The formula of a distance between two points:
We have the points (-1, 8) and (5, -2). Substitute:
Answer:
Step-by-step explanation:
Set up an equation, where x is the number of gallons of 60% antifreeze solution.
Represent the percentages of antifreeze with decimal values.
0.6x + 0.3(80) = 0.5(x + 80)
Simplify and solve for x:
0.6x + 24 = 0.5x + 40
0.1x = 16
x = 160
So, you have to mix 160 gallons of a 60% antifreeze solution
the center of gravity of all triangles is at the intersection of the three midlines.
2) The area of the three boy gogle fermed by the line from the center of gravity of the triangle to each verten is equal, which is 1/3 of the area of the origiend briangle. 6o we can see that selecting option. 60 C is shown in figura.
the answer is c
