Answer:

i believe the answer is 2.5

Step-by-step explanation:

The value of x in the given right cone is 10 units.

A cone is a geometrical shape in three dimension formed by a set of lines joined from a point to every points on the base surface which is a  circle.

The common point where the lines join is called apex.

The distance from apex to the circular base is called the height of the cone.

The radius of the circular base is also the radius of the cone.

Volume of a Cone is calculated as V = [tex]\frac{1}{3}[/tex] πr²h, where h is the height of the cone and r is the radius of the cone.

We have, Volume of the cone = 30π units³.

From the figure given, diameter of the circular base = 6 units

So, the radius of the cone = 6/2 = 3 units

We have to find the height of the cone.

Substituting these values in the equation for the volume,

30π = [tex]\frac{1}{3}[/tex] π × 3² × h

30 = = [tex]\frac{1}{3}[/tex] × 3² × h

30 = 3h

h = 10

Hence, the height of the cone with radius 3 units and volume 30π units is 10 units.

Answer:

  (a)  5 : 8 < 7 : 10

  (b) 9/6 = 36/24

Step-by-step explanation:

Perhaps simplest to explain is the use of a common denominator: 40.

  [tex]5 : 8 = (5\cdot5):(8\cdot5)=25:40\\\\7:10=(7\cdot4):(10\codt4)=28:40\\\\25:40 < 28:40\quad\leftrightarrow\quad\boxed{5:8 < 7:10}[/tex]

__

Other ways you can do this comparison are ...

  Multiply by 8·10 = 80, the product of the denominators:

     5·10 = 50 < 7·8 = 56

  Convert the fractions to decimal:

     5/8 = 0.625 < 7/10 = 0.700

Remove a factor of 4 from the second fraction:

  [tex]\dfrac{9}{6}\text{ and }\dfrac{36}{24}\quad\leftrightarrow\quad\boxed{\dfrac{9}{6}=\dfrac{9\cdot4}{6\cdot4}}[/tex]

Answer:

3⁻ⁿ⁺²

Step-by-step explanation:

we need to make both bases the same

9 can be written as 3²

[tex] \frac{3 {}^{n} }{3 {}^{2(n - 1)} } [/tex]

multiply 2(n-1) = 2n - 2

[tex] \frac{3 {}^{n} }{3 {}^{2n - 2} } [/tex]

I'll rewrite as 3ⁿ ÷ 3²ⁿ⁻²

subtract the exponents when dividing numbers with the same base

n - (2n-2) or n - 1(2n-2) imagine the 1 is there

remember that the whole of (2n-2) is being multiplied by -1, so expanding

n - 2n + 2 = -n + 2

final answer: 3⁻ⁿ⁺²

Answer:  Choice C

(3 x 8) x 6 = 3 x (8 x 6)

=================================================

Explanation:

The associative property in general is

(a x b) x c = a x (b x c)

where the x stands for the multiplication symbol.

The a,b,c is in the same order for both sides, but grouped in slightly different ways with the parenthesis.

Plug in a = 3, b = 8, c = 6 to arrive at (3 x 8) x 6 = 3 x (8 x 6)

Answer:

for (a)

8m

(b)

1m

Step-by-step explanation:

(a) the area of a square =L*B

√64

=8m

(b)the perimeter of a square=4L

4*1=4m

(a) A square has an area of 64 m² . What is the length of each side .

As we know that area of square is equal to side² . So we have to equate the formula with given area . So :

Therefore , each side of square is of 8 m .

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

(b) A square has a perimeter of 4 cm . What is the length of each side .

As we know that perimeter of square 4 cm , therefore we have to equate it with perimeter formula and then solve . So :

Therefore , each side of square is of 1 cm .

Given :

⠀

To Find :

⠀

Solution :

We know that,

[tex]\qquad { \pmb{ \bf{Length \times Width = Area_{(rectangle)}}}}\:[/tex]

So,

Let's assume the length of the rectangle as x and the width will be (x – 4).

⠀

Now, Substituting the given values in the formula :

[tex]\qquad \sf \: { \dashrightarrow x \times (x - 4) = 45 }[/tex]

[tex]\qquad \sf \: { \dashrightarrow {x}^{2} - 4x = 45 }[/tex]

[tex]\qquad \sf \: { \dashrightarrow {x}^{2} - 4x - 45 = 0 }[/tex]

[tex]\qquad \sf \: { \dashrightarrow {x}^{2} - 9x+ 5 x - 45 = 0 }[/tex]

[tex]\qquad \sf \: { \dashrightarrow x(x - 9) + 5(x - 9) = 0 }[/tex]

[tex]\qquad \sf \: { \dashrightarrow (x - 9) (x + 5) = 0 }[/tex]

[tex]\qquad \sf \: { \dashrightarrow x = 9, \: \: x = - 5}[/tex]

⠀

Since, The length can't be negative, so the length will be 9 which is positive.

⠀

[tex]\qquad { \pmb{ \bf{ Length _{(rectangle)} = 9\:m}}}\:[/tex]

[tex]\qquad { \pmb{ \bf{ Width _{(rectangle)} = 9 - 4=5\: m}}}\:[/tex]

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

The length is 9m and the width is 5m.

This is defined as is a quadrilateral with four right angles and the area is calculated as Length × width.

Let's assume length is x and width is (x-4).

We have x × (x-4) = 45m²

x² - 4x = 45

x² - 4x - 45 = 0

x² - 9x + 5x -45 = 0

x(x-9) +5 (x-9)

(x+5)(x-9) = 0

x = -5 or x = 9

x is therefore 9m and the width is (9-4) = 5m

The break even point is the point where the cost and the revenue are equal

The break even point is at x = 50

The functions are given as:

C(x) = 30x + 500 --- cost function

R(x) = 40x ---- revenue function

At the break even, we have:

R(x) = C(x)

So, the equation becomes

40x = 30x + 500

Subtract 30x from both sides

10x = 500

Divide both sides by 10

x = 50

Hence, the break even point is at x = 50
