We would have to see the spinner, is there more than one white slice? If not then the probability would be 1/9 or 1:9 because there are one white slice and nine slices in all.

<h3>b)</h3>

\frac{3 {a}^{2}  - 9a}{ {a}^{2}  - 9}  =  \frac{3a(a - 3)}{(a + 3)(a - 3)}  =  \frac{3a}{a + 3}

<h3>c)</h3>

\frac{ {y}^{2} - 3yz -4  {z}^{2}  }{3 {y}^{2} - 12yz }  =  \frac{(y + z)(y - 4z)}{3y(y - 4z)}  =  \frac{y + z}{3y}

<h3>d)</h3>

\frac{ {d}^{2} + 4d  + 4}{ {d}^{2}  + 2d}  =  \frac{(d + 2)(d + 2)}{d(d + 2)}  =  \frac{d + 2}{d}

<h3>e)</h3>

\frac{5f - 15}{3 {f}^{2}  - 13f + 12}  =  \frac{5(f - 3)}{(3f - 4)(f - 3)}  =  \frac{5}{3f - 4}

I hope I helped you^_^

Calculate x<br> I ll mark you as the brainliest
Lunna [17]

Answer

x = 18 cm

Step-by-step explanation:

Here, we want to calculate the value of x

let half of x = b

so b is the base of each right-triangle

As we can see, the triangle is isosceles

we can calculate the length of the base of one of the smaller right angled triangle and multiply by 2 to get the full x length

According to Pythagoras’ , the square of the hypotenuse equals the sum of the squares of the two other sides

15^2 = 12^2 + b^2

225 = 144 + b^2

b^2 = 225-144

b^2 = 81

b = √81

b = 9

but x = 2b

x = 2(9)

x = 18 cm

Solve for x.<br> -4 &lt; 11 - 3.2
goldenfox [79]

Answer:

-4<11-(32/10)  

Inequality is always true

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "3.2" was replaced by "(32/10)".

Rearrange:

Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :

                    -4-(11-(32/10))<0  

Step by step solution :

Step  1  :

           16

Simplify   ——

           5  

Equation at the end of step  1  :

              16

 -4 -  (11 -  ——)  < 0  

              5  

Step  2  :

Rewriting the whole as an Equivalent Fraction :

2.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  5  as the denominator :

          11     11 • 5

    11 =  ——  =  ——————

          1        5    

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

2.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

11 • 5 - (16)     39

—————————————  =  ——

      5           5  

Equation at the end of step  2  :

       39

 -4 -  ——  < 0  

       5  

Step  3  :

Rewriting the whole as an Equivalent Fraction :

3.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  5  as the denominator :

          -4     -4 • 5

    -4 =  ——  =  ——————

          1        5    

Adding fractions that have a common denominator :

3.2       Adding up the two equivalent fractions

-4 • 5 - (39)     -59

—————————————  =  ———

      5            5  

Equation at the end of step  3  :

 -59

 ———  < 0
