Please help me Which number is not an appropriate result?
A - a shopping receipt that totals $4.90

B - a soccer game where the average score is 4.7

C- a stack of 15.6 watermelons

D- a classroom with 24 students

C - a stack of 15.6 watermelons

Step-by-step explanation:

Lets first go through each option:

"A shopping receipt that totals $4.90":

This is an appropriate answer since many items sold are not priced at exact dollars (where there are no cents), so having $4.90 as the total cost after shopping is appropriate.

"A soccer game where the average score is 4.7":

This is also an appropriate result since it is the average score of a soccer game, so finding a decimal is appropriate.

"A stack of 15.6 watermelons":

This is not an appropriate result since it would be strange to say a 'stack' or group of something that is not a whole number.

"A classroom with 24 students":

This is an appropriate result since the number of students is a whole number not a decimal.

Hope this helps :)

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
