Light travels at a speed of about 3.0x10^8 meters per second. How far does light travel in 4,500 seconds You Would Get __ E __
light would travel approximately [tex]\( 1.35 \times 10^{12} \)[/tex] meters in 4,500 seconds.
To find out how far light travels in 4,500 seconds, we can use the formula:
[tex]\[ \text{Distance} = \text{Speed} \times \text{Time} \][/tex]
Given that the speed of light is approximately [tex]\( 3.0 \times 10^8 \)[/tex] meters per second and the time is 4,500 seconds, we can plug these values into the formula:
[tex]\[ \text{Distance} = 3.0 \times 10^8 \text{ m/s} \times 4,500 \text{ s} \][/tex]
Calculating this gives us:
[tex]\[ \text{Distance} = 1.35 \times 10^{12} \text{ meters} \][/tex]
So, light would travel approximately [tex]\( 1.35 \times 10^{12} \)[/tex] meters in 4,500 seconds.

Plot the x- and y-intercepts to graph the equation. y=13x−1 .
PLEASE plot it on a graph PLEASE and i will get you brainly and 15 points
Answer:
Given the equation: [tex]y = \frac{1}{3}x -1[/tex] .....[1]
To find the intercepts:
x-intercepts states that the graph cross the x-axis.
Substitute the value of y = 0 in [1] to solve for x;
[tex]0 = \frac{1}{3}x-1[/tex]
Add 1 to both sides we get;
[tex]1 = \frac{1}{3}x[/tex]
Multiply both sides by 3 we get;
[tex]3 = x[/tex]
x-intercepts = (3, 0)
y-intercepts states that the graph cross the y-axis
Substitute the value x = 0 in [1] to solve for y;
[tex]y = \frac{1}{3}(0) -1[/tex]
Simplify:
y = -1
y-intercept = (0, -1)
Now, using these x- and y--intercepts points to graph the given equation [tex]y = \frac{1}{3}x -1[/tex] as shown below.

Owen used these steps to solve the equation 4x+7=1+2(2x+3) . Which choice describes the meaning of his result, 7=7 ?
a.The result is not correct because Step 2 has an error.
b.The solution is x=7.
c.No values of x make the equation true.
d.All values of x make the equation true.
The choice that describes the meaning of the result is,
all values of x make the equation true.
The correct option is d.
What is an equation?Two algebraic expressions having same value and symbol '=' in between are called as an equation.
Given:
Owen used these steps to solve the equation,
4x+7 = 1+2(2x+3).
Simplifying,
4x + 7 = 1 + 4x + 6
4x + 7 = 4x + 6 + 1
4x + 7 = 4x + 7
Subtract 4x to both sides,
7 = 7.
That means, the equation has infinitely many solutions.
Therefore, all values of x make the equation true.

We have:
Two function f(x) and g(x) shown in the table.
From the table:
At x = -1

Prove the divisibility of the following numbers:
51^7-51^6 by 25
To prove the divisibility lets expand each number first to get the complete picture of the problem
51^7 = 8.974106779 . 10^11
51^6 = 1.75962878 . 10^10
(51^7 - 51^6) = 8.974106779 . 10^11 - 1.75962878 . 10^10
= 8.798143901. 10^11
[tex]\frac{8.798143901. 10^11}{25}[/tex]

Maggie and her friend visit a beach that has a shoreline 2 2/5 kilometers long. They walk along 2/3 of it. How many kilometers of the beach shoreline do they walk?
To find out how many kilometers of the beach shoreline Maggie and her friend walk, we need to multiply the length of the shoreline by the fraction they walk along. Maggie and her friend walk 8/5 kilometers of the beach shoreline.
Explanation:To find out how many kilometers of the beach shoreline Maggie and her friend walk, we need to multiply the length of the shoreline by the fraction they walk along.
First, we need to convert the mixed number 2 2/5 to an improper fraction. We can do this by multiplying the whole number (2) by the denominator (5) and adding the result to the numerator (2), then putting the new numerator over the denominator. So, 2 2/5 is equal to (2 * 5 + 2) / 5 = 12/5.
Next, we can multiply the length of the shoreline (2 2/5) by the fraction they walk along (2/3). Multiply the whole number and numerator separately, then add the products and put the result over the denominator.
So, (12/5) * (2/3) = (12 * 2) / (5 * 3) = 24/15 = 8/5.
Maggie and her friend walk 8/5 kilometers of the beach shoreline.
If you take a certain number 2.5 times then add 1.75 and divide the result by 0.8, you’ll get 37.5. What was the original number?
Answer:
The original number is 11.3
Step-by-step explanation:
Let the number is x and then we form the equation to solve it for the value of x.
1- Number is multiplied by 2.5 then it becomes = 2.5x
2- Then we add 1.75 to the expression then new expression will be = 2.5x + 1.75
3- We divide the result by 0.8 then expression will be = [tex]\frac{2.5x + 1.75}{0.8}[/tex]
4- Now the final expression is equal to 37.5 so the equation will be
[tex]\frac{2.5x + 1.75}{0.8}[/tex] = 37.5
Now we multiply 0.8 in both the sides of the equation
[tex]\frac{2.5x + 1.75}{0.8}[/tex]×0.8 = 37.5×0.8
2.5x + 1.75 = 30
2.5x = 30 - 1.75
2.5x = 28.25
x = 28.25/2.5 = 11.3
Answer:
11.3

the measure of an angle is 34 degrees what is the measure of its supplement
The measure of the supplement angle is 146 degrees.
What are supplementary angles?The supplementary angles is defined as when pair of angles addition to 180° then they are called as supplementary angles. There are two types of supplementary angles.
What are Adjacent angles?Adjacent angles is the type of supplementary angles. Adjacent angles have a common side and vertex, for example a corner point. Their points do not overlap in any way. In other terms, adjacent angles is pair of two angles next to each other
Given that the measure of an angle is 34 degrees
Let x = the measure of the supplement angle.
Two angles whose sum is 180 degrees are supplementary.
∴ x + 34 = 180
Then, (180 -34 ) is the supplement of that angle.
The measure of the supplement angle = 146 degrees
Hence, the measure of the supplement angle is 146 degrees.
