Question:

DanielleElmas [232]

Given A room is half as long again as it is broad

Let the breadth of the room x m

length of the room x + x/2 = 3x/2m

Area of the room , x × 3x/2 = 3x²/2m

Given , cost of carpeting the room at Rs. 3.25m⁻²

So , total cost , 3x²/2 × 3.25

But , Total cost of carpeting is given as 175.50 so ,

(3x²/2 )× 3.25 = 175.50
x² = 175.50 × 2 / 3.25 × 3
x² = 36
x = 6

Breadth x = 6 m
length 3x/2 = 9m

let the height of the room H m

Area of the four wall = 2(L+ b)× h 2(6+9)× H

= 30H m²

Area of the of the one door and two window is 8m²

8m² Area to be prepared = Area of four wall - area of two window and 1 door = (30H - 8) m²

Given cost of preparing wall is Rs. 1.40m²

total cost of preparing wall is (30H - 8) × 1.40

Total cost of preparing wall is given as 240.80

comparing , (30H - 8 ) × 1.40 = 240.80

(30H - 8 ) = 240.80 /1.40 = 172
30H -. 8 = 172
30H = 180
H = 180/30 = 6

Hence, Dimensions of the room are lengths 9m , breadth 6m and height 6m

A bag contains two red balls and five blue balls. You draw out a ball, record its color, replace it, and then draw out a second

GREYUIT [131]

Hello there, and thank you for asking your question here on brainly.

Short answer: B. 0.71

Why?

To find probability, you have to divide both the total number of possibilities, (7) and divide that by the greatest number of possibilities. (5). 5/7 ≈ 0.71

Hope this helped you! ♥

Solve for X, (with steps please) 0.46=0.527-[0.0562/2 * log(0.1+x/1.5-x)]

Ivanshal [37]

Rearrange the equation:

$\frac{0.0562}{2} * log( \frac{0.1+x}{1.5 - x}) = 0.527 - 0.46 = 0.067$

Isolate the log on its own

$log (\frac{0.1 + x}{1.5 - x}) = \frac{0.067*2}{0.0562} = 2.42 (2dp)$

To get rid of the log you must do 10^2.42

$\frac{0.1 +x}{1.5-x} = 10^{2.42} = 242.29 (2dp)$

Then multiply both sides by (1.5 - x)

$0.1 +x = 242.29(1.5-x)$

$0.1 + x = 363.44 - 242.29x$

Solve normally

$243.29x = 363.34 x = 363.34/243.29 x= 1.49344 x= 1.49 (2dp)$

Hope that helps. Please send me a message if there's patchy bits. Also I'm sure you'll figure this out, but just in case, anywhere I've put down a 2dp shows that I've rounded the number to 2 decimal places. It becomes a pain to deal with otherwise.
