20000x.05= 1000 added minnows per year, with the algae decline, we loose 750 minnows per year. 250 minnows are added every year. The rate 5% every year would be exponential growth, and the decline of 750 minnows per year is a result of a negative constant (not exponential decline.)
angle C = 90°
angle O = 67°
Step-by-step explanation:
Line AC is tangent to the circle at point C. Since OC is the radius, this means that OC is perpendicular to AC. Since the sum of the interior angles of a triangle is 180°, then
23° + 90 + angle O = 180°
or
angle O = 67°
Answer:
15
Step-by-step explanation:
Let the left side of the triangle be 2Y for the bigger triangle and then the smaller one will be Y.
Comparing the two triangle
2Y/Y = 30/X
2 = 30/X
Cross multiple
2X = 30
Dividing by 2
X = 30/2
X = 15
Answer: idk

Answer:
=
Step-by-step explanation:
A half rest is 2 beats, a quarter rest is 1 beat, so the rests on the left total 3 beats.
The half note on the right is normally 2 beats, but the dot adds half-again that amount, so 1 more beat. The dotted half note on the right is 3 beats.
Both represent 3 beats, so their beat counts are "equal."
