Answer:
There are 271.74 ft^2 not covered by the rug
The percentage not covered by the rug is 90.58%
Step-by-step explanation:
step 1
Find out the area of the room
The area of the rectangular room is
step 2
Find out the area of the circular rug
The area of the circle is
we have
----> the radius is half the diameter
substitute
step 3
Find out what percentage of the room is not covered by the rug
we know that
300 ft^2 represent the 100%
so
using proportion
Find out what percentage represent the difference (300-28.26)=271.74 ft^2
Let
x ----> the percentage not covered by the rug
Convert to fraction form
Simplify
therefore
There are 271.74 ft^2 not covered by the rug
The percentage not covered by the rug is 90.58%
Answer:
a.Elimination method
b.substitution method
c.substitution method.
Step-by-step explanation:
the reason I'm going to use elimination for the first one a. its because we were given two equations with coefficients and to solve for them, we need to eliminate one of the variables and solve for the other then use the answer for the non eliminated variable to solve for the eliminated variable and its quite easy to do so.
for b and c. I choose to use substitution method to answer the equations because the y equation was given to us. The easiest thing to do is just to substitute Y equation in the given equation and solve for your variables.
