Problem Overview:
The task involves counting beats based on musical notes. The image provides a key for the number of beats each type of note represents:
-
Whole note (O): 4 beats
-
Half note (D): 2 beats
-
Quarter note (d): 1 beat
-
Eighth note (e): ½ beat
We need to calculate the total number of beats for each combination of notes given in the examples.

Solution:
#### Step-by-Step Calculations:
1.
a. O + O =
- Whole note (O) = 4 beats
- Whole note (O) = 4 beats
- Total: \( 4 + 4 = 8 \) beats
-
Answer: 8 beats
2.
b. D + O =
- Half note (D) = 2 beats
- Whole note (O) = 4 beats
- Total: \( 2 + 4 = 6 \) beats
-
Answer: 6 beats
3.
c. D + d =
- Half note (D) = 2 beats
- Quarter note (d) = 1 beat
- Total: \( 2 + 1 = 3 \) beats
-
Answer: 3 beats
4.
d. D + D =
- Half note (D) = 2 beats
- Half note (D) = 2 beats
- Total: \( 2 + 2 = 4 \) beats
-
Answer: 4 beats
5.
e. D + e =
- Half note (D) = 2 beats
- Eighth note (e) = ½ beat
- Total: \( 2 + 0.5 = 2.5 \) beats
-
Answer: 2.5 beats
6.
f. e + e =
- Eighth note (e) = ½ beat
- Eighth note (e) = ½ beat
- Total: \( 0.5 + 0.5 = 1 \) beat
-
Answer: 1 beat
7.
g. d + e =
- Quarter note (d) = 1 beat
- Eighth note (e) = ½ beat
- Total: \( 1 + 0.5 = 1.5 \) beats
-
Answer: 1.5 beats
8.
h. e + O =
- Eighth note (e) = ½ beat
- Whole note (O) = 4 beats
- Total: \( 0.5 + 4 = 4.5 \) beats
-
Answer: 4.5 beats
9.
i. O + O + D =
- Whole note (O) = 4 beats
- Whole note (O) = 4 beats
- Half note (D) = 2 beats
- Total: \( 4 + 4 + 2 = 10 \) beats
-
Answer: 10 beats
10.
j. D + D + d =
- Half note (D) = 2 beats
- Half note (D) = 2 beats
- Quarter note (d) = 1 beat
- Total: \( 2 + 2 + 1 = 5 \) beats
-
Answer: 5 beats
11.
k. O + D + d + e + e =
- Whole note (O) = 4 beats
- Half note (D) = 2 beats
- Quarter note (d) = 1 beat
- Eighth note (e) = ½ beat
- Eighth note (e) = ½ beat
- Total: \( 4 + 2 + 1 + 0.5 + 0.5 = 8 \) beats
-
Answer: 8 beats

Final Answers:
\[
\boxed{
\begin{aligned}
&\text{a. } 8 \text{ beats} \\
&\text{b. } 6 \text{ beats} \\
&\text{c. } 3 \text{ beats} \\
&\text{d. } 4 \text{ beats} \\
&\text{e. } 2.5 \text{ beats} \\
&\text{f. } 1 \text{ beat} \\
&\text{g. } 1.5 \text{ beats} \\
&\text{h. } 4.5 \text{ beats} \\
&\text{i. } 10 \text{ beats} \\
&\text{j. } 5 \text{ beats} \\
&\text{k. } 8 \text{ beats}
\end{aligned}
}
