Answer:
71°
Step-by-step explanation:
The cosine of an angle is equal to the sine of its complement:
cos(19°) = sin(90° -19°) = sin(71°)
Comparing to the given expression, we see that x = 71°.
Answer:
We can estimate a population of 500 birds.
Step-by-step explanation:
We can estimate the total bird population using a rule of three with the information given:
If we find 5 birds with the foot band among 100 birds captured, how many birds there are in total if inicially we put foot bands in 25 birds?
5 birds with foot band -> 100 birds captured
25 birds with foot band -> X total birds
X * 5 = 25 * 100
X = 25 * 100 / 5 = 500 birds
We can estimate a population of 500 birds.
Hello!
Let's put this as a system of equations.
r= 8+g
r+g=14
Let's plug our r value into the second equation and solve for g.
8+g+g=14
8+2g=14
Now we subtract 8 from both sides.
2g=6
We divide both sides by 2.
g=3
Therefore, he has 3 green peppers.
I hope this helps!
