First we need to convert the square feet to square inches

1 square feet = 144 square inches

Therefore, 81 square feet = 81*144 = 11,664 square inch

Each square tile is 18 inches long. Since its a square, the area of each tile = 18*18 = 324 square inch

So,the number of tiles required to cover the entire floor= total area of the floor in square inches/ area of the tile in square inches

The number of tiles required to cover the entire floor = 11,664/324 = 36 tiles

The number of tiles required to cover the entire floor = 36 tiles

Khaled bought 32 cups of juice to distribute to his students. He decided to drink 2 cups himself and pour each of his students 1
Temka [501]

Answer:

24 students

Step-by-step explanation:

So we started with 32 cups of juice.

Kahled drunk 2 cups so (32-2)=30 cups is left.

If x represents the number of students he receive juice and each student gets the same amount of juice which is 1.25 cups, then we have the equation

1.25x=30 to solve for x.

Divide both sides by 1.25:

x=30/1.25

x=24

24 students receive juice

with Judy jogging north and Jackie jogging west (on straight roads). When Jackie is 1 mile farther fro m the intersection than J
miskamm [114]
Let the distance of Judy from intersection is x and distance of Jackie from intersection is y.

We convert the given information to equations, step by step.

Point 1: When Jackie is 1 mile farther from the intersection than Judy.

This means y is 1 mile more than x.

So,

y = 1 + x

Point 2: The distance between them is 2 miles more than Judy’s distance from the intersection. 

Distance between is x+ y.

So, x+y is 2 miles more than y.

x+y = y + 2
⇒
x = 2

From point 1 we have:

y = 1 + x = 1+ 2 = 3

So,

Distance of Judy from intersection is 2 miles and distance of Jackie from intersection is 3 miles.

Paul is three times as old as Mary and Peter is four times as old as Mary,If the sum of their ages is 64, how old are Peter,Paul
uysha [10]
Let Mary's age be x.

Paul is three times as old as Mary, so Paul's age would be 3x.

Peter is four times as old as Mary, so Peter's age would be 4x.

The sum of their ages is 64
⇒ Paul's age+ Peter's age+ Mary's age= 64
⇒ 3x+ 4x+ x= 64
⇒ 8x= 64
⇒ x= 64/8
⇒ x= 8

Paul's age is: 3x= 3*8= 24

Peter's age is: 4x= 4*8= 32

Final answer: Paul is 24 years old.
Peter is 32 years old.
Mary is 8 years old.

Hope this helps~
