Answer:
4. b) 30
5. c) y=2/3x+9
6. y=2x-5
Step-by-step explanation:
Answer:
The answer is option D.
Step-by-step explanation:
cos M = adjacent / hypotenuse
From the picture
b is the adjacent
x is the hypotenuse
so
cos M = b/x

Fixed price costs
Crew salaries 350
fuel 120
overheads 170
Total fixed cost: 640
Variable costs per passenger
refreshments $ 6.50
refund $ 3.64
total variable cost: 10.14
Sales income
<span>Average ticket $ 36 .40
</span><span>Break-even point = <u> (fixed costs) </u>
(income per passenger – costs per passenger) </span><span>
</span>
Break even = 640 / (36.40-10.14) = 640 / 26.26 = 24.37
Answer:
The proof is given below.
Step-by-step explanation:
Given m∠AEB = 45° and ∠AEC is a right angle. we have to prove that EB divides ∠AEC into two congruent angles, it is the angle bisector.
Given ∠AEC=90° (Given)
∠AEC=∠AEB+∠BEC
⇒ 90° = 45° +∠BEC (Substitution Property)
By subtraction property of equality
⇒ ∠BEC = 90° - 45° = 45°
Hence, both angles becomes equal gives ∠AEB≅∠BEC
Since EB divides ∠AEC into two congruent angles, ∴ EB is the angle bisector.
