Answer:

24 blue cars

Step-by-step explanation:

Set up a proportion to solve this...

40/5 = x/3      (forty red cars is to five red cars as 'x' number of blue cars is to 3 blue cars)

Now solve by cross multiplying...

120 = 5x

    24 = x

Triangle ABC has vertices at (-4,0) (-1,6) and (3,-1) What is the perimeter of triangle ABC rounded to the nearest tenth.
Marizza181 [45]
Here, Vertices: A(-4, 0) B(-1, 6) C(3, -1)

Length of AB = √(6 - 0)² + (-1 + 4)²
= √6² + 3²
= √45

Length of BC = √(-1-6)² + (3+1)²
= √-7² + 4²
= √65

Length of AC = √(0+ 1)² + (-4 - 3)²
= √1² + 7²
= √50

Perimeter = sum of all sides:
So, P = √45 + √65 + √50 = √160 = 4√10

In short, Your Answer would be 4√10 units

Hope this helps!

What is the measure of n? <br>​
tia_tia [17]

Answer:

n = √108 or 6√3

Step-by-step explanation:

n is the altitude of the right triangle

Based on the right triangle altitude theorem, we would have:

h = √(xy)

Where,

h = n

x = 18

y = 6

Substitute

n = √(18*6)

n = √108

Or

n = 6√3
