Answer:
GCF(330, 75, 450, 225) = 15
Steps:
Prime factorization of the numbers:
330 = 2 × 3 × 5 × 11
75 = 3 × 5 × 5
450 = 2 × 3 × 3 × 5 × 5
225 = 3 × 3 × 5 × 5
GCF(330, 75, 450, 225)
= 3 × 5
= 15
The answer is b cause none of x is the same number
Cot x = cos x / sin x
cot π/4 = cot 45° = cos 45° / sin 45°
We know that sin 45° and sin 45° have the same value:
cos 45° = sin 45° = √2 / 2;
cos 45° / sin 45° = √2/2 : √2/2 = 1
Answer:
cot π/4 = 1
There are a couple of things you didn't mention.
In order to come up with an answer to the question,
I have to assume reasonable numbers for them, and
then answer the question that I have invented.
Assumption #1: Each day that you work, you work for 8 hours.
Assumption #2: You work for three days each week.
If those assumptions are true, then you earn
($7.25 / hour) x (8 hours/day) x (3 days/week) x (2 weeks) =
($7.25 x 8 x 3 x 2) = $348 before taxes and other deductions.
