Answer:So √0.9, would be ==> √9/10, which further will be equal to 3/√10.
Step-by-step explanation: Do the rationalisation part, and you will get your answer as 0.3(√10).
Answer:
1st piece = Piece A = 5 inches
2nd piece = Piece B = 10 inches
Third Piece = Piece C = 27 inches
Step-by-step explanation:
A 42-inch piece of steel is cut into 3 pieces
Let the lengths be represented as:
1st piece = Piece A
2nd piece = Piece B
Third Piece = Piece C
Hence:
A + B + C = 42
The 2nd piece is twice as long as the 1st piece
B = 2A
The 3rd piece is 2 inches more than 5 times the length of the first piece.
C = 5A + 2
Hence: we substitute
A + B + C = 42 inches
A + 2A + 5A + 2 = 42 inches
8A = 42 - 2
8A = 40 inches
A = 40 inches/8
A = 5 inches
Solving for B
B = 2A
B = 2 × 5 inches
B = 10 inches
Solving for C
C = 5A + 2
C = 5 × 5 + 2
C = 25 + 2
C = 27 inches
Therefore, the lengths of the 3 pieces =
1st piece = Piece A = 5 inches
2nd piece = Piece B = 10 inches
Third Piece = Piece C = 27 inches
Answer:
y = -(1/2)x + 2

Answer:
2+8, 3+5
Step-by-step explanation:
Answer: In 12 months they will have the same amount, which will be $520.
Step-by-step explanation:
220 + 25m = 100 + 35m
m = month
Subtract 100 from each side
120 + 25m = 35m
Subtract 25m from each side
120 = 10m
Divide each side by 10
12 = m
