Step 1
Find the area of one tile
we know that
the area of a square is

where b is the length side of the square
In this problem

Substitute

Step 2
Find the area of the floor
The area of a rectangle is equal to

where
L is the length of the rectangle
h is the width of the rectangle
In this problem


Substitute

Step 3
Find the number of tiles needed
by proportion

therefore
<u>the answer is</u>

Answer:
The slope should be 8 1/3 which is also 25/3
Step-by-step explanation:
Answer:
Step-by-step explanation:
let the smaller square be A, and the side is a
larger square is B, the side is a+3
Area(A)=a^2
Area(B)=(a+3)^2
a^2+(a+3)^2=425 in^2
a^2+a^2+6a+9=425
2a^2+6a=425-9
2(a^2+3a)=416 we divide by 2
a^2+3a=208
we solve the quadratic function
we will get two roots, a(1)=13, and the negative answer we will ignore
a=13 and the side of the larger square is 13+3=16
I believe it would be B. linear because it would depend on how much of a decrease the monthly rate changes and based on that the five hundred would change per every dollar (new customers=500x+5000) x being $decrease in monthly rate
