Answer:
B. 57°F
Step-by-step explanation:
Given:
F = n/4 + 37
Where,
F = temperature in degrees Fahrenheit
n = number of times per minute crickets chirps
Find F when n = 80
F = n/4 + 37
F = 80/4 + 37
= 20 + 37
= 57
F = 57 °F
B. 57 °F
A1 = 6 a5 = -6
a1 + d(n-1) = -6
6 +4d = -6
4d = -12
d = -3
a3 = a2 + d = -6 -3 = -9
9 less than a number is <em><u>9 - n</u></em>
Where n is that number
Answer:
An hour and 30 minutes.
