Answer:
B. 90 degrees
Step-by-step explanation:
The definition of supplementary is that they add up to 180 degrees. If the measure of angle A is 90 degrees, then angle B is 180-90 = 90 degrees.
Answer: 14,533.79 don´t take my word for it
Step-by-step explanation:
So we have
120x2y5 and 80x3y2
120 doesnt divide into 80 evenly, but we know 40 goes into both.
so the first part is 80x
2y and 3y dont have a common factor other than y so the second part is
y
2 and 5 dont share any common factors so we simply leave that alone
so we have 40xy
Answer:
About 6,785 people will be infected about nine months.
Step-by-step explanation:
We can write an exponential function to represent the situation. The standard exponential function is given by:
Where <em>a</em> is the initial value, <em>r</em> is the rate, and <em>x</em>, in this case, is the time that has passed in months.
3,124 people have already been infected. Thus, our initial value <em>a</em> = 3124.
And an additional 9% will be infected per month. Therefore, our rate <em>r</em> will be 1 + 9% or 1.09.
Hence, our function is:
Then after nine months, the total amount of infected people will be f(9):

About 6,785 people will be infected about nine months.
