Answer: The correct option is

(c) $\dfrac{RQ}{PQ}.$

Step-by-step explanation: We are given a right-angled triangle PQR, with m∠R = 90°, m∠Q = 60° and m∠P = 30°.

We are to select the ratio that represents sin P.

We know that sine of any acute angles is the ratio of the length of the perpendicular to the length of the hypotenuse.

For the acute angle P, we have

perpendicular = RQ and hypotenuse = PQ.

Therefore, we get

$\sin P=\dfrac{perpendicualr}{hypotenuse}\\\\\\\Rightarrow \sin P=\dfrac{RQ}{PQ}.$

Thus, (c) is the correct option.

Answer: 31 and 1/9

Step-by-step explanation:

d =29, for g=16,h=9

replace values of each number in equati/on:

d+g/h=29+19/9=(9*29+19)/9=( 261+19)/9=280/9= 31 and 1/9

Answer:

$x=\frac{7}{15}$

Step-by-step explanation:

$5x-\frac{1}{5} =\frac{7}{3}$

$5x - \frac{3}{15} = \frac{35}{15}$

$5x - \frac{3}{15} + \frac{3}{15} = \frac{35}{15} + \frac{3}{15}$

$5x=\frac{35}{15}$

$\frac{5x}{5} } =\frac{\frac{35}{15}}{5}$

$x=\frac{7}{15}$

WILL MARK BRAINLIEST!!! HELP!

Virty [35]

Answer:

d) x=4

Step-by-step explanation:

$\sqrt{x} +5 = \sqrt{x + 45}$

$(\sqrt{x} +5)^{2} = (\sqrt{x + 45})^{2}$

$x + 10\sqrt{x} +25 = x + 45$

$10\sqrt{x} = 20$

divide 10 in both sides

$(\sqrt{x}){2} = (2){2}$

x=4

The answer and how to do it.

Kruka [31]

let x = orginal price of the shorts

$21 = x(100%-20%) * 1.05

$21 = x(80%) * 1.05

$21 = 0.8x * 1.05

Subtract 1.05 from both sides

$19.95 = 0.8x

Divide 0.8 from both sides

$24.9375 = x

So the orginal price of the shorts are about $24.94

50 POINTS AND BRAINIEST PLEASE HELP

exis [7]

Answer:

Step-by-step explanation:

If you notice very carefully then you will see that the line passes through the points :

( 1 , - 2 )

( - 1 , 2 )

Hence the value of x = 1 when the value of y = - 2 .

We know that - 2 × 1 = - 2

⇒ - 2 x = y

⇒ y = - 2x

Hence the first OPTION is correct .

Verification :

For points ( - 1 , 2 ) we can write :

y = - 2x

⇒ 2 = - 2 × - 1

⇒ 2 = 2

Hence the answer is verified .

Always try to use the converse of the graphical method .

( Nothing converse is there ... just saying the opposite steps of that method :P )

I mean in graphical method we plot points and then join , here identify the joined points and then make the equation .
