Answer:

16/25 = 0.64

Step-by-step explanation:

18 rolls are ones, so 32 rolls are not ones.

The experimental probability is 32/50 = 16/25 = 0.64.

Find the area and the circumference of a circle with diameter 9 yards using the value 3.14 for pi
Ray Of Light [21]
Area of circle = pi r^, (r)radius is half the diameter so 9÷2=4.5 so in this scenario it would be 3.14×4.5^
3.14×4.5×4.5=63.6

circumference of circle= diameter×pi (3.14)
so 9×3.14=28.3

Solve the rational equation (3x^2+1)/(x-1) + x =4 + 4/(x-1)
natita [175]

Answer:

The answer to your question is letter D

Step-by-step explanation:

Rational equation

                               \frac{3x^{2} + 1}{x - 1} + x = 4 + \frac{4}{x - 1}

Simplify

                             \frac{3x^{2} + 1 + x(x - 1)}{x - 1} = \frac{4(x - 1) + 4}{x - 1}

Cancel the denominators and expand

                            3x² + 1 + x² - x = 4x - 4 + 4

Simplify                                              

                            4x² - x + 1 - 4x = 0

                            4x² - 5x + 1 = 0

Factor

                            4x² - 4x - 1x + 1 = 0

                            4x(x - 1) - 1(x - 1) = 0

                             (4x - 1)(x - 1) = 0

                            x₁ = 1/4        x₂ = 1
