How many different homomorphisms o : z/5zz/20z are there?

2

Step-by-step explanation:

We are given that

We have to find number of different homomorphisms

We know that

Z/5Z is isomorphic to and isomorphic to

We know that

If

Number of homomorphism=gcd(m,n)

Gcd(5,10)=2

5 does not divide by 20 therefore, there are no onto homomorphisms.

There are only two homomorphisms.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

hi there!

the answer to this question is d: 35

step-by-step explanation:

5 to the power of 2 is 25

2 multiplied by 5 is 10

then you add the 2 numbers and you get 35
