On a scale drawing 1/4 inch=1 foot. what are the dimensions on a scale drawing of a room that is 20ft by 27ft

5 inches by inches

Step-by-step explanation:

According to the scale given, to convert "feet" to "inches", we have to multiply each feet by 1/4th. The drawing would be a "smaller" version of the original. That would be in inches.

So, 20 ft would be:

20 * 1/4 = 20/4 = 5 inches

and

27 feet would be:

27 * 1/4 = 27/4 inches

The dimension would thus be:

5 inches by inches

it happens during combustion and impacts the environment because the plants and trees take in that and it can cause them to die.

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m
