#2 i got 3.05 ft because 1/100 of 305 is 3.05
1+(21/100) = 1.21
15049 * 1.21 = 18209.29 (rounded to 18209)
The population was 18209
Hope this helps! :)
For this case we have:
Let:
- s: Profit from sales in a given week
- e: Seller's weekly profit

Where "c" represents the commission.
The commission on sales can be observed with the application of a rule of three:
s ---------> 100%
c ---------> 4%


Thus, e is given by:

Answer:
The equation that models the relationship between her sales in a given week, s, and her weekly earnings, e is:

Option d
The complete question in the attached figure
we know that
[area of a circle]=pi*r²
for r=1 unit
[area of a circle]=pi*1²---------> pi units²
if the area a full circle of 360°--------------> is pi
the area of sector 88°------------------------> X
X=88*pi/360--------> 0.77 units²
the answer is
<span>
the area of sector AOB is 0.77 units</span>

Answer:
The height of the tree in 2020 was of 19.63 feet.
Step-by-step explanation:
Exponential equation for growth:
The exponential equation for the growth of an amount has the following format:

In which H(t) is the amount after t years, H(0) is the initial amount and r is the growth rate, as a decimal.
A 4 foot tree was planted in 2012 outside a high school.
This means that 
The tree grew continuously by 22% each year from that point.
This means that 
Find out what the height of the tree was in 2020.
2020 is 2020 - 2012 = 8 years after 2012, so this is H(8).




The height of the tree in 2020 was of 19.63 feet.
