One way to do this is use the fact that the exterior angles of all polygons add up to 360 degrees
So an exterior angle of a regular octagon = 360 / 8 = 45 degrees.
So each interior angle = 180 - 45 = 135 degrees
so total measure of all angles in octagon = 8 * 135 = 1080 degrees
The cost of 3 and 1/2 pounds of almond at the same rate is $26.60.
<h3>What is a fraction?</h3>
A fraction is simply a piece of a whole. The number is represented mathematically as a quotient where the numerator and denominator are split. In the illustration given as m/n, it should be noted that m is the numerator and n is the denominator.
Since the price for 7/8 of a pound of almonds is $6.65, the fraction per pound will be done by dividing the amount for a pound by 7/8.
= $6.65 ÷ 7/8
= $7.6
The cost of 3 and 1/2 pounds at the same rate is:
= 3 1/2 × $7.6
= $26.60
In conclusion, the cost is $26.60.

Answer:
95.45
Step-by-step explanation:
83% of 115 is 95.45
.83 × 115 = 95.45
if you wanted 83% of what is 115 then it would be 83% of 138.5542169 = 115
.83a = 115
115/.83 = a
115/.83 = 138.5542169
check:
.83 × 138.5542169 = 115

Answer:
5.5 liters
Step-by-step explanation:
1 milliliter equals to 1/1000 part of a liter, which is 0.001 liter.
1 milliliter = 1 * 0.001 liter
So if you have 5500 milliliters that means it equals to 5500 times one milliliters and 1 milliliter = 1 * 0.001 liter, so for 5500 milliliters it is 5500 times as much
5500 * 0.001
5500 * 1/1000
5500 / 1000
5.5 liters
As long as you know this number 0.001 , then it is easily to calculate between liters and milliliters.
EXTRA:
To convert from amount A which is given in a certain quantity, to another quantity, you sometimes have to multiply and in other cases you need to divide by a certain factor. The factor defines the relationship between the quantities.
Suppose you have 1000 times 1 milliliter then you can find the amount in liters by multiplying that number of milliliters times 0.001.
It is easy to see that
1000 * 1/1000
1000 / 1000
= 1 liter, but that is easy, because I choose an easy number for the amount of milliliters to convert into liters. But it works exactly the same for any amount!
