Mathematics

4 0

Answer:

1.0014 Miles

Step-by-step explanation:

The light travels at 186,291 miles per second (~300,000 km/s), and speed of sound in dry air is equal to 0.21 - 0.22 miles per second (0.33-0.35 km/s), as it varies with the temperature. We can notice the lightning almost immediately even though the storm is far from us, but the thunder needs around 5 seconds to travel one mile and approximately 3 seconds to travel one kilometer. Thanks to this seven orders of magnitude difference in sound and light propagation, we can easily estimate the storm distance

5. At a classroom costume party,
Alenkasestr [34]

The required simplified value of b + g is 21.


Given that,

At a classroom costume party, the average age of the b-boys is g, and the average age of the g girls is b.
The average age of everyone at the party (all these boys and girls, plus their 42- year-old teacher) is b+g,

<h3>What is average?</h3>

The average of the values is the ratio of the total sum of values to the number of values.

Here,

The average age of the b-boys is g.
The average age of the g-girls is b.
The average age of everyone at the party (all these boys and girls, plus their 42-year-old teacher) is b+g,

Now,
average of  n = 3 (b , g , b+g)
Average =  g + b + 42 / 3
b + g = (b + g + 42 ) / 3
3b + 3g = b + g +  42
3b - b + 3g - g = 42
2b + 2g = 42
2 (b + g) = 42
b + g = 21

Thus, the required simplified value of b + g is 21.
