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
Answer:
160
Step-by-step explanation:
With the problem, it's best to put this into a fraction
8/20 of every student will be absent from school less than five days a year, which can then be simplified to 2/5.
There are multiple ways to go about this problem, but my preferred way is to then take 1/5th of 400, which can be done by taking 1*400/5 which equals 80. Since we are asking for 2/5's, just multiply that number by 2, which gives us 160 students.
