129 arrangements can be made 5 x 4 x 3 x 2 x 1= 120
Answer:
2 and 23 are the factors of the composite number 46 .
Option (C) is correct.
Step-by-step explanation:
As given in the question 46 is a composite number .
Definition of factors
"Factors" are the numbers you multiply to get another number.
As 46 is written as
46 = 2 × 23
Therefore the factors of the composite numbers 46 are 2 and 23 .
The value of x when the richter scale rating scale is 8.4 is 251188643.151
<h3>What is a richter scale?</h3>
A richter scale is a numerical scale that is used for expressing the magnitude of an earthquake in a geographical area
<h3>How the richter scale works?</h3>
The richter scale takes the amplitude of the earthquake's largest seismic as an input and calculate (and display) the magnitude of an earthquake in the geographical area using a logarithmic function
<h3>How to determine the value of x?</h3>
The formula of a richter scale is expressed as:
log(x) = n
Where n represents the scale rating of the scale
In this case, n = 8.4.
So, we have:
log(x) = 8.4
Express as an exponent
x = 10^8.4
Evaluate the exponent
x = 251188643.151
Hence, the value of x when the richter scale rating scale is 8.4 is 251188643.151
