Answer: Justin: 21 dollars, Raina: 16 dollars, Cho: 42 dollars.

Step-by-step explanation:

Let's say that Justin has x dollars.

Since Raina has 5 dollars less than Justin, Raina has (x - 5) dollars.

Since Cho has 2 times of what Justin has, Cho has 2x dollars.

In total, they have 79 dollars. So by adding up our quantities, they will equal 79 dollars.

x + (x - 5) + 2x = 79

So: 4x - 5 = 79

So 4x = 84

So x = 21

Therefore Justin has 21 dollars

Since Raina has 5 dollars less than Justin, Raina has 16 dollars

Since Cho has 2 times of Justin, Cho has 42 dollars

Triangle A B C is cut by line segment S T. Line segment S T goes from side A B to side C B. Lines S T and A C are parallel. The
maksim [4K]

Answer:

Option C.

Step-by-step explanation:

Given information: In triangle ABC, ST║AC, SB=10 ft, BT=9 ft and CT=2.7 ft.

Triangle proportionality theorem: If a line segment parallel to a side of a triangle then the line segments divides the remaining sides proportionally.

Using triangle proportionality theorem we get

\dfrac{SA}{SB}=\dfrac{CT}{BT}

\dfrac{SA}{10}=\dfrac{2.7}{9}

On cross multiplication we get

9\times SA=2.7\times 10

9SA=27

Divide both sides by 9.

SA=3

The length of SA is 3ft.

Therefore, the correct option is C.

18n^2-50=0\ \ \ |+50\\\\18n^2=50\ \ \ |:18\\\\n^2=\dfrac{50}{18}\\\\n^2=\dfrac{50:2}{18:2}\\\\n^2=\dfrac{25}{9}\to n=\pm\sqrt{\dfrac{25}{9}}\\\\n=\pm\dfrac{\sqrt{25}}{\sqrt{9}}\\\\\boxed{n=-\dfrac{5}{3}\ \vee\ n=\dfrac{5}{3}}

Used:\\\sqrt{\dfrac{a}{b}}=\dfrac{\sqrt{a}}{\sqrt{b}}
