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

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
