P(9) is p9 or 9p (I think)
<span>a = (90-a)/2 - 18
this means that the angle equals half its complement minus 18 degrees.
this means the same as the angle equals 18 degrees less than half its complement.
solve for a.
equation is:
a = (90-a)/2 - 18
simplify by removing parentheses to get:
a = 90/2 - a/2 - 18
simplify further to get:
a = 45 - a/2 - 18
combine like terms to get:
a = 27 - a/2
add a/2 to both sides to get:
a + a/2 = 27
multiply both sides of the equation by 2 to get:
2a + a = 54
combine like terms to get
3a = 54
divide both sides of the equation by 3 to get:
a = 18
your answer should be that the angle is equal to 18 degrees.
if the angle is 18 degrees, then its complement is equal to 90 - 18 = 72 degrees.
half its complement is equal to half of 72 is equal to 36 degrees
18 degrees less than that is equal to 36 - 18 is equal to 18 degrees.
Your answer is that the measure of the angle is 18 degrees.</span>

Answer: 1) D
2) C
Step-by-step explanation:
1. The blue algae has an initial mass of 20 kg and doubles its mass every hour. Then after t hours, the mass of blue algae is
2. The green algae has an initial mass of 160 kg and grows at a constant rate of 0.20 kg per minute. Then after t hours (60t minutes), the mass of green algae is
Part I) At t=3:
The mass of green algae has 196-160=36 kg more mass at 3 hours.
Part II) At t=4:
The blue algae has 320-208=112 kg more mass at 4 hours.
