The answer is B: 150
Let a be the age at which the tree reaches maturity
289000 = 900a + 2200(220-a)
289000 = 900a + 484000 - 2200a
289000 - 484000 = -1300a
a = -19500 / -1300
a = 150
A = c/sin C, and b by the proportion b/sin B = c/sin C.
a/sin 37° = 4380/sin 109°
a sin 109° = 4380 sin 37°
a = 4380 sin 37°/sin 109° ≈ 2787.8
b/sin 34° = 4380/sin 109°
b sin 109° = 4380 sin 34°
b = 4380 sin 34°/sin 109° ≈ 2590.4
There are an infinite number of solutions to this linear equation in two variables. It will graph as a straight line.
In standard form, the equation would be written
.. 105x +56y = 30
Answer:
10 points
Step-by-step explanation:
since they only said 5 days and each day 2 points drop.
1 day = 2 points
5 days = 2 x 5 = 10 points
Answer:
Step-by-step explanation:
These are physical measurements, which must be zero or greater. These restrictions are the reason for your having a total of four inequalities.
