Step-by-step explanation:

to find how much one pound of potatoes is, you have to divide the the cost of the bad by the number of pounds ($3.98 divided by 10 pounds)

$3.98 : 10 = $0.398 = $0.40

Hello there! The value of x is 20 or -20

"20 or - 20" is one answer so you are supposed to answer 20 or -20, not choose only one.

Step-by-step explanation:

$\large{ \frac{ {x}^{2} }{ {5}^{2} } = {4}^{2} }$

First, we simplify 5² and 4²

$\large{ \frac{ {x}^{2} }{25} = 16}$

Multiply the whole equation by 25 to get rid of the denominator.

$\large{ \frac{ {x}^{2} }{25} (25) = 16(25)} \\ \large{ {x}^{2} = 400}$

Square both sides and solve the equation.

$\large{ \sqrt{ {x}^{2} } = \pm{ \sqrt{400} }}$

Also don't forget to write "plus or minus" symbol when we are solving a quadratic equation by squaring both sides.

$\large{x = \pm{20}}$

Sarah competes in a long jump competition Her first jump is 4.25m Her best jump is 12% more than this However, her best jump is

ad-work [718]

>First jump = 4.25 m

>Best jump = 1.12 * First jump

Best jump = 1.12 * (4.25 m)

Best jump = 4.76 m

>Best jump = 0.85 * Winning jump

Hence,

Winning jump = Best jump / 0.85

Winning jump = 4.76 m / 0.85

Winning jump = 5.6 m

Find the volume of the composite solid.

OLEGan [10]

Here's the solution,

the volume of the given figure is :

=》

$volume \: \: of \: \: (pyramid \: + rectangular \: \: prism)$

volume of pyramid :

=》

$\dfrac{l \times b \times h}{3}$

=》

$\dfrac{4 \times 5 \times 6}{3}$

=》

$\dfrac{120}{3}$

=》

$40$

volume of pyramid = 40 cm³

now, volume of rectangular prism :

=》

$l \times b \times h$

=》

$4 \times 5 \times 2$

=》

$40$

volume of rectangular prism = 40 cm³

volume of composite figure = 40 + 40

=》80 cm³
