Explanation:
We have n = 8 sides for this octagon.
This means the interior angles sum to 180(n-2) = 180(8-2) = 180*6 = 1080 degrees.
The tickmarks tell us that each side is the same length, so we have a regular octagon. This means that all 8 angles are the same measure. Let's say each angle is y degrees.
1 angle = y degrees
8 angles = 8y degrees
Solving 8y = 1080 leads to y = 1080/8 = 135
Each angle of this regular octagon is 135 degrees.
--------------------
Now set 16x+23 equal to 135 and solve for x
16x+23 = 135
16x+23-23 = 135-23
16x = 112
16x/16 = 112/16
x = 7

Isabel is designing a new fish tank that is shaped like a triangular prism with lateral faces made of glass. The bases of the prism are right triangles. Isabel’s new fish tank will look like the diagram below but it will have twice the height of the prism shown in the diagram.
Help?
Answers
The lateral surface area of Isabel's fish tank is 384 inches².
The lateral surface area is the sum of the area of the other faces of the figure excluding the bases.
Isabella fish tank is twice the height of the prism . Therefore
h = 2(8) = 16 inches
The sum of the area of the other three sides are as follows:
Lateral surface area = 16(6) + 16(8) + 16(10)
Lateral surface area = 96 + 128 + 160
Lateral surface area = 384 inches²

Chase invested $39,000 in an account paying an interest rate of 3.2% compounded
daily. Assuming no deposits or withdrawals are made, how long would it take, to the
nearest tenth of a year, for the value of the account to reach $66,100?
Answers
Answer:
16.5
Step-by-step explanation:
It takes 0.05 years account to reach $66,100
What Is an Interest Rate?The interest rate is the amount a lender charges a borrower and is a percentage of the principal—the amount loaned. The interest rate on a loan is typically noted on an annual basis known as the annual percentage rate (APR).
According to the question, we have
Principal = 39000
Interest rate = 3.2%
The investment compounds daily.
So we can get F = [tex]39000(1+0.032)^{x}[/tex]
When F = 66100
[tex]66100=39000(1+0.032)^{x}[/tex]
⇒ [tex]\frac{66100}{39000}=(1+0.032)^{x}[/tex]
⇒ [tex]1.69=(1.032)^{x}[/tex]
⇒ [tex]x = log 1.69_{1.032}[/tex]
⇒ [tex]x = \frac{log1.69}{log1.032}[/tex]
⇒ x = 17 days
It takes 17 days account to reach $66,100
Converting days into years
= [tex]\frac{17}{365}[/tex]
= 0.045
= 0.05 (nearest tenth of a year)
Hence, It takes 0.05 years account to reach $66,100.
