The scale of a map is 1 : 100,000. The distance between two houses on the map is 3.2 cm. Find the actual distance, in kilometers
goldenfox [79]

Answer:

The actual distance between the two houses is:

3.2 km

Step-by-step explanation:

Proportions:

1cm       ⇔  100000 cm

3.2 cm  ⇔  W cm

W = 3.2*100000/1

W = 320000 cm

1 km = 100000 cm

320000cm = 320000/100000 = 3.2km

Find the perimeter of this semi-circle with diameter,
yan [13]

Answer:

The answer to your question is  P = 17(π + 2) or 17π + 34

Step-by-step explanation:

Data

Diameter = 34 cm

Formula

P = rπ + 2r

Process

1.- Find the radius

radius = diameter / 2

radius = 34 / 2

radius = 17 cm

2.- Substitute the values in the formula

P = 17π + 2(17)

3.- Simplification

P = 17π + 34

4.- Factor

P = 17(π + 2)

What is the distance between points F(6, 4) and G(14, 19)?
vredina [299]

Answer:

(-8,-15)

Step-by-step explanation:

(6,4) (14,19)

So, to find the distance you need to subtract from the x axis on both coordinates and the y axis on both coordinates.

(6-14) (4-19)

6-14= -8

4-19= -15

I also graphed it as well, so it should be correct.

(-8, -15)
