lana [24]

Answer:

  30

Step-by-step explanation:

The midpoint of BC will be a distance from line k that is the average of the distances of B and C: (17+13)/2 = 15. Call that midpoint P. We know distance MP is half of distance MA. This same relationship will hold with respect to the distances from P and A to any line through M. That is, the distance from line k (through M) is twice the distance from P to line k: 30 units.

UNO [17]

Answer:

$1779.896

Step-by-step explanation:

From the above question

1 liter = $143.54

12.4 liters = $x

Cross Multiple

1 liter × $x = 12.4 liters × $143.54

$x = 12.4 liters × $143.54/1 liter

$x = $1779.896

Therefore, the total cost for Stacy gas in dollars and cents is $1779.896

Reil [10]

coordinate of B= (2+3,0) = (5,0)

by pythagoras' theorem,

height of triangle^2 + half length of AB^2 = AC^2

height of triangle^2 = 3^2-1.5^2

height of triangle ^2= 6.75

height of triangle= √6.75

coordinates of C= (1.5,√6.75)
