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 cover an area of a square feet, when spacing the tiles a quarter inch apart. find t(400) and explain what it means.

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

For A=400 ft^2

substitute in the equation and solve for t

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

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
