What is 1/2 divided by 3?

Answer:

Step-by-step explanation:

[tex]S = 1/2, 1, 3/2, 4, 5/2, 3, 7/2...\\a_n = \frac{n}{2}\\a_{15} = \frac{15}{2}[/tex]

Answer:

[tex]4x[/tex]

Step-by-step explanation:

We want to find the simplest rational exponent form of

[tex]\sqrt{x} \cdot 4\sqrt{x}[/tex]

Recall that: [tex]\sqrt{a}=a^{\frac{1}{2} }[/tex]

We rewrite the expression in the exponent form to get:

[tex]x^{\frac{1}{2}}\cdot 4x^{\frac{1}{2}[/tex]

We can regroup the product to get:

[tex]4 x^{\frac{1}{2}\cdot x^{\frac{1}{2}[/tex]

We apply the rule: [tex]a^m\cdot a^n=a6{m+n}[/tex] to get:

[tex]4 x^{\frac{1}{2}}\cdot x^{\frac{1}{2}=4 x^{\frac{1}{2}+\frac{1}{2}}[/tex]

[tex]4 x^{\frac{1}{2}}\cdot x^{\frac{1}{2}=4 x^{1}[/tex]

[tex]4 x^{\frac{1}{2}}\cdot x^{\frac{1}{2}=4x[/tex]

[tex]P=\frac{10}{3} (72)\\P=240[/tex]

Answer:

40°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the 2 given angles from 180 for third angle

third angle = 180° - (90 + 50)° = 180° - 140° = 40°

Answer: B. 40

Step-by-step explanation: A triangle’s angles will always add up to 180 degrees. Add the 2 angles that are given. 90 + 50 = 140. Subtract this number from 180. 180 - 140 = 40. The third angle is 40 degrees.

To work out the central angle, you just re-arrange the equation for the length of an arc:

Equation for length of an arc:

[tex]\frac{angle}{360}[/tex] × [tex]diameter[/tex] × π = [tex]length of arc[/tex]

We can arrange this to work out the central angle, q.  But first, lets substitute in all of the values that we know:

angle = q

diameter = 5 x 2 = 10 ft

length of arc = 7

[Substitute in]

[tex]\frac{q}{360}[/tex] × [tex]10[/tex]π = [tex]7[/tex]       (Now just rearrange for q)

[tex]\frac{q}{360}[/tex] = [tex]\frac{7}{10\pi }[/tex]     (multiply both sides by 360 to get q)

[tex]q[/tex] = [tex]\frac{7}{10\pi }[/tex] × [tex]360[/tex]  (now just simplify)

[tex]q[/tex] = [tex]\frac{252}{\pi }[/tex]

   = [tex]80.214[/tex]   (rounded to 3 decimal places)

______________________________

Therefore:

The equation that gives you ange q is:

[tex]q[/tex] = [tex]\frac{length.of.arc}{diamater.times.\pi }[/tex] × [tex]360[/tex]

and q = 80.214  when all of the values are substituted in.

Answer:

B q=7/5

Step-by-step explanation:

Well Q=s/r and they said a Radius of 5 Which puts 5 at the bottom.

Then an arc length of 7 Which =S. so q=7/5

Complementary angle add up to 90 degrees.

Angle A = x + 6

Angle B = x

They both add up to 90.

x + 6 + x = 90

2x + 6 = 90

2x = 90 - 6

2x = 84

x = 84/2

x = 42

Angle A = x + 6

Angle A = 42 + 6

Angle A = 48 degrees

The correct answer is c. 1-2 sin^2 x.

The correct answer is c. 1-2 sin^2 x.

To find the value of sin 2x, we can use the double angle formula for sine, which states that sin 2x = 2sin x cos x. Therefore, b. 2 sin x cos x is the correct answer choice.

Correct option is (b) 2sinxcosx

Now using the trigonometric identity of 'sin(a+b)' we can find out the value of sin2x

sin (a + b) = sin a cos b + sin b cos a,

where 'a' and 'b' are angles

let 'a'='x' and 'b'='x'

[tex]sin2x=sin(x+x)\\sin2x=sinx*cosx+sinx*cosx\\sin2x=2sinxcosx[/tex]

Thus 2sinxcosx is the required answer

We have

[tex]a=3\dfrac{1}{2}\ ft[/tex]

Convert to the improper fraction:

[tex]a=\dfrac{3\cdot2+1}{2}=\dfrac{7}{2}\ ft[/tex]

Substitute to the formula of a volume:

[tex]V=\left(\dfrac{7}{2}\right)^3=\dfrac{7^3}{2^3}=\dfrac{343}{8}=42\dfrac{7}{8}\ ft^3[/tex]

Answer:

Step-by-step explanation:

because i did trial and error, i converted all the fractions into decimals until one of the conversions was equal to 2.444444444444...infinite

[tex]2 \frac{4}{9}[/tex] would be the correct answer.

This is not 2.4. This is "2.44444..." because of the line over the 4 after the decimal place (this applies for any decimal such as [tex]2.48\overline{47} = 2.484747474747...[/tex]).

In general, the over-lined part can be written as a fraction of 9 (99, 999, 9999, etc. if the over-lined part has more than one digit, in increasing order of digits), which is why [tex]2 \frac{4}{9}[/tex] is the correct answer.

Answer:

The scale factor of dilation is 1/2

New coordinates are: (-3, 3/2)

Step-by-step explanation:

a) A dilation maps (4,6) to (2,3)

we see that (4/2,6/2) = (2,3)

So, the scale factor of dilation is 1/2

b) if (-6,3) is under same dilation, their new coordinates will be?

We have to multiply (-6,3) by scale factor of 1/2

(-6*1/2,3*1/2) = (-3,3/2)

So, new coordinates are: (-3,3/2)

To solve this problem, we will complete the following steps:
Step 1: Determine the Scale Factor
We are given that the dilation maps the original point (4, 6) to the dilated point (2, 3). To find the scale factor of the dilation, we consider the ratios of the coordinates of the dilated point to the coordinates of the original point. This ratio should be the same for both the x- and y-coordinates since the dilation is uniform.
Scale factor for x-coordinate:
\( \frac{2}{4} = \frac{1}{2} \)
Scale factor for y-coordinate:
\( \frac{3}{6} = \frac{1}{2} \)
Both x and y scale factors are \( \frac{1}{2} \), confirming that the dilation is uniform, and hence the scale factor is \( \frac{1}{2} \).
Step 2: Apply Dilation to the Point (-6, 3)
Now, we want to apply the same scale factor to another point (-6, 3) to find its new coordinates under the same dilation.
\( \text{New x-coordinate} = -6 \times \frac{1}{2} = -3 \)
\( \text{New y-coordinate} = 3 \times \frac{1}{2} = \frac{3}{2} \) or 1.5
Therefore, when the point (-6, 3) is dilated with a scale factor of \( \frac{1}{2} \), the new coordinates are (-3, 1.5).

TW x WU = CW x VW

Fill in the known values:

WU = TU - TW = 21.2 - 14.6 = 6.6

14.6 x 6.6 = 6 x VW

x^2 + x = x^3

5 * 2x^2 x= 10x^3

5x^1+1 = 5x^2

5 * 3x = 15x Put them all together

2x^4 + x^3 - 3x^2 - 10x^3 - 5x^2 + 15x Like terms

2x^4 + x^3 -10x^3 - 3x^2- 5x^2 + 15x Add similar terms

We multiply by 4 on both sides of the equation:

[tex]x = 32 + \frac {4} {2}y\\x = 32 + 2y[/tex]

[tex]-2x+27=4x-9\\[/tex]

Next, combine like terms.

[tex]-2x+27=4x-9\\-2x+36=4x\\36=6x[/tex]

Solve for x.

[tex]36=6x\\6=x[/tex]

The value of "x" in the equation is 6.

To find the value of "x" in the equation -2/3x + 9 = 4/3x - 3, we need to isolate "x" on one side of the equation. Let's solve step-by-step:

Step 1: Get rid of fractions by multiplying all terms by the least common multiple (LCM) of the denominators, which is 3.

3 * (-2/3x) + 3 * 9 = 3 * (4/3x) - 3 * 3

Simplify:

-2x + 27 = 4x - 9

Step 2: Move "4x" and "27" terms to one side and " -2x" and " -9" terms to the other side.

Add 2x to both sides:

-2x + 2x + 27 = 4x - 9 + 2x

Simplify:

27 = 6x - 9

Step 3: Move the constant term " -9" to the other side of the equation by adding 9 to both sides:

27 + 9 = 6x - 9 + 9

Simplify:

36 = 6x

Step 4: Solve for "x" by dividing both sides by 6:

x = 36 / 6

x = 6

The value of "x" in the equation is 6.

Step-by-step explanation:

It is impossible for a triangle to have side lengths of 4, √415, and 16.

The sum of the shortest two sides must be greater than the longest side.  However, 4 + 16 < √415.  

It is impossible to make a triangle with side lengths  4, √415, and 16 because the two side length of the triangle is always greater than the third length of the triangle.

In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.

We have side lengths of a triangle.

As we know from the definition of the triangle the sum of the two side length of the triangle is always greater than the third length of the triangle.

Also, the sum of the interior angle of a triangle is 180 degrees.

As the three lengths are 4, √415, and 16

AB + BC < AC

Let suppose:

AB = 4 units

BC = 16 units

AC = √415 units

4 + 16 < √415

Thus, it is impossible to make a triangle with side lengths  4, √415, and 16.

:) please mark Brainliest

The Smiths' new car purchase price before taxes cannot exceed $23,809.52 considering they have $25,000 and need to pay a 5% sales tax on the purchase.

To calculate the maximum purchase price of the new car before taxes that the Smiths can afford, we need to account for the 5% sales tax they will have to pay on top of the purchase price. Since the Smiths have saved $25,000, this is the total amount they have available to pay for the car including the sales tax.

To find the purchase price before tax, call this price 'P'. The total cost including the sales tax will be P + 0.05P (which is the sales tax). This total cost must not exceed $25,000. Therefore, we can set up the following equation:

1.05P <= $25,000

Divide both sides of the equation by 1.05 to isolate P:

P <= $25,000 / 1.05

P <= $23,809.52

So, the purchase price of the Smiths' new car before taxes cannot exceed $23,809.52.

We can first find the value of the angle at B using the sine formula.

a/sine A=b/Sin B

9/sin 15=12/sin B

Sin B=(12 sin 15)/9

Sin B=0.345

B=20.18°

Therefore angle C =180-(15+20.18)

=144.82°

a/Sin A=c/Sin C

9/Sin 15=c/Sin 144.82

c=(9 sin 144.82)/sin15
