## Taisha_Casseus 3 years ago Convert 38degrees F to degrees celsius. If necessary, round your answer to the nearest tenth of a degree. Here are the formulas. C=5/9(F-32) F=9/5 C+32

1. amistre64

what is 38-32?

2. Taisha_Casseus

6

3. liliy

plug in the f which is 38 . intot he first equation:

4. amistre64

good, and 6*5?

5. amistre64

liliy has a typo

6. liliy

ooopppss! thanks

7. liliy

5/9(38-32)

8. Taisha_Casseus

30

9. amistre64

good, and the last part is 30/9 = C; whats 30/9?

10. Taisha_Casseus

3.3

11. amistre64

ill trust you on that one

12. Taisha_Casseus

lol so the answer is ? 3.3?

13. amistre64

yep

14. Taisha_Casseus

Omg! that was easy, Thank yu

15. amistre64

yw :)

16. Taisha_Casseus

Whats 17.7 rounded to the nearest tenth of a degree?

17. liliy

.7 is the tenth

18. Taisha_Casseus

19. liliy

no , u keep it the decimal . a TENTH is 1/10 of a number. so its the first place after the decimal...

20. Taisha_Casseus

21. liliy

the number 17.7 : the 1 is the tens place, 7 is hte ones place, .7 is the TENTHS place. so when it asks for the tenth place, it wants the number up until that place: which owuld be 17.7

22. Taisha_Casseus

Okay Thank you.. But I just put that in and it says its wrong

23. liliy

hmmmm.... does it want hte TENs or TENTHs place?

24. Taisha_Casseus

the tenths place

25. liliy

that is strange. where are you putting this into?

26. Taisha_Casseus

a math program for my math class

27. liliy

well the number after the decimal is the tenths place.

28. Taisha_Casseus

yes, aren't you suppose to round up because the number is 7?

29. liliy

but you round to that number.. wats the number after the 7?

30. Taisha_Casseus

its alot of 7's after

31. liliy

oh, well then yes, you round up. so your answer should be 17.8

32. Taisha_Casseus

Nope its wrong...but thank yu anyway...

33. liliy

oh. well thats awkward. lol sorry

34. Taisha_Casseus

lOl it said the answer was 147.2

35. liliy

thats not even possible. F is always a bigger number than C. if F is 38, C is gonna be really small....

36. Taisha_Casseus

Thats wat Im saying, idk... but this is how it has the formula f=9/5c+32 =9/5(64)+32 =147.2

37. liliy

where did it get 64 from????

38. Taisha_Casseus

i had to convert 64 degrees C to degrees F

39. liliy

oy vey.

40. Taisha_Casseus

Idk ma...

41. Taisha_Casseus

But (64)+32 = 96 so I dn't get it

42. liliy

but u need to multiply by 9/5

43. Taisha_Casseus

but that gives me 172.8 or did i do it wrong?

44. liliy

u did it wrong.... it shoudl be 147.2

45. Taisha_Casseus

you are right...my bad! I got it now i have to use a scientific calculator

46. Taisha_Casseus

thank yu btw....

47. liliy
