Answer:
$161.50
Step-by-step explanation:
the revenue for an item of $85 with a 90% markup is $161.50
The length is 20/24 which is reducible to its simpler form of 5/6
Answer:
2r+10-4r+4=32
-2r+14=32
-2r= 32-14
-2r=18
R= -9
Step-by-step explanation:
Answer:
- Yes it is a right triangle
- The side lengths satisfy the Pythagorean theorem equation
Step-by-step explanation:
We can test these numbers to see if they satisfy the Pythagorean theorem equation:
15² = 9² + 12²
225 = 81 + 144 . . . . true
Since the numbers satisy the Pythagorean theorem relation, they belong to a right triangle.
____
You can recognize that the ratio of side lengths is ...
9 : 12 : 15 = 3 : 4 : 5
Further, you can recognize that the side lengths 3, 4, 5 belong to the right triangle with the smallest integer side lengths that satisfy the Pythagorean theorem. Hence the 9 : 12 : 15 triangle is similar (by a scale factor of 3) to a right triangle, thus is a right triangle.
