Answer:
It will be A because of if you round it it would be -7
Answer:
Step-by-step explanation:
Rewrite 13/40 as a fraction over 100:
13/40 = (2 • 6.5)/(2 • 20) = 6.5/20
6.5/20 = (6.5 • 5)/(20 • 5) = 32.5/100
32.5/100 = 0.325
which clearly terminates.

Answer:
option 2 , 3 , 4 , 5
Step-by-step explanation:
Use Pythagorean theorem
hypotenuse² = base² + altitude².
If the lengths satisfies Pythagorean rule, then they form a right angle triangle.
2) 41² = 40² + 9²
1681 = 1600 + 81
1681 = 1681
41, 40 , 9 will form a right angle as it satisfies Pythagorean rule.
3) 15² = 12² + 9²
225 = 144 + 81
225 = 225
9, 12 , 15 will form a right angle as it satisfies Pythagorean rule.
4) 17² = 15² + 8 ²
289 = 225 + 64
289 = 289
17, 15 , 8 will form a right angle as it satisfies Pythagorean rule.
5)53² = 28² + 45²
2809 = 784 + 2025
2809 = 2809
53 , 28 , 45 will form a right angle as it satisfies Pythagorean rule.
