Answer:
r = radius of circle
Step-by-step explanation:
The circumference of a circle is given by :
C = 2πr
Where
r is the radius of the circle
In this problem, we need to say that what does r represents in the given formula. It means we can say that r stands for the radius of the circle.
Answer: 40%
Step-by-step explanation:
Since 20 beings preferred Freon juice to all other juices and there were 50 people that were surveyed, the percentage of those that preferred Freon Juice will be:
= Those that preferred Freon Juice / Total number surveyed. × 10
= 20/50 × 100
= 40%
Answer:
(-2) *6 = -12
Step-by-step explanation:
4 + (2-4) *6 , solve the subtraction in parenthesis
4 + (-2)*6, solve the multiplication of (-2) *6
4 - 12, solve the subtraction
-8
Use Law of Cooling:

T0 = initial temperature, TA = ambient or final temperature
First solve for k using given info, T(3) = 42

Substituting k back into cooling equation gives:

At some time "t", it is brought back inside at temperature "x".
We know that temperature goes back up to 71 at 2:10 so the time it is inside is 10-t, where t is time that it had been outside.
The new cooling equation for when its back inside is:

Solve for x:

Sub back into original cooling equation, x = T(t)

Solve for t:

This means the exact time it was brought indoors was about 2.5 seconds before 2:05 PM
