Find a ratio equivalent to 15/60

Flauer [41]

Answer:

$\large\boxed{\dfrac{15}{60}=\dfrac{5}{20}=\dfrac{3}{12}=\dfrac{1}{4}}$

$\large\boxed{\dfrac{15}{60}=\dfrac{30}{120}=\dfrac{45}{180}=\dfrac{60}{240}}$

Step-by-step explanation:

Divide the numerator and the denominator by the same number:

$\dfrac{15}{60}\\\\=\dfrac{15:5}{60:5}=\dfrac{3}{12}\\\\=\dfrac{15:3}{60:3}=\dfrac{5}{20}\\\\=\dfrac{15:15}{60:15}=\dfrac{1}{4}\\\vdots$

Multiply the numerator and the denominator by the same number:

$\dfrac{15}{60}\\\\=\dfrac{15\cdot2}{60\cdot2}=\dfrac{30}{120}\\\\=\dfrac{15\cdot3}{60\cdot3}=\dfrac{45}{180}\\\\=\dfrac{15\cdot4}{60\cdot4}=\dfrac{60}{240}\\\vdots$

The volume of a cube is 27 n Superscript 27cubic units. What is the length of one side of the cube? 3 n cubed units 3 n Superscr

NeTakaya

The length of side of cube is $3n^9$ units

Solution:

Given that, volume of cube is $27n^{27}$ cubic units

To find: length of one side of cube

The volume of a cube is given as:

$v = a^3$

Where, "a" is the length of side of cube

Substituting the given value of volume we get,

$27n^{27} = a^3$ ------ eqn 1

We know that,

$27 = 3 \times 3 \times 3 = 3^3$

Substitute the above in eqn 1

$3^3 n^{27} = a^3$

Now again substitute for 27 = 3 x 9

$3^3n^{3.9} = a^3$

Take 3 as common power

$(3n^9)^3 = a^3$

By taking cube roots on both side,

$3n^9 = a\\\\a = 3n^9$

Thus length of side of cube is $3n^9$ units

Find the zeros of the following please solve step by step 1. x³+9x²+26x+24=0

Vlad1618 [11]

Answer: -4, -3, -2

Step-by-step explanation:

By inspection, we know $x=-2$ is a root.

We can thus rewrite the equation as

$(x+2)\left(\frac{x^3 + 9x^2 + 26x+24}{x+2} \right)=0\\\\(x+2)(x^2 + 7x+12)=0\\\\(x+2)(x+3)(x+4)=0\\\\x=-4, -3, -2$
