Given :
Rosa is putting carpet in her room. She’s using the scale 1 inch = 3 ft .
In the drawing, the length is 5.5 inches and the width is 3.25 inches. If carpet costs 2.58 per square foot.
To Find :
How much will it cost to carpet the bedroom.
Solution :
Length of bedroom , l = 5.5 × 3 = 16.5 ft.
Width of bedroom , w = 3.25 × 3 = 9.75 ft.
SO, area of bed room is :
[tex]A=l\times w\\\\A=16.5\times 9.75\ ft^2\\\\A=160.875\ ft^2[/tex]
Now, cost to carpet the bedroom is :
[tex]C=2.58\times A\\\\C=2.58\times 160.875\\\\C=415.0575[/tex]
Hence, this is the required solution.

Answers
Answer:
The expense of 7 men for 13 days is 18,200 Rs.
Step-by-step explanation:
The expense of 14 men for 8 days = 22400
The expense of 14 men per day = 22400/8 = 2800
The expense of 1 man per day = 2800/14 = 200
The expense of 7 men per day = 200*7 = 1400
The expense of 7 men for 13 days = 1400*13 = 18200

S1. Three numbers are in the ratio of 2:3:4. The sum of their cubes is 3,34,125. Find the numbers.
Answers
Answer:
Step-by-step explanation:
sum of their cubes=0.334125
The ratio of three numbers is 2:3:4.
Let the numbers be 2x, 3x and 4x.
Cubes of numbers = (2x)^3, (3x)^3, (4x)^3 = 8x^3, 27x^3, 64x^3
(8x^3) + (27x^3) + (64x^3) = 99x^3
99x^3 = 0.334125
x^3 = (0.334125) / 99
x^3 = 0.003375
x^3 = (0.15)^3
x = 0.15
Therefore, the numbers are (2 x 0.15), (3 x 0.15) and (4 x 0.15) i.e. 0.3, 0.45 and 0.6

Answers
Is the answer
Answer:
38.9 degrees C
Step-by-step explanation:
Use the equation:
[tex]C=\frac{5}{9} (F-32)[/tex]
to convert degrees Fahrenheit to degrees Celsius. So replace the value for the Fahrenheit with 102 and solve for C:
[tex]C=\frac{5}{9} (F-32)\\C=\frac{5}{9} (102-32)\\C=\frac{5}{9} (70)\\C=\frac{350}{9} \approx38.89\,^oC[/tex]
which to the nearest tenth can be written as: 38.9 degrees C

if (x,y) is the solution to the system of equations above, what is the value of 3x - y?
Answers
3x - y = 5
Step-by-step explanation:2x + y = 10 | ×2
x - 2y = -5
4x + 2y = 20
x - 2y = -5
add
4x + x + 2y - 2y = 20 - 5
5x = 15
x = 15 : 5
x = 3
replace x
4(3) + 2y = 20
12 + 2y = 20
2y = 8
y = 8 : 2
y = 4

Dwayne buys 1 loaf of bread and 6 eggs for $4.45. Sheila buys 1 loaf of bread and 1 dozen eggs for $5.65. Let x be the cost, in dollars, of a loaf of bread. Let y be the cost, in dollars, of an egg.
Answers
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Let x = cost of a loaf of bread ; y = cost of an egg
Dwayne :
1 loaf of bread and 6 eggs :
X + 6y = 4.45 - - - (1)
Sheila :
X + 12y = 5.65 - - - (2)
From (1);
X = 4.45 - 6y
In (2):
(4.45 - 6y) + 12y = 5.65
4.45 + 6y = 5.65
6y = 5.65 - 4.45
6y = 1.2
y = 0.2
From X = 4.45 - 6y:
X = 4.45 - 6(0.2)
X = 4.45 - 1.2
X = 3.25
Cost of a loaf of bread = $3.25
Coat of an egg = $0.2
