Twenty percent of a radioactive substance decays in ten years by what percent does the substance decay each year

kifflom [539]

Answer:

Step-by-step explanation:

20% takes 10 years to decay

To find per year decay, we divide the percentage by the number of years, so we get unit rate of years {per year]. Thus we have:

20%/10 = 2% per year

It's that simple.

Hence, the percentage by which the substance decays each year is 2%

Papessa [141]

Answer: 75 minutes per hour.

Step-by-step explanation:

From the question, we are informed that Marion is driving between two towns that are close together and that she drives 1/5 the distance of the trip in 15 minutes.

The rate per hour will then be:

= 15 ÷ 1/5

= 15 × 5

= 75 minutes

The rate per hour will then be 75 minutes per hour.

The graphs below are based on government data on unemployment for 2017.

lord [1]

You already got the first two questions right: the group with the highest number of people unemployed / unemployment rate is the one with the highest bar in the respective histogram.

The two graph are related in this sense: take the first age group as reference. We know that 700 people from 16 to 19 are unemployed, and that those people represent 14% of the population, then we know that the 14% of the population between 16 and 19 is 700.

We can deduce that, if x is the number of people between 16 and 19, we have

$\dfrac{14}{100}x=700 \iff \dfrac{7}{50}x=700 \iff \dfrac{x}{50}=100 \iff x=5000$

So, by the relation between the two graphs, we can deduce the total population for each age group.
