Answer:
15
The factors of 30 are: 1, 2, 3, 5, 6, 10, 15, 30
The factors of 45 are: 1, 3, 5, 9, 15, 45
The factors of 90 are: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90
Then the greatest common factor is 15.
x= π or x=π/2, 3π/2
Step-by-step explanation:
Note that the sine wave is shifted up by 1/2 and the peak is at 5/2 so subtract the 1/2 from the 5/2 to get the amplitude of this wave.
It's 2
She will pay $1,152 in four years?
16% as a decimal is 0.16
Multiply that by the 1800 to get the interest for one year.
0.16×1800=288
288 is the interest for one year, but you need the amount for four years.
Multiply 288 by 4.
288×4=1152
