Find area of room
aera=legnth wtimes width
in a square, legnth=width
aera=legnth^2
legnth=14 feet
convert o inches
14*12=168 inches
area=168^2=28224 square inches
how many tiles will cover all of floor?
aka
how many 192 in^2 is at least 28224 (at least, because we need to cover the whole floor without gaps)
192x<u>></u>28224
divide both sides by 192
x<u>></u>147
147 is the number of tiles we need

Answer:
Marginal revenue equation is 0.1262x +1.3878 the production of the given number of bushels.
Step-by-step explanation:
Explanation:-
Given the revenue equation is R(x)=0.0631x^2 +1.3878x +2.1447
where 'x' is in hundreds of millions of bushels.
marginal revenue formula is calculated by dividing the change in quantity sold
Now differentiating R(x) with respective to 'x' , we get
<u>conclusion</u>:-
Marginal revenue equation is 0.1262x +1.3878 where 'x' the production of the given number of bushels.

Answer:
The price per pound of bananas is $0.5 and the price per pound of apples is $0.6
Step-by-step explanation:
Let
x -----> the price per pound of bananas
y -----> the price per pound of apples
we know that
12x+10y=12 -----> equation A
8x+5y=7 ----> equation B
Solve the system of equations by graphing
Remember that the solution is the intersection point both graphs
The intersection point is (0.5,0.6)
see the attached figure
therefore
The price per pound of bananas is $0.5
The price per pound of apples is $0.6
