1. A population of 20 rabbits is released into a wildlife region. The population is growing at a rate of 60% per year. What is the population of rabbits after 8 years and what equation did you use? 2. The population of white rhinos in 2001 was 11,670. The population is declining by 9% each year. What is the population expected to be in the year 2021 and what equation did you use?

1. 116 2. 0 or -9246

Step-by-step explanation:

1. 20 = 100%

so 20/10 = 2 meaning 2 equals 10%

now 2 x 6 (60%) = 12

12 x 8 years = 96

20 + 96 = 116

2. 11,760 = 100%

1% of 11,760 is 116.7 (11,760/100)

116.7 x 9 (9%) = 1050.3

2021 - 2001 = 20

so 1050.3 x 20 years = 21006

11,760 - 21006 = -9246

now since there cant be negative animals you could write that as 0

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
