An architect makes a scale drawing of a house. in real life, the width of the porch is 7 meters. on the drawing, the width is 4 cm. what scale was used for the drawing? a) 1 cm = 1.25 m b) 1 cm = 1.75 m c) 1 cm = 1 4 m d) 1 2 cm = 1 m

Scale used for drawing is 1 cm = 1.75 m

Step-by-step explanation:

An architect makes a scale drawing of a house.

Actual width of porch  = 7 meters

Width of porch on drawing = 4 cm

So, Actual width = Drawing width

So, 4 cm = 7 m

1 cm = 1.75 m

So, Scale: 1 cm = 1.75 m

So, Option B is correct

B)1 cm = 1.75 m

Hence scale used for drawing is 1 cm = 1.75 m

step-by-step explanation:

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
