Answer:
666.95 $
Explanation:
If In a scale drawing of a dining room floor plan 10 mm = 2 meters
then 40 mm = (40 × 2) / 10 = 8 meters
and 32 mm = (32 × 2) / 10 = 6.4 meters
area of the dining room = 8 × 6.4 = 51.2 m²
1 square yard = 0.836 squared meters (m²) and it costs 10.89 $
Now we devise the following reasoning:
if 0.836 m² of flooring costs 10.89 $
then 51.2 m² of flooring costs X $
X = (51.2 × 10.89) / 0.836 = 666.95 $
The appropriate response is water. This reversible reaction can be broken into two responses. These two responses are happening all the while, which implies that the reactants are responding to yield the items, as the items are responding to deliver the reactants. Crashes of the responding atoms cause substance responses in a shut framework.
