Answer:
-62/23 degrees per hour
Step-by-step explanation:
Do this by dividing the total change in temperature (-15 1/2 degrees) by the total elapsed time (5 3/4 hrs):
-31/2 degrees -62/4 degrees Note: convert 31/2 to 62/4
--------------------- = ------------------------ = -62/23 degrees per hour
23/4 hrs 23/4 hrs
Answer:
27.7m
Step-by-step explanation:
Step 1
We find the Circumference of the nylon thread.
The formula = 2πr
The diameter of the thread = 0.88m
Radius = Diameter/2
= 0.88m/2
= 0.44m
Circumference = 2 × π × 0.44m
= 2.7646015352m
Approximately = 2.765m
Step 2
We calculate the distance
Number of revolutions = 10
Therefore, the Distance or how far the metal weight can travel =
Circumference of the wheel × Number of revolutions
= 2.765m × 10
= 27.65m
Approximately to 1 decimal place = 27.7m
Answer:
20
Step-by-step explanation:
u-t = 2
u+t= 5
(u-t) (u²-t²)
(u-t) (u-t) (u+t) (a²-b²= (a+b) (a-b))
put the values
(2)(2)(5)
=20
