Response:
D
Step-by-step explanation:
90kg of sand was divided into 3 bags, constituting a total of 2+3+7=12 sections.
90kg/12=7.5kg
The smaller bag comprises 2 sections, hence it weighs 7.5kg*2=15kg
The medium-sized bag consists of 3 sections, leading to a total weight of 7.5kg*3=22.5kg
The larger bag encompasses 7 sections, resulting in a weight of 7.5kg*7=52.5kg
Thus, the ratio 2:3:7 translates to 15kg:22.5kg:52.5kg
Verifying, 15kg+22.5kg+52.5kg equals 90kg
THE CIRCLE EQUATION: (x - h)² + (y - k)² = r²
= (x + 1)² + (y - 4)² = 3
Answer:
Please refer to the explanation
Step-by-step explanation:
Provided parameters:
Initial population = 4000
Monthly increase = 170
Monthly decline in population = 70
Monthly growth rate in population (dt):
Starting population = 4000
Births per month = 170
However, there is a loss of 70 individuals monthly
Thus,
Births - Deaths (d) = 70
170 - d = - 70 (is there a decline?
170 + 70 = d
d equals the number of deaths
Per capita death rate:
Total deaths monthly / Initial population
= 240 / 4000
= 0.06
