A toxic radioactive substance with a density of 2 milligrams per square centimeter is detected in the ventilating ducts of a nuc

Zolol [24]

Answer:

60.5 milligrams per square centimeter First, determine how many half lives have expired by dividing the time by the half-life. So: 55/20 = 2.75 That means that only 2^(-2.75) = 0.148650889 = 14.8650889% of the original substance remains. So just divide the amount remaining by 0.148650889 to get the original amount. 9 / 0.148650889 = 60.5445419 So originally, there was 60.5 milligrams per square centimeter 55 years ago.

A bowl in the shape of a hemisphere has a volume of 144π cubic centimeters. What is the radius of the bowl?

Alla [95]

Answer:

6 = r

Step-by-step explanation:

V = $\frac{2}{3}$ πr³ Use this equation to find the volume of a hemisphere

144π = $\frac{2}{3}$ πr³ Divide both sides by $\frac{2}{3}$ π

216 = r³ Take the cube root of both sides

6 = r
