Use the formula upper f equals nine fifths upper c plus 32 to convert negative 25 degrees c to degrees fahrenheit. what formula gives the conversion from degrees fahrenheit to degrees celsius?
a. c=f-32-(5/9)
b. c=(5/9)(f-32)
c. c=(9/5)(f+32)
d. c=(9/5)(f-32)

B.  

Step-by-step explanation:

The given formula :

To convert this formula in terms of C , we first Subtract 32 on both sides , we get

Now multiply 5 on both the sides , we get

Divide both sides by 9 we get

OR

Therefore , the formula gives the conversion from degrees Fahrenheit to degrees Celsius will be :-

Hence, the correct answer : B.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet
