Mr.jacobs budgeted $1,200 for tiles. His sketch of the floor requires him to use 38 white tile. each white tile cost $12. Write

Arturiano [62]

Given:
Budget for tiles = 1,200
number of white tiles = 38
unit cost of white tiles = 12
budget for brown tiles = x

cost of white tiles = 38 x 12 = 456

The inequality would be:

Cost of brown tiles + cost of white tiles < budget
x + 456 < 1,200

solving the inequality:
x + 456 < 1,200
 - 456 -456
x < 744

Mr. Jacobs can spend up to 744 for the brown tiles.

The pair of points is on the graph of an inverse variation. Find the missing value. (1.6, 6) and (8, y) 0.03 30 1.2 0.83

ZanzabumX [31]

One may note that (1.6 , 6) is just another way to say x = 1.6 when y = 6.

and that (8 , y) is another way to say x = 8 and y is who knows.

$\bf \qquad \qquad \textit{inverse proportional variation}\\\\
\textit{\underline{y} varies inversely with \underline{x}}\qquad \qquad y=\cfrac{k}{x}\impliedby 
\begin{array}{llll}
k=constant\ of\\
\qquad variation
\end{array}\\\\
-------------------------------$

$\bf \textit{we know that }
\begin{cases}
x=1.6\\
y=6
\end{cases}\implies 6=\cfrac{k}{1.6}\implies 6(1.6)=k\implies 9.6=k
\\\\\\
\qquad therefore\qquad \boxed{y=\cfrac{9.6}{x}}
\\\\\\
\textit{when x = 8, what is \underline{y}?}\qquad y=\cfrac{9.6}{8}$
