The value of [b] if a = 1/8 and c = 4 will be 33/16.
What is the mean of two numbers?
The mean of two numbers [a] and [b] is -
[M] = (a + b)/2
Given is that a = 1/8 and c = 4.
We have the following values -
a = 1/8
c = 4
Therefore, we can write the value of [b] as -
b= (1/8 + 4)/2
b = (33/8)/2
b = 33/8 x 1/2
b = 33/16
Therefore, the value of [b] if a = 1/8 and c = 4 will be 33/16.

A pyramid of logs has 2 logs in the top row, 4 logs in the second row from the top, 6 logs in the third row from the top, and so on, until there are 200 logs in the bottom row. Is the pattern an arithmetic sequence? Identify a and d. Write the 50th term of the sequence. Find the total number of logs in the first 10 rows.
Answers
Answer:
1) Is the pattern an arithmetic sequence?
Yes it is
2)Identify a and d.
a = First term = 2
d = Common difference = 2
3) Write the 50th term of the sequence.
50th term = 100
4) Find the total number of logs in the first 10 rows.
= 1010 logs
Step-by-step explanation:
Is the pattern an arithmetic sequence?
Yes it is
2) Identify a and d.
A pyramid of logs has 2 logs in the top row, 4 logs in the second row from the top, 6 logs in the third row from the top, and so on,
The formula for arithmetic sequence =
an = a+ (n - 1)d
a = First term
d = Common difference
For the above question:
a = 2
d = Second term - First term
= 4 - 2
d = 2
3) Write the 50th term of the sequence.
Using the formula for arithmetic sequence
an = a+ (n - 1)d
a = 2
n = 50
d = 2
a50 = 2 + (50 - 1)2
= 2 + (49)2
= 2 + 98
= 100
The 50th term = 100
4)Find the total number of logs in the first 10 rows.
Sum of first n terms = n/2(a + l)
n = 10
a = first term = 2
We are told that there are 200 logs in the bottom row, hence:
l = last term = 200 logs
Hence,
Sn = 10/2×[ (2 + 200
= 5(202)
= 1010 logs
Garvin bought skis that cost $500 at the new store opening. The store gave him 60 days free credit. However, if he does not pay within 60 days they will charge him a 12 percent annual interest rate. How much interest will Garvin pay if he lets the account go for 90 days.
Answers
If Garvin lets the account go for 90 days, he will pay approximately $4.11 in interest.
If Garvin lets the account go for 90 days, he will exceed the 60-day free credit period by 30 days. This means he will be charged interest on the outstanding balance for those 30 days.
Since there is no information provided regarding any payments or partial payments made by Garvin within the 60-day period, we can assume that the full $500 is still outstanding.
Using the formula for simple interest:
Interest = Principal x Rate x Time
Principal = $500
Rate = 12% per year = 0.12
Time = 30 days / 365 days (since the rate is an annual rate)
Interest = $500 x 0.12 x (30/365) = $4.11 (rounded to two decimal places)
Therefore, if Garvin lets the account go for 90 days, he will pay approximately $4.11 in interest.

What is an equation of the line that passes through the point (5,-5) and is parallel to the line x+5y=20
Answers
Answer:
y = [tex]-\frac{1}{5}[/tex]x - 4
Step-by-step explanation:
Given parameters:
Coordinates = (5, -5)
Equation of the line, x + 5y = 20
Unknown:
Equation of the line parallel to this= ?
Solution:
To find the equation of the line, we must first understand that parallel lines are lines having the same slope. They do not cross each other at any point.
The equation of any straight line is given as;
y = mx + c
y and x are the coordinates
m is the slope
c is the y- intercept
Now,
x + 5y = 20
Let us find the slope of this line;
5y = -x + 20
Divide through by 5;
y = [tex]-\frac{1}{5}[/tex]x + 4
The slope of the new line is the coefficient of x;
Slope = [tex]-\frac{1}{5}[/tex]
So, let us find the y-intercept of the new line;
-5 = [tex]-\frac{1}{5}[/tex] x 5 + c
-5 = -1 + c
c = -5 + 1 = -4
Now,
y = [tex]-\frac{1}{5}[/tex]x - 4
Answer: y = -(1/5)x - 4

How do I turn something like this: 3x - 2y = -16

(Whoever can explain gets Brainliest) (UwU)
Answers
[tex]3x - 2y = - 16[/tex]
Subtract sides -3x
[tex]3x - 3x - 2y = - 3x - 16[/tex]
Simplification
[tex] - 2y = - 3x - 16[/tex]
Negatives simplifies
[tex]2y = 3x + 16[/tex]
Divided sides by 2
[tex] \frac{2y}{2} = \frac{3x + 16}{2} \\ [/tex]
[tex] \frac{2}{2}y = \frac{3}{2}x + \frac{16}{2} \\ [/tex]
Simplification
[tex]y = \frac{3}{2}x + 8 \\ [/tex]
This is the slope-intercept form.

Rena’s grandfather opened a savings account as a college fund for her. His initial deposit and the yearly simple interest rate are shown.
A college graduate is shown walking up stairs. The bottom step represents three thousand five hundred dollars. The value of the top step is unknown. The distance up the stairs is labeled four years. The simple interest rate is three point two five percent.
How much will Rena have in this account after 4 years?
Enter the correct answer in the box.
Answers
Answer:
Total amount (A) = $3,955
Step-by-step explanation:
Given:
Initial deposit (P) = $3,500
Rate of interest (r) = 3.25%
Number of years (t) = 4
Find:
Total amount (A)
Computation:
Simple interest = (p)(r)(t)
Simple interest = (3,500)(3.25)(4)
Simple Interest = $455
Total amount (A) = Initial deposit (P) + Simple Interest
Total amount (A) = 3,500 + 455
Total amount (A) = $3,955

Write a system of linear equations that has (-4, 8) as the solution. Once you have made your system of equations, solve it algebraically to show that you do indeed get the solution (-4, 8).
Answers
Answer:
See below
Step-by-step explanation:
(-4, 8) has to be the solution.
1st equation: -4x+8y = 1
2nd equation: 8x - 4y = 1
These should work. Do the matrix-substitution combo method to see:
-4 8 1
.8 -4 -1
Reduce and and matrix-substitution combo:
1 0 -4
0 1 8
The reduced eckerd form of the matrix shows that the solutions are (-4, 8)
Therefore it -4x + 8u = 1 and 8x - 4y = 1 are the two equations for the system.
