Answer:
A) she needs to earn $120 for her mouth piece
B) it will taker kaser 8 weeks to get enough money for the mouthpiece
Step-by-step explanation:
whats a segment tool? no idea but i can help solve this so you can attempt that part
explaining
so kaser needs $155, she already has $35 and gains $15 a week. i will be assisting you with how to solve for how much she has when she starts saving and how long until she saves it all
process A
155-35 = 120
answer A
she needs to earn $120 for her mouth piece
process B
120 divided by 15 = 8
answer B
it will taker kaser 8 weeks to get enough money for the mouthpiece
Answer:
B: 6
Step-by-step explanation:
Find the mean:
5+8+4+7= 24
24/4=6
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

The true expression of the variable x in the inequality expression given as |8x - 2| < 4 is -0.25 < x < 0.75
<h3>What are inequality expressions?</h3>
Inequality expressions are mathematical statements that are represented by variables, coefficients and operators where the opposite sides are not equal
<h3>How to determine the true expression of the variable x?</h3>
The inequality expression is given as
|8x - 2| < 4
Divide through the above equations by 2
So, we have the following inequality expression
|4x - 1| < 2
Remove the absolute value sign from the inequality expression
So, we have
-2 < 4x - 1 < 2
Add 1 to all sides of the above inequality expression
So, we have
-1 < 4x < 3
Divide through the above inequality expression by 4
So, we have
-0.25 < x < 0.75
Hence, the true expression of the variable x in the inequality expression given as |8x - 2| < 4 is -0.25 < x < 0.75
