<h3>Solution : </h3>

Let us first solve the value of x in the square .

3x + 1 + 3x + 1 + 3x + 1 + 3x + 1

= 12x + 4 = 2x + x + 8 + 4x + 2

= 12x + 4 = 7x + 8 + 2

Step 1: Simplify both sides of the equation.

12 x + 4 =7x + 8 + 2

12x + 4 = (7x)+(8+2)(Combine Like Terms)

12x+4=7x+10

12x+4=7x+10

Step 2: Subtract 7x from both sides.

12x+4−7x=7x+10−7x

5x+4=10

Step 3: Subtract 4 from both sides.

5x+4−4=10−4

5x=6

Step 4: Divide both sides by 5.

5x / 5 = 6/5

x=6/5

These cones are similar. find the volume of the smaller cone. round to the nearest tenth.
Kamila [148]

Answer:

Volume of the smaller cone = 8.34 cm³

Step-by-step explanation:

"If two figures are similar, their dimensions will be proportional.

Following this rule,

Ratio of the dimensions of two cones = \frac{\text{Radius of the large cone}}{\text{Radius of the small cone}}

                                                               = \frac{r_2}{r_1}

                                                               = \frac{5}{2}

                                                               = 2.5

Similarly, "ratio of the volumes of two similar figures is cube of the dimensional ratio".

Ratio of the volumes = (ratio of the dimensions)³

\frac{V_1}{V_2}=(2.5)^3

\frac{131}{V_2}=15.625

V_2=\frac{131}{15.625}

    = 8.384 cm³  

    ≈ 8.4 cm³

Therefore, volume of the smaller cone is 8.4 cm³.

Aleksandr-060686 [28]

You plug in the numbers listed under x into the equation, and it will give you your y value:

x is 3

y = 4(3)

y = 12


x is 4

y = 4(4)

y = 16


x is 5

y = 4(5)

y = 20
