So, we know the segment MP gets partitioned by the point A to MA with a ratio of 2 and AP with a ratio of 1, on a 2:1 ratio from M to P, therefore then,

\bf \left. \qquad  \right.\textit{internal division of a line segment}
\\\\\\
M(1,4)\qquad P(16,14)\qquad
\qquad 2:1
\\\\\\
\cfrac{MA}{AP} = \cfrac{2}{1}\implies \cfrac{M}{P} = \cfrac{2}{1}\implies 1M=2P\implies 1(1,4)=2(16,14)\\\\
-------------------------------\\\\
{ A=\left(\cfrac{\textit{sum of "x" values}}{\textit{sum of ratios}}\quad ,\quad \cfrac{\textit{sum of "y" values}}{\textit{sum of ratios}}\right)}

\bf -------------------------------\\\\
A=\left(\cfrac{(1\cdot 1)+(2\cdot 16)}{2+1}\quad ,\quad \cfrac{(1\cdot 4)+(2\cdot 14)}{2+1}\right)
\\\\\\
A=\left( \cfrac{1+32}{3}~~,~~\cfrac{4+28}{3} \right)\implies A=\left( \cfrac{33}{3}~~,~~\cfrac{32}{3} \right)
\\\\\\
A=\left(11~~,10\frac{2}{3}  \right)

Help Me Pleaseeee A square is cut out of a circle whose diameter is approximately 14 feet. What is the approximate area (shaded
Setler [38]

Answer:

(4\pi -2)49

Step-by-step explanation:

let radius of the circle be r = 14 feet.

then side of the square would be \sqrt{2}r

therefore area of the square = 2r^{2}

area of remaining circle = area of circle - area of square

                                        4\pi r^2-2r^{2}

                                        =(4\pi -2)49

In parallelogram DEFG, DH = x + 1, HF = 3y, G H = 3 x − 4 , GH = 3x - 4, and HE = 5y + 1. Find the values of x and y. The diagra
timofeeve [1]

keeping in mind that in a parallelogram the diagonals bisect each other, namely cut each other into two equal halves.  Check the picture below.

\stackrel{GH}{3x-4}~~ = ~~\stackrel{HE}{5y+1}\implies 3x=5y+5\implies x=\cfrac{5y+5}{3} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{DH}{x+1}~~ = ~~\stackrel{HF}{3y}\implies \stackrel{\textit{substituting "x" in the equation}}{\cfrac{5y+5}{3}+1~~ = ~~3y}

\stackrel{\textit{multiplying both sides by }\stackrel{LCD}{3}}{3\left( \cfrac{5y+5}{3}+1 \right)=3(3y)}\implies 5y+5+3=9y\implies 5+3=4y\implies 8=4y \\\\\\ \cfrac{8}{4}=y\implies \boxed{2=y}~\hfill x=\cfrac{5y+5}{3}\implies x=\cfrac{5(2)+5}{3}\implies \boxed{x=5}

A bucket holds 2 liters of water. How many milliliters of water can the bucket hold?
Nezavi [6.7K]

The number of milliliters of water that the bucket can hold is 2000 milliliters.

First and foremost, it's important to know that 1000 milliliters is thesame thing as 1 liter.

Therefore, for one to get the number of milliliters in 2 liters, one will have to multiply 1000 milliliters by 2. This will be:

= 1000 milliliters × 2

= 2000 milliliters

Also, you can do the same for other figures too e.g. for 5 liters will be:

= 5 × 1000 milliliters

= 5000 milliliters.

In conclusion, the number of milliliters of water that the bucket can hold is 2000 milliliters
