Answer:
9 inches ; 0.7 units ; m units
Step-by-step explanation:
The area of a square is give as :
The square of the side length of the square ; that is ;
Area of square = s² ;
Where s =! Side length of the square
Hence ;
A square with area = 81 in²
Length of its side = sqrt(81) = 9 inches
Area of square = 0.49 unit²
Length of its side = sqrt(0.49) = 0.7 units
Area of square = m² unit²
Length of its side = sqrt(m²) = m units
Answer:
30
Step-by-step explanation:
T+J = 140
J+W = 260
W= 5T
T+J = 140
5T+J = 260
T+J+120 = 5T+J
120=4T
T=30
J= 110
W=150
Solutions: x=3 , y=5 , z=2
x+y+z=10
2x-5y+2z=-15
4x+y-z=15
Find the unit rate, or cost of 1 gallon.
576/24=$24 per gallon
1664/64=$26 per gallon.
Paul's Paint sells paint for the least amount as 24<26.
