Answer:
15.5 because you have to take away some point
Step-by-step explanation:
you can do 15.8 +5.3 and that would make 21 - 15 and makes 6 so you can round 15.8 to 16 and then you subtract to make 10 then you add 5
Answer:
48 ft^2
Step-by-step explanation:
5.5 times 6 equals 33 (larger square part)
2.5 times 6 equals 15 (two triangles combined so you dont have to 1/2)
Answer:

Step-by-step explanation:
This problem can be modeled by a linear function, where we have two points (37°C, 200) and (32°C, 150).
Notice that the temperature is the independent variable, because the heartbeat of the cat won't change the temperature, it works in the opposite way.
First, let's find the constant ratio of change.

This means the hearbeat of the car changes 10 pulses per minute each 1 celsius degree.
Now, we use the point slope formula to find the equation

Theerefore, the function that represents this situation is

Where
represents temperature and
represents hearbeats.
I'm pretty sure both B and C equal 12 as well
Since the triangle equals 180 and the angels are all congruent
The 1, 2, 3 I’m not sure bout the 4th one
