Step-by-step explanation:
if you're asking what the new temperature would be.
then -5 -8=-13
Step 1:
Convert the electricity per hour in kilowatts,
Electricity per hour = 20 watts
=20/1000 kilo,watts
Step 2:
The electricity consumes in 5 hour is ,
Electricity in 5 hour = 5x 20/1000 kilo watts.
Obtain the cost as,
=5x20/1000x10
=1 Cent
Answer: =1 Cent

Answer:
C
Step-by-step explanation:
The volume (V) of a cone is calculated using the formula
V =
πr² h
where r is the radius and h the perpendicular height
here r = 5 and h = 6, hence
V =
× π × 5² × 6
= 2π × 25 = 50π m³ → C
a b and c are all correct answers
