Answer:
22.5 Wands
Step-by-step explanation:
4 wands = 6 rands -> 6*4=24 so 4*4=16 -> 16 wands = 24 rands (1 wand=1.5 rand)
24 rands = 8 fands -> 24/8 = 3 -> 3 rands = 1 fand
3 rands means 1.5*3=4.5 -> 4.5 wands = 1 fand -> 4.5*5=22.5 wands
Answer:
10.75%
Step-by-step explanation:
Given that :
Population of orcas in 2018 = 465
Population in 2020 = 515
The per capita growth rate acn be calculated using the relation:
C
[(Population change / initial population) * 100]
Population change = population (2020 - 2018) = (515 - 465) = 50
[(50 / 465) * 100]
(0.1075268 * 100) %
10.7526%
= 10.75%
Answer:
6580 approx
Step-by-step explanation:
Given data
Population= 5000
Rate= 4%
Time = 7years
We are going to apply the compound interest formula
A=P(1+r)^t
substitute
A= 5000(1+0.04)^7
A= 5000(1.04)^7
A=5000*1.3159
A= 6579.5
Hence the population after 7 years is 6580 approx
