How many 4ʹ × 8ʹ sheets of plywood are required to cover a floor that is 9 m by 16 m?

First, we find the area of the floor in square meters.

9 m * 16 m = 144 m^2

Now we convert the square meters to square feet.

144 m^2 * (1 ft)/(0.3048 m) * (1 ft)/(0.3048 ft) = 1550.0031 ft^2

Now we find the area of a 4' by 8' sheet of plywood in square feet.

4 ft * 8 ft = 32 ft^2

Now we divide the area of the floor by the area of a plywood sheet.

(1550.0031 ft^2)/(32 ft^2) = 48.44 sheets.

That means you need to buy 49 sheets.

step-by-step explanation:

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
