Answer:
D. 100
Step-by-step explanation:
percents are always out of 100 because that is the maximum. if you are 100% done with your homework, you are completely finished.
The required Length is 10cm.
What is length?
- Length is a measure of distance. In the International System of Amounts, length is a volume with dimension distance. In utmost systems of dimension a base unit for length is chosen, from which all other units are deduced.
- Length is generally understood to mean the most extended dimension of a fixed object. still, this isn't always the case and may depend on the position the object is in.
- Varied terms for the length of a fixed object are used, and these include height, which is the perpendicular length or perpendicular extent, and range, breadth, or depth. Height is used when there's a base from which perpendicular measures can be taken. range or breadth generally relates to a shorter dimension when the length is the longest one.
220 / 14 gives us 15.
You have to understand that this means 15 whole 14 cm pieces and a Length of 1 piece.
thus 14 * 15 = 210
So 220- 210 = 10
where you know 220- 210 is< 15
Hence, The correct Length is 10cm.

Answer:
D ! :))
Step-by-step explanation:
Answer:
See below ~
Step-by-step explanation:
1.
- x² + y² + 14x - 2y = -1
- [x² + 14x + 49] - 49 + [y² - 2y + 1] - 1 = -1
- (x + 7)² + (y - 1)² = 49
- Centre = (x, y) = (-7, 1)
- Radius = √49 = 7
2.
- x² + y² - 10x + 8y - 8 = 0
- [x² - 10x + 25] - 25 + [y² + 8y + 16] - 16 - 8 = 0
- (x - 5)² + (y + 4)² = 49
- Centre = (x, y) = (5, -4)
- Radius = √49 = 7
3.
- Points are : (-2, 1) and (4, 3)
- D = √(4 + 2)² + (3 - 1)²
- D = √36 + 4
- D = √40
- D = 2√10
