Answer:
3(percent): 75% 3(decimal): .75
4(percent):60% 4(fraction): 6/10 or 3/5, depending on wether or not you choose to simplify.
Answer:

Step-by-step explanation:
We are given that
Width of rectangle=b=2.1 cm
Length of rectangle=l=5.6 cm
We have to find the area of rectangle.
We know that
Area of rectangle=
Using the formula
Area of rectangle =
Area of rectangle=
Hence, the area of rectangle=
Answer:
In 50 years there'll be approximately 3582 elephants.
Step-by-step explanation:
If they are decreasing at a rate of 9% per year, it means it's population by year is:
population(0) = 400000
population(1) = population(0)*(100% - 9%) = population(0)*(91%)
population(2) = population(1)*(91%) = population(0)*(91%)*(91%) = population(0)*(91%)²
population(3) = population(2)*(91%) = population(0)*(91%)²*(91%) = population(0)*(91%)³
And so on, so the number of population as years passes is:
population(n) = population(0)*(91/100)^n
In this case we want to know the population of elephants when n = 50, so we have:
population(50) = 400000*(0.91)^50 = 3582.033
In 50 years there'll be approximately 3582 elephants.
The area of the sector is 42.4 feet and the area for the second is 50 :)
Any number times one will equal that number example 8956745×1=8956745 therefore 5×1=5 hope this helps
