Answer: $1,350
Step-by-step explanation:
45 hours x 10 dollars/hour = 45x10 dollars = 450 dollars/week
450 dollars/week x 3 weeks = 450x3 dollars = 1350 dollars
2 (an - 1) = 40
2an - 2 =40
2an = 40 - 2
2an = 38
2an/2 = 38/2
an = 19
Answer:
a: 17m + m
Step-by-step explanation:
Each one can answer 17 questions in 1 minute.
Each one can answer 17m questions in m minutes.
The total they can answer is 17m + 17m = 34m.
Every expression that is equal to 34m represents the amount they can both answer in the same number of minutes.
The expression we are looking for does not equal 34m.
a: 17m + m = 18m
b: 34m = 34m
c: 2(17m) = 34m
d: 17m + 17m = 34m
Only choice a does not equal 34m.
Answer: a: 17m + m
Answer:
√2/4 + 1
Step-by-step explanation:
sin 45° --> √2/2
cos 60° --> 1/2
tan 45° --> 1
with these values, we write a new expression
√2/2 × 1/2 + 1
√2/2 × 1/2 = √2/4
(by doubling the denominator, you are splitting the number in half as implied by the 1/2)
your answer is √2/4 + 1
goodluck :)
