Answer:
<h2>c=35+0.23m</h2>
Step-by-step explanation:
Given that Nadya's uses the service for up to 200 times then
let let c represent the cost of Nadya's bill
and m be the minutes of airtime
therefore
the initial charger is $35
The charge per additional minutes is $0.23
c=35+0.23m
Therefore the expression is
c=35+0.33m
Answer:The answer would be $8
Step-by-step explanation:
If you add up all the things she is buying and then subtract it from $43 that would be the difference. She spent $35
Minor base: b=19 inches
Height: h=12.6 inches
Major base: B=29.2 inches
Area of the trapezoid: A
A=(b+B)h/2
Replacing the values:
A=(19 inches + 29.2 inches) (12.6 inches) / 2
A=(48.2 inches) (12.6 inches) / 2
A= (607.32 inches^2 ) /2
A= 303.66 inches^2
Answer: The area of the trapezoid is 303.66 square inches
Answer:
x + y ≤ 300
7.50x + 5.50y ≥ 2000
Step-by-step explanation:
It is given that the theater hall has 300 seats.
If there are x adults and y children then they must satisfy the following inequality that
x + y ≤ 300 ...... (1)
Now, it is also given that the charge for tickets for adults is $7.50 per ticket and that for children is $5.50 per ticket and the theater expects to make at least $2000 for each show.
Therefore, the following inequality can be written as
7.50x + 5.50y ≥ 2000 ....... (2)
Hence, the inequality equations (1) and (2) can be written from the given data. (Answer)
