Answer:
68 adult tickets and 40 child tickets were sold.
Step-by-step explanation:
Create a system of equations where a is the number of adult tickets sold and c is the number of child tickets sold:
8a + 5c = 744
a = 2c - 12
Solve by substitution by substituting the second equation into the first one:
8(2c - 12) + 5c = 744
16c - 96 + 5c = 744
21c - 96 = 744
21c = 840
c = 40
So, 40 child tickets were sold. Plug this into the second equation to solve for a:
a = 2c - 12
a = 2(40) - 12
a = 80 - 12
a = 68
So, 68 adult tickets and 40 child tickets were sold.
Answer:
50.24
Step-by-step explanation:
area of a circle = pi r^2
substitute 3.14 for pi
3.14*(8/2)^2
3.14*4^2
3.14*16
50.24
The BAC of the female is an illustration of proportion
- The BAC after consuming the three drinks is 0.029w
- The BAC three hours after consuming the drinks is 0.087 w
<h3>How to calculate the BAC?</h3>
BAC is calculated using:
BAC = Alcohol consumed/(Body Weight * R)
The weight is given as:
Body weight = 140 lb
Convert to kg
Body weight = 63.5 kg
For female
R = 0.55
So, we have:
BAC = Alcohol/(63.5 * 0.55)
BAC = Alcohol/34.925
BAC = 0.029Alcohol
The weight or volume of the alcohol consumed is given.
So, we represent it with w.
BAC = 0.029w
Hence, the BAC after consuming the three drinks is 0.029w
<h3>How to calculate the BAC after 3 hours?</h3>
We have:
BAC1 = 0.029w
Time (t) = 3 hours
The BAC after 3 hours is
BAC = BAC1 * (t - 0.015)
So, we have:
BAC = 0.029w * (3 - 0.015)
Evaluate the product
BAC = 0.087w
Hence, the BAC three hours after consuming the drinks is 0.087 w
