If nine of every 11 trick-or-treaters that came to your house last Halloween were dressed as pirates what proportion of trick-or-treaters were not dressed as pirates

Step-by-step explanation:

Whenever we put a negative number inside a modulus function it will give us the positive output. For example , |-3| = 3 , |-6|=6, |5|= 5 ,etc.

So a modulus function i.e. |x| is always greater than zero ( positive ) when x is any number except 0 and it is equal to zero when the value of x is 0.

So |x| can't be less than -4 as |x| is always positive . So the statement is false.

The expression |x| < -4 is false because all Positive numbers are greater than all negative numbers.

The modulo of a number x as denoted by; |x| is the positive value of number x irrespective of the value of x.

Hence, the number x, whether positive or negative becomes a positive number and hence;

Answer:

  f(x) = –x^2 – 12x – 36

Step-by-step explanation:

The parent function, x^2, touches the x-axis at x=0. Translating it 6 units left replaces x with x-(-6) = x+6, so the function is ...

  f(x) = (x+6)^2 = x^2 +12x +36

Reflecting the graph across the x-axis doesn't change the x-intercept, so Heather could be writing ...

  f(x) = -x^2 -12x -36

Answer:

x = 6 and y = 2

Step-by-step explanation:

2x + 3y = 18 .......... Eqn 1

3x - 3y = 12 ........... Eqn 2

Add both Equations to eliminate y

we have

2x + 3x + 3y - 3y = 18 + 12

5x = 30

Divide both sides by 5

5x / 5 = 30/5

x = 6

Substitute x = 6 into any of the Equations

Using equation 1

we have

2(6) + 3y = 18

3y = 18 - 12

3y = 6

Divide both sides by 3

That's

3y/3 = 6/3

y = 2

Therefore x = 6 and y = 2

The sides of the regular hexagon ABCDEF can be posed as a. If so, the area of ABCDEF should be 6 times the are of the interior angle in the hexagon, considering there are 6 equilateral triangle that can fit in this regular hexagon,

Area =  6( a * a * sin 60 ) / 2,

Area = ( About ) 2.6 sq units

Now applying cosine for triangle ABC -

AC^2 = AB^2 + BC^2 – ( 2*AB*BC*cos 120 ),

a^2 + a^2 – ( 2a^2 * ( - 0.5 ) ) = a^2 + a^2+a^2 =3a^2,

AC = a√3

The area of ABC should thus be the following -

( a√3 * a√3 * sin 60 )/2 = 1.299038106 sq units

As you can see, the area of ABC is half the area of ABCDEF, thus the ratio of the area of ABC to ABCDEF is 1 : 2

log√(3x) can be written in the expanded form as [tex]\frac{1}{2}[/tex] [log (3) + log (x)].

A logarithm is simply the opposite function of the exponentiation.

It is the exponent to which a number or value is raised to get some other number.

That is, if c = aˣ, then we can write it as x =logₐ c.

We know that,

√a can be written as (a) ^(1/2).

Similarly,

log√(3x) = log (3x)^(1/2)

Now, we have a rule for logarithms that, log aᵇ = b log a.

So,

log√(3x) = log (3x)^(1/2)

              = [tex]\frac{1}{2}[/tex] log (3x)

Using the multiplication rule of logarithms, log (ab) = log (a) + log(b),

              = [tex]\frac{1}{2}[/tex] [log (3) + log (x)]

Hence the expanded form is [tex]\frac{1}{2}[/tex] [log (3) + log (x)].

Answer:

$48, $80

Step-by-step explanation:

$50.88 is the price including tax and the discount. The discount is applied first. Then the tax is applied.

The tax is 6%, so $50.88 is 106% of the discounted price.

$50.88/1.06 = $48

$48 is the discounted price.

The discount is 40% of the original price, so the pre-tax discounted price is 60% of the original price.

$48/0.6 = $80

The original price was $80

10.5cos x=9-4+3.0625

10.5cosx=8.0625

cos x= 8.0625/10.5≈0.77

x≈40 degrees

Answer:  D) 40 degrees

Step-by-step explanation:

Let  A = θ

then a = 2       b = 3     c = 1.75

Use the Law of Cosines:

a² = b² + c² - 2bc · cos A

2² = 3² + 1.75² - 2(3)(1.75) · cos θ

4 = 9 + 3.0625 - 10.5 cos θ

4 = 12.0625 - 10.5 cos θ

The answer is " red cups is "5.25""

Step-by-step explanation:

Given:

red paint= [tex]3\frac{1}{2}= \frac{7}{2} =3.5[/tex]

yellow paint= [tex]4\frac{1}{2}= \frac{9}{2} =4.5[/tex]

total cups=12        

i) The Ratio of red and yellow  is= 3.5 : 4.5

If the red cups are= [tex]\frac{3.5}{8}[/tex]

number of red cups:

[tex]\to \frac{3.5}{8}\times 12\\\\\to \frac{3.5}{2}\times 3\\\\\to 3.5\times 1.5\\\\\to 5.25[/tex]

ii)

[tex]\to 3.5x+4.5x=12......(a)\\\\\to 8x=12\\\to x=\frac{12}{8}\\\\\to x=\frac{3}{2}\\\\[/tex]

put the value of x in equation (a):

[tex]\to 3.5 \times \frac{3}{2}+4.5\times \frac{3}{2}=12\\\\\to 35 \times \frac{3}{20}+45\times \frac{3}{20}=12\\\\\to 5.25+6.75=12[/tex]

iii)

if [tex]\frac{4.5}{8} \times 12= 6.75[/tex] yellow cups used in making orange paint

so, red paint +yellow paint = total cups

let, red paint cups =x

⇒x+6.75=12

⇒x=12-6.75

⇒x=5.25

The value of red cups is 5.25.

Answer:

23.14

Step-by-step explanation:

Solve for the area of the figure by dividing it up into parts.  You can divide into a half-circle and a triangle

Half-Circle

The diameter is 6.  This means that the radius is 3.  Use the formula for area of a circle.  Divide the answer by two since you only have a half-circle.

A = πr²

A = π(3)²

A = 9π

A = 28.274

28.274/2 = 14.137

Triangle

The base is 3 and the height 6.  Use the formula for area of a triangle.

A = 1/2bh

A = 1/2(6)(3)

A = 3(3)

A = 9

Add the two areas together.

14.137 + 9 = 23.137 ≈ 23.14

The area is 23.14.

Answer:

Step-by-step explanation:

The figure consists of a semi circle and a triangle

Area of the figure = Area of semi circle + Area of triangle

Area of semi circle is 1/2πr²

where r is the radius

radius = diameter/2

radius = 6/2 = 3

Area of semi circle is

1/2π(3)²

1/2×9π

14.14 sq. units

Area of a triangle is 1/2×b×h

h is the height

b is the base

h is 6

b is 3

Area of triangle is

1/2×3×6

9 sq. units

Area of figure is

14.14 + 9

= 23.14

Which is 23 sq. units to the nearest hundredth

Answer:

5 5/12 cups

Step-by-step explanation:

Answer:

B.

Step-by-step explanation:

First, notice that we can cancel out an x in the second term. Thus:

[tex]\displaystyle \frac{3x^2}{x^2+x} =\frac{3x^2}{x(x+1)} =\frac{3x}{x+1}[/tex]

As with the last question, change the sign to multiplication and "flip" the second term:

[tex]\displaystyle \frac{2x-1}{x+1}\cdot \frac{x+1}{3x}[/tex]

Multiply straight across:

[tex]\displaystyle =\frac{(2x-1)(x+1)}{(x+1)(3x)}[/tex]

We can cancel the (x + 1) term:

[tex]\displaystyle =\frac{2x-1}{3x}[/tex]

This cannot be simplified further. Hence, our answer is B.
