Given that a square patio of at least 80 square feet is to be built from 125 tiles of length 12 inches or 1 feet.
Part A;
Since there are 125 tiles and the patio has a shape of a square of at least 80 square feet, then the possible dimensions of the patio are
9 ft by 9 ft = 81 ft
10 ft by 10 ft = 100 ft, and
11 ft by 11 ft = 121 ft.
Part B.
For a patio of dimensions, 9ft by 9ft, the number of tiles that will not be used is given by 125 - 81 = 44
For a patio of dimensions, 10ft by 10ft, the number of tiles that will not be used is given by 125 - 100 = 25
For a patio of dimensions, 11ft by 11ft, the number of tiles that will not be used is given by 125 - 121 = 4
Answer:
The equation of line with given points is Y = - 
X + 1
Step-by-step explanation:
Given as :
The points are ( 16 , - 5 ) And ( -40 , 16 )
The line equation in points form :
Y - y1 = m ( X - x1)
Where m is the slope of line
Now , m = 
Or, m = 
Or, m = 
SO, Y + 5 = m ( X - 16)
Put the value of slope
∴ Y + 5 = 
( X - 16)
Or, ( - 56) × ( Y + 5 ) = 21 X - ( 21 × 16 )
Or, - 56 Y - 280 = 21 X - 336
Or, - 280 + 336 = 21 X + 56 Y
Or, 56 = 21 X + 56 Y
∴ Y = - 
X + 1
Or, Y = - X + 1
Hence The equation of line with given points is Y = - X + 1 Answer
Answer:
$64.00
Step-by-step explanation:
Company A:
C = 3.25x
3.25 x 80 = 260
Company B:
C = 2.45x
2.45 x 80 = 196
How much more?
260 - 196 = 64
Group first 2 and group last 2 and find factors and undistribute
(4x^3+x^2)+(-8x-2)
(x^2)(4x+1)+(-2)(4x+1)
x^2(4x+1)-2(4x+1)
answer is first one
