<h3>Jon earned $38,000 last year . He paid $6,840 for entertainment what percent of his earnings did Jon pay in entertainment expenses?</h3>
We can establish a proportion:
If $38,000 is => 100%
Then $6,840 is => P%
P% = $6,480 x 100/$38,000 = 18%
Answer = 18 %
Answer:
It'll take 12 minutes to be at 30 degrees.
Step-by-step explanation:
Since the metal is cooling at a linear rate then the rate of degrees per minute should be the through the cooling process. From 4 minutes to 7 minutes there was a span of 3 minutes and in that time the metal cooled 105 degrees. So the metal is cooling at a rate of
rate = 105/3 degrees/minute = 35 degrees/min
To reach 30 degrees from 205 it should cool down an additional 175 degrees so it'll take:
minutes = deegrees/rate = 175/(35) = 5 minutes
Since the metal had a temperature of 205 degrees in 7 minutes, then it'll take 12 minutes to be at 30 degrees.

<em>Standard form:</em>
1. y = x² - 4x - 5
2. y = x² - 2x - 8
3. y = x² + 4x - 21
4. y = x² + 12x + 20
5. y = x² + 8x + 12
6. y = x² + 4x + 3
7. y = x² - 8x + 7
8. y = x² - 6x + 8
9. y = x² + 10x - 11
