Can anyone figure this out?

$\bf ~~~~~~~~~~~~\textit{distance between 2 points} \\\\ N(\stackrel{x_1}{-3}~,~\stackrel{y_1}{10})\qquad A(\stackrel{x_2}{6}~,~\stackrel{y_2}{3})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ NA=\sqrt{(6+3)^2+(3-10)^2}\implies NA=\sqrt{130} \\\\[-0.35em] ~\dotfill\\\\ A(\stackrel{x_2}{6}~,~\stackrel{y_2}{3})\qquad D(\stackrel{x_1}{6}~,~\stackrel{y_1}{-1}) \\\\\\ AD=\sqrt{(6-6)^2+(-1-3)^2}\implies AD=4 \\\\[-0.35em] ~\dotfill$

$\bf D(\stackrel{x_1}{6}~,~\stackrel{y_1}{-1})\qquad N(\stackrel{x_1}{-3}~,~\stackrel{y_1}{10}) \\\\\\ DN=\sqrt{(-3-6)^2+(10+1)^2}\implies DN=\sqrt{202}$

now that we know how long each one is, let's plug those in Heron's Area formula.

$\bf \qquad \textit{Heron's area formula} \\\\ A=\sqrt{s(s-a)(s-b)(s-c)}\qquad \begin{cases} s=\frac{a+b+c}{2}\\[-0.5em] \hrulefill\\ a=\sqrt{130}\\ b=4\\ c=\sqrt{202}\\[1em] s=\frac{\sqrt{130}+4+\sqrt{202}}{2}\\[1em] s\approx 14.81 \end{cases} \\\\\\ A=\sqrt{14.81(14.81-\sqrt{130})(14.81-4)(14.81-\sqrt{202})} \\\\\\ A=\sqrt{324}\implies A=18$

Help i need this **URGENT** brainliest for correct answer

Hunter-Best [27]

Answer:

$\frac{25}{9}$

Step-by-step explanation:

given the ratio of similar sides = a : b , then

ratio of areas = a² : b²

Given

ratio of sides = 5 : 3 , then

ratio of areas = 5² : 3² = 25 : 9 = $\frac{25}{9}$

You have 1/2 pound of flour. You split up the flour into 3 bags so each bag weighs the same. Which of these statements is NOT tr

SIZIF [17.4K]

Given:
1/2 pound of flour
split the flour into 3 bags of equal weight.

1/2 ÷ 3

In dividing fractions, you must remember to get the reciprocal of the 2nd fraction and multiply it to the 1st fraction.

3 is the 2nd fraction. Its reciprocal is 1/3

1/2 * 1/3 = 1/6 pound of flour.

The False statement is:
C. Each bag has 1/3 pound of flour.
