Answer:

39858075

Step-by-step explanation:

Hello,

One basic way to see it is to compute the values.

75 = 25 * 3

225 = 75 * 3

675 = 225 * 3

etc ...

We can notice that this is multiplied by 3 every 10 years so we can compute as below.

year population

1970 25

1980 75

1990 225

2000 675

2010 2025

2020 6075

2030 18225

2040 54675

2050 164025

2060 492075

2070 1476225

2080 4428675

2090 13286025

2100 39858075

So the correct answer is 39858075

Hope this helps.

Do not hesitate if you need further explanation.

An element with mass 130 grams decays by 22% per minute. How much of the element is remaining after 7 minutes, to the nearest 10

shepuryov [24]

22.8 grams of element will be remaining after 7 minutes

Further explanation:

Given

$Mass\ of\ element=130g\\Percentage\ of\ reduction=22\%$

The element reduces (1-22%) in one minute.

The process will be repeated 7 times for 7 minutes

If we have to calculate the amount of element after 7 minutes

then the total reduction will be: (1-22%)^7

$Remaining\ amount=130*(1-22\%)^7\\=130*(1-0.22)^7\\=130*(0.78)^7\\=130*0.18\\=22.84g\\Rounding\ off\ to\ nearest\ tenth\\=22.8g$

22.8 grams of element will be remaining after 7 minutes
