Answer:
I'm a few years late, lol, but um the answer is 42 x [tex]10^{-3}[/tex] meters
For all the people who still need the answer.
Step-by-step explanation:
5 x [tex]10^{-11}[/tex] and 8.4 x [tex]10^{8}[/tex]
5 x 8.4 = 42 (multiply like terms)
[tex]10^{-11}[/tex] + [tex]10^{8}[/tex] = [tex]10^{-3}[/tex] (add the exponents)
42 x [tex]10^{-3}[/tex]
The length in scientific notation is [tex]42\times10^{-7[/tex] meter.
What is scientific notation?Scientific notation is a method for expressing a given quantity as a number having significant digits necessary for a specified degree of accuracy, multiplied by 10 to the appropriate power such as [tex]1.56\times10^7[/tex].
Given that, the diameter of a hydrogen atom is about [tex]5\times10^{-15}[/tex] meter. Suppose 8.4×10⁸ hydrogen atoms were arranged side by side in a straight line.
Now, multiply the numbers
[tex]5\times10^{-15}[/tex]×8.4×10⁸
= [tex]42\times10^{-7[/tex] meter
Therefore, the length in scientific notation is [tex]42\times10^{-7[/tex] meter.

The simplified expression is 60mn⁶.
What is factorization?Factorization is a process to simplify the expression by finding the factors of that expression.
And to find the same expression from factors, you have to reverse the process.
Given that the expression is 6√1,000m³n¹².
We can simplify this expression by breaking down 1,000 into its prime factorization:
1,000 = 2³ x 5³
Then we can rewrite the expression as:
6√(2³ x 5³ x m³ x n¹²)
Using the properties of radicals, we can separate the factors inside the radical:
6√2³ x √5³ x √m³ x √n¹²
Simplifying each square root term:
6 x 2 x 5 x m x n⁶
= 60mn⁶

A photo that is 4 in wide and 6 in high is enlarged to a poster that is 3ft wide and 4 1/2 ft high what is the ratio of the width of the photo to the width of the poster
Answer:
Required ratio in the simplest form = 1 : 9
Step-by-step explanation:
Width of photo = 4 inches
Height of the photo = 6 inches
Width of the poster = 3 feet
Now, 1 feet = 12 inches
So, Width of the poster = 3 × 12 = 36 inches
Height of the poster = 4.5 feet
= 54 inches
We need to find the ratio of the width of the photo to the width of the poster
⇒ Required Ratio = 4 : 36
⇒ Required ratio in the simplest form = 1 : 9

Luca and William are playing a video game and they have scored a total of 20,000 points. Luca scored 4,000 more points than William. If you let l= the number of points that Luca scored, and w= the number of points that William scored, then the problem can be represented by the system:
l+w=20,000 and l=w+4,000
Graph the system. How many points did each boy score?
My possible answers are:
a. William = 8,000 and Luca = 12,000
b. William = 12,000 and Luca = 8,000
d. William = 4,000 and Luca = 16,000
l+w=20000
l=w+4000
w+4000+w=20000
2w+4000=20000
2w=16000
w=8000
l = 8000 +4000 = 12000

When two balanced dice are rolled, there are 36 possible outcomes. To find the probability that the sum of the numbers on the dice is 6 or 10, count the favorable outcomes and divide it by the total outcomes.
Explanation:When two balanced dice are rolled, there are 36 possible outcomes. To find the probability that the sum of the numbers on the dice is 6 or 10, we need to count the favorable outcomes and divide it by the total outcomes.
For the sum of 6, there are 5 possible outcomes: (1,5), (2,4), (3,3), (4,2), (5,1). For the sum of 10, there are 3 possible outcomes: (4,6), (5,5), (6,4). Therefore, there are 8 favorable outcomes out of 36 total outcomes.
The probability is calculated as:
Probability = Favorable outcomes / Total outcomes = 8 / 36 = 2 / 9

The value of a treadmill bought new for $1000 decreases 5% each year. Use a graph to predict the value of the treadmill in 5 years.
A) ≈ $773.78
B) ≈ $857.38
C) ≈ $902.50
D) ≈ $814.50
The predicted value of the treadmill after 5 years, with an annual depreciation rate of 5%, is approximately $773.78. This calculation uses the exponential decay formula and corresponds to option A).
To predict the value of a treadmill in 5 years that was bought new for $1000 and decreases 5% each year, we can use the formula for exponential decay:
V = [tex]P(1 - r)^t[/tex]
Where:
V is the future value of the treadmill,
P is the original value ($1000),
r is the rate of decay (5% or 0.05), and
t is the time in years (5 years).
By substituting the values we have:
V = $1000(1 - 0.05)⁵
V = $1000(0.95)⁵
V = $1000(0.77378) = $773.78
Therefore, the predicted value of the treadmill after 5 years is approximately $773.78, which corresponds to option A).

Answer:
Company 2 because it is gaining six times the number of employees, while Company 1 is only adding 6 employees every year.
Step-by-step explanation:
Looking at the table, the number of employees in Company 1 goes up by 6 employees per year.
The number of employees in Company 2 is multiplied by 6 every year; this means they gain more employees after the first year than Company 2 does (they go from 6 to 36, which is a gain of 30, while Company 1 goes from 6 to 12, a gain of 6).
If we are looking strictly at the number of employees, Company 2 is the better choice.
