Step-by-step explanation:
A mine worker discovers an ore sample containing 500 mg of radioactive material. It is discovered that the radioactive material has a half life of 1 day. Find the amount of radioactive material in the sample at the beginning of the 7th day.
Answer:
7.8125 or 7.8
Step-by-step explanation:
[tex]gm=(1/2)^{n-1}[/tex]
[tex]gm=500 (1/2)^{ 7- 1} \\gm= 500 (1/2)^{6}[/tex]
= 7.8125 or 7.8
The amount of radioactive material in the sample at the beginning of the 7th day is 3.906 milligram.
What is Half life of an Element?Half life of an element is the time taken by a radioactive substance to break down into half the quantity of the initial quantity.
In other words, we can say that it is the time for an element to disintegrate half of it's atoms.
Given that,
Half life of radioactive material is 1 day.
Initial amount of the substance = 500 mg
At the beginning of the first day, there will be 500 / 2 = 250 mg os substance.
Taking the first term as 250 and the common ratio as 1/2, we can consider this as a geometric sequence.
nth term of a geometric sequence = a rⁿ⁻¹, where a is the first term and r is the common ratio.
At the beginning of seventh day,
Amount of radio active substance = 250 (1/2)⁷⁻¹ = 3.90625
Hence the amount at the beginning of seventh day is 3.906.

How does the decimal point move when multiplying 79.816×103?
Answer:
8221.048
Step-by-step explanation:
Answer:
It moves two places to the right
Step-by-step explanation:
Lets pretend we are multiplying my 100 instead of 103. That has two zeroes, so 79.816 would turn into 7981.6
If we did multiply by 103, the answer would be 8221.048, which is still two places to the right

Kiley and her parents traveled to visit her grandmother. They drove 24.3 miles from their house to the airport in hour. At the airport, they exited the car and walked for hour to the waiting area by the gate to board their plane. Their walk covered 1.2 miles. From the waiting area, they walked another 0.1 mile to board the plane. The plane left the gate 45 minutes after they arrived at the waiting area. The plane flew 346 miles in hours. After the plane landed, Kiley and her parents walked for 30 minutes, covering 1.1 miles, before they found a cab. It was a 15-minute cab ride to get to Kiley’s grandmother’s house, which was 12.3 miles away.
