Answer:
120 miles per hour
total time 3 hours
120 x 3= 360
the plane travels 360 miles
Step-by-step explanation:
Answer:
The answer to your question is: 20 hours.
Step-by-step explanation:
Data
Hortencia = $350
Alex $18 / h
# hours Alex must paint to make more money than Hortencia = ?
Process
Equation 18 x n > 350
n > 350 / 18
n > 19.4 hours
If Alex work 19.4 hours, he will make the same amount of money than Hortencia, then He needs to work 20 hours.
I think you're asking for a numerical answer, but you didn't mention
your score on the final.
Since the final is worth 10% (one tenth) of the grade, that 71 that you
have going into the final is worth 9/10 of the grade. So the way you
calculate your overall average is
Overall score = 1/10 of [ (71 x 9) + score on the final ] .
If you scored absolute zero on the final, your overall average would be
Overall score = (1/10) x [ (71 x 9) + 0 ] = (1/10) (639) = <u>63.9%</u> .
That's the lowest overall score for the class that you can have.
The <u>highest</u> overall score you could have would be if you got 100% on the final.
Then
Overall = (1/10) x (639 + 100) = (1/10) x (739) = <u>73.9%</u> .
If you got a 50% on the final, your overall would be
(1/10) x (639 + 50) = (1/10) x (689) = <u>68.9%</u> .
In general, your overall score for the class, after the final, is going to be
63.9% plus (1 tenth) of your score on the final.
Good luck !
So first subtract 20 from both sides of the equation.
3x-4=35
now add 4 to both sides.
3x=39
now divide both sides by
x=13
