We know that
The sum of exterior angles of any polygon is 360 degrees.
Each exterior angle of a regular polygon = 360/n
where n is the number of sides.
<span>So
n = 360/20 = 18
</span>
the answer is the option
<span>b.18 </span>
Answer:
D
Step-by-step explanation:
Answer:
There will be 135 squares in total. Changing the order of the factors wont change the result.
Step-by-step explanation:
(i am assuming that sqaures = sqaure pieces)
Each section has 3 rows of 15 square pieces, therefore each section has 3*15 = 45 sqaure pieces. Thus, the complete guilt will have 45*3 = 135 square pieces. Since all we do were multiplications, changing the order of the factors wont change the value of the product.
First you solve for X then substitute the number you got for X and then solve for Y.
The equation computed shows that the number of days until both containers have the same weight of food in them will be 12 days.
<h3>How to calculate the equations?</h3>
From the information given, the instructions say to feed the old dog 2/3 pound of food each day from the bin with 25 lbs of kibble in it. the equation will be:
= 25 + 2/3d
= 25 + 0.67d
Also, the puppy is to get 1/4 pound of food each day from the bag with 20 lbs of puppy kibble in it. This will be:
= 20 + 1/4d
= 20 + 0.25d
The number of days until both containers have the same weight of food in them will be:
25 + 0.67d = 20 + 0.25d
0.67d - 0.25d = 20 - 25
0.42d = 5
d = 5/0.42
d = 11.9
d = 12 days
