Answer:
Step-by-step explanation:
Let
x = cost for one adult
y = cost for one child
z = cost for one senior.
<u>The Reid family:</u>
take 2 adults and 2 children and paid 
that is 
, so
<u>The Mghee family:</u>
take 1 senior, 2 adults and 1 child and paid 
that is 
, so
<u>The Griffiths family:</u>
take 1 senior and 3 adults and paid 
that is 
, so
You get the system of three equations:
From the first equation:
From the third equation:
Substitute them into the second equation:
Then
Hence,
the cost for one adult is 
the cost for one child is 
the cost for one senior is 
<u>The Linton family</u> takes 1 senior, 2 adults and 3 children and paid
No they cant because 20 is not divisible by 75. One option that would work is 15 rows each with 5 people or vise versa. Hope this helped!
Answer/Step-by-step explanation:
Reference angle = θ
Opposite side = 11.9
Adjacent side = 10
Applying the trigonometric ratio, TOA, we have:
Tan θ = opp/adj
Tan θ = 11.9/10
θ = tan^{-1}(11.9/10)
θ = 49.9584509° ≈ 50.0° (to one d.p)
Apply pythagorean theorem to find AB:
Thus:
AB = √(11.9² + 10²)
AB = √241.61
AB ≈ 15.5 (to 1 d.p)
The answer is 4.8873, so you can say over 4 times as great, or almost 5 times as great for the first question.
And I think the second question could be because those over 35 years old have a more stable career, they're more developed skill-wise & worth more to their company so they're paid more, and of higher ranking in their professions, etc.
