Answer:

Number of boxes that will fit =2340

Step-by-step explanation:

The shipping box volume can be calculated by the formula V = Lxwxh ,where L ,w ,h are length ,width and height of the box.

The length of the shipping box = $3\frac{3}{4} =\frac{15}{4} ft.$

Width = 3 ft.

Height = $3\frac{1}{4} =\frac{13}{4} ft.$

Volume of shipping box = $\frac{15}{4} .3 .\frac{13}{4} =\frac{585}{16} = 36.6 ft$ .cubic ft.

Volume of shipping box can also be calculated by multiplying base area with the height of box.

Base area of box = $\frac{15}{4} .3=\frac{45}{4} square ft.$

Volume of box = base area x height = $\frac{45}{4} .\frac{13}{4} = 36.6 cubic ft.$

Volume of packing cubes = $\frac{1}{4} .\frac{1}{4} .\frac{1}{4} =\frac{1}{64}$ cubic ft.

Number of fish boxes that will fit in the shipping box = volume of shipping box ÷ volume of fish food box = 36.6 ÷ $\frac{1}{64}$ =2340 .

of the 125 guests invited to a wedding ,104 attended the wedding .What percent of the invited guests attended the wedding

pashok25 [27]

$\frac{104}{125} =\frac{104\times8}{125\times8}=\frac{832}{1000}$

832/1000 = 0.832 = 0.832 * 100% = 83.2%

83.2% of the invited guests attended the wedding.

What are the solutions of x^2-2x+5=0

sweet [91]

The solution of $x^{2}-2 x+5=0$ are 1 + 2i and 1 – 2i

Solution:

Given, equation is $x^{2}-2 x+5=0$

We have to find the roots of the given quadratic equation

Now, let us use the quadratic formula

$x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}$ --- (1)

Let us determine the nature of roots:

Here in $x^{2}-2 x+5=0$ a = 1 ; b = -2 ; c = 5

$b^2 - 4ac = 2^2 - 4(1)(5) = 4 - 20 = -16$

Since $b^2 - 4ac < 0$ , the roots obtained will be complex conjugates.

Now plug in values in eqn 1, we get,

$x=\frac{-(-2) \pm \sqrt{(-2)^{2}-4 \times 1 \times 5}}{2 \times 1}$

On solving we get,

$x=\frac{2 \pm \sqrt{4-20}}{2}$

$x=\frac{2 \pm \sqrt{-16}}{2}$

$x=\frac{2 \pm \sqrt{16} \times \sqrt{-1}}{2}$

we know that square root of -1 is "i" which is a complex number

$\begin{array}{l}{\mathrm{x}=\frac{2 \pm 4 i}{2}} \\\\ {\mathrm{x}=1 \pm 2 i}\end{array}$

Hence, the roots of the given quadratic equation are 1 + 2i and 1 – 2i

Answer:

10 sqrt(3)/3 =x

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

tan theta = opp side /adj side

tan 30 = x/10

10 tan 30 =x

10 ( sqrt(3)/3) = x

10 sqrt(3)/3 =x
