Answer:
a. The Mexican Airline offers a better deal for 9 students to travel.
b. 10 students
Step-by-step explanation:
a. The Mexican Air airline offers a round trip airfare of $250 per person.
So, for 9 students the fare will be total $(250 × 9) = $2250
Now, the Fiesta airline offers a round trip airfare of $150 per person if the club agrees to pay a one-time group rate processing fee of $1000.
So, for 9 students the total fare will be = $[1000 + (150 × 9)] =$2350.
Therefore, the Mexican Airline offers a better deal for 9 students to travel. (Answer)
b. Let for x students both the airline offers the same total costs.
Then we can write
250x = 1000 + 150x {From the conditions given}
⇒ 100x = 1000
⇒ x = 10
So, if the number of students is 10, then only both the airlines will take same fare. (Answer)
Answer:
x = 100
Step-by-step explanation:
the sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
52 + 28 + x = 180
80 + x = 180 ( subtract 80 from both sides )
x = 100
I hope this helps you
16x+4=110+3x+11
13x=117
x=9
Step-by-step explanation:
1. So first you have to cross multiple the two terms
2.Solve the algebraic equation
By dividing with 12 on both sides
(Note :That's a 32 in the picture sometimes i really write bad)
We have the following kinematic equations that model the problem:
steam boat:
r1 = (36.8) * t
speed boat:
r2 = v * (t-1.75)
The distance between the boats is:
d = r2-r1 = v * (t-1.75) - (36.8) * t
Substituting t = 1.8 and d = 86.9 we have:
86.9 = v * (1.8-1.75) - (36.8) * 1.8
We clear the speed:
v = (86.9 + (36.8) * 1.8) / ((1.8-1.75))
v = 3062.8 Km / h
Answer:
the speed boats speed in km / h is:
v = 3062.8 Km / h
