Emanuel was charged $32 for a 14 2/9km taxi ride What was the cost per kilometer?
scoray [572]
Answer: 1km = 2.25$

Explanation:
32 = 14 2/9
32 = 128/9 (make it into fraction by taking 14 x 9 + 2)

32 divide by 128/9 = 128/9 divide by 128/9 (divide both sides by 128/9)

32 x 9/128 = 128/9 x 9/128
9/4 = 1
2.25$ = 1km

Find the coordinates of the circumcenter for ∆DEF with coordinates D(1,3) E (8,3) and F(1,-5). Show your work.
luda_lava [24]

Answer: The coordinates of the circumcenter is (\frac{9}{2}, -1).

Explanation:

The coordinates of triangle DEF are D(1,3) E (8,3) and F(1,-5).

Distance formula,

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

DE=\sqrt{(8-1)^2+(3-3)^2}=7

FE=\sqrt{(1-8)^2+(-5-3)^2}=\sqrt{7^2+8^2}

DF=\sqrt{(1-1)^2+(-5-3)^2}=8

Since triangle follows pythagoras theorem,

(DF)^2+(DE)^2=(FE)^2

Therefore the given triangle is a right angle triangle.

Or plot these points on a coordinate plane. From the figure we can say that the triangle DEF is a right angle triangle.

The circumcenter of a right angle triangle is the midpoint of the hypotenuse.

The hypotenuse is EF. The midpoint of EF is,

Midpoint =(\frac{8+1}{2}, \frac{3-5}{2} )=(\frac{9}{2}, -1)

Therefore, the coordinates of the circumcenter is (\frac{9}{2}, -1).

Two triangles intersecting in one point, two points, three points, four points, five points, or six points
Kitty [74]
In your question which ask for the how its possible for the two triangles to intersect in one, two, three, four, five, six points but not seven points. Its because the triangles has only 3 sides which means that the intersection that could from in the two is less than 7 or maximum of 6
