Answer:

Step-by-step explanation:

Given that:

Fraction with brown hair = 2 /5

1/4 of brown haired girls have long hairs

2/3 of long, brown haired girls have green eyes.

Fraction of girls with long, brown hair :

1/4 of 2/5

1/4 * 2/5 = (1*2) / (4*5) = 2/ 20 = 1/10

Fraction with long, brown hair and green eyes :

2/3 of Fraction with long, brown hair :

2/3 of 1/10

2/3 * 1/10 = (2*1) / (3*10) = 2/30 = 1/15

Two sides of a triangle measure 9 centimeters and 37 centimeters what could the length of the third triangle?
STALIN [3.7K]

Step-by-step explanation:

One side of a triangle is 9 cm and other side is 37 cm. We need to find what could be the length of the third side of the triangle.

If we add one and other side i.e. 9 cm + 37 cm = 46 cm

If we subtract one and other side i.e. 37 cm - 9 cm = 28 cm

We know that, the length of the third side must be less than the sum of the other two sides and greater than the difference between the other two sides.

Thus, the third side could be between 46 cm and 28 cm.

A triangle has a 60° angle, and the two adjacent sides are 12 and "12 times the square root of 3". Find the radius of a circle w
shusha [124]

The radius of a circle with the same vertex as a center is 12 units

<h3>Application of Pythagoras theorem;</h3>

To get the radius of the circle, we need to determine the diameter of the circle first:

According to SOH CAH TOA:

sin\theta = \frac{opp}{hyp} \\sin60 = \frac{12\sqrt{3}}{hyp} \\hyp =\frac{12\sqrt{3}}{sin60} \\hyp =\frac{2\times12\sqrt{3}}{\sqrt3}} \\hyp = 24 = diameter

Determine the radius of the circle

Radius = dismeter/2

Radius = 24/2

Radius = 12

Hence the radius of a circle with the same vertex as a center is 12 units
