If 6.5x meters of rope is needed, Bill needs x meters of rope, Amy needs 0.5x meters of rope and Carmen needs 5x meters of rope.
Step-by-step explanation:
Step 1:
Assume Bill needs x meters of rope, Amy needs y meters of rope, and Carmen needs z meters of rope.
Amy needs a piece half as long as Bill's and Carmen needs 5 times as much rope as Bill.
So we have and
Step 2:
So the total rope needed
So if x = 1, x = 1 meter, y = 0.5 meters, z = 5 meters, a total of 6.5 meters of rope.
So if x = 2, x = 2 meter, y = 1 meters, z = 10 meters, a total of 13 meters of rope.
Answer:
$13500
Step-by-step explanation:
Given
Each tile cover one ninth of a square yard and each tile costs $3
First, area of the Swimming Pool(from the diagram)
=Area of Left rectangle(length=20,breadth=10)+ Area of Square in middle(side=10)+Area of right rectangle(length=20,breadth=10)
We have to calculate how many tiles make up 500 yards
As given each tile is one ninth of a yard
⇒Number of tiles that make up 500 yards, n
⇒ As each tile costs $3
Therefore total cost to tile the floor
Therefore total cost of tiles=$13500
