Answer:
14
Step-by-step explanation:
Sin(∅) = Opposite angle ÷ hypotenuse.
Sin (45) = 7
÷ hypotenuse
hypotenuse = 7 ÷ sin(45)
*********************
Keep in mind
sin(45) = √2÷2
*********************
so we have: Hypotenuse = 7√2 ÷ (√2÷2)
Hypotenuse= 14.
Answer:
He will have 2,603.16 in a year.
Step-by-step explanation:
There are approximately 52 weeks in a year
52^2/25 = 108.16

Answer:
1732.2097 has 8 significant figures.
Step-by-step explanation:
Every non-zero digit is considered a significant number. Also, in some exceptional cases, zero can also be considered a significant figure if it is in the middle of two non-zero digits.
Just like in the number given, 1732.2097. We have 7 non-zero digits which certainly would be considered to be significant figures. Zero is between two significant figures, 2 and 9, therefore, it would also be referred to as a significant figure.
Therefore, the number, 1732.2097, has 8 significant figures.
