The ratio of red beads to blue beads on a necklace is 4:7. What fraction of the beads are blue?

Answer:

0.006 is the larger decimal

Answer:

0.006 is the right answer

Step-by-step explanation:

Since (0.006) has the least amount of zeros after the decimal, it would be larger than the other decimal that has more zeros after the decimal.

Answer:

x = 4/7

Step-by-step explanation:

x^3 = 64/ 343 // - 64/ 343

x^3 - ( 64/ 343 ) = 0

x^3 - 64 / 343 = 0

1*x^3 = 64/ 343 // : 1

x^3 = 64/ 343

x^3 = 64/ 343 // ^ 1/3

x = 4/ 7

In order for two complex numbers to be equal, their real and imaginary parts must match up.

So if

x ² + 2xy + i (y - 1) = x ² - 2x + 2y - i (x + y)

then

x ² + 2xy = x ² - 2x + 2y

and

y - 1 = -x - y

Solve for x and y : the first equation gives

x ² + 2xy = x ² - 2x + 2y

2xy = 2y - 2x

and the second gives

y - 1 = -x - y

2y = 1 - x

Substitute this into the first equation:

x (1 - x) = (1 - x) - 2x

x - x ² = 1 - 3x

x ² - 4x + 1 = 0

x = 2 ± √3

Then

x = 2 - √3   ==>   y = (-1 + √3)/2

x = 2 + √3   ==>   y = (-1 - √3)/2

both of which make both sides of the equation (2 - √3) + i (√3 - 3)/2.

From the density in the diagram, the probability that X is between 0.5 and 1.5 is 1/2. Option B

The probability density function of a random variable X is a function that gives the probability that X will take on a certain value.

In this case, the probability density function is a line segment that goes from 0 to 1.

The probability that X is between 0.5 and 1.5 is the area under the probability density function between 0.5 and 1.5.

This area is equal to the length of the line segment between 0.5 and 1.5, which is 1.

Therefore, the probability that X is between 0.5 and 1.5 is 1/2. Option B

h(x) =

Step-by-step explanation:

The area of the quadrilateral with the given coordinates is 27 square units.

The coordinates of the quadrilateral are A(0, 4), B(5, 2), C(3, -3) and D(-2, -1).

We need to find the area of the quadrilateral with the given coordinates.

The formula to find the area of the quadrilateral with coordinates ( x₀, y₀ ), ( x₁, y₁ ), ( x₂, y₂ ), ( x₃, y₃ ) is (1/2) × ( x₀y₁ - x₁y₀ + x₁y₂ - x₂y₁ + x₂y₃ - x₃y₂ + x₃y₀ - x₀y₃ ).

Now, Area=1/2×(0×2-5×4+5×(-3)-3×2+3×(-1)-(-2)×(-3)+(-2)×4-0×(-1))

=1/2×|(-20-15-6-3-6-8)|=27 square units.

Therefore, the area of the quadrilateral with the given coordinates is 27 square units.

Answer:

r = 9

Step-by-step explanation:

These are vertical angles, therefore, the measurements is the same. Set the two measurements equal to each other:

7r - 5 = 6r + 4

Isolate the variable, r. Note the equal sign, what you do to one side, you do to the other. Add 5 and subtract 6r from both sides of the equation:

7r (-6r) - 5 (+5) = 6r (-6r) + 4 (+5)

7r - 6r = 4 + 5

Simplify:

7r - 6r = 4 + 5

r = 9

9 is your value for r.

Answer:

  $2089

Step-by-step explanation:

One way to do this rounding is to add $0.50, then drop all of the fractional digits.

  $2088.523125 + 0.50 = $2089.023125

Dropping all of the digits right of the decimal point gives $2089.

Answer:

H = (n/4v) - c

Step-by-step explanation:

I ASSUME the equation is

v = n/(4(c + H))

multiply by (c + H)

v(c + H) = n/4

divide by v

c + H = n/4v

subtract c

H = (n/4v) - c

If the equation is v = (n/4)(c + H)

Then

H = (4v/n) - c
