B,C and D are collinear points such that the order is A-B-C-D and AB>CD which of the following statement is true (A) BCBC (C) ABBD
Answer:
The answer is differently C
Write the equation of the graph in slope-intercept form (y=mx+b).
Write the equation without spaces:
Answer:
y = mx + b is the slope intercept form of writing the equation of a straight line. In the equation 'y = mx + b', 'b' is the point, where the line intersects the 'y axis' and 'm' denotes the slope of the line. The slope or gradient of a line describes how steep a line is. It can have either a positive or a negative value. When a standard form of a linear equation is of the form Ax + By = C, where 'x' and 'y' and 'C' are variables and 'A', 'B' are constants, the slope-intercept form is the most preferred way of expressing a straight line due to its simplicity, as it is very easy to find the slope and the 'y intercept' from the given equation.
Meaning of y = mx + b
y = mx + b is the slope-intercept form of a staight line. In the equation y = mx + b for a straight line, m is called the slope of the line and b is the y-intercept of a line. y = mx+b, where
y ⇒ how far up or down is the line,
x ⇒ how far along is the line,
b ⇒ the value of y when x = 0 and
m ⇒ how steep the line is.
This is determined by m = (difference in y coordinates)/ (difference in x coordinates). Note that difference in y coordinates is indicated as rise or fall and difference in x coordinates is indicated as run.

Challenge A movie theater sends out a coupon for 15% off the price of a ticket. Write an equation
for the situation, where y is the price of the ticket with the coupon, and x is the original price of the
ticket. Use pencil and paper. Draw a graph of the equation and explain why the line should only be
in the first quadrant
Answer:
The equation is y= 0,65 x
If x is the price of the ticket without the coupon, and the theater offers a discount if you have a coupon, then having a coupon means that the price a person ultimately pays (y) is the original price (x) minus a 35% of this price: y= x -0.35 x . By association: y= (1-0.35) x and then y= 0.65 x.
The line should be in the first quadrant because the first quadrant allows you to represent a situation in which the dependent variable (y) and the independent variable (x) are both positive. This is the case in this exercise, because both prices, the one without discount (x) and the one with discount (y) are necessary positive (you can not pay a negative price!).
Step-by-step explanation:
The price without discount (or without the coupon) is x.
The price with discount (or with coupon) is y.
y and x are both related: y is a percentage of x, specifically, y is 35% smaller than x. This means that y =0.65 x.
Answer:
0.85x

Step-by-step explanation:
The sum of an infinite geometric series is expressed according to the formula;
a 1 r where;
a is the first term of the series
r is the common ratio
If the sum of an infinite geometric series is three times the first term, this is expressed as
S∞ = 3a
Substitute S = 3a into the formula above to get the common ratio r;
a
3a 1-r
cross multiply
3a(1-r) = a
3(1-r) = 1
open the parenthesis
3- 3r 1
subtract 3 from both sides
33r31-3
-3r = -2
2|3 r =
Hence the common ratio of this series is 2 upon 3
= 2\3

c=4a+4b solve for b
Answer:
[tex]b = -a +\frac{1}{4}c[/tex]
Step-by-step explanation:
Step 1: Flip the equation.
[tex]4a + 4b = c[/tex]Step 2: Subtract 4a from both sides.
[tex]4a + 4b - 4a = c - 4a[/tex] [tex]4b = c - 4a[/tex] [tex]4b = -4a + c[/tex]Step 3: Divide both sides by 4.
[tex]\frac{4b}{4}=\frac{-4a}{4} + \frac{c}{4}[/tex] [tex]b = -a + \frac{1}{4}c[/tex]Therefore, the answer is [tex]b = -a + \frac{1}{4}c[/tex].
Hope you have a lovely rest of your day/night.
Answer:
b = [tex]\frac{c - 4a}{4}[/tex]
Step-by-step explanation:
c = 4a + 4b
Subtract 4a from both sides:
c - 4a = 4a - 4a + 4b
c - 4a = 4b
Divide both sides by 4 to solve for b:
[tex]\frac{c - 4a}{4} = \frac{4b}{4}[/tex]
b = [tex]\frac{c - 4a}{4}[/tex]

Which statement best describes how ultrasound can produce an image?
A. Sound waves emitted by the machine bounce off tissues and
return to the machine.
B. Sound waves that form outside the body reflect off the body and
are detected by the machine.
C. Sound waves that form within the body travel to the machine,
where they are detected.
D. Sound waves emitted by the machine pass through the body and
are measured on the other side.
Answer:
A
Step-by-step explanation:
just did it :)
The statement that best describes how ultrasound can produce an image is sound waves that form outside the body reflect off the body and are detected by the machine.
What is Ultrasound?Diagnostic ultrasound, also called sonography or diagnostic medical sonography, is an imaging method that uses sound waves to produce images of structures within your body.
We have some statements that describes how ultrasound can produce an image.
The ultrasound image is produced based on the reflection of the waves off of the body structures. The strength (amplitude) of the sound signal and the time it takes for the wave to travel through the body to provide the information necessary to produce an image.
Therefore, the statement that best describes how ultrasound can produce an image is sound waves that form outside the body reflect off the body and are detected by the machine.
