Find the cost of carpeting a room 3.6m high at Rs 120 per square meter if it contains 240 mcube of air
NeX [460]

Answer:

Rs 8000

Step-by-step explanation:

Volume = Base area × Height

If we want to find the cost of carpeting a room, we need to find how much space there is to carpet, which would be the base area of the room.

240m³ = Base area × 3.6m

Base area = 240m³ ÷ 3.6m

Base area = 66\frac{2}{3}m²

1m² --- Rs 120

66\frac{2}{3}m² --- 66\frac{2}{3} × Rs 120 = Rs 8000

I need help on this pls help
levacccp [35]

Answer:

slope = -\frac{3}{4}

Step-by-step explanation:

The slope of a line can be found by identifying two points and the graph and finding the overall change in y over the change in x:

slope=\frac{(y_{2}-y_{1})  }{(x_{2}-x_{1})  }

Using the points on the given graph of (-3, 2) and (1, -2):

\frac{-1 - 2}{1 - (-3)}=\frac{-3}{4}

So, slope = -\frac{3}{4}
