If ABCD is a square, then m∠A = 90°.
Therefore we have the equation:
30° + 48° + x° = 90°
78° + x° = 90° |-78°
x° = 12°
Answer: 12

300 total, divided by 10 is 30. 30 x each part of ratio gives:
30 x 7 = 210 - red
30 x 3 = 90 - yellow
210 - 90 = 120 more students
Answer:
-400
Step-by-step explanation:
We can find the rate of change by differentiating the population function:
P'(t) = 800 -2t
Then at t = 600, the growth rate is ...
P'(600) = 800 -2(600) = -400
The growth rate is -400 fish per day on day 600.
