If I was born in 1999 and 2019 how long has it been
stepladder [879]

Answer:

20 years

Step-by-step explanation:

2019-1999=20

Well it may not exactly be 20 years if you were born on October 7 1999 and it is January 1st 2019 then it would be 19 years. But assuming that it is the exact date then it would be 20 years. Also we are forgetting about leap days. If you were born on May 4th 1999 and it is May 3rd 2019 you are technically 20 years old. But I am not really sure if that really counts.

In the figure below, segment CD is parallel to segment EF and point H bisects segment DE :
Grace [21]

Answer:

See explanation

Step-by-step explanation:

In the figure below, segment CD is parallel to segment EF, DE is a transversal, then angles DIH and HGI are congruent as alternate interior angles when two parallel lines are cut by a transversal.

Consider triangles DIH and EGH. In these triangles,

  • \angle DIH\cong \angle EGH as alternate interior angles;
  • \angle DHI\cong \angle GHE as vertical angles;
  • DH\cong HE because point H bisects segment DE (given).

Thus,

\triangle DIH\cong \triangle EGH by AAS postulate

viva [34]
225/5 = 45
This means the parents gave her five dollars forty five times. If they gave her a five every time she saved one dollar, you just have to multiply the money she saved each time and the number of times she saved it, and you'll get the answer. 
Wendy saved $45 by herself
