The temperature is 50 degrees fahrenheit. the temperature will decrease by 4 degrees f. each hour. let h be the number of hours. when will the temperature be below 32 degrees f.? (the pic has the options for the answer.)

Answers

Option B is correct

50-4h < 32

Step-by-step explanation:

Here, h be the number of hours.

As per the statement:

The temperature is 50 degrees Fahrenheit.

⇒Initial temperature = 50 degrees Fahrenheit

It is also given that:

The temperature will decrease by 4 degrees F each hour.

1 hour temperature will be = -4 degree F

then;

In h hour temperature =  -4h degrees F

We have to find the the temperature be below 32 degrees F.

Total Temperature be below 32 degrees F means:

50-4h < 32 where, h represents the number of hours.

Therefore, the  the temperature below 32 degrees F will be 50-4h < 32

Option B is correct

50-4h < 32

Step-by-step explanation:

Here, h be the number of hours.

As per the statement:

The temperature is 50 degrees Fahrenheit.

⇒Initial temperature = 50 degrees Fahrenheit

It is also given that:

The temperature will decrease by 4 degrees F each hour.

1 hour temperature will be = -4 degree F

then;

In h hour temperature =  -4h degrees F

We have to find the the temperature be below 32 degrees F.

Total Temperature be below 32 degrees F means:

50-4h < 32 where, h represents the number of hours.

Therefore, the  the temperature below 32 degrees F will be 50-4h < 32

The correct answer choice is B
