Refer to the picture above

vodomira [7]

Answer:

3.14

Step-by-step explanation:

First find the circumference of the circle:

$2\pi r$ = Circumference.

$2 * \pi * 6$ = $12\pi$

Find the ratio of the angle in relation to the entire circle:

$30^o$ is what we have. So:

$\frac{30^o}{360^o} = \frac{1}{12}$

Use the ratio and multiply the circumference to find the length:

$12\pi * \frac{1}{12}$ = $\pi$

Round answer to the hundredth:

$\pi = 3.14$

Segments RT and SU are diameters of circle O.What is mSRT?

Pavlova-9 [17]

Angle SRT is undetermined by the question.

A diameter always subtends a right angle (Thales' Theorem, the first in geometry) so we can be assured SRU, STU, RUT and RST are right angles.

Find the slope of the line passing through the points D (10, 8) and E (-4,4)

RUDIKE [14]

Answer:

Slope=2/7

Step-by-step explanation:

Slope=rise/run

$rise = 8 - 4 = 4 \\ run = 10 - ( - 4) = 14 \\ slope = \frac{4}{14} = \frac{2}{7}$

Dustin has a bag of marbles with 4 blue marbles, 4 white marbles, and 3 red marbles.

diamong [38]

Answer:

A.

$\dfrac{6}{55}$

B.

$\dfrac{6}{55}$

C.

$\dfrac{4}{165}$

Step-by-step explanation:

Dustin has a bag of marbles with 4 blue marbles, 4 white marbles, and 3 red marbles. There are 11 marbles in total.

A. The probability that the first marble drawn is blue marble is

$\dfrac{4}{11},$

the probability that the second marble drawn is red marble is

$\dfrac{3}{10}$

The probability that the first marble drawn is blue and the second is red is

$\dfrac{4}{11}\cdot \dfrac{3}{10}=\dfrac{12}{110}=\dfrac{6}{55}$

B. The probability that the first marble drawn is red marble is

$\dfrac{3}{11},$

the probability that the second marble drawn is white marble is

$\dfrac{4}{10}$

The probability that the first marble drawn is red and the second is white is

$\dfrac{3}{11}\cdot \dfrac{4}{10}=\dfrac{12}{110}=\dfrac{6}{55}$

C. The probability that the first marble drawn is blue marble is

$\dfrac{4}{11},$

the probability that the second marble drawn is blue marble is

$\dfrac{3}{10},$

the probability that the third marble drawn is blue marble is

$\dfrac{2}{9},$

The probability that the first, second and third marbles drawn are blue is

$\dfrac{4}{11}\cdot \dfrac{3}{10}\cdot \dfrac{2}{9}=\dfrac{24}{990}=\dfrac{4}{165}$
