Point A is the begining of the line on the left its elevation is in the chart above. Point B is the end of the line on the roght its elevation is in the chart above. Using mathematical interpolation calculate the distance from Point A for each full foot elevation in the chart below. give answer to tenths of inch.

i need help with the rest i goy some started already

@jim_thompson5910

8. jim_thompson5910

did you see how to get 4.8 for the first line?

9. krissywatts

yes

10. krissywatts

the rest seem to be off by a few numbers so idk if im right

11. jim_thompson5910

If not, then you basically have this triangle |dw:1353120334241:dw|

12. jim_thompson5910

and you solve for x 6/x = 0.5/0.4 6*0.4 = 0.5x 2.4 = 0.5x 2.4/0.5 = x x = 4.8

13. jim_thompson5910

for the second line, you're going to have |dw:1353120446761:dw|

14. jim_thompson5910

so 4.1/0.4= 3.5/x 4.1x = 0.4*3.5 4.1x = 1.4 x = 1.4/4.1 x = 0.34146 x = 0.3 (round to the nearest tenths place)

15. jim_thompson5910

for line 3, you're going to have |dw:1353120667399:dw|

16. krissywatts

.oh okay so roun to nearest tenth of an inch

17. krissywatts

i forgot to read that part sorry

18. jim_thompson5910

4.1/0.4= 3.5/x 4.1x = 1.4*3.5 4.1x = 4.9 x = 4.9/4.1 x = 1.19512 x = 1.2 (round to the nearest tenths place)

19. jim_thompson5910

yeah so it looks like you have it pretty much
