Don works in home construction. He determined that the function t(A)=144A/9.252 gives the total number of 9 in. tiles needed to
Oksanka [162]

Answer:

6,226 tiles of 9 in are needed to cover an area of 400 square feet

Step-by-step explanation:

Let

A -----> an area in square feet

t(A) ---> the total number of 9 in. tiles needed

we have

t(A)=\frac{144A}{9.252}

For A=400 ft^2

substitute in the equation and solve for t

t(400)=\frac{144(400)}{9.252}

t(400)=6,226\ tiles

That means -----> 6,226 tiles of 9 in are needed to cover an area of 400 square feet

How do you find average speed with hours and minutes?

How to calculate average speed. Speed is distance divided by time. Simply put, if you drove 60 kilometer's for one hour, it would look like this: Speed = distance (60 km) / time (1 hour) = 60km/h.
