There are 3 urns A, B and C each containing a total of 10 marbles of which 2, 7 and 4 respectively are red. One of the urns is s

<h3>Answer: 7/13</h3>

======================================================

Explanation:

We know that the marble selected is red, so we don't need to focus on the other colors.

7 red marbles are in urn B out of 2+7+4 = 13 total red marbles.

The probability the red marble came from urn B is therefore 7/13

Describe a real-world situation that is a model by multiplying two fractions or mixed numbers

Ivanshal [37]

Construction.

When construction workers need measurements that are fractions they need to be able to multiply/add/subtract/divide all of those different fractions and mixed numbers.

I hope I was able to help. Best of luck.

Since you have the 42-deg angle and the length of the opposite side, 31, you can use the Law of Sines.

$\dfrac{a}{\sin A} = \dfrac{b}{\sin B} = \dfrac{c}{\sin C}$

We will use the law of sines first to find x.

Once we know x, we can find the angle opposite y.

Then we can find y.

$\dfrac{31}{\sin 42^\circ} = \dfrac{37}{\sin x}$

$\sin x = \dfrac{37\sin 42^\circ}{31}$

$\sin x = 0.798639$

$x = \sin^{-1} 0.798639 = 53^\circ$

Let z = the angle opposite y.

z + 42 + 53 = 180

z = 85

$\dfrac{31}{\sin 42^\circ} = \dfrac{y}{\sin 85^\circ}$

$y = \dfrac{31 \sin 85^\circ}{\sin 42^\circ}$

$y = 46.2$

Find an equation of the circle that has center (- 6, 5) and passes through (- 1, 1) .

dangina [55]

Answer:

$(x+6)^2+(y-5)^2=41$

Step-by-step explanation:

The equation of a circle follows the general equation $(x - h)^2 + (y - k)^2 = r^2$

Since the center of the circle is (-6, 5), we progress to the formula equation $(x + 6)^2 + (y- 5)^2 = r^2$

Since this is a circle, the distance between (-6, 5) and (-1, 1) is the radius of the circle.

$r = \sqrt{(-6 + 1)^2 + (5 - 1)^2} = \sqrt{5^2+4^2}=\sqrt{41}\\\\r^2 = 41$

So we can obtain the equation $(x+6)^2+(y-5)^2=41$
