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:

1.9657⋅10^4

Expanded Form:

19657

Step-by-step explanation:

the bold ones are the answers

Answer:

19657

Step-by-step explanation:

Exponentiation: 10 ^ 4 = 10000

Multiple: 2 * the result of step No. 1 = 2 * 10000 = 20000

Exponentiation: 7 ^ 3 = 343

Subtract: the result of step No. 2 - the result of step No. 3 = 20000 - 343 = 19657      

I am pretty sure this is correct

Answer:

y = 7x - 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 7 and c = - 5, then

y = 7x - 5 ← equation of line

Answer:

∠ P = 40°

Step-by-step explanation:

Since PQ = PR then the triangle is isosceles and the base angles are congruent, then

∠ R = ∠ Q = 70° , so

∠ P = 180° - (70 + 70)° ← sum of angles in triangle is 180°

∠ P = 180° - 140° = 40°

Answer:

The answer would be $37.40

Step-by-step explanation:

The sale price would be the current price which is 44 - 15% of itself.

It is 15 percent off, so 44 x 0.85 would be the equation, since the now price is 85 percent of the original price.

44 x 0.85 = 37.40

Answer:

4 ( x + 4 )

Step-by-step explanation:

Answer:

x = ±9

Step-by-step explanation:

x² - 55 = 26

   +55   + 55

     x² = 81

     x = √81

     x = ± 9

Answer:

x = 9, -9

Step-by-step explanation:

x^2 - 55 = 26

x^2 = 81.

Now, you might think that x = 9, but don't be fooled. -9 squared is also equal to 81.

So, x = 9, -9

The speed of the flying arrow will be 9 meters/second.

Speed describes how accelerated something or somebody is moving. If you know the distance traveled and the time it took, we can calculate the average speed of an object.

The speed formula is speed = distance/time.

We are given that Cupid's arrow travels 45 meters in 5 seconds.

Therefore, distance = 45 meters

Time=  5 seconds.

Thus, speed = distance/time

Speed = 45/5

Speed  =9

Integer is a subset of Real Number. It can be broken into these following:

Integer can be any whole numbers. Keep in mind that Integers cannot be fractions, decimal, approximate value, etc. Integers can only be something like 1,2,3,-1,-2,0.

Integers are like Natural or Counting Numbers except they have 0 and negative numbers.

Positive Integers are basically a natural or counting number. It starts from 1 to any positive countable infinity. Here is the example of positive integer: 1,2,3,4,5,6,7,...

Zero is just a number 0. It is between the negative and positive. 0 is neither positive or negative but it is categorized as Zero.

Negative Integers are opposite of Positive Integers. The opposite of plus is minus and the opposite of minus is plus. Negative Integers are less than both 0 and Positive Integers. Here is the example: -1,-2,-3,-4,-5,...

Integers are whole numbers with a positive or negative counterparts.

If that doesn't make sense let me make some examples

-4, 100, 9300 would be integers. Using my definition they all have negative or positive counterparts.

-2.3, 7.8888(etc.) 2/3 would not be integers. Even though -2.3 and 7.8888(etc.) have negative/ positive counterparts they are not whole numbers.

Hope that helped!

Graph is a way to represent a lot of data in a visual formal. The graph that best represents the student's walk is graph A.

A graph is a way to represent a lot of data in such a visual formal that it is easy for the user to understand the complete information in one go. Usually, the line of the graph is a function that follows the graph.

As we can see that the y-axis of the graph represents the distance traveled by the student while, the time taken by the student to cover the distance is given on the x-axis.

We know that the rate of 1.5 meters per second, means that the student will cover the 1.5 meters in 1 second, therefore, the line will be a slope that will represent the walk of the student. At time t=4 seconds, a student stopped for 4 seconds therefore, the time will increase but the distance will be constant for the student, therefore, the situation will be represented by a horizontal line.

Hence, the graph that best represents the student's walk is graph A.
