Answer:
The air weight in a room is 49.69 kg.
Step-by-step explanation:
It is given that the room is 4.2m long, 3.5m wide, and 2.6m high. It is also given that 10 m³ of air weigh 13 kg.
The formula to find the volume of cuboid is,
The volume of room is 38.22 m³.
Since it is given that, 10 m³ of air weigh 13 kg. So,
So the air weight in the room is,
Therefore the air weight in a room is 49.69 kg.
Answer:
6x + 48
Step-by-step explanation:
multiply each term inside the () by 6
6x + 6*8
Step-by-step explanation:
The ratio of the perimeters = the scale
P₂ / P₁ = 6 / 4 = 3 / 2
The ratio of the areas = the square of the scale
A₂ / A₁ = (6 / 4)² = (3 / 2)² = 9 / 4
Same for the triangles:
P₂ / P₁ = 6 / 3 = 2
A₂ / A₁ = (6 / 3)² = (2)² = 4
Wild guess?

Answer:
x=1/3
Step-by-step explanation:
first multiply both bracket to together and then you get, 9x=3
x=1/3, then sub in to other equation and get the rest answer.
