vlada-n [284]
30. Answer if u place the equation into a fraction: example 20/8 yellow over red. Next let’s put the other amount into a fraction, we don’t know yellow so for the fraction we will put x: x/18. For our next step we will then cross multiply 20 by 18 and 8 by x getting 8x=360 from there you divide for x getting 45 yellow.

Find the slope of the line that passes through<br><br><br> (7,-1) and (9,0)
mafiozo [28]

Answer:

1/2 or 0.5

Step-by-step explanation:

so to find the slope of two points you use the slope formula which is rise over run, y2-y1/x2-x1. so that would be -1-0/7-9. leading to -1/-2. so the slope is 1/2 or 0.5.

Help plz<br>Find the measurement of the angles of a triangle if they are in the ratio 5:4:3 ​
Lerok [7]

Answer:

<u>See below:</u>

Step-by-step explanation:

Let the angles be 5x , 4x , 3x.[Since the angles are in ratio 5:4:3 ] respectively.

We know that sum of all angles of a triangle is 180°.

So,

5x + 4x + 3x = 180   {}^{ \circ}

Now Find the value of x of this equation.

\sf  \implies \: 5x + 4x + 3x = 180 {}^{ \circ}

\sf  \implies12x = 180 {}^{ \circ}

\sf  \implies \: x =  \cfrac{180 { {}^{ \circ} }}{12}

\sf  \implies \: x =  \cfrac{ \cancel{180 {}^{ \circ}} }{  \cancel{12}}

\sf  \implies \: x = 15 {}^{ \circ}

Now,

Multiply each ratio given by 15 which is the value of x we got.

That is;

\therefore \sf\implies \: First \: Angle = 5 \times 15  {}^{ \circ}  = \boxed{75 {}^{ \circ}}

\sf \sf  \implies \: Second\: Angle = 4\times 15  {}^{ \circ}  = \boxed{60 {}^  \circ}

\sf  \implies \: Third\: Angle = 3 \times 15 =  \boxed{ {45}^ \circ}

Hence,the measurements of the angles of the triangle would be 75°[First Angle],60°[Second angle],and 45° [Third Angle].

\rule{225 pt}{2pt}

I hope this helps!

Let me know if you have any questions.
