Answer:
B. 5
Step-by-step explanation:
We have been given that R varies directly with S. When S is 16, R is 80. We are asked to find constant of variation.
We know that two directly proportional quantities are in form , where,
k = Constant of variation.
Upon substituting our given values, we will get:
Therefore, the constant of variation is 5 and option B is the correct choice.
Answer:
Easy Peasy!
Step-by-step explanation:
First we have to set up our equation:
(Let x= Temp. after 5 days)
Sorry, have to define variables. If I didn't do it in Middle School Tests, I get an automatic 0 for that question.
So, let's solve!
(If you didn't know what I did there, I just multiplied the rate of the decreasing and increasing temperature by the number of days it was in effect)
So, the temperature during the fifth day is 58.2 degrees.
Hope this helps!
P.S. Stay Safe!
