Step-by-step explanation:
just look at the objects !
they are completely regular, and each arm can cover every other other arm.
so,
15A needs 1/3 of a full rotation.
15B needs 1/2 of a full rotation.
15C needs 1/4 of a full rotation.
15D needs (can you guess ?) ... 1/6 of a full rotation.
There isn't enough information to answer this, what is the given area or perimeter?
Answer:
=
Step-by-step explanation:
When dividing values with exponents, we simply need to subtract the numerators exponent to the denominators exponent.
So we have:
=
=
Now since we have a negative exponent, we can get the reciprocal of the value to make it positive.
=
