Answer:

79%

Step-by-step explanation:

Area of rectangular region = 3*6 = 18 sq inches

Diameter of circle = 3 in

-> radius (r) = 3/2 = 1.5 inches

[tex]Area \: of\:both \: circular \: regions \\ =2( \pi {r}^{2} ) \\ =2( 3.14 \times {1.5}^{2} ) \\ = 14.13 \: {in}^{2} \\ \\ P(dart \: landing \: in \: the \: shaded \: area) \\ = \frac{Area \: of \: both \: circular \: regions}{Area \: of \: rectangular \: region} \\ = \frac{14.13}{18} \\ = 0.785 \\ \approx \: 0.79\\=79\%[/tex]

Answer:

6,138

Step-by-step explanation:

Given the following:

Vocalist needed :

First day (a) = 6

For subsequent days : number doubles

Using the relation. :

Sn = a(r^n -1)/(r -1)

Where a = first term = 6

r = common ratio = r3/r2 = r4/r3

Since number doubles after each consecutive day, then ; r = 2, n = 10

Sn = 6(2^10 -1)/(2 -1)

Sn = 6(1024 - 1) / 1

Sn = 6144 - 6

Sn = 6138

Answer:

x = 20

Step-by-step explanation:

these are alternate interior angles, which means they're equal.

you can use that information to make this equation:

x + 40 = 3x

subtract x from both sides

40 = 2x

divide both sides by 2

20 = x

The exponential function is given by y = 13000(0.85)ˣ, the amount of rats in 3 years is 7984

An exponential function is in the form:

y = abˣ

Where y,x are variables, a is the initial value of y and b is the multiplication factor.

Let y represent the population of the chicken after x year.

The initial population of 13000 rats, hence a = 13000

The rat population declining by 15% every year. b = 1 - 0.15 = 0.85

The exponential function is given by y = 13000(0.85)ˣ

In 3 years; y = 13000(0.85)³ = 7984

The exponential function is given by y = 13000(0.85)ˣ, the amount of rats in 3 years is 7984

The central angle (127 degrees) is the angle at point K

The measures of JL and JML are 127 and 233 degrees, respectively

From the complete question, we have:

JL = 127 degrees.

The sum of angles at a point is 360 degrees

So, we have:

JML + 127 = 360

Subtract 127 from both sides

JML = 233

Hence, the measures of JL and JML are 127 and 233 degrees, respectively

Answer:

Step-by-step explanation:

Dado que la longitud, la profundidad y la altura de un cubo son iguales, podemos acortar el proceso elevando al cubo cualquiera de estas medidas. Sigamos con el ejemplo. Dado que la longitud de cualquier arista de este cubo es de 5 cm (2 pulgadas), podemos hallar el volumen multiplicando 5 x 5 x 5 (o 53) = 125.

[tex]\\ \rm\Rrightarrow \sqrt{9-4\sqrt{5}}+\sqrt{5}[/tex]

[tex]\\ \rm\Rrightarrow \sqrt{9-8.8}+2.2[/tex]

[tex]\\ \rm\Rrightarrow \sqrt{0.2}+2.2[/tex]

[tex]\\ \rm\Rrightarrow 0.3+2.2[/tex]

[tex]\\ \rm\Rrightarrow 2.5[/tex]

[tex]\\ \rm\Rrightarrow 2(approx)[/tex]

Answer:

Algebraic "proof" that the solution is 2:

[tex]\sqrt{9-4\sqrt{5} }\:+\sqrt{5}[/tex]

[tex]=\sqrt{4-4\sqrt{5}+5 }\:+\sqrt{5}[/tex]

[tex]=\sqrt{2^2-4\sqrt{5}+(\sqrt{5})^2 }\:+\sqrt{5}[/tex]

[tex]=\sqrt{(2-\sqrt{5})^2 }\:+\sqrt{5}[/tex]

[tex]=(2-\sqrt{5})+\sqrt{5}[/tex]

[tex]=2[/tex]

However, this is not the correct mathematical solution to the problem.

The order of operations for [tex]\sqrt{(2-\sqrt{5})^2 }[/tex] dictate that the operation inside the parentheses must be carried out first.  

As [tex]2-\sqrt{5} < 0[/tex], then [tex](2-\sqrt{5})^2[/tex] will always be positive.

If  [tex](2-\sqrt{5})^2[/tex] is always positive, then [tex]\sqrt{(2-\sqrt{5})^2 }[/tex] will always be positive.

As √5 > 2 and [tex]\sqrt{(2-\sqrt{5})^2 } > 0[/tex] then [tex]\sqrt{(2-\sqrt{5})^2 }\:+\sqrt{5} > 2[/tex]

So mathematically, the actual solution to the expression is 2.47 (nearest hundredth) not 2.

Answer:

1/64

Step-by-step explanation:

A negative exponent in essence brings your 2^6 value under 1. So your problem would now look like 1/(2^6). From there it is easy simplifying, knowing hat 2^6 = 64. So your answer turns out to be 1/64.

2 to the power minus 6 as a fraction would be equal to 1/64

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

A negative exponent in essence brings  2^6 value under 1.

So  1/(2^6).

From there it is easy simplifying, knowing that;

2^6 = 64.

Therefore, the answer turns out to be 1/64.

2 to the power minus 6 as a fraction would be equal to 1/64

#SPJ2

Step-by-step explanation:

Use the systematic new AC Method to factor trinomials (Socratic Search)

y

=3x2+7x−6

=3(x + p)(x + q)

Converted trinomial:

y'

=x^2+7x−18

= (x + p')(x + q').

p' and q' have opposite signs.

Factor pairs of (ac = -18) --> (-2, 9). This sum is 7 = b. Then p' = -2 and q' = 9. Therefore,

p ='p/a

= -2/3

and

q ='q/a

=9/3

=3.

Factored form: y = 3(x - 2/3)(x + 3) = (3x - 2)(x + 3)
