(B=wrong | 15/79=.19)
(C=correct | 20/79=.253)
Answer:
S₉ = 255.5
Step-by-step explanation:
the sum to n terms of a geometric sequence is
= 
where a₁ is the first term and r the common ratio
here a₁ = 0.5 and r = 
= 
= 2 , then
S₉ = 
= 
= 0.5(511)
= 255.5
Answer:
18.225
Step-by-step explanation:
You do the -3 power to 4/9 first then multiply by 8/5 to get your answer.
Answer:
AB is longer than FD
Step-by-step explanation:
I took the quiz on edge
Answer:
Segment US and segment JH.
Step-by-step explanation:
Since the triangles are triangles STU and HIJ, angle I would corrsepond to angle T and angle U would correspond to angle J. Therefore, they are not congruent.
I'm not sure what there might be on the diagram, but according to the way the triangles are organized, segment TU would correspond to segment IJ while segment HI would correspond to segment ST. So, segments TU and HI are not congruent.
Angle I would correspond to angle T and angle S to angle H, so angles I and T are not congruent.
Segment US would correspond to segment JH, so those two corresponding parts are congruent.
Hope this helps!
