7 0

Answer:

Step-by-step explanation:

In a pen there are 200 animals,

25 of which are ducks,

Number of turkeys

50% are turkeys

= 50% × 200

= 100 turkeys

and

Numbers of chickens

75% are chickens.

= 75% × 200

= 150

How many animals are ducks, turkeys and chickens?

What is the center and radius of x^2+6x+y^2-4y =-4?

Nat2105 [25]

Answer:

The center of this circle is at $(-3,\, 2)$ . The radius of this circle is $3$ .

Step-by-step explanation:

A circle with center $(a,\, b)$ and a radius of $r$ ( $r > 0$ ) could be expressed as:

$(x - a)^{2} + (y - b)^{2} = r^{2}$ .

(In other words, a point is on this circle if and only if the distance between that point and the center is equal to the radius.)

Rearrange this equation using binomial expansion to match the equation given in this question:

$(x^{2} - 2\, a\, x + a^{2}) + (y^{2} - 2\, b\, y + b^{2}) = r^{2}$ .

$x^{2} + (-2\, a)\, x + y^{2} + (-2\, b)\, y = -a^{2} - b^{2} + r^{2}$ .

The equation in this question is:

$x^{2} + 6\, x + y^{2} + (-4)\, y = -4$ .

Match up the coefficients of $x$ and $y$ in the two equations.:

Coefficient of $x$ : $(-2\, a) = 6$ .
Coefficient of $y$ : $(-2\, b) = (-4)$ .

Thus, $a = (-3)$ and $b = 2$ .

The constants of the two equations should also match up:

$(-a^{2} - b^{2} + r^{2}) = (-4)$ .

Substitute in $a = (-3)$ as well as $b = 2$ and solve for $r$ :

$r^{2} = 9$ .

$r = 3$ (since $r > 0$ .)

Therefore, the center of this circle is $(-3,\, 2)$ . The radius of this circle is $3$ .

PLEASE HURRY IM TIMED!!!

<u>Answer-</u>

<em>A. Brandon’s sound intensity level is 1/4th as compared to Ahmad’s.</em>

<u>Solution-</u>

Given that, loudness measured in dB is

$L=10\log \frac{I}{I_0}$

Where,

I = Sound intensity,

I₀ = 10⁻¹² and is the least intense sound a human ear can hear

Given in the question,

I₁ = Intensity at Brandon's = 10⁻¹⁰

I₂ = Intensity at Ahmad's = 10⁻⁴

Then,

$L_1=10\log \frac{I_1}{I_0}=10\log \frac{10^{-10}}{10^{-12}}=10\log \frac{1}{10^{-2}}=10\log 10^{2}=2\times10\log 10=20$

$L_2=10\log \frac{I_2}{I_0}=10\log \frac{10^{-4}}{10^{-12}}=10\log \frac{1}{10^{-8}}=10\log 10^{8}=8\times10\log 10=80$

$\therefore \frac{L_1}{L_2} =\frac{20}{80} =\frac{1}{4}$

Among 21- to 25-year-olds, 29% say they have driven while under the influence of alcohol. Suppose that three 21- to 25-year-olds

Sophie [7]

Answer:

P(3) = 0.0244

P(3) = 2.44%

the probability that all three selected have driven while under the influence of alcohol is 2.44% or 0.0244

Step-by-step explanation:

Given;

The probability that they have driven while under the influence of alcohol is;

P = 29% = 0.29

the probability that all three selected have driven while under the influence of alcohol is;

P(3) = P × P × P

P(3) = 0.29 × 0.29 × 0.29

P(3) = 0.024389

P(3) = 0.0244

P(3) = 2.44%

the probability that all three selected have driven while under the influence of alcohol is 2.44% or 0.0244

Enter number as an integer or decimal.

Strike441 [17]

Answer:

$x$

Step-by-step explanation:

$30-4x>6x-10$

Adding 10 to both sides.

$10+30-4x>6x-10+10$

$40-4x>6x$

Adding $4x$ to both sides.

$4x+40-4x>6x+4x$

$40>10x$

Dividing both sides by 10.

$\frac{40}{10}>\frac{10x}{10}$

$4>x$

∴ $x$
