Answer:
27.3
Step-by-step explanation:
y=a(1/2)^t/h
Plug in
22=30(1/2)^t/61
Divide both sides by 30
0.7333333333=(1/2)^t/61
Log both
Log(0.7333333333) / Log(1/2)
0.447458977 = t/61
0.447458977 x 61 = t
27.2949976 to the nearest tenth is 27.3 = t
Simplified would be 4xy + 3x^2 + 6x

P=72
Answer:
(a) m<3 = 103 degrees
(b) m<4 = 77 degrees.
Step-by-step explanation:
A: The sum of the measures of all three interior angles in a triangle always is 180 degrees. Knowing this, we add the two known interior angles, 20 and 57, then subtract that from 180 to get 103 degrees.
B: The measure of an exterior angle is the sum of the two opposite interior angles. So, we add 57 and 20 to get the m<4 = 77 degrees.
