Answer: r=(-189)
first you subtract both sides by 8 and get -21=r/9
then you multiply 9 with each side and get -189 = r
you can check by rewriting the problem with -189 as r and solving the equation
Answer:
6.3 kilograms
Step-by-step explanation:
Because 1 kilo is 2.2 pounds, divide 13.86 pounds by 2.2 to get 6.3 kilograms
Answer:
P(0) = 7,917
Step-by-step explanation:
The population of the community is given by the following formula:
In which P(0) is the initial population and r is the growth rate.
The initial population P0 has doubled in 5 years.
This means that
Which lets us find r.
Applying the 5th root to both sides
So
Suppose it is known that the population is 12,000 after 3 years.
With this, we find P(0)
Step-by-step explanation:
is the required answer
Supplementary angles.
This is because supplementary angles are two angles that add up to 180 degrees, and these two angles would add up to 180 degrees.
