From 10:00 am to noon, the rise in temperature is 4 degrees C, and from 3:00 pm to 5:00 pm, the fall in temperature is 6 degrees
lyudmila [28]

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

27 1/5 over 4/5 as a unit rate
REY [17]

Answer:

\frac{34}{1}  or 34

Step-by-step explanation:

we know that

To find the unit rate divide 27 1/5 by 4/5

but first

Convert mixed number to an improper fraction

27\frac{1}{5}=27+\frac{1}{5}=\frac{27*5+1}{5} =\frac{136}{5}

so

\frac{136}{5}:\frac{4}{5}=\frac{136}{4}=\frac{34}{1}

Given that cos 160= -q, express each of the following in terms of q:
GenaCL600 [577]
Hello,

cos 160°=-q

cos 20°=-cos 160°=q

sin 20°=√(1-q²)=sin 160°

tan -20°=tan 160=√(1-q²)/-q

cos 70°=sin 20°=√(1-q²)
