Answer:

35%

Step-by-step explanation:

Find out what percent 91 is of 140

91÷140 = 0.65

Then find out how much was reduced by subracting 0.65 from 1

1 - 0.65 =0.35

The coat was reduced by 35%

Find the possible values of k if one of the roots of the quadratic equation x^2 - kx + 8 = 0 is twice the other.

kondor19780726 [428]

Answer:

$k=\pm 6$

Step-by-step explanation:

The given quadratic equation is :

$x^2 - kx + 8 = 0$

One of the roots of this equation is twice that of the other. Let the roots are $\alpha \ and\ \beta$ , $\alpha =2\beta$

Sum of roots, $\alpha +\beta =\dfrac{-b}{a}$

$\alpha +\beta =\dfrac{-(-k)}{1}\\\\\alpha +\beta =k\\\\3\beta =k\ .......(1)$

Product of roots,

$\alpha \beta =\dfrac{c}{a}\\\\2\beta ^2=\dfrac{8}{1}\\\\\beta =\pm 2$

If $\beta =\pm2$ ,

$k=3(2)\\\\=\pm 6$

So, the value of k is equal to $\pm 6$ .

Answer:

25 ft

Step-by-step explanation:

The volume is given by the formula ...

V = LWD . . . . . the product of length, width, depth

Solving for L, we have ...

L = V/(WD) = (1700 ft³)/((17 ft)(4 ft)) = 100/4 ft = 25 ft

The length of the pool is 25 ft.
