Answer:
its -5 just took the test
Step-by-step explanation:
Tax = 7 1/4% = 29/4
After tax, it would be, 89.79 + 89.79*29/4*100 = 89.79 + 2589.41/400
= 89.79+6.47 = $96.26
So,
We start with 0 + 40.
1. 0 + 40
2. 1 + 39
3. 2 + 38
4. 3 + 37
...
...
...
19. 18 + 22
20. 19 + 21
21. 20 + 20
Tada! There are 21 pairs of whole numbers that have a sum of 40.
Answer:
3/2
Step-by-step explanation:
Because the problem tells you that the two triangles are similar, the value of a/b would be equivalent for both triangles. The fact that they are right triangles also indicates which sides are which in case the image was not drawn to scale. A is proportional to 2.1 and b is proportional to 1.4. So a/b= 2.1/1.4. This can reduce itself to 3/2 because both are divisible by .7
