Hypothesis (p): A polygon is a square
Conclusion: (q): It is a rectangle
Inverse: q → p <em>If a polygon is a rectangle, then it is a square</em>
Converse: ~p → ~q <em>If a polygon is not a square, then it is not a rectangle.</em>
Contrapositive: ~q → ~p <em>If a polygon is not a rectangle, then it is not a square</em>
Your answers are correct
Its simple, convert 1 and 2/3 into a fraction which is 5/3 and use KCF which is Keep Change and Flip,
How this works is that you keep the first fraction, then change the division sign to a multiplication sign (Change = change the sign into its oppisite) then flip the other fraction from being 5/3 into 3/5. And then you multiply top times top and bottom times bottom. After that you simplify if you can, Hope this helped!
X is equal to 12 and y is equal to 8
<h2>The cost is same for both the options if we purchase 27 photos</h2>
Step-by-step explanation:
Cost of a photo at a local store is $0.25 per photo. This cost can be modeled to be linear in number of photos as 
.
Cost of photos purchased online is $0.15 per photo. However there is a shipping cost of $2.70. This can also be modeled to be linear in number of photos as 
.
Let us assume both costs are the same if we purchase 
photos.
So, 
∴ On purchasing 27 photos, cost for both the options is the same.
No because 77 is greater than the lowest number
