Answer:

9/20  also 45%

Step-by-step explanation:

well if 20 of them 9 are brown so 9 out of 20 of them are brown/45% of them because out of 20 each thing right or each person is 5%

Answer:

45/100 out of the 20 chickens are brown

Step-by-step explanation:

9/20 = 45/100

9/20 x 5 = 45/100

Answer:

x = 7 5/8

Step-by-step explanation:

Given:

x - 2 5/8 = 6 1/4

first, let's find a common denominator so we can deal with the fractions easier.

The smallest number 8 and 4 is divisible by, is 8.

so we just multiply everything in the equation by 8 now, this helps get rid of the fractions.

x - 2 5/8 = 6 1/4

8 (x -2 5/8) = 8 (6 1/4)

simplifies into

8x -16 + 5 = 48 + 2

simplify some more

8x -11 = 50

solve for x

8x = 11 + 50

8x = 61

x = 61/8

or

x = 7 5/8

Answer:

Decimal: x=8.87

Improper fraction: x=71/8

Mixed number: x=8 7/8

Step-by-step explanation:

[tex]x-2\frac{5}{8}=6\frac{1}{4}[/tex]

First, let's convert mixed numbers to improper fraction

[tex]x-\frac{21}{8}=\frac{25}{4}[/tex]

Now, we can add 21/8 to both sides

[tex]x-\frac{21}{8}+\frac{21}{8}=\frac{25}{4}+\frac{21}{8}[/tex]

[tex]x=\frac{71}{8}[/tex]

We can convert 71/8 to a mixed number

[tex]x=8\frac{7}{8}[/tex]

The steps

Multiply all terms by (x-3)(x+3) and cancel:

x(x+3)+2x(x−3)=18

3x2−3x=18(Simplify both sides of the equation)

3x2−3x−18=18−18(Subtract 18 from both sides)

3x2−3x−18=0

3(x+2)(x−3)=0(Factor left side of equation)

x+2=0 or x−3=0(Set factors equal to 0)

x=−2 or x=3

-6x+12

Step-by-step explanation:

First, -3 distributes to 2x to make it -6x.

Then -3 distributes to -4. A negative times a negative is a positive so it will equal 12.

Answer:

(2x4 + 11x2 - 5)

Step-by-step explanation:

((2•(x5))+(7•(x3)))-(5x-22x3)

((2 • (x5)) +  7x3) -  (5x - 4x3)

(2x5 +  7x3) -  (5x - 4x3)

2x5 + 11x3 - 5x  =   x • (2x4 + 11x2 - 5) 

Factoring  2x4 + 11x2 - 5 

Multiply the coefficient of the first term by the constant  2 • -5 = -10  

Find two factors of  -10  whose sum equals the coefficient of the middle term, which is   
10   +   1   =   -9   
-5   +   2   =   -3
-2   +   5   =   3     
-1   +   10   =   9

Answer:

The answer is below.

Step-by-step explanation:

The solution set for the number line of inequality can be represented as,

{x | x ≤ 4. 5}

The number line is the way of representation of number and digits in a arranged form to understand the data batter.

The meaning of circle in number line,

The number line going from negative 5 to positive 5 and a solid circle appears between positive 4 and positive 5. The middle point of 4 and 5 is 4.5.

The solid or closed circle means that the value has less than or equal to 4.5. Thus, the solution set for the number line of inequality can be represented as,

{x | x ≤ 4. 5}

Answer:

11.08 cm/s

Step-by-step explanation:

Here it is given that the edges of a cube are increasing at a rate of 6.4 cm/s . And we need to find out the rate at which the diagonals are increasing . If we assume each side of the cube to be x , then ;

[tex]\longrightarrow \dfrac{da}{dt}= 6.4 \ cm/s\dots (i) [/tex]

Now we can find diagonal as ,

[tex]\longrightarrow d = \sqrt{ length^2+breadth^2+height^2} [/tex]

Here l = b = h = a ; so ,

[tex]\longrightarrow d =\sqrt{ a^2+a^2+a^2} [/tex]

Simplify,

[tex]\longrightarrow d =\sqrt{3a^2} [/tex]

Take out a from square root,

[tex]\longrightarrow d =\sqrt3 a[/tex]

Now , we can find the rate of change of diagonal as ;

[tex]\longrightarrow r =\dfrac{d\sqrt3 a}{dt} [/tex]

Take out the constant,

[tex]\longrightarrow r = \sqrt3\dfrac{da}{dt} [/tex]

From equation (i),

[tex]\longrightarrow r = 1.732 \times 6.4 \ cm/s [/tex]

Multiply ,

[tex]\longrightarrow \underline{\underline{ rate_{of\ change \ of \ diagonals}= 11.08\ cm/s}}[/tex]

This is the required answer!

If the side length increases at a rate of 6.4 cm/s, then the diagonal increases at a rate of 11.1 cm/s

The diagonal of a cube of side length S is given by:

d = S*√3

In this case, we know that the side length increases at a rate of 6.4 cm/s, then we can write:

S = S₀ + 6.4cm/s*t

Where S₀ is the initial side length, replacing that on the diagonal formula we get:

d = (S₀ + 6.4cm/s*t)*√3

Now if we differentiate it with respect to the time t, we get:

d' = 6.4cm/s*√3 = 11.1 cm/s

So, if the side length increases at a rate of 6.4 cm/s, then the diagonal increases at a rate of 11.1 cm/s.
