Answer:
x = 85°, y = 30°
Step-by-step explanation:
40° + x + 55° = 180°
x + 95° = 180°
x = 85°
85° + 65° + y = 180°
150° + y = 180°
y = 30°
Answer:
B
Step-by-step explanation:
quantity eleven times y = 11y.
quantity three times x = 3x.
the first one over the second one would be 11y/3x, and B is the answer that shows this.
Answer:
Every day, the locust population grows by a factor of 1.30.
Step-by-step explanation:
"Complete the following sentence about the daily rate of change of the locust population."
The population of locusts changes exponentially. Initially, there are 1100 locusts. Every 2.4 days, the population increases by 87%. So the equation L(t) is:
L(t) = 1100 (1.87)^(t/2.4)
After 1 day, the population is:
L(1) = 1100 (1.87)^(1/2.4)
L(1) = 1428
Compared to the initial 1100, the population increases by a factor of:
1428 / 1100 = 1.30
Since the daily rate of change is greater than 1, the population grows.
