Answer:

$\frac{11}{20}$

Step-by-step explanation:

We are told that at the popular restaurant Fire Wok, 55% of guests order the signature dish.

To find the fraction of guests who ordered the signature dish we can write 55% as 55 divided by 100.

$\text{Fraction of guests ordered the signature dish}=\frac{55}{100}$

Upon simplifying our fraction we will get,

$\text{Fraction of guests ordered the signature dish}=\frac{11}{20}$

Therefore, $\frac{11}{20}$ of the guests at the restaurant Fire Wok ordered the signature dish.

A 29-meter ladder is sliding down a vertical wall so the distance between the top of the ladder and the ground is decreasing at

vitfil [10]

Complete question

A 29-meter ladder is sliding down a vertical wall so the distance between the top of the ladder and the ground is decreasing at 7 meters per minute. At a certain instant, the bottom of the ladder is 21 meters from the wall.

What is the rate of change of the distance between the bottom of the ladder and the wall at that instant(in meters per minute)

Answer:

$\frac{dx}{dt}=11.94m/min$

Step-by-step explanation:

From the question we are told that

Slant height $z=29m$

Change in Vertical height $\triangle y=7m/s$

Horizontal length $x=21$

Generally in finding the distance form the top to the bottom of the wall it is mathematically given by

$x^2+y^2=z^2$

$21^2+y^2=29^2$

$y^2=29^2+21^2$

$y=35.81$

Generally solving for the differential equation is mathematically represented as

$x^2+y^2=29^2$

$2x*\frac{dx}{dt} +2y*\frac{dy}{dt} =0$

$x*\frac{dx}{dt} +y*\frac{dy}{dt} =0$

$(21)*\frac{dx}{dt} +(35.81)*(-7) =0$

$(21)*\frac{dx}{dt} -250.64 =0$

$\frac{dx}{dt}=\frac{250.64}{21}$

$\frac{dx}{dt}=11.94m/min$

Question 5(Multiple Choice Worth 1 points)

Snezhnost [94]

Given:

The graph passes through the points (0,-20) and (4,10).

To find:

The equation of line that most closely represents the line depicted in the graph.

Solution:

If a line passing through two points, then the equation of line is

$y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)$

The given line passes through the points (0,-20) and (4,10). So, the equation of line is

$y-(-20)=\dfrac{10-(-20)}{4-0}(x-0)$

$y+20=\dfrac{10+20}{4}(x)$

$y+20=\dfrac{30}{4}x$

$y+20=\dfrac{15}{2}x$

Subtracting 20 from both sides, we get

$y=\dfrac{15}{2}x-20$

The function form is

$f(x)=\dfrac{15}{2}x-20$

f of x equals fifteen halves times x minus 20.

Therefore, the correct option is B.

Solve for L. m=LN+2/K

Iteru [2.4K]

Answer:

$l = \frac{m - \frac{2}{k} }{n} \\ \\$

Step-by-step explanation:

$m = ln + \frac{2}{k} \\ m - \frac{2}{k} = ln \\ \frac{m - \frac{2}{k} }{n} = \frac{ln}{n} \\ l = \frac{m - \frac{2}{k} }{n} \\$

hope this helps
