Find the coordinates of the point P that divides the directed line segment from A to B in the given ratio. A (-5, 12) B (11, 0)
zhenek [66]

Answer:

(7, 3)

Step-by-step explanation:

Using the midpoint formula

M(X, Y) = {(ax1+bx2/a+b), ay1+by2/a+b}

X = ax1+bx2/a+b

X = -5(1)+3(11)/1+3

X = -5+33/4

X = 28/4

X = 7

Y = ay1+by2/a+b

Y = 1(12)+3(0)/1+3

Y = 12/4

Y = 3

Hence the coordinate of P is at (7, 3)

The area of Erin's circle to the nearest hundredth is 50.24 in².

<h3>What is the area of the circle?
</h3>

A circle is a bounded figure which points from its center to its circumference is equidistant.

Area of a circle = πr²

Where :

  • π = pi = 3.14
  • R = radius

3.14 X 4²

(3.14) (4) (4) = 50.24 in²

Pastries made out of filo dough and brushed with either olive oil or butter (but not both). Pastries made out of shortcrust doug
Genrish500 [490]

Answer:

\frac{9x}{40} is the answer.

Step-by-step explanation:

The question has some typo errors.

Rashid and Mikhail submitted a total of x pastries to a baking competition.

Suppose say :

Mikhail made x pastries .

Hence Rashid made \frac{2x}{3} pastries.

And in total they made \frac{5x}{3} pastries.

Now we have that out of x, \frac{5}{8} of x were brushed with olive oil.

So, \frac{3}{8} of x that is \frac{3x}{8} are brushed by butter.

So, it becomes (\frac{3}{8}) / ( \frac{5x}{3} )

= \frac{3}{8} \times\frac{3x}{5} = \frac{9x}{40}

Hence, answer is option B.
