Let x represent number of wrong questions answered by Aaron.
We have been given that Aaron is taking a multiple choice test with a total of 20 points available. Each question is worth exactly 1 point. We are asked to find Aaron's score (out of 20) if he got 6 questions wrong.
To find Aaron's score, we will subtract number of wrong answers from total score.
Therefore, Aaron's test scores would be 14 out of 20.
To find Aaron's score if he got x questions wrong, we will subtract x from total scores that is 
.
Therefore, Aaron's score would be , if he got x questions wrong.
Answer:
36 Hope this helps Im so sorry if this is wrong.
Step-by-step explanation:
36 x 0.10 = 3.6
36 + 3.6 = $39.60
To add and subtract fractions you must do the multiplication of the numerator of the first with the denominator of the second. Then, add or subtract the multiplication of the numerator from the second with the denominator of the first. Finally divide the result between the multiplication of the denominator of the first with the denominator of the second fraction.Annex the result.
In this problem, volume is computed:
volume = ∫(flow rate)·dt
.. = ∫[0, t] (3/10)*sin(2πt/7)·dt
= (3 / 10)*(7 /(2 π))*(-cos (2 π t/7)+1)
= (-21 / (20 π))*(cos (2 π t /7) - 1)
Volume is equal to 21 sin^2 (pit/7) / 10pi is the inhaled air in the lungs at time t
