Answer:
Step-by-step explanation:
6)For question 6 you have the right idea but as the new image is bigger than the pre-image the scale factor would be 3/1
7)You have the right answer but the fraction can be simplified to 2
8)I think this question is asking for the angle in the triangle on the left that is the same as the one on the right so from left to right,
F=R G=S H=T
FG=RS GH=ST FH=RT
9)The scale facto for the longest edge here is 2 but the scale factor for the shortest edge is 18/8 which is equal to 9/4 so the are not congruent as they have two different scale factors. Answer) no
10) the triangles are similar as angle a=n and 55+35+90 = 180 so yes they are similar
Hope this helps :)
Answer:
Step-by-step explanation:
Given
i.e. 10 people
Required
Probability of being next to each other
First, we calculate the total possible arrangements (without any restriction)
If the three are to be next to each other,
First, we arrange the three
Now, the 3 will be seen as 1; so, we have a total of 8 people i.e. (1 + 7 others)
The arrangement is:
So, the total arrangement, when they have to be next to one another is:
The probability is:
Expand
Express as percentage
The answer = B because of the pattern
