Evaluate the geometric series. Round to the nearest hundredth. Help me please!!

7.50

Step-by-step explanation:

The n th term of a geometric series is

= a

where a is the first term and r the common ratio

5 is the n th term of a geometric series

with a = 5 and r =

The sum to n terms of a geometric series is

= , thus

=

     =

     =

     = × 0.9999..

     = 7.5 × 0.9999...

      ≈ 7.50 ( to the nearest hundredth )

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
