Enter a decimal rounded to the hundredths place.
miles

Answer 1

11) if it has a perimeter of 22m and one side is 6m the mult. 6mX2 (both side of room) then subtract that # from 22 = 10. then divide 10 by 2. it width is 5m. 5m+5m+6m+6m=22m

12) 350mi/7hr= 50mph

13) 1435mi/5hr= 287mph

14) if F = (9/5)(C) + 32 than F/(9/5)-32=C
C= 59/(9/5)-32
C= 5(59*-32*)/9
C=15*

15) if the walker goes 6mph then after 2 hrs he has gone 12miles. the jogger is 8miles ahead after 2 miles so you know he has gone 20miles total (12mi+8mi) in the 2 hrs. therefore the jogger is moving 10mph

16) she invests 1000 in the bond. 1000x.05= 50
17) she invests 1500 in the stock. 1500x.03=45

im too lazy to do the rest but i hope this helps........ if your really stuck on them let me know and i can help you. i just dont feel like typing anymore. good luck
