Light travels 3 x 10^5 kilometers in one second. How far does it travel in 6.7 seconds? Write your answer in scientific notation.
The distance covered by the traveling light in 6.7 seconds is 2.01 × 10⁶ kilometers.
What is the distance covered by the light in 6.7 seconds?The speed formula is expressed as:
Speed = Distance / Time
Given the parameter:
Distance covered by the light = 3 × 10⁵ kilometers
Elapsed time = 1 second
Speed =?
The speed of the light is:
Speed = Distance / Time
Speed = 3 × 10⁵ kilometers / 1 second
Speed = 3 × 10⁵ kilometers per second
Now, we find the distance covered by the light in 6.7 seconds.
Speed = Distance / Time
Distance = Speed × Time
Distance = 3 × 10⁵ kilometers per second × 6.7 seconds
Distance = 2.01 × 10⁶ kilometers.
Therefore, the distance traveled is 2.01 × 10⁶ kilometers.

A bamboo shoot is 20 inches tall at the zero and gross 24 inches each day which functions show below can be used to determine height F(n) of the bamboo after n days
It is given bamboo shoot is 20 inches tall when time is 0. It grows at the rate of 24 inches each day .
The y intercept b=20 and m= slope = 24.
Any equation can be written in the form y=mx+b where m is slope and b is y intercept.
The equation to determine height for n number of days can be written as
f(n)=24n+20
It can also be written as 24+the growth 1 day back or
F(n)=F(n-1)+24 where f(0)=20.
Among the given options equations 1 and 111 hold true
Option D is the right answer.

What is the volume of a rectangular prism with side lengths14.7 m, 23.4 m, and 3.2 m?
Help please ....zzzghg
Answer: [tex]f=168[/tex]
Step-by-step explanation:
In the picture, there is a multiplication problem of [tex]f=56\times3[/tex]
We can use distributive property in it so that the multiplication problem become easier.
Distributive property:-[tex](b+c)a=ba+ca[/tex]
In the product, the larger number is 56
Write [tex]56=50+6[/tex]
Now, [tex]f=56\times3\\\Rightarrow\ f=(50+6)3\\\Rightarrow\ f=(50)3+(6)3\\\Rightarrow\ f=150+18\\\Rightarrow\ f=168[/tex]

Heather was asked to graph 2x + 4y = 12 by using slope and y-intercept. Her graph is shown. Which choice supports the graph that she has drawn. A) The slope is positive 1 2 and the y-intercept is (0,3). B) The slope is negative 1 2 and the y-intercept is (0, 3). C) The slope is positive 1 2 and the y-intercept is (0, -3). D) The slope is negative 1 2 and the y-intercept is (0, -3).
Answer:
B) The slope is negative 1/2 and the y-intercept is (0, 3).
Step-by-step explanation:
First we rewrite the equation so we can easily find the slope and y-intercept. We do this by isolating the y-term:
2x+4y = 12
We want to subtract 2x from each side:
2x+4y-2x = 12-2x
4y = 12-2x
4y = -2x+12
Now we divide both sides by 4 (everything on both sides gets divided!):
4y/4 = -2x/4 + 12/4
y = -2/4x + 3
y = -1/2x + 3
The slope is -1/2 and the y-intercept is 3 (the point (0, 3)).
Her graph shows the y-intercept at (0, 3); this part is correct.
The graph also shows we go down one and over two between points; this is a slope of -1/2, which is correct.

We know that the area of a triangle is given by :-
[tex]\text{A}=\dfrac{1}{2}*b*h[/tex], where b is base and h is the height of the triangle.
From the given picture, it cam be seen that alll the traingles area of same measure, the base of the triangle = 2 inches
The height of the triangle = 6 inches
Now, the area of a triangle is given by :-

The price of a car has been reduced from $19,500 to $16,965. What is the percentage change of the price of the car?
Final answer:
The percentage change in the price of the car is a reduction of approximately 13%, calculated by taking the difference between the original and reduced prices, and then dividing by the original price and multiplying by 100.
Explanation:
To calculate the percentage change in the price of the car, you first find the difference in price and then divide it by the original price. Initially, the car was priced at $19,500 and then reduced to $16,965.
To find the difference, subtract the new price from the old price.
$19,500 - $16,965 = $2,535
Now, divide the difference by the original price and multiply by 100 to get the percentage.
($2,535 ÷ $19,500) × 100 = 13% (approximately)
The percentage change in the price of the car is a reduction of approximately 13%.

A model car has a windshield with dimensions 1/18 the size of a real car windshield. The rectangular windshield of the real car has an area of about 2318 sq in, with a width of 61 in. What are the side lengths of the model car's windshield? Round to the nearest hundredth?
Width of the model car's windshield is around 3.39 inches and the length is approximately 17.45 inches.
The area of the real car windshield is 2318 sq in, with a width of 61 in. The scale of the model car's windshield is 1/18 of the real car windshield.
To find the dimensions of the model car's windshield, first, calculate the area of the model windshield by dividing the real area by the square of the scale factor. Then, find the width and length of the model windshield by using the square root of the calculated area.
In this case, the width of the model car's windshield is around 3.39 inches and the length is approximately 17.45 inches.
Answer:
2.11 inches
Step-by-step explanation:
You want the side length of the windshield of a 1/18 scale model of a car with a 2318 in² windshield that has a width of 61 inches.
LengthThe side length of the actual windshield is found from ...
A = LW
L = A/W = (2318 in²)/(61 in) = 38 in
The length of the model windshield is 1/18 of this:
(38 in) × 1/18 = 2 1/9 in ≈ 2.11 in
The side lengths of the model car's windshield are 2.11 inches.
