Answer:
Interior: 135 degrees
Exterior: 45 degrees
Step-by-step explanation:
The interior angle of a regular octagon is exactly 135 degrees, which can be found using the (n – 2)180 formula. The exterior is simply 180 - the interior, which is 45. :)
The sequence is an arithmetic sequence and the expression used to find the nth term would be 3n option fourth I and II is correct.
<h3>What is a sequence?</h3>
It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.
We have a sequence:
3, 6, 9, 12…
First term a = 3
Common difference d = 6 - 3 = 3
This is an arithmetic sequence.
nth term of the arithmetic sequence:
a(n) = 3 + (n-1)(3)
a(n) = 3n
Plug n = 5
a(5) = 3(5) = 15
Thus, the sequence is an arithmetic sequence and the expression used to find the nth term would be 3n option fourth I and II is correct.

Answer:
D) 180
Step-by-step explanation:
Keep in mind to properly use a percent you must set it to a decimal.
To do so simply move the . in 75. over to the left 2 times. Which will go to .75!
Now time to multiply 240 by .45.
240 x .45 =180
Before we solve anything, we need to know how many cups there are in a gallon.
There are 16 cups in 1 gallon.
We have 1.5 gallons.
There is a shortcut to finding the 0.5 extra gallons;
Divide the amount of cups per gallon by 2. This will give us an equivalent of 0.5 gallons.
16 / 2 = 8.
There are 8 cups per 0.5gal.
Now that we have our gallons translated into cups, let's sum up.
16 + 8 = 24.
There are 24 cups in 1.5 gallons.
The chef can get 24 1-cup servings out of the pot.
I hope this helps!
