saw5 [17]4 years ago
5 0

if a whole number, put the number above a one like so : if the number was 8, write it as 8/1

multiply the number by the reciprocal of the fraction

example: 8 divided by 1/3

8/1 times 3/1 =24/1

=24

What is 5/6 divided by 1/7?
skelet666 [1.2K]

Answer:

5\frac{5}{6}

Step-by-step explanation:

To divide fractions, we multiply the first fraction by the <u>reciprocal </u>of the second fraction. (Seven over one)

\frac{5*7}{6*1} =\frac{35}{6}

Now, we convert the fraction into a mixed fraction.

\frac{35}{6}=5\frac{5}{6}

<em>The quotient of 5/6 and 1/7 is 5 5/6</em>

10(4-3i)= whats the answer
LenaWriter [7]

Answer: Hi!

To solve this equation, we first distribute to the terms inside of the parentheses.

10*4 = 40

10*-3i = -30i

Our equation now looks like this:

40 - 30i

There is nothing left to simplify, so you're done!

Hope this helps!

In the equation f(x) = (3x + 5) (x2 - 6x + 9)2 = 0, 3 has a multiplicity of ______.
Svetradugi [14.3K]
Multiplicity is how many times the root (or zero) is repeated

example, in f(x)=a(x-b)^n(x-d)^m... the root b has a multiplicity of n and the root d has a multiplicity of m

first we need to get the roots into f(x)=a(x-b)^n(x-d)^m
for (3x+5), we need to force factor out the 3 to get
3(x+\frac{5/3})

factor the other one
(x^2-6x+9)=(x-3)(x-3)=(x-3)^2
but it is (x^2-6x+9)^2 which is equivilent to ((x-3)^2)^2 which simplifies to (x-3)^4

so we get
f(x)=3(x+\frac{5}{3})(x-3)^4
so the roots are -5/3 multiplicity 1 and 3 multiplicity 4


3 has a multilicity of 4

Los dueños de un restaurante cultivan sus propios
zzz [600]

Answer:

Quedan 2.083 m^3 de agua en el reservorio.

Equivalen a 2083 litros.

Step-by-step explanation:

Los dueños del restaurante tienen un reservorio de agua cuyo volumen es de 6.25 m^3.

Si han utilizado 2/3 del reservorio, esto implica que aún quedan en el reservorio una tercera parte del volumen original (1/3).

Entonces, la cantidad de metros cúbicos (m^3) de agua que quedan en el reservorio se puede calcular como:

V=(1/3)\cdot V_0=(1/3)\cdot6.25\,m^3=2.083\,m^3

Este valor equivale a un volumen en litros de:

V=2.083\,m^3\cdot \dfrac{1,000\,l}{1m^3}=2,083\,l
