Désolé pour les erreurs, mais le français n'est pas ma langue maternelle.

Prenant un tiers du temps total, ce qui reste est

1-\dfrac{1}{3}=\dfrac{2}{3}

Si le joueur passe les trois quarts de ce temps à s'échauffer, cela signifie qu'il jouera le dernier quart-temps:

\dfrac{2}{3}\cdot\dfrac{1}{4}=\dfrac{1}{6}

Ainsi, le joueur joue un sixième du temps total.  

Si le match dure 90 minutes, un sixième est 90/6=15 minutes.

Mark the points with the coordinates (4, 14), (22, 6), and (16, 18). Connect the points to form a triangle. and what type of tri
Yakvenalex [24]

Answer:

Step-by-step explanation:

You have  the  points (4, 14), (22, 6), and (16, 18).

It is important to remember that he first number of each point is the x-coordinate of that point and the second number of each one of them is the y-coordinate of that point.

Therefore, knowing the above, you can mark each point, as you can observe in the image attached, and then you can connect the points to form the triangle shown in the image.

Please help ASAP! Will give BRAINLIEST! Please read the question THEN answer correctly! No guessing.
ElenaW [278]

Answer:

x =  -2 ±sqrt(7)

Step-by-step explanation:

3x^2 +12 x = 9

Divide each side by 3

3x^2 /3 +12x/3 = 9/3

x^2 +4x = 3

Take the coefficient of x

4

Divide by 2

4/2 =2

Square it

2^2 =4

Add it to each side

x^2 +4x+4 = 3+4

x^2 +4x+4 = 7

(x+2)^2 = 7

Take the square root of each side

x+2 = ±sqrt(7)

Subtract 2 from each side

x+2-2 = -2 ±sqrt(7)

x =  -2 ±sqrt(7)

Can someone please help me answer this?
Setler79 [48]

Answer:

B

Step-by-step explanation:

If you don't understand some steps, comment it for me please.

1. Find diagonal.

d = 2r

d = 2(9)

d = 18

2. Find length of square.

each length of square = x

x : 18 = 1 : \sqrt{2}

\frac{x}{18} = \frac{1}{\sqrt{2} }

\sqrt{2}x = 18

x = \frac{18}{\sqrt{2} }  = 9\sqrt{2}

3. Find area of circle and square.

Area for circle

A = \pi r^2

A = \pi (9)^2

A = 81\pi = 254.4690...

Area for square

A = (length)^2

A = (9\sqrt{2})^2

A = 162

4. Subtract area of circle to area of square.

254.4690... - 162 = 92.4690...

5. Find the shaded region.

92.4690... / 4 = 23.1172...

Rounded to the nearest hundredth = 23.12
