x = -8/5 or x = 8/5
Sum of the first ten terms where all terms are positive = 4092
========================================================
Explanation:
r = common ratio
first term = 4second term = (first term)*(common ratio) = 4rthird term = (second term)*(common ratio) = (4r)*r = 4r^2The first three terms are: 4, 4r, 4r^2
We're given that the sequence is: 4, 5x, 16
Therefore, we have these two equations
5x = 4r4r^2 = 16Solve the second equation for r and you should find that r = -2 or r = 2 are the only possible solutions. If r = -2, then 5x = 4r solves to x = -8/5. If r = 2, then 5x = 4r solves to x = 8/5.
-----------------
To find the sum of the first n terms, we use this geometric series formula
Sn = a*(1 - r^n)/(1 - r)
We have
a = 4 = first termr = 2, since we want all the terms to be positiven = 10 = number of terms to sum upSo,
Sn = a*(1 - r^n)/(1 - r)
S10 = 4*(1 - 2^10)/(1 - 2)
S10 = 4*(1 - 1024)/(-1)
S10 = 4*(-1023)/(-1)
S10 = 4092

$600 at 4% for 9 months.
The simple interest for the principal amount of $600 at the rate of 4% for 9 months will be equal to $216.
What is Simple interest?A quick and simple way to figure out interest on that money is to use the simple interest approach, which adds interest at the same rate for each daily cycle, and it is to the initial principal amount. A way to figure out how much interest will be charged on an amount of money at a specific rate and for a specific duration of time is by using simple interest.
As per the given information in the question,
Principle amount, P = $600
Time, T = 9 months
Rate, R = 4%
SI = (600 × 9 × 4)/100
SI = $216.
The SI will be $216.

Matt has 5 Cookies
Linn eats 3 of the cookies
How old is Linn
Answer:
3
Step-by-step explanation:
Where did you get this question?
The number of cookies left, if Matt has 5 Cookies and Linn eats 3 of the cookies, is 2.
What is subtraction?The action of subtracting a matrix, vector, or other quantity from another according to predetermined rules in order to find the difference.
Given:
The total number of cookies, t = 5,
The number of cookies Linn eats, n = 3,
Calculate the number of cookies left by using subtraction as shown below,
The number of left cookies = Total number of cookies - The number of cookies Linn eats
The number of left cookies = t - n
The number of left cookies = 5 - 3
The number of left cookies = 2
Thus, the number of cookies left is 2.

The value of x in the circle is 13.
Option C is the correct answer.
What is a circle?A circle is a two dimensional figure with a radius and circumference of 2pir.
The area of a circle is πr².
We have,
A chord is a line segment connecting two points on a circle.
A chord is different from a diameter, which is a chord that passes through the center of the circle.
The chords in a circle are all the same with the same length.
From the given diagram,
There are two chords.
This can be written as:
(15 + 8) = 23 makes one chord.
(10 + x) makes one chord.
Now,
23 = 10 + x
Solve for x.
23 = 10 + x
23 - 10 = x
x = 13
Thus,
The value of x in the circle is 13.

The radius of a circle is 12 in. Find its circumference in terms of
π
π.
Answer:
It would be 24(π)
Step-by-step explanation:
This is due to the circumfenrece equation for a circle being (π)D, with D as the diameter which is 2x the radius, so 12x2=24.
After this, it is 24(π), though leave it at there since it is meant to be written in terms of it. You're now done!

The formula for the perimeter, P, of a rectangle is P = 2(l + w), where l represents the length and w represents the width.
A. Todd has a string that is 26 inches long and wants to create a 9-inch-long rectangle with it. Substitute these values into the formula above, and solve for w to determine how wide Todd’s rectangle must be. Show your work.
B. Todd solved for the width arithmetically, as follows:
The length of the rectangle is 9 inches, so the sum of the lengths of the two long sides is 2 • 9 = 18 inches.
The string is 26 inches long, and 18 inches are used for the long sides of the rectangle, so the number of inches available for the short sides is 26 − 18 = 8 inches.
A rectangle has 2 congruent short sides, so the length of each short side, or the width of the rectangle, is 8 ÷ 2 = 4 inches.
Describe how Todd’s arithmetic solution process is similar to your algebraic solution process from part A, and how they are different.
C. The perimeter formula can be solved for w, in terms of P and l, as shown below.
P = 2(l + w)
P = 2l + 2w
P − 2l = 2w
= w
Explain why it could be useful to solve the perimeter equation for w in terms of P and l.
Answer:
p= 2L + 2w
p= 2×26 + 2×9
35-52=18
w=35

Subtract 16 on both sides and you should get:
9 = 3x
Divide both sides by 3
9/3 = 3x/3
