Step-by-step explanation:
Given
<u>Circle C</u>
--- radius
--- center
<u>Circle E</u>
--- center
Required
Prove their similarity
Translate circle C 8 units up;
The rule is:
So, we have:
Translate circle C' 7 units right;
The rule is:
So, we have:
<em>At this point, both circles now have the same center at (4,9)</em>
The next step is to dilate circle E by 4/3
This will only affect radius and not the center of E
The rule is:
So, we have:
-- equal radii
--- equal center

Answer:
(a)
(b) We cross multiply the probability by the total voters
(c) 9347
Step-by-step explanation:
(a)
Probability of getting a republican voter is
These are found by dividing the first numerator and denominator by 2, then by 3
To make it complete, the situation is therefore defined as where y is unknown value
(b)
Cross multiplication of the probability and number of voters gives the actual figure of y in the equation formed in part a of the question.
(c)
Since we have 15240 voters who plan to participate in election, we cross multiply to get the approximate number of republican voters which yields
