Answer:

Option (2)

Step-by-step explanation:

Given expression is [tex]\frac{2}{(3x-1)}[/tex] ÷ [tex]\frac{6}{6x-1}[/tex]

We further simplify this expression,

[tex]\frac{2}{(3x-1)}[/tex] ÷ [tex]\frac{6}{6x-1}[/tex]

= [tex]\frac{2}{(3x-1)}\times \frac{6x-1}{6}[/tex]

= [tex]\frac{6x-1}{3(3x-1)}[/tex]

= [tex]\frac{6x-1}{(9x-3)}[/tex]

Therefore, [tex]\frac{6x-1}{(9x-3)}[/tex] will be the quotient of the given expression.

[tex]x\neq \frac{1}{3}[/tex] and [tex]x\neq \frac{1}{6}[/tex] for which the given expression is not defined.

Option (2) will be the answer.

Answer:

3540

Step-by-step explanation:

There are 3520 yards in two miles and 1760 in one mile you multiply 1760 by 2 then add 20

Answer:

Step-by-step explanation:

Multiplicity of a number is the number of times the factor of a given function appears in the factor form of such given equation. For us to know the multiplicity of the root of the function, first we must know its root.

Factorizing the given quadratic function  x²−8x+16=0

[tex]x^{2} -4x-4x+16 = 0\\x(x-4)-4(x-4)=0\\(x-4)(x-4) = 0\\x-4 = 0 and x-4 = 0\\x = 4\ twice[/tex]

Since the root of the function which is 4 appears twice then the multiplicity of the root is 2

The answer is B part

As the requirement for the student is either a senior or one who studies maths or both.

So, just add the values within the two venn circles divide it by total no of values.

=> 240+40+110/240+40+110+840

=> 360/1200

Answer:

B

Step-by-step explanation:

840 people aren't senior or don't takes math.

210 + 40 = 250 are seniors

110 + 40 = 150 people take math

In this class has 840 + 210 + 40 + 110 = 1200 people => All

210 + 40 + 110 = 360 people are seniors or take math. => P( S U M)

Probabilty that a randomly selected student is a senior or takes math =>[tex]\frac{P(S U M)}{All}[/tex]

[tex]\frac{P(S U M)}{All} = \frac{360}{1200}[/tex]

For online calculators you can type sqrt() or just sqrt and it will do it for you

Answer:

Step-by-step explanation:

To simplify radicals that are not perfect squares, we need a new method.

Example: [tex]\sqrt{27}[/tex]

27 is not a perfect square square the square root cannot be used.

[tex]\sqrt{27} = 5.19615242271[/tex]

To solve this, we need to break down the radical into simpler parts.

[tex]\sqrt{27} = \sqrt{3} * \sqrt{9}[/tex]

[tex]\sqrt{9} = 3[/tex]

[tex]\sqrt{3}[/tex] cannot be simplified

[tex]\sqrt{27}[/tex] = 3[tex]\sqrt{3}[/tex]

Answer: 7 1/30

Step-by-step explanation:

Tina loves to read. Before breakfast, she read 2 1/2 pages, at lunch she read 3 1/5 pages, and after dinner she read 1 1/3 pages. To find the total, we add all the pages together. This will be:

2 1/2 + 3 1/5 + 1 1/3

The LCM of 2, 5 and 3 is 30.

= 2 15/30 + 3 6/30 + 1 10/30

= 6 31/30

= 7 1/30.

Mean is 50

Step-by-step explanation:

20 + 30 + 40 + 50 + 60 + 70 + 80 = 350

350 / 7 = 50

Answer:

50

Step-by-step explanation:

Mean means average number which sum of all numbers divided how many numbers we are investigating

We are investigating 7 numbers

The total sum of these numbers are:

20 + 30 + 40 +50+ 60+70+80= 350

Mean = 350/7= 50

Answer:

A cone with a diameter of 18ft and a slant height of 30ft

Using Pythagorean theorem, the height is calculated by:

H = sqrt(18^2 - (30/2)^2) = 9.95

The surface area:

A = lateral surface area + base

A = pi x radius x slant height + pi x radius^2

A = pi x (30/2) x 18 + pi x (30/2)^2 = ~1555.1 (ft2)

The volume:

V = base x height x (1/3)

V = pi x radius^2 x height

V = pi x (30/2)^2 x 9.95 = 7033.2 (ft3)

Hope this helps!

option b is the correct answer

Answer:

x=3

Step-by-step explanation:

Answer:

The answer would be 3.

Step-by-step explanation:

Answer: a ≤ 4 or (-∞, 4]

Step-by-step explanation:

Here we have the inequality:

4a ≤ 16

this means that the left sides is less or equal than the right side.

First, find the equal part:

4*a = 16

a = 16/4 = 4

So the maximum possible value of a is 4.

Now, all the values of a smaller than 4 also make the inequality true (even the negative values) so the possible values of a are:

a ≤ 4 or (-∞, 4]

Answer:

Any number that is less or equal to 4 makes this inequality true.

Step-by-step explanation:

In order to calculate the numbers that make this inequality valid, we need to solve it for "a". This can be done in the same manner as we would solve an equation, although we must pay attention to the inequality. This is done below:

[tex]4*a \leq 16\\a \leq 16/4\\a \leq 4[/tex]

Any number that is less or equal to 4 makes this inequality true.

Answer:

36,811 cubic feet.

Step-by-step explanation:

Volume = 1/2 volume of a sphere

= 1/2 * 4/3 π r^3

= 2/3 * π r^3

R = 26 so

Volume of the tank = 2/3 *  π 26^3

= 36811.09 feet^3.

The volume of the tank in cubic feet approximate  is 36,811 cubic feet.

If the given sphere is of radius r units, then its volume is given as:

[tex]V= \dfrac{4}{3} \pi r^3 \: \rm unit^3[/tex]

We are given water storage tank is in the shape of a hemisphere​ (half a​ sphere). If the radius is 26 ​ft.

Therefore,

Volume = 1/2 volume of a sphere

= 1/2 * 4/3 π r^3

= 2/3 * π r^3

R = 26

Therefore, Volume of the tank = 2/3 π 26^3

= 36811.09 feet^3.

A) Measure of an interior angle of polygon = 150°

B) No of sides = 12

C) Sum of all interior angles = 1800°

16x - 5 = 15x

16x - 16x -5 = 15x - 16x

-5 = -x

-5 / -1 = -x / -1

x = 5

mAB = 5(5)

mAB = 25°

Step-by-step explanation:

1. set arc FA and arc CD equal to each other.

2. subtract 16x from both sides.

3. divide both sides by -1 to get x.

4. replace x by its value to solve for mAB.

Answer:

Perimeter = 4.5√3 + 4.5

Area = 3.375√3

Step-by-step explanation:

Well you can first see that triangle ABC is a 30°60°90° triangle.

Since angle A is 60 and it is bisected, you will have a small 30°60°90° triangle and a 120°30°30° triangle.

You can say that DA is congruent to BD by Base Angle Theorem.

DA = 3

By using the ratios of the sides of the 30°60°90° you get that CD is 1.5 and CA is 1.5√3

CD = 1.5

CA = 1.5√3

BC = 4.5

Area = (4.5 * 1.5√3) / 3 = 6.75√3 / 2

Area = 3.375√3

By using the 30°60°90° ratio again, you get that BA = 3√3

Perimeter = 1.5√3 + 3√3 + 4.5

Perimeter = 4.5√3 + 4.5
