George is given two circles, circle o and circle x, as shown. if he wants to
prove that the two circles are similar, what would be the correct fourth step in
his proof?
given: the radius of circle ois r, and the radius of circle
prove: circle o is similar to circle x.
1.c = 2x7 and c = 251' by the definition of circumference.
2.
= 33%, and
by the division property of equality.
3. d = 2r and d = 21 by the definition of diameter.
5.
and
by the substitution property.
6. circle ois similar to circle x because all the linear dimensions are in the
same proportion

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true

i don't think there is enough

a is the best answer choice
