Answer:

The distance from sea level in mm is 0.5494 mm.

Step-by-step explanation:

Consider the provided information.

It is given that Our scale is that 100 mm on the map is equal to 6371 km in Earth.

This can be written as:

100 mm = 6371 km

Divide both the sides by 6371.

100/6371 mm = 1 km

We need to find the distance from sea level in mm, if the distance is 35 km.

Multiply both sides by 35.

100/6371 × 35 mm = 1 × 35 km

0.5494 mm = 35 km

Hence, the distance from sea level in mm is 0.5494 mm.

Venus and Serena measured a tennis court and found that it was 42ft longer than it was wide and had a perimeter of 228ft. What w
mr_godi [17]

Answer:

length = 78 feet

width = 36 feet

Step-by-step explanation:

Using one variable and an expression, you can set up an equation equal to the perimeter to find the measure of each side:

width = 'w'

length = '42ft longer than it was wide' = w + 42

The general formula for the perimeter of a rectangle:

P = 2w + 2l

Plugging in the given values and variables:

228 = 2w + 2(w + 42)

Distribute: 228 = 2w + 2w + 84

Combine like terms:  144 = 4w

Divide and solve:  36 = w

w = 36 ft

l = 36 + 42 = 78 ft

Points A,B, and C are collinear. Points M and N are the midpoints of segments AB and AC. Prove that BC = 2MN
irinina [24]
Look at the picture.

1)|AM| = |MB| = x
|AN| = |NC| = y
|BC| = 2y - 2x = 2(y - x)
|MN| = y - x
Therefore |BC| = 2|MN|
2)|AM| = |MB| = x
|AN| = |NC| = y

|BC| = 2y - 2x = 2(y - x)
|MN| = y - x
Therefore |BC| = 2|MN|
