1/3 of the contestants are dogs and there are 160 dogos.
If:
![\frac{Boys}{20} = 0.45](https://tex.z-dn.net/?f=%20%5Cfrac%7BBoys%7D%7B20%7D%20%3D%200.45)
Soon:
![\frac{Boys}{20} = 0.45 \to Boys = 20*0.45 \to \boxed{Boys = 9}](https://tex.z-dn.net/?f=%5Cfrac%7BBoys%7D%7B20%7D%20%3D%200.45%20%5Cto%20Boys%20%3D%2020%2A0.45%20%5Cto%20%5Cboxed%7BBoys%20%3D%209%7D)
Therefore: (<span>It's not a boy)
</span>Students = 20
Boys = 9
girls = ?
![Girls + Boys = Students](https://tex.z-dn.net/?f=Girls%20%2B%20Boys%20%3D%20Students)
![Girls + 9 = 20](https://tex.z-dn.net/?f=Girls%20%2B%209%20%3D%2020)
![Girls = 20 - 9](https://tex.z-dn.net/?f=Girls%20%3D%2020%20-%209)
![\boxed{Girls = 11}](https://tex.z-dn.net/?f=%5Cboxed%7BGirls%20%3D%2011%7D)
Answer: (Describe the likelihood of not choosing a boy)
Answer:
Part A: D) Mash was heavier by 2 pounds
Part B: B) Mish is growing faster by one pound
Step-by-step explanation:
-- It can't be a right triangle, because the squares of the 2 short sides
don't add up to the square of the longest side.
-- It can't be isosceles, because every isosceles triangle has 2 sides
the same length.
-- It can't be equilateral, because every equilateral triangle has all 3 sides
the same length.
-- So, out of the choices you've listed, this is a <em>scalene</em> triangle.
A scalene triangle is simply one whose sides are all different lengths.
