Answer:
s = 10
Step-by-step explanation:
Given s is inversely proportional to t , then the equation relating them is
s = ← k is the constant of proportion
To find k use the condition when s = 0.6, t = 5
0.6 = ( multiply both sides by 5 )
3 = k
s = ← equation of proportion
When t = 0.3, then
s = = 10
Answer:
Step-by-step explanation:
Basically the word problem here is trying to get us to find the line using the two points (113,70) and (173,80).
It also tells us by saying that we're modeling the temperature that we're going to be using the y = mx + b formula. m and b are what we'll mainly be looking for.
Let's start by finding m, the slope. We'll be using the point slope formula:
So m = 1/6.
Now let's use that m and choose one of the points (I chose (113,70) ) to plug in everything but b in the original formula
so now that we know our b and our m, we can plug those into the original equation to get our answer!
