The us census found at the population per square mile in the state rose from 128.7 to 191.3 during the last 10 years. by how much did the population grow per square mile

62.6 per square mile.

Step-by-step explanation:

The U.S. Census found at the population per square mile in the state rose from 128.7 to 191.3 during the last 10 years.

Population at initial year = 128.7

Population after 10 years = 191.3

Population grow per square mile = 191.3 - 128.7

                                                       = 62.6 per square mile.

Population grew 62.6 per square mile.

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

i think this could be a possible answer (1 / 84) -1

good luck! : d
