I don't see Wen's work, but I'll show you mine!
We can create a set of coordinates for each of these sets of data, where x is the time in hours, and y is the number of degrees in Fahrenheit.
At time 0, the temp is 0: (0, 0)
5.75 hours late, the temp is -15.5: (5.75, -15.5)
We can find the change in temp per hour by using the slope formula, since slope is, after all, the rate at which something is changing.
That is rounded to the tenths place from -2.695652174 so you can round it however you need. What the interpretation of this number is is that temp is falling at a rate of 2.7 degrees F per hour.
She is wrong because 1and 1/3(2/6) + 1/6 = 1 and 3/6 or 1 and 1/2
πr² = π.5.5 = π25 units² or 78.5 units²
hope it helps...!!!

Answer:
R = 10 cm
Step-by-step explanation:
The area of a spherical shape is given by :
Where
r is the radius of the sphere
ATQ,
One large bubble separates into four small bubbles so that the total area of the small bubbles is equal to the area of the large bubble.
The radius of each small bubble is 5 cm
Using the given condition,
So, the radius of the large bubble is equal to 10 cm.
