Here is how to solve it.
65% of 160
65/100(160)
=(65/100)(160/1)
=(13/20)(160/1)
=(13)(160)/(20)(1)
=2080/20
=104
Therefore they won 104 games! :D
1. The counterclockwise rotation by 90° about the origin has rule:
(x,y)→(-y,x).
Then
(-3,-1)→(1,-3).
2. Translation 4 units up has rule:
(x,y)→(x,y+4).
Then
(1,-3)→(1,1).
Answer: after composition of transformations the image point has coordinates (1,1).
A ratio shows us the number of times a number contains another number. The correct option is C.
<h3>What is a Ratio?</h3>
A ratio shows us the number of times a number contains another number.
For winning less than $10, a person needs to take out a green ticket or a yellow ticket. Therefore, the odds against winning less than $10 are,
(Number of blue tickets) : (Number of green and yellow tickets)
5: 30
1: 6
Hence, the correct option is C.

Answer:
6.28
Step-by-step explanation:
You need to find the circumference,
so 2*3.14*R
the radius is 4 so
2*3.14*4
25.12
now you have found the length of the full circle, you need to find a quater like because there is 4 90 degres in a circle
so divide you answer by 4
πr2 is an example of a (D) model.
<h3>What exactly is a model?</h3>
- A mathematical model is a system description that makes use of mathematical concepts and language.
- The process of developing a mathematical model is known as mathematical modeling.
- Natural sciences (physics, biology, earth science, chemistry), engineering disciplines (computer science, electrical engineering), and non-physical structures such as the social sciences all use mathematical models (such as economics, psychology, sociology, and political science).
- The use of statistical equations to solve problems in business or military operations is a large part of the field of operations research.
- Mathematical models are used in music, linguistics, and philosophy (for example, intensively in analytic philosophy).
- A model is, for example, the πr2 method for calculating the area of a circle.
Therefore, πr2 is an example of a (D) model.
