Sally earns per hour = $12
Sally works for in a week = 16 hours.
So, Sally earns in a week = 
Sally can save money each week= 20% of 192

A. How much does she earn each week ? Sally earns $192 in a week.
B. How much money will she save each week? Sally will save $38.40 each week.
C. How much money will she save each month (assume there are 4.3 weeks in a month)
Savings of 1 week = $ 38.40
Savings of 4.3 weeks = 
Hence, she will save $165.12 in a month.
D. How many months will it take her to save the money?
Total money needed = $1800
Number of months needed to collect this amount =

Hence, it will take 11 months approx to save $1800.
Answer:
7
Step-by-step explanation:
Answer:
To prove that ( sin θ cos θ = cot θ ) is not a trigonometric identity.
Begin with the right hand side:
R.H.S = cot θ =
L.H.S = sin θ cos θ
so, sin θ cos θ ≠ 
So, the equation is not a trigonometric identity.
=========================================================
<u>Anther solution:</u>
To prove that ( sin θ cos θ = cot θ ) is not a trigonometric identity.
Assume θ with a value and substitute with it.
Let θ = 45°
So, L.H.S = sin θ cos θ = sin 45° cos 45° = (1/√2) * (1/√2) = 1/2
R.H.S = cot θ = cot 45 = 1
So, L.H.S ≠ R.H.S
So, sin θ cos θ = cot θ is not a trigonometric identity.
Answer:
$29.67
Step-by-step explanation:
first you would fin out how much the total would be with the sales tax( which is equal to $4.89) added to the initial cost which should add up to $77.39
the 15% tip would add $11.61 to the $77.39
divide 89 by 3 which should give you 29.67
You add up all of the Frequencies together (to get 50)
The number 6 was rolled 9 times. So that makes it 9/50.
9/50 -> .18 or 18%
Does that help?
