Answer:
The equations for the growth of two type of species are
H(m) = 12 + 2m
H(m) = 10 + 3m
Step-by-step explanation:
As given
The growth rate of two species of plants.
Species A is 12 cm tall and grows 2 cm per month.
The height of each species is represented by H(m) as a function of months m.
Than the equation becomes
H(m) = 12 + 2m
As given
Species B is 10 cm tall and grows 3 cm per month.
Than the equation becomes
H(m) = 10 + 3m
Than the equations for the growth of two type of species are
H(m) = 12 + 2m
H(m) = 10 + 3m
You want to leave a 15% tip on a meal that cost $65.00.
First, convert the 15% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 15%) by 100%.So, the conversational term "15%" becomes 15% / 100% = 0.15 in terms of a real mathematical number.
Second, you need to find out what 15% of your $65.00 meal cost is.This is always done by multiplying 0.15 by $65.00, or
0.15 x $65.00=$9.75.
So, the amount of tip you are going to leave is $9.75.
This makes the total cost of your meal (to write on your charge slip or other payment)
$65.00 + $9.75 = $74.75.
the ratio equal for 90:18
