Express the ratio of 3 ft to 18 in in lowest terms

1 answer:

5 0

In lowest terms this would be 2/1.
If you convert 3 ft to inches, you have 36 inches (3*12), giving you a ratio of 36/18. In lowest terms, this is 2/1.
Hope this helps!

Add up all.

Yards = 29 + 55 + 13 = 97

Feet = 2 + 1 + 1 = 4

Inches = 11 + 10 + 3 = 24

In conclusion your final anwser is

97 yd. 4 ft. 24 in.

Hope this helps!
Have a great day.

Part A

The angle of elevation of the staire case is given by

$Angle\ of\ elevation=\tan^{-1}{ \frac{Vertical\ rise}{landing} } \\ \\ =\tan^{-1}{ \frac{14}{20} }\approx35^o$

Part B:

If the landing of each step is changed to 17 inches and the elevation of each step to 21 inches, the new angle of elevation for the staircase is given by

 $Angle\ of\ elevation=\tan^{-1}{ \frac{Vertical\ rise}{landing} } \\ \\ =\tan^{-1}{ \frac{17}{21} }\approx39^o$
