Answer:

36.1 meters

Step-by-step explanation:

Since this is a rectangle, the parallel sides are equal to each other, meaning we technically already know all the side lengths.

I'll choose to look at the bottom triangle in this case

30 is already there, and the other leg should be 20. Knowing this, we can plug these into the pythagorean theorem.

20 is A, 30 is B, and the missing side is C

[tex]a^{2} + b^{2} = c^{2}\\20^{2} + 30^{2} = c^{2} \\400 + 900 = 1300 \\\sqrt{1300} = 36.06\\[/tex]

C, the missing side to the nearest tenth is 36.1 meters

Answer:

Step-by-step explanation:

From the given information;

Let R represent Ramadan Inn

S to represent Sheraton; &

L to represent Lakeview Motor

F to represent faulty plumbing

So;

P(R) = 0.2

P(S) = 0.5

P(L) = 0.3

P(F|R) = 0.05

P(F|S) = 0.04

P(F|L) = 0.08

Then; to find the probability there will be a client assigned to the faulty room.

i.e.

P(F) =( P(R) × P(F|R) ) + ( P(S) × P(F|S) ) + ( P(L) × P(F|L) )

P(F) = (0.2 × 0.05) + (0.5 × 0.04) + (0.3 × 0.08)

P(F) = 0.01 + 0.02 + 0.024

P(F) = 0.054

suppose an individual with a room possessing faulty plumbing was given an accomodation at Lakeview Motor

Then:

P(L|F) = P(L) × P(L|F) / P(F)

P(L|F) = 0.3 × 0.08 / 0.054

P(L|F) = 0.4444

   [tex]h^{l} (s) = \frac{1 }{(\sqrt{s}) (1-\sqrt{s})^{2} }[/tex]

Step-by-step explanation:

Explanation

Given that

          [tex]h(s) = \frac{1+\sqrt{s} }{1-\sqrt{s} }[/tex]

Differentiating equation (i) with respective to 'x'  ,we get

       [tex]h^{l} (s) =\frac{1-\sqrt{s}) \frac{1}{2\sqrt{s} } -(1+\sqrt{s})(\frac{-1}{2\sqrt{s} )} }{(1-\sqrt{s})^{2} }[/tex]

      [tex]h^{l} (s) = \frac{\frac{1}{2\sqrt{s} } -\frac{1}{2\sqrt{s} }X\sqrt{s} + \frac{1}{2\sqrt{s} } +\frac{1}{2\sqrt{s} }X\sqrt{s} }{(1-\sqrt{s})^{2} }[/tex]

      [tex]h^{l} (s) = \frac{\frac{2}{2\sqrt{s} } }{(1-\sqrt{s})^{2} }[/tex]

     [tex]h^{l} (s) = \frac{1 }{(\sqrt{s}) (1-\sqrt{s})^{2} }[/tex]

Answer:

Substitute the value of the variable into the equation and simplify.

Answer:  (i) This angle is 33.41% of the full rotation.

(ii) 120.38°

Step-by-step explanation:

GIven: Measure of full rotation = 2π radians

Measure of an angle = 2.1 radians.

The percent of this angles of a full rotation = [tex]\dfrac{2.1}{2\pi}\times100\%[/tex]

[tex]=\dfrac{2.1\times7}{2\times22}\times100\% \ \ \ \ [\pi =\dfrac{22}{7}]\\\\=33.41\%[/tex]

i.e. This angle is 33.41% of the full rotation.

In degrees,

[tex]\text{ 2.1 radians}=2.1\times\dfrac{180}{\pi}\\\\=2.1\times\dfrac{180}{3.14}\approx120.38^{\circ}[/tex]

[tex]2.1\text{ radians}[/tex] is [tex]33.4\%[/tex] of a full rotation and is equivalent to [tex]120.2^\circ[/tex]

The relationship between degree and radian measures is

[tex]1\text{ radian}=\dfrac{180}{\pi}^\circ[/tex]

We want to express [tex]2.1\text{ radians}[/tex] as a percentage of a full rotation.

[tex]\dfrac{2.1}{2\pi}\times100\%=\dfrac{210}{2\pi}\%\\\\\approx33.4\%[/tex]

How do we determine the measure of an angle (in degrees) given the percentage? Simply multiply the percentage by the complete/full rotation (that is [tex]360^\circ[/tex])

[tex]33.4\%\times360^\circ\\\\=\dfrac{33.4}{100}\times360^\circ\\\\\approx120.2^\circ[/tex]

Answer:

He paid 17% of the bill as a tip.

Step-by-step explanation:

Paid $35.75 for dinner at a restaurant, plus an additional $7.15 tip.

So in all, he paid 35.75 + 7.15 = $42.9

Tip as a percent:

Tip(7.15) multiplied by 100 and divided by the total(42.9). So

7.15*100/42.9 = 16.7%

Rounded to the nearest percent

He paid 17% of the bill as a tip.

Answer: a slice of pizza cost $1.25 and a 12-ounce cola cost $0.50.

Step-by-step explanation:

Let slice of pizza cost x and a 12-ounce cola cost y.

Then Sara's order cost: 2x+y=3

and Sydney's order cost: 3x+2y=4.75

From the first equation we have: y=3-2x and put this to the second equation:

3x+2(3-2x)=4.75

3x+6-4x=4.75

x=1.25

y=3-1.25*2=0.50

Answer: a slice of pizza cost $1.25 and a 12-ounce cola cost $0.50.

Answer:

[tex]y=\frac{1}{4}x+1[/tex]

Step-by-step explanation:

the common formula of the required equation is:

[tex]\frac{x-X_A}{X_B-X_A} =\frac{y-Y_A}{Y_B-Y_A};[/tex]

if to substitute the given coordinates into the folmula above, then the required equation is:
