How many eighth notes are in each rhythm

The first measure has 2 quarter notes, and each one gets one count. You can count them as "one two." The second measure has 4 eighth notes, written as pairs with their tails connected.

Step-by-step explanation:

How many 8th notes are in each beat?

The first place to start with subdivisions of the beat is learning to feel the eighth note subdivision. Most music is in 4/4 time (see time signatures). That means 4 beats per bar/measure and each beat equals 1 quarter note. If we divide each of those quarter note beats in half, we get 8 eighth notes.

Step-by-step explanation:

rectangle: 9 1/8 x 4 1/9 = 37 37/72in

parallelogram: b times h= 10.3 x 6.2 = 63.86

trapezoid: a+b/2 times h= 42.5

volume of prism: l times w times h= 36
