Margaret’s bottle of shampoo is 7/8 full. She uses 1/3 of the shampoo in the bottle to wash the dog. Estimate what fraction of s
AleksandrR [38]

Fraction of shampoo left = \frac{13}{24}

Solution:

Given fraction of full shampoo  =\frac{7}{8}.

Fraction of shampoo Margaret used  =\frac{1}{3}

Fraction of shampoo left = Full shampoo – fraction of shampoo used

                                          =\frac{7}{8}-\frac{1}{3}

To make the denominators same do cross multiplication.

                                          =\frac{7\times3}{8\times3}-\frac{1\times8}{3\times8}

                                          =\frac{21}{24}-\frac{8}{24}

                                          =\frac{21-8}{24}

                                          =\frac{13}{24}

Hence \frac{13}{24} of the shampoo bottle is left.

The equation of a parabola is given.
BlackZzzverrR [31]

Answer:

Directrix equation:  y = 11/2

y = k - c = 6 - 1/2 = 11/2

Step-by-step explanation:

y=(1/2) x^2+6x+24

factor this

y =  (1/2)* [  x^2  + 12x  ]  +  24

y =  (1/2)* [  x^2  + 12x  + 36  -  36]  +  24

y =  (1/2)* [  (x + 6)^2  -  36]  +  24

y =  (1/2)*   (x + 6)^2  - 18 +  24

y =  (1/2)*   (x + 6)^2  + 6

y - 6 =  (1/2)*   (x + 6)^2

2*(y - 6)  =   (x + 6)^2

4c = 2,   (h, k) = (-6, 6)

c = 1/2

Directrix equation:  y = k - c = 6 - 1/2 = 11/2
