The temperature fell 36oF in 9 hours. If the temperature fell at the same rate every hour, which represents the change in temperature each hour?

4°F

Step-by-step explanation:

If the temperature fell 36°F in 9 hours, then;

36°F= 9hours

to get the change in temperature in 1 hour, we will say;

x°F = 1 hr

Since we have

36°F= 9hours

x°F = 1 hr

Cross multiply

9x = 1*36

9x = 36

x = 36/9

x = 4°F

Hence the change in temperature each hour is at 4°F

-81 -56 -27 0 81

step-by-step explanation:

22, 28, 34, 40, 46

b)   f(n) = 6n + 16

n = what is the number of the row ( 22 would be row 1) so if we replaced n with 1, we would get 22

c)   the 14th row will have 100 seats

(1)   (2)   (3)   (4)   (5)   (6)   (7)   (8)   (9)   (10) (11) (12) (13) (14)

22 | 28 | 34 | 40 | 46 | 52 | 58 | 64 | 70 | 76 | 82 | 88 | 94 | 100
