Answer:
156 square inches
Step-by-step explanation:
We are given the two quantities
Let
length = l = 13 inches
and
Width = w = 12 inches
The formula for the area of rectangle is:

where l is length and w is width
Putting the values of both that are given

so the area is 156 square inches ..
X=1
Subtract four so you get 1/x=1
Multiply by x
1x=1
Divide by 1
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.
3 times 4 is equal to 12
8 times 4 is equal to 32
therefore 3:8 is equal to 12:32
