If PN=29cm and MN=13 , then PM=?

HACTEHA [7]

*see attachment for the figure referred to

Answer/Step-by-step explanation:

1. PN = 29

MN = 13

PM = ?

$PN = PM + MN$ (Segment addition postulate)

$PN - MN = PM$ (subtract MN from each side)

$29 - 13 = PM$ (substitute)

$16 = PM$

$PM = 16 cm$

2. PN = 34, MN = 19, PM = ?

$PN = PM + MN$ (sediment addition postulate)

$PN - MN = PM$ (subtract MN from each side)

$34 - 19 = PM$ (substitute)

$15 = PM$

$PM = 15 cm$

3. PM = 19, MN = 23, PN = ?

$PN = PM + MN$ (Segment addition postulate)

$PN = 19 + 23$ (substitute)

$PN = 42 cm$

4. MN = 82, PN = 105, PM = ?

$PN = PM + MN$ (segment addition postulate)

$PN - MN = PM$ (subtract MN from each side)

$105 - 82 = PM$ (substitute)

$23 = PM$

$PM = 23 cm$

5. PM = 100, MN = 100, PN = ?

$PN = PM + MN$ (Segment addition postulate)

$PN = 100 + 100$ (substitute)

$PN = 200 cm$

A garden has a circular border and a fountain in the center. I measured the distance from one side of the garden to the other, g

Snezhnost [94]

Answer:

The length of the border is approximately 4 feet.

Step-by-step explanation:

Since the garden has a circular border we can apply the formula for the circle's length, which is shown below:

$length = 2*\pi*radius$

Where the radius is half the diameter. The diameter is the distance between two points in the circle going through the center, therefore for this garden the diameter is 1.2 feet and the radius is 0.6 feet. Applying this to the formula gives us:

$length = 2*\pi*0.6\\length = 1.2*\pi\\length = 3.8$

The length of the border is approximately 4 feet.
