First, we want to convert 600 feet to inches:

600 feet (12 inches/ft) = 7200 inches

We know that the diameter is 60 inches, so the circumference is 60π inches or 188.5 inches.
We can divide 7200/188.5 to get about 38.2 rotations.

Determine the value of B such that the line defined by 8x + By + 92 = 0 passes through the point (-4,12).

zvonat [6]

8x + By + 92 = 0

(-4; 12) ⇒ x = -4; y = 12

subtitute

8 · (-4) + 12B + 92 = 0
-32 + 12B + 92 = 0
12B + 60 = 0 |subtract 60 from both sides
12B = -60 |divide both sides by 12

B = -5

Solve the quadratic equation below for the exact values of x:<br> 4x^2-5=75

grandymaker [24]

Step-by-step explanation:

$4 {x}^{2} - 5 = 75 \\ 4 {x}^{2} = 75 + 5 \\ 4 {x}^{2} = 80 \\ {x}^{2} = \frac{80}{4} \\ {x}^{2} = 20 \\ x = \pm \sqrt{20} \\ x = \pm 2 \sqrt{5}$

In the game of Pick-A-Ball, there are 10 colored balls: 2 red, 4 white, and 4 blue. The balls have been placed into a small buck

MaRussiya [10]

Answer:

The probability of selecting the color of ball that you just selected(a red ball) is $P(r) = \frac{2}{10}$

Step-by-step explanation:

From the question we are told that

The total number of colored balls is n = 10

The number of red balls is r = 2 red

The number of white ball is w = 4

The number of blue balls is b = 4

The number of balls to be selected is N = 2 balls

The cost of playing picking a ball is c = $10

The winnings is $k = \$ P(A)$

Here P(A) is the probability of obtaining the exact sequence of result and from the question it is P(A) = 0.10

Generally my price according to the question is

$k = \frac{0.10 }{10}$

=> $k = 0.01$

Let assume we selected a red ball

Generally the probability of selecting a red ball is mathematically represented as

$P(r) = \frac{2}{10}$
