A balance is used to measure mass.
Answer:
YES
Step-by-step explanation:
Any line that is tangent to a circle is always perpendicular to the radius of the circle, forming a right angle at the point of tangency.
Therefore, ∆BAC is a right triangle if it satisfy the pythagorean triple rule which says that c² = b² + a²
Where,
c = the hypotenuse = 30
b = 24
a = 2(9) = 18
Thus:
30² = 24² + 9²
900 = 900 (this is true)
Therefore, line AB is tangent to circle O.
The answer is YES
Answer:
c

Answer:
There were 125 shoppers on the first day.
Step-by-step explanation:
Let us call the number of shoppers on the first day 
, then on the <em>n</em>th day the number of shoppers 
is
which is a geometric series whose sum to the<em> n</em>th term is
Now, we know that the total number of shoppers over the first 4 days is 671; therefore,
Thus, there were 125 shoppers on the first day.
