X^3=8
x^3=2^3
Therefore, x=2
Answer:
2.9
Step-by-step explanation:
x+3.2=6.1
x=6.1-3.2
x=2.9
Use the rule of 3 simple
1680 beats ------- 60 min.
x beats -------------- 1 min.
----------------------------------
x = (1680*1)/60 = 1680/60 = 168/6 = 28 beats per minute

Answer:
(a) 2 degree celsius per hour
(b) 3 degree celsius per hour.
Step-by-step explanation:
From the question,
(a) Avearge rate of rise in temperature per hour(T') = Rise in temperature(T)/Time required for the rise(t).
T' = T/t.................... Euqation 1
Rise in temperature (T) = 4 degree celsius, t = 10.00 am to noon = 2 hours.
Substitute into equation 1
T' = 4/2
T' = 2 degree celsius per hour.
(b) Also,
Average rate of fall in temperature per hour (T') = Fall in temperature (T)/Time(t)
T' = T/t
Given: T = 6 degree celsius, t = 3:00 pm to 5:00 pm = 2 hours
T' = 6/2
T' = 3 degree celsius per hour
