Let
x--------> <span>represents the length of a single tile
L-------> t</span><span>he length of the floor
W------> the</span><span> width of the floor
A--------> </span>area of a tiled kitchen floor
<span>
we know that
A=W*L
A=</span>4x²<span> + 24x + 27
</span>so
W*L=4x² + 24x + 27---------> equation 1
L=2x+9------> equation 2
substitute equation 2 in equation 1
W*[2x+9]=4x² + 24x + 27
W=[4x² + 24x + 27]/[2x+9]
therefore
the answer is
the <span>expression that represents the width of the kitchen in terms of x is
</span>W=[4x² + 24x + 27]/[2x+9]
Perpendicular slopes are oposite inverse, ie. the slopes of perpendicular lines multiply to get -1
8 times -1/8=-8/8=-1
the slope is -1/8
Answer:
x=10
y=30
Step-by-step explanation:
x=-2y+70
x=-2*3x+70
x=-6x+70
7x=70
x=10
y=3x
y=3*10
y=30
However, the dosimeter is actually worn by the worker to determine the personal noise dose during the workshift or sampling period (Figure 21). Noise dosimetry is a form of personal sampling, averaging noise exposure over time and reporting results such as a TWA exposure or a percentage of the PEL.
The number of hits a player would expect to get in 200 at bats is: 42
x:200
x/200 = .2121212121...
200(x/200) = 200(.2121212121...)
x = 42.4242...
