\frac{9}{20} of the class consists of freshmen.

Step-by-step explanation:

Given,

Total number of students = 40

Number of freshmen = 18

Number of sophomores = 19

Number of juniors = 3

Fraction of freshmen = \frac{Number\ of\ freshmen}{Total\ number\ of students}

Fraction of freshmen = \frac{18}{40}

Fraction of freshmen = \frac{9}{20}

\frac{9}{20} of the class consists of freshmen.

Finger [1]

Answer:

The length of the necklace is 12.20 foot

Step-by-step explanation:

Given as :

The height of the ice cream cone to the ground = h = 10 foot

The angle make by the necklace of the ice cream cone = 55°

Let The length of the necklace = L foot

<u>Now, from figure </u>

Height = BC = h foot

The length of the necklace = L = AC

So, Sin angle = \dfrac{\textrm perpendicular}{\textrm hypotenuse}

Or, Sin 55° = \dfrac{\textrm BC}{\textrm AC}

Or, 0.8191 = \dfrac{h}{L}

Or, 0.8191 = \dfrac{10 foot}{L}

Or, L = \dfrac{10 foot}{0.8191}

∴  L = 12.20 foot

So, The length of necklace = L = 12.20 foot

Hence The length of the necklace is 12.20 foot Answer

Answer:

slope is -1

Step-by-step explanation:

Slope of the line is changes in y over changes in x. It can also be referred as rise over run.

We can express mathematically as:

\displaystyle{m=\dfrac{y_2-y_1}{x_2-x_1}}

where m is slope.

Let (-2,5) be \displaystyle{(x_2,y_2)} and (6,-3) be \displaystyle{(x_1,y_1)}. Hence, apply the slope formula:

\displaystyle{m=\dfrac{5-(-3)}{-2-6}}\\\\\displaystyle{m=\dfrac{5+3}{-8}}\\\\\displaystyle{m=\dfrac{8}{-8}}\\\\\displaystyle{m=-1}

Therefore, the slope is -1
