Therefore, the correct option is D.

In a 30-60-90 triangle, the longer leg is sqrt(3) times the hypotenuse. Therefore, the correct ratios provided are A. sqrt(3) : 2 and D. 3sqrt(3) : 6, with the latter simplifying to the correct ratio when reduced.

The ratio of the length of the longer leg to the hypotenuse in a 30-60-90 triangle is determined by the properties of this special right triangle. In such a triangle, the sides are in a fixed ratio: the shorter leg is 1 times the length of the hypotenuse, the longer leg is sqrt(3) times the length of the hypotenuse, and the hypotenuse itself is 2 times the length of the shorter leg.

Using this knowledge, we can evaluate the options given:

Options B, C, E, and F do not represent the correct ratio of the longer leg to the hypotenuse of a 30-60-90 triangle. Therefore, options A and D are correct.

Answer:

21.99 units

164.93 units²

Step-by-step explanation:

given radius r = 15 units

angle of sector = 84°

Length of sector = [tex]\frac{84}{360}[/tex] x 2 x π x r

= [tex]\frac{84}{360}[/tex] x 2 x 3.14 x 15

= 21.99 units

Area of sector = [tex]\frac{84}{360}[/tex] x π x r²

= [tex]\frac{84}{360}[/tex] x 3.14 x 15²

= 164.93 units²

Answer:

The height is 6.

Step-by-step explanation:

To find the answer, identify the dimensions you have and what you to find. We have the area (144) and base (24) and we need to find the height. To find the height, you must divide area by the base (it's really simple).

Ex.

[tex]144 / 24 = ?\\144 / 24 = 6[/tex]

The quotient you found is the height. Therefore, the answer is 6.

Final answer:

To find the height of a parallelogram with an area of 144 cm² and a base of 24 cm, divide the area by the base to obtain the height of 6 cm.

Explanation:

Mathematics:

To find the height of a parallelogram, you can use the formula Area = base * height. In this case, the area is given as 144 cm² and the base is 24 cm. Substituting these values into the formula, we get 144 = 24 * height. To find the height, divide both sides of the equation by 24: height = 144/24 = 6 cm. Therefore, the height of the parallelogram is 6 centimeters.

Answer:

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

Step-by-step explanation:

When we have a point (a,b) on the unit circle, we can say that

[tex]a^2+b^2=1[/tex]

This is a property of the unit circle.

From the point given  [tex](x,\frac{\sqrt{3} }{2})[/tex] , now we can write the equation shown below and solve for x:

[tex]x^2+(\frac{\sqrt{3} }{2})^2=1\\x^2+\frac{3}{4}=1\\x^2=1-\frac{3}{4}\\x^2=\frac{1}{4}\\x=\frac{\sqrt{1}}{\sqrt{4} } \\x=\frac{1}{2}[/tex]

So, x = 1/2

Answer: x = 1/2

Step-by-step explanation:

We have that the point (x, (√3)/2)) is on the unit circle.

we can define a circle of radius R centered in the (0,0) as:

x^2 + y^2 = R^2

This means that:

x^2 + (√(3)/2)^2 = 1

x^2 + 3/4 = 1

x^2 = 1 - 3/4 = 1/4

x = √(1/4) = 1/2

So we have that x is equal to 1/2

Answer:

Step-by-step explanation:

Assuming the problem is: 3/4  x +5/8=4x

Or .75 x+5/8=4x

Subtract .75 on both sides: 5/8=3.25x

Then divide both sides by 3.25:       (5/8)/3.25=x

So x=5/26

The statement most accurately describes the relationship between

segments of the triangles formed by the beam is AC < DF

Step-by-step explanation:

* Lets study the figure to answer the problem

- There are two triangles ABC and DEF

- AB = BC

- DE = EF

- AB = DE

∴ AB = BC = DE = EF

- m∠ABC = 45°

- m∠DEF = 60°

∵ The measure of angle ABC is smaller than the measure of

   angle DEF

∴ The opposite side to the angle ABC is shorter than the opposite

   side of angle DEF

∵ AC is the opposite side to angle ABC

∵ DF is the opposite side to angle DEF

∴ AC is shorter than DF

∴ DF > AC

∴ AC < DF

* The statement most accurately describes the relationship between

  segments of the triangles formed by the beam is AC < DF

Answer:

444 (gets to 62,666)

Step-by-step explanation:

The closest you can think of first is 63,333. However, as long as there doesn't have to be the four numbers in a row, the "6" in the number can be one of the four same numbers.

This means that you need to get 3 other sixes in the number. There are many ways to do this, but the one requiring the least amount of driving is changing the last three digits (222). If you add 444 to the number, the amount of miles driven is 62,666, there being 4 sixes in the number. This is the least amount of driving needed before the odometer shows four of the five digits the same as each other.

444 is the least number that shows four out of the five digits same.

An odometer is an instrument for measuring the distance travelled by a wheeled vehicle.

Given that,

Total distance covered by Mr. Jackson = 62,222 miles,

The four digits of number 62,222 are same and are 2,

Again, odometer will show four out of 5 digit same, when there will be at least four times 6,

So add 444 in the 62,222

The number = 62,222 + 444 = 62,666

So the least number that can be added to make 4 digit same is 444.

The length of the given rectangle is 3 yd and the width is 3.66 yd.

A rectangle is a type of parallelogram having equal diagonals.

All the interior angles of a rectangle are equal to the right angle.

The diagonals of a rectangle do not bisect each other.

Given that,

The area of rectangle is 42 square yd.

Suppose the width of the rectangle is x yd.

Then its length is given by 3x - 11 yd.

As per the problem, the following equation can be formed,

x(3x - 11) = 42

Solve the above equation for x as,

x(3x - 11) = 42

=> 3x² - 11x = 42

=> 3x² - 11x - 42 = 0

=> x = -1, 4.66

Since, the width cannot be negative. The value of x is taken as 4.66.

Thus, the length is is given by 3 × 4.66 - 11 = 3.

Hence, the length and width of the rectangle are 3yd and 4.66yd respectively.

The coordinates of the roots of the given quadratic equation x^2 + 4x + 3 = 0 are -1 and -3.

The given equation is a quadratic equation in the form of ax² + bx + c = 0, where a = 1, b = 4, and c = 3. To find the coordinates of the roots, we can use the quadratic formula:

x = (-b ± √(b² - 4ac)) / (2a)

Substituting the given values, we get:

x = (-4 ± √(4² - 4(1)(3))) / (2(1))

Simplifying further, we have:

x = (-4 ± √(16 - 12)) / 2

x = (-4 ± √4) / 2

x = (-4 ± 2) / 2

Therefore, the two roots of the equation are:

x₁ = (-4 + 2) / 2 = -1

x₂ = (-4 - 2) / 2 = -3

The answer is:

The solutions to the system of equations are:

[tex]x=0\\y=1\\z=0[/tex]

To solve the system of equations by the easiest way, we need to use the reduction method. The reduction method consist of reducing the variables applying different math operations in order to be able to isolate the variables.

So, we are given the system:

[tex]4x+3y+6z=3\\5x+5y+6z=5\\6x+3y+6z=3[/tex]

Let's work with the first and the third equation:

[tex]4x+3y+6z=3\\6x+3y+6z=3[/tex]

Then, multiplying the first equation by -1, we have:

[tex]-4x-3y-6z=-3\\6x+3y+6z=3[/tex]

[tex]-4x+6x-3y+3y-6z+6z=-3+3[/tex]

[tex]2x=0[/tex]

[tex]x=0[/tex]

Now, working with the first and the second equation, we have:

[tex]4x+3y+6z=3\\5x+5y+6z=5[/tex]

Then, multiplying the first equation by -1, we have:

[tex]-4x-3y-6z=-3\\5x+5y+6z=5[/tex]

[tex]5x-4x+5y-3y-6z+6z=-3+5[/tex]

[tex]x+2y=2[/tex]

Then, substituting "x" into the equation, we have:

[tex]0+2y=2[/tex]

[tex]y=\frac{2}{2}=1[/tex]

Finally, working with the first equation and substituting "x" and "y", we have:

[tex]4x+3y+6z=3[/tex]

[tex]4*0+3*1+6z=3[/tex]

[tex]0+3+6z=3[/tex]

[tex]6z=3-3=0[/tex]

[tex]6z=0[/tex]

[tex]z=\frac{0}{6}=0[/tex]

Hence, we have that the solutions to the system of equations are:

[tex]x=0\\y=1\\z=0[/tex]

Have a nice day!

Answer:

[tex]x=0\\y=1\\z=0[/tex]

Step-by-step explanation:

Multiply the first equation by -1:

[tex](-1)(4x+3y+6z)=3(-1)\\\\-4x-3y-6z=-3[/tex]

Add the new equation and the third equation an solve for "x":

[tex]\left \{ {{-4x-3y-6z=-3\ \atop {6x+3y+6z=3} \right.\\...........................\\2x=0\\x=0[/tex]

Substitute the value of "x" into the first equation and solve for "y":

[tex]4(0)+3y+6z=3\\\\3y=3-6z\\\\y=\frac{3-6z}{3}\\\\y=1-2z[/tex]

Substitute the value of "x" and [tex]y=1-2z[/tex] into the second equation and solve for "z":

[tex]5(0)+5(1-2z)+6z=5\\\\5-10z+6z=5\\\\-4z=0\\\\z=0[/tex]

Knowing the values of "x" and "z", you can substitute them into any original equation and solve for "y". Then:

Answer:

A = 47° and B = 43°

Step-by-step explanation:

Express angle A in terms of angle B, that is

A = B + 4

Complementary angles sum to 90°, hence

A + B = 90, that is

B + 4 + B = 90

2B + 4 = 90 ( subtract 4 from both sides )

2B = 86 ( divide both sides by 2 )

B = 43

Hence

∠B = 43° and ∠A = B + 4 = 43 + 4 = 47°

Answer:

A= 47°

B= 43°

Explanation:

A complementary angle is a 90° angle.

If A+B= 90 and B+4= A, we can rewrite it as...

B+4+B= 90

→ 2B+4= 90

→ 2B= 86

→ B= 43

Then we go back to the equation A+B= 90 and plug in B as 43...

A+43= 90

Step-by-step explanation:

hihi, so given a statistic, a sample standard deviation, and the sample size, we can create a 99% confidence interval for this distribution. Given the equations for confidence interval and Margin of Error, all we have to calculate initially is t* (invT(.995, 85-1)) and Standard error (34/sqrt(85)). Once we have these numbers, it's as easy as plugging in and doing some simple calculations to reaching our upper and lower fences of our interval. (136.28, 155.72). Any value below the lower fence or any value above the upper fence is not in our interval

The 99% confidence interval for the given random sample is between 136.5 and 155.5. The critical value for a 99% of confidence interval is 2.58.

The formula for the confidence interval is

C.I = μ ± Margin error

Where Margin error = critical value × Standard error and μ - mean

Standard error = δ/[tex]\sqrt{n}[/tex]

δ - standard deviation and n is the sample space.

The critical value (z) is obtained from the percentage confidence interval table.

Given that,

Sample space n = 85

Mean μ = 146 and δ = 34

Calculating the standard error:

S.E = δ/[tex]\sqrt{n}[/tex]

      = 34/√85

      = 3.68

The critical value for the 99% of the confidence interval is 2.58

Calculating the Margin error:

Margin error = 2.58 × 3.68

                     = 9.49

                     = 9.5

Then the 99% of the confidence interval is calculated as follows:

C.I = μ - Margin error (lower interval)

    = 146 - 9.5

    = 136.5

C.I = μ + Margin error (upper interval)

    = 146 + 9.5

    = 155.5

Thus, the 99% confidence interval is 136.5 - 155.5.
