I need help on how to do the percentage ​

Considering the volume of a cone, the height if the cone is 5 units.

A cone is a three-dimensional figure with a circular base, where a curved surface connects the base and the vertex.

The cone is a figure that is generated by rotating a right triangle around one of its legs.

Volume is the place that a body occupies in space.  

In the case of the cone, the volume is calculated knowing the height (h) and the radius (r). Its volume is defined as one third of the area of ​​the base B times the height h. This is:

V=[tex]\frac{1}{3}[/tex] ×B ×h

Being B=π× r²

V=[tex]\frac{1}{3}[/tex] ×π× r² ×h

In this case, you know:

Replacing:

135π units³= [tex]\frac{1}{3}[/tex]×π× (9 units)² ×h

Solving:

135π units³= [tex]\frac{1}{3}[/tex]×π× 81 units² ×h

135π units³÷ ([tex]\frac{1}{3}[/tex]×π× 81 units²)= h

5 units= h

Finally, the height if the cone is 5 units.

Step-by-step explanation:

the answer is not 6,2 ive tried it ?

The solution of the given system of equation is (6, 2)

Two or more equations to be solved together, i.e., the solution must satisfy all the equations in the system.

Given are the equations, 3x + 2y = 22

-x + 4y = 2

Solving by elimination,

Multiplying the second equation by 3, we get

3x+2y = 22

-3x + 12y = 6

Adding the equation, we get

2y+12y = 22+6

24y = 28

y = 2

Putting y=2 we get

3x+2*2=22

3x+4 = 22

3x = 18

x = 6

Hence, The solution of the given system of equation is (6, 2)

Step-by-step explanation:

The rate of change is D. 1foot 5inches (17inches) 8inches.

The foot is a measure of a unit of length (or distance) in US units, which equals 12 inches.

The rate of change is the difference between x and y variables.  It can be mathematically expressed as ​Change in input/​Change in output​​.  The formula for the rate of change is as follows:

= ​Δx/Δy

where Δ = change

14inches + 8inches = 22inches

13inches + 7.5inches = 20.5inches

18inches + 8inches = 26inches

But 17inches + 8inches = 25inches

Find the rate of change from 2feet 1 inch (25inches) to 8inches.

Thus, the rate of change is D. 1foot 5inches (17inches) 8inches.

2.5      16.25         22

1.5       12.25        20

0.5       10.25       18

We see the pattern that it is increasing with only a unit. The last given data is mid of the last two values that is 3 and 4.

So the next value would be the mid of the next last two values that is 2 and 3 and will be 2.5

Now it is moving in the reverse direction in the same pattern  with a difference of a unit.

5) ΔGHJ ≅ ΔXYZ

ΔGHJ is an isosceles triangle. So, GH = JH

GH =JH = 27 ft

a) GJ =XZ

  GJ =  18 ft

b) XY = GH

 XY = 27 ft

c) ZY = JH

   ZY = 27 ft

d) ∠H = ∠Y

∠H = 38

In ΔGHJ,

∠G = ∠J      {Isosceles triangle property}

Let ∠G = ∠J = x

∠G + ∠H + ∠J = 180  {angle sum property of triangle}

x + 38 + x = 180

    38 +2x = 180

           2x = 180 - 38

           2x = 142

            x = 142/2

x = 71

∠G = ∠J =  71

e) ∠Z = ∠J

  ∠Z = 71

f) ∠J = 71

9) ΔQRS ≅ ΔMNP

QR = 11   ; QS =15

MP = 2x +1

MP = QS

2x + 1 = 15

   2x = 15 - 1

   2x = 14

    x = 14/2

   x = 7

m∠S = 84

m∠R = 32

m∠Q = 17y - 4

In ΔQRS,

m∠Q + m∠R + m∠S = 180    {Angle sum property of triangle}

17y - 4 + 32 + 84 = 180

             17y + 112 = 180

                      17y =  180 - 112

                      17y = 68

                         y = 68/17

y = 4

Reduced fraction

Step-by-step explanation:

One can always multiply numerator and denominator by the same number in order to find equivalent fractions. By in the case in which only multiplication (and not cancelling common factors) will help find an equivalent fraction, si when we are dealing with an already reduced fraction.

For example:

1/3 (one third), we can multiply numerator and denominator by a factor of 2 and get the equivalent fraction 2/6 as shown below:

[tex]\frac{1}{3} =\frac{1*2}{3*2} =\frac{2}{6}[/tex]

but one cannot reduced the fraction 1/3 any further because it is already a reduced fraction.

Answer:

  A (as marked)

Step-by-step explanation:

It often works well to eliminate the answer choices that can't be right.

The constant term of the sum must be ...

  -7 + 4 = -3 . . . . . eliminates choices B and D

The highest-degree term of the sum must be ...

  ( ) +(3x^2y^2) = 3x^2y^2 . . . . eliminates choice C

The remaining viable choice is A. Checking the sum term by term, you find A is the correct choice.

1.56x + 10.15

Step-by-step explanation:

(5.23x + 3.76) – (3.67x – 6.39)

(a + b) – (c – d) = a + b – c + d

Remove the parentheses and change the signs as needed:

5.23x + 3.76 – 3.67x + 6.39.

Group the like terms and simplify:

5.23x – 3.67x + 3.76 + 6.39

1.56x +10.15.

The simplified form of (5.23x + 3.76) – (3.67x – 6.39) is 1.56x + 10.15.

Subtract 25 from both sides;

13x < -26

Divide both sides by 13;

x < -2

-9x + 5 < 17

Subtract 5 from both sides;

-9x < 12

Divide both sides by -9
