Porter drove due East 20 miles on interstate 23, then due south 23 miles on interstate 77. To the nearest hundredth of a mile, how far was he from his starting point

The correct answer is 30 miles.

Step-by-step explanation:

Porter is driving due east to point, say B, from his initial point, say A, for about 20 miles. Therefore AB = 20 miles.

He is driving due south to point, say C, from B, for about 23 miles. Therefore BC = 23 miles.

Therefore the distance between A and C is given by the Pythagoras theorem,

⇒ AC = = = 30.479 miles ≈ 30 miles.

Therefore Porter is 30 miles away from his initial point, to the nearest hundredth of a mile.

answer: sorry

step-by-step explanation: can you tell me pls how to find the rational of two integers

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
