Two figures are similar are one of them can be obtained from the other with some transformations (reflections, translations, rotations, dilations) <span> . The circle is defined by only one length - the radius.
</span>
To prove that all circles are similar you would use the sequence of similarity translation and dilation.
A translation, followed by a dilation with scale factor r2/r1 will map one circle onto the other, thus proving that the circles are similar.
Answer:
$11.43
Step-by-step explanation:
use a calculator and type in 76.25 + 15%, which will equal 87.68.
Then you subtract 76.25 from 87.68. 87.68 - 76.25 = 11.43.
A 15% tip would be $11.43

Answer: -8/3
Step-by-step explanation:
Multiplying a positive and a negative equals negative: (+)•(-)=(-)
y= - 2/3•4
Y= -8/3
Step-by-step explanation:
The key to solving word problems is in translation: turning word into math
Below is a general approach to most/any word problem
1. Read through the whole question once, without lingering over details, to get some sense of the overall problem
2. identify and label the variables or unknowns in a way that makes it easy to remember what they stand for.
3. translate the problem into one or more equations, sentence by sentence, and be careful of the order in which you translate the terms
4. solve the equation(s)
5. check your work
