Answer:

$t(400)=673$ .

It means that 673 of 9 inch tiles are required to cover an area of 400 square feet, when spacing the tiles a quarter inch apart.

Step-by-step explanation:

Given:

The function relating number of 9 inch tiles required and area to cover is:

$t(A)=\frac{144}{9.25^2}A$

Now, plug in 400 for $A$ to evaluate $t(400)$ .

$t(400)=\frac{144}{9.25^2}\times 400=\frac{144\times 400}{85.5625}=\frac{57600}{85.5625}=673.19\approx6225$

Therefore, Don required 673 of 9 inch tiles to cover an area of 400 square feet, when spacing the tiles a quarter inch apart.

Answer:

$n^{3} + 15n^{2} + 56n$

Step-by-step explanation:

First FOIL (n + 7)(n + 8) and then distribute n

(n + 7)(n + 8) = $n^{2} +15n + 56$

n ( $n^{2} +15n + 56$ )

= $n^{3} + 15n^{2} + 56n$

Answer:

469.42 ft²

Step-by-step explanation:

Law of sines;

w/sin27 = 38/sin40

w = sin27*38/sin40

w = 26.84 ft

Angle x;

∡X = 180 - 27- 40 = 113º

Area;

A = 0.5*(26.84)*(38)*sin(113)

A = 469.42 ft²
