Answer:
13/24
Step-by-step explanation:
First, it would be easier to find the common denominator of 1/3 and 1/8. The easiest way to do that is to do 3x8=24. This means the common denominator is 24 and so we must convert the fractions so they have this denominator.
1/3 --> 8/24
1/8 --> 3/24
Now, we can simply add these fractions together to find out the fraction of songs that are NOT country songs.
8/24 + 3/24 = 11/24 songs are not country songs.
To find out the fraction of songs that are country, simply do 1 (or 24/24) take away 11/24.
24/24 - 11/24 = 13/24 songs are country songs.
Answer:
Step-by-step explanation:
To prove Δ ABC similar to ΔDBE we can consider
Segments AC and DE are parallel.
⇒ DE intersects AB and BC in same ratio.
AB is a transversal line passing AC and DE.
⇒∠BAC=∠BDE [corresponding angles]
Angle B is congruent to itself due to the reflexive property.
All of them are telling a relation of parts of ΔABC to ΔDBE.
The only option which is not used to prove that ΔABC is similar to ΔDBE is the first option ,"The sum of angles A and B are supplementary to angle C".
