Just divide the price by the amount bought.
7.96÷5
Which equals 1.592. So round that to 1.59.
The unit price is $1.58 per pound.

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].

I hope this helps!

Answer:

Two variables have a positive association when the values of one variable tend to increase as the values of the other variable increase. Two variables have a negative association when the values of one variable tend to decrease as the values of the other variable increase.
