Marco walked 27/100 kilometers to the park. Then he walked 1/10 kilometer to the library. What fraction of a kilometer did he walk in all?

37/100

Step-by-step explanation:

The fraction of a kilometer that he walked in all would be the sum of 27/100 and 1/10.

To add them, first find the lowest common multiple of both denominators. This number is 100 so will be the denominator.

Divide 100 by each denominator and multiply it by the numerator:

= (27 + 10) / 100

= 37/100

Note: 100/10 = 10

= 10 * 1 = 10 which is the second numerator.

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
