Start at 35 and start subtracting 4 (-4) then count each number so (35,31,27,23,19,15,11,7,3,-1) that’s 9 numbers so 1:00Pm +9 hours to 10:00PM and there you go

Suraj took a slice of pizza from the freezer and put it in the oven. The pizza was heated at a constant rate.
iragen [17]

Answer:

The pizza heats up an average of 7.50 degrees per minute

Step-by-step explanation:

The table shown

Time (minutes) Temperature (degrees Celsius)

1                          2.52

7                          47.547

13                          92.592

Since the pizza was heated at a constant rate, we can model the experiment as a line, where the slope represents how fast the pizza was heated

Slope

m   =  (y2 - y1)/(x2 - x1)

Let

(x1,y1) = (7, 47.547)

(x2,y2) = (13, 92.592)

m = (92.592 - 47.547)/(13-7)

m = 7.5075

The pizza heats up an average of 7.50 degrees per minute
