Given:
The conversions from meter to inches and inches to meter are shown in part A of model 2.
The conversions from liters to quarts and quarts to liters are shown in part B of model 2.
Required:
To find the relationship between the conversion factors used in Part A of Model 2.
To find the relationship in the the conversion factors used in Part B of Model 2.
Explanation:
We have given that 1 meter = 39.4 inches.
Thus, from the calculations shown in part A of model 2, we can conclude that the quantity from meters to inches is converted as:
Thus, 1.5 m =59 inches.
Also, the quantity from inches to meters is converted as:
Hence, 59 in = 1.5 m.
Next,
We have 1 L = 1.06 qt.
Thus, from the calculations shown in part B of model 2, we can conclude that the quantity from quarts to liters is converted as:
Thus, 186 quarts = 175 L.
Also, the quantity from liters to quarts is converted as:
Hence, 175 L = 186 qt.
Final Answer:
We conclude that:
While converting from meters to inches, we multiply the quantity 1.5 by the equality quantity given.
While converting from incehs to meters, we divide the quantity 59 by the equality quantity given.
Also, While converting from quarts to liters, we divide the quntity 186 by the equality quantity given.
While converting from liters to quarts, we multiply the quntity 175 by the equality quantity given.
Answer:
The expression is equal to
The area of the scale drawing is
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
let
z------> the scale factor
x------> the area of the actual room
y-----> the area of the scale drawing
so
we have
substitute and solve for y
