The speed of light is about 300,000,000 meters per second. That's
about 3 * 10^8 meters per second. The speed of sound in dry air is
about 3 * 10^2 meters per second.
About how many times faster does light travel than sound in dry air?
Answer:
Light is about 299,999,700 mps (meters per second) faster than sound in dry air.
Step-by-step explanation:
We know that the speed of light is about 3 × 10 ^ 8 meters per second and that the speed of sound in dry air is about 3 × 10 ^ 2 meters per second. We need to solve 3 × 10 ^ 8 minus 3 × 10 ^ 2.
3 × 10 ^ 8 - 3 × 10 ^ 2 =
300,000,000 - 300 = 299,999,700
Light is about 299,999,700 mps (meters per second) faster than sound in dry air.

What percentage
of total hours was
spent jogging?
if you find the total hours for each sport i’ll give u brainlistttt paleeease
Answer:
40%
Step-by-step explanation:
So I mostly will focus on the jogging total hours because thats literally what it says lol. Anyways, here I used the percent equation, which is
___ is ___% of ___. Since the question is "what percent", we mark our blank percent part as x, and when I fill the equation in it will seem like this:
"20 is x% of 50 (total hours)". So, now I translate, and this means:
20=x50, or in other words, 20=50x. To get x alone we divide by 50, but we also do it for the 20. 20/50 is .4, but because it has to be a percent, we move the decimal 2 places to the right, which gives 40, and finally it becomes
40%.
Hope it helps
Answer:
40%
Step-by-step explanation:
(20 hours Jogging)/(50 hours Total) = 0.4
0.4 * 100 = 40

Can somebody explain why 8/17 is correct. Will make brainliest.
Answer:
8/17 is correct because cosine = adjacent/hypotenuse, and since angle A is theta, or the reference angle, the adjacent of A would be 8, and the hypotenuse is always across the right angle.
15/17 would be sine instead of cosine

Evaluate the expression if b= 6 and c= 10.
5b/c
Answer:
=3
Step-by-step explanation:
5b/c
=5*6/10
=30/10
=3
Answer:
If b = 6 and c = 10, the value of an expression is 3.
Step-by-step explanation:
Given the expression
[tex]\frac{5b}{c}[/tex]
We have to evaluate the expression if b = 6 and c = 10.
Important Tip:
In order to evaluate the expression [tex]\frac{5b}{c}[/tex], all we need to do is to substitute the value of b and c in the expression.
As the expression is
[tex]\frac{5b}{c}[/tex]
substitute b = 6 and c = 10 in the expression
[tex]\frac{5b}{c}=\frac{5\left(6\right)}{10}[/tex]
[tex]=\frac{30}{10}[/tex]
[tex]=3[/tex] ∵ [tex]\frac{30}{10}=3[/tex]
Therefore, if b = 6 and c = 10, the value of an expression is 3.
