bogdanovich [222]

Answer:

0.05(2x +4) +0.25x =2.65

Step-by-step explanation:

The decimals are in the right places. A. would have been correct but it would have had to be 265 instead of 2.65. They put the decimals in the incorrect place.

10m^3 of air weigh 13 kg.
mihalych1998 [28]

Answer:

The weigh of air in the room having volume 38.22 m³ is 49.68 kg  

Step-by-step explanation:

Given as :

Length of room = 4.2 m

Width of room = 3.5 m

Height of room = 2.6 m

So ,  volume of room = Length × Width × Height

Or,   volume of room = 4.2 m × 3.5 m × 2.6 m

∴,     volume of room = 38.22 m³

Now,

∵  10 m³ of air weigh 13 kg

so, 1 m³ of air weigh =  \frac{13}{10} kg

∴    38.22 m³ of air weigh = \frac{13}{10} kg × 38.22 kg

I.e 38.22 m³ of air weigh = 49.68 kg

Hence The weigh of air in the room having volume 38.22 m³ is 49.68 kg  Answer
