To find the length of the envelope, we can multiply the height of the envelope by the factor that gives the length in relation to the height.
Given:
- Height of the envelope = 3 inches
- Length is given as 4 9/10 times the height
First, we convert 4 9/10 to an improper fraction:
\[
4 \frac{9}{10} = \frac{40}{10} + \frac{9}{10} = \frac{49}{10}
\]
Now we can calculate the length of the envelope:
\[
\text{Length} = \text{Height} \times \text{Factor}
\]
We substitute the values:
\[
\text{Length} = 3 \times \frac{49}{10}
\]
We convert 3 to a fraction:
\[
3 = \frac{30}{10}
\]
Now we can multiply the fractions:
\[
\text{Length} = \frac{30}{10} \times \frac{49}{10} = \frac{30 \times 49}{10 \times 10} = \frac{1470}{100}
\]
Next, we simplify \(\frac{1470}{100}\):
Both the numerator and denominator can be divided by 10:
\[
\frac{1470 \div 10}{100 \div 10} = \frac{147}{10}
\]
We can convert this improper fraction into a mixed number:
\[
\frac{147}{10} = 14 \frac{7}{10}
\]
So, the length of Connor's envelope is:
\[
\boxed{14 \frac{7}{10}} \text{ inches}
\]
