1/5 - 3/10 = - 1/10
5/8 - 1/2 = 1/8
13/20 + 2/10 = 17/20
3/5 + 3/15 = 12/15

The expression that has a value of 62.45 is the second answer choice 0.6245 × 10²
To determine the expression that has a value of 62.45 among the given answer choices, we will evaluate each of the answer choices.
- For the first answer choice - 0.006245 × 105 = 0.006245 × 10⁵
0.006245 × 10⁵ = 624.5
- For the second answer choice - 0.6245 × 102 = 0.6245 × 10²
0.6245 × 10² = 62.45
- For the third answer choice - 6.245 ÷ 101 = 6.245 ÷ 10¹
6.245 ÷ 10¹ = 0.6245
- For the fourth answer choice - 624.5 × 103 = 624.5 × 10³
624.5 × 10³ = 624500
From above, the second answer choice is the expression that has a value of 62.45
Hence, the expression that has a value of 62.45 is 0.6245 × 10²

Answer:
10
Step-by-step explanation:
In a polygon
interior angle + interior angle = 180°, thus
exterior angle = 180° - 144° = 36°
The sum of the exterior angles in a polygon = 360°, thus
number of sides = 
= 10
|r|-12=23
|r|=23+12
|r|=35
r=+/-35
