Express each ratio as a unit rate.round to the bearest tenth,if necessary. 2 note books for $0.60
FrozenT [24]

Option B

2 notebooks for $ 0.60 expressed as unit rate is $ 0.30 per notebook

<h3><u>Solution:</u></h3>

We have to express ratio as unit rate

Given that, 2 notebooks for $ 0.60

Number of notebooks = 2

Cost of 2 notebooks = $ 0.60

So we have to find cost of 1 notebook

\begin{array}{l}{\text { cost of } 1 \text { notebook }=\frac{\text { cost of } 2 \text { notebook }}{2}} \\\\ {\text { cost of } 1 \text { notebook }=\frac{0.60}{2}=0.30}\end{array}

So unit rate = cost of 1 notebook = $ 0.30

So 2 notebooks for $ 0.60 as unit rate is $ 0.30 per notebook

Raul and his friends each way 1/20 of a ton are standing on a truck scale . The total weight shown by the scale is 3/4 of a ton
vivado [14]

Answer:

<em>15 people</em>

Step-by-step explanation:

since Raul and his friends each weigh 1/20 ton,

and the total weight reads 3/4 ton

The total number pf people on the scale will be:

<em>The total weight of Raul and his friends divided by their individual weight</em>

==> (3/4 ton) ÷ (1/20 ton)

= 3/4 X 20/1 = <em>15 people</em>

Express the complex number in trigonometric form. -6 + 6 square root of 3 i ?
bagirrra123 [75]
\bf \begin{array}{clclll}&#10;-6&+&6\sqrt{3}\ i\\&#10;\uparrow &&\uparrow \\&#10;a&&b&#10;\end{array}\qquad &#10;\begin{cases}&#10;r=\sqrt{a^2+b^2}\\&#10;\theta =tan^{-1}\left( \frac{b}{a} \right)&#10;\end{cases}\qquad r[cos(\theta )+i\ sin(\theta )]\\\\&#10;-------------------------------\\\\

\bf r=\sqrt{(-6)^2+(6\sqrt{3})^2}\implies r=\sqrt{36+(6^2\cdot 3)}\implies r=\sqrt{144}&#10;\\\\\\&#10;r=12\leftarrow &#10;\\\\\\&#10;\theta =tan^{-1}\left( \frac{6\sqrt{3}}{-6} \right)\implies \theta =tan^{-1}\left( -\sqrt{3}\right)\implies \theta =&#10;\begin{cases}&#10;\frac{2\pi }{3}\leftarrow \\&#10;\frac{5\pi }{3}&#10;\end{cases}

now, notice, there are two valid angles for such a tangent, however, if we look at the complex pair, the "a" is negative and the "b" is positive, that means, "x" is negative and "y" is positive, and that only occurs in the 2nd quadrant, so the angle is in the second quadrant, not on the fourth quadrant.

thus         \bf 12\left[cos\left( \frac{2\pi }{3} \right) +i\ sin\left( \frac{2\pi }{3} \right) \right]
