Answer:

x = 3

Step-by-step explanation:

Given 2 intersecting chords, then

The product of the parts of one chord is equal to the product of the parts of the other chord, that is

5x × x = 5 × 9

5x² = 45 ( divide both sides by 5 )

x² = 9 ( take the square root of both sides )

x = $\sqrt{9}$ = 3

If the sphere shown above has a radius of 11 units then what is the approximate volume of the sphere

adell [148]

Answer:

Volume of the sphere $=5563.58units^3$

Step-by-step explanation:

Volume of the sphere= $\frac{4}{3} *\pi *r^3$

The sphere has given radius(r)= 11 units

Putting the value of the radius in the formula;

Volume of the sphere:

= $\frac{4}{3} *3.14*11*11*11$

$=1.33*3.14*11*11*11$

$=4.18*11*11*11$

$=4.18*1331$

Volume $=5563.58units^3$

The volume of the sphere with radius of 11 units is $5563.58units^3$

8x^3-8x=1<br> Solve for x

Anit [1.1K]

Step-by-step explanation:

Step-by-step explanation:

\begin{gathered} \frac{8x - 3}{3x} = 2 \\ 8x - 3 = 6x \\ 8x - 6x = 3 \\ 2x = 3 \\ x = \frac{3}{2} \end{gathered}

8x−3

8x−3=6x

8x−6x=3

What is the value of x, the side length of the smallest square (please show work) Thanks!

Ratling [72]

Answer:

8 cm

Step-by-step explanation:

Ok lets on the biggest square we have 17 cm

17cm is the hypotenuse for the right triangle

The second largest's area is 225 cm^2

Sq root of 225 cm^2, is 15

To find x, lets plug the info we have to the pythagorean theorom

$a^2 + b^2 = c^2\\a^2 + 15^2 = 17^2\\a^2 + 225 = 289\\\\289 - 225 = a^2\\64=a^2\\a = 8 cm$

The side length of the smallest Square is 8 cm

If my answer is incorrect, pls correct me!
