Well I just need to know a circle has a radius of 50 cm
Dear Gaby,
Well I would Say that <span>Any line that intersects a given circle at two different points is called a SECANT and </span><span><span>part of secant intercepted between these points is called CHORD</span> of a circle. So basically, </span><span>Both are very same. ... A Chord connects two points on the circumference of a circle. I hope I could help you my friend and Keep on Rockin'

we know the Inn is charging 155.82 and that's 100% plus 6%, namely 106% of an amout of say that is "x", being the 100%.
since we know that 155.82 is 106%, what is "x"?
Answer:
18.75 mg
Step-by-step explanation:
We can model this problem using the exponencial equation:
y = yo * (1 + r)^x
Where y is the final value, yo is the inicial value, r is the rate and x is the amount of time.
In this problem, we want to find y after x = 4 hours (from 9am to 1pm), we have yo = 300 and r = -0.5 (for every hour, half the caffeine leaves the body). So we have that:
y = 300 * (1 - 0.5)^4
y = 300 * 0.5^4
y = 300 * 0.0625
y = 18.75 mg
