I believe either a or c is incorrect because with A the total number of walks would have to continue all of the way until 54. And i dont completely understand C. The wrong one i think is b.
Answer:
60.
Step-by-step explanation:
As 80% of the 7th graders like hot chocolate which is equivalent to 60 people.
Answer:
Complementary Angles: The angle with 32˚ and 48˚
Supplementary Angles: The angle that is together with the angles of 107˚ and 73˚
Neither: The angle with 101˚ and 77˚ since
Step-by-step explanation:
Complementary angles are angles that sum up to 90˚ so 32 plus 48 is 90 which makes it a complementary angle.
Supplementary angles are angles that sum up to 180˚ so 107+73 is 180 which makes it a supplementary angle.
To find the angle with "neither" Complementary nor Supplementary you use the process of elimination
Hope this helps!
The equation which represents a population of 490 animals that decreases at an annual rate of 20% is;
![P(x)=490(1+0.20)^{x}](https://tex.z-dn.net/?f=P%28x%29%3D490%281%2B0.20%29%5E%7Bx%7D)
<h3>What is exponential function?</h3>
When the input variable x appears as an exponent in the formula
the exponential function is indicated.
The exponential curve is influenced by both the exponential function and thus the value of x.
where, a = initial value.
b = 1 + r (rate of increase or decrease)
The animals' original population is indicated here by: 490
Thus, a = 490
Additionally, 20% is the rate of increase.
So, r = 20%
r = 0.20
As a result, the population function, or the number of animals in a population, is as follows:
![P(x)=490(1+0.20)^{x}](https://tex.z-dn.net/?f=P%28x%29%3D490%281%2B0.20%29%5E%7Bx%7D)
