jeffrey's paycheck varies directly with the hours he works . when jeffrey works 5 hours , he gets paid $75.00. how much does jef
MrRissso [65]
Direct variations can be set up as proportions
5/75 = 8/x....5 hrs to 75 dollars = 8 hrs to x dollars
now we cross multiply
(5)(x) = (75)(8)
5x = 600
x = 600/5
x = 120 <== so he makes $120 for working 8 hrs

another way...
75/5 = 15..so he makes 15 per hr
15 * 8 = 120

The graph of (6-4x)^2/2x^2-5x+12 has a horizontal asymptote at y =
vova2212 [387]

Answer:

y = 8

Step-by-step explanation:

The given rational function is

y =  \frac{ {(6 - x)}^{2} }{ {2x}^{2} - 5x + 12 }

Let us expand the numerator to get;

y =  \frac{(6 - 4x)(6 - 4x)}{2 {x}^{2} - 5x + 12 }

y =  \frac{36 - 48x + 16 {x}^{2} }{2 {x}^{2} - 5x + 12 }

We can observe that, the degree of the numerator is the same as the degree of the denominator.

Therefore the horizontal asymptote is the ratio of the coefficient of the leading terms:

y =  \frac{16}{2}

The horizontal asymptote is

y = 8

A 450m long field is drawn to a scale 1cm to 90cm.find the lenth of drawing<br><br>​
irina1246 [14]

Answer:

500cm or 5 meters

Step-by-step explanation:

The ratio of drawing and field is 1:90.

So we have to make 450 m into cm.

450 -> is 45,000

Now we can make 2 fractions,

\frac{1}{90}=\frac{x}{45000}

Cross multiply

90*x = 90x

1*45000 = 45000

90x = 45000

Divide 90 to both sides

x = 500cm

<em>Thus,</em>

<em>the drawing's field is 500cm or 5m long.</em>

<em />

<em>Hope this helps :) </em>
