Answer:
sum_of_interior_angles = (number_of_sides - 2) x 180° → if number_of_sides is 21: sum = (21 - 2) x 180° = 19 x 180° = 3420°
Step-by-step explanation:
1/2 and you can also say 4/8 which simplifies down to 1/2 and so does 2/4.
First, let's find the number of lunches:
14*3 = 42
To find how many lunches have ham sandwiches, we multiply the total number of sandwiches by the percentage of the ham sandwiches:
0.55 * 42
Multiply:
23.1
We can round down:
There are about 23 lunches with ham sandwiches
It's not possible for a number to not have any prime factors be cause the number will always be able to have the factor of 1 whcih is a prime number
1/10÷2/3=KCF (keep,change,flip)
1/10×3/2=3/20 cups
0.15=15%=3/20 as decimal*percent
