Let number of one rupee coins be x
Let number of two rupee coins be 2x
=> 2x+x=30
=>3x=30
=> x = 10
Hence , number of one rupee coints are x = 10
Number of 2 rupee coins are 2x = 2(10) = 20
Hope this helps you dear:)
Have a good day!
Answer: option D is the answer
Step-by-step explanation:
The answer is A. 16 edges
Euler's polyhedron formula:
f + v - e = 2
f - the number of faces
v - the number of vertices
<span>e - the number of edges
</span>
f = 5 congruent <span>squares + 4 congruent equilateral triangles = 9
v = 9
e = ?
f + v - e = 2
e = f + v - 2
e = 9 + 9 - 2
e = 16</span>
<span>There is a requirement for the Coast Guard that all vessels must be registered with the state in which they'll be operated and their registration numbers must be clearly displayed on the boat.
