Answer:
c
Step-by-step explanation:
Since the figures are similar then the ratios of corresponding sides are equal, that is
=
, substitute values
=
( cross- multiply )
10YZ = 230 ( divide both sides by 10 )
YZ = 23 → c
5 red, 3 blue, 7 white.....total of 15
probability of 1st drawn being red : 5/15 reduces to 1/3
without replacement
probability of 2nd being red : 4/14 reduces to 2/7
probability of both : 1/3 * 2/7 = 2/21 <==
Answer:
The answer is dilation by a scale factor of 2 followed by reflection about the y- axis.

Answer:
20:15
Step-by-step explanation:
baiscally add 4:3
4+3=7
then take the total of 35 and divide it by 7 you'd get 5.
4x+3x=35
7x=35
1x=5
4x=5×4=20
3x=5×3=15
4:3 therefore would be 20:15
Step-by-step explanation:
There can only be 2 location which is to the right and to the left, this is because it means the difference between is 9. So the two answers are…
