let's solve for " w "

  • vw {}^{2}  + y = x

  • vw {}^{2}  = x - y

  • {w}^{2}  =  \dfrac{x - y}{v}

  • w =  \sqrt{ \dfrac{x - y}{v} }

Answer:

w = √( x - y ) / v

Step-by-step explanation:

in this situation, we are actually asked to make w the subject of the formula

this !means that we should make w be equal to every other variable meaning;

w = y + x

note that this is just an example

so, let us get started

we have;

vw² + y = x

first of all we have to move the y to the right hand side

it is more like collecting like terms so that at the end of the day we only end up with w on that side

vw² = x - y

now, we have to remove the ²

we will do that by square rooting both sides

√( vw )² = √( x - y )

the square root will remove the square because they are opposites of each other.

it is more like a multiplication sign canceling a division sign or when we bring a subtraction sign to the other side of the equation and it turns to an addition sign.

in our case, it is like bringing the square to the other side of the equation and it turns to a square root sign

so,

vw = √( x- y )

we ate almost done.

it is now time to remove the v by dividing through by v

this means that we remove the multiplication sign bonding the v and w through division just like the square root removing the square

vw / v = √( x - y ) / v

w = √( x - y ) / v

therefore , our answer is

w = √( x - y ) / v

PSYCHO15rus [73]

Answer:

Sales tax on selling price:  $2232.50(0.03) = $66.98

Step-by-step explanation:

List price:  $2350

5% discount:  0.05($2350) = $117.50

Sale (selling) price:  List price less discount:  $2350 - $117.50 = $2232.50

Sales tax on selling price:  $2232.50(0.03) = $66.98

How many ways are there for 15<br> track runners to win 1st place, 2nd<br> place and 3rd place?
Mkey [24]

Answer:

2730 ways.

Step-by-step explanation:

There are 3 positions to be filled by the 15 runners.

For 1st place, we can fill this position in 15 ways.

After filling 1st place remaining runners = 14

Number 2 place can be filled by remaining 14 runners.

So, the 2nd place can be filled by 14 ways.

Again, after filling 2nd place remaining runners are 13.

Therefore, 3rd place can be filled by 13 ways.

Total number of ways to fill all three places = 15 × 14 × 13

                                                                         = 2730 ways

A custom t shirt company charges a $200 set up fee and $5 per t shirt. Approximately how may t shirts must be produced so that t
dolphi86 [110]
To find the number of t-shirts, we must add the individual cost of producing 1 shirt and equate it to 5.33. Since 200 is the cost of the set-up fee, we divide this by an unknown x, for the individual cost. We add 5, which is the cost to produce a shirt. We now have 200/x + 5 = 5.33. Find the value of x, which is 606, nearest to 600. Therefore approximately 600 t-shirts must be produced.

On 3 and 4, please answer this two question
Hunter-Best [27]

Answer:

3) ½ chance

4) 60 times

Step-by-step explanation:

<h3><u><em>3) Theoretically, if the spinner is spun 150 times</em></u></h3><h3><u><em>how many times would you expect to get an</em></u></h3><h3><u><em>even number?</em></u></h3>

<u><em></em></u>

There are 12 equal sections, getting an even numbers is a ½ chance. ( same as odd numbers)

The probability is ⁶⁄₁₂ or ½.

In addition, this is theoretical probabilty, it doesn't require experiments.

<h3><u><em>4) Based on the experiment, if the spinner is</em></u></h3><h3><u><em>spun 150 times, how many times would you</em></u></h3><h3><u><em>expect to get an even number?</em></u></h3>

Getting a 2: ⁴⁄₆₀ or ¹⁄₁₅

Getting a 4: ³⁄₆₀ or ¹⁄₂₀

Getting a 6: ⁷⁄₆₀

Getting a 8: ³⁄₆₀ or ¹⁄₂₀

Getting a 10: ⁵⁄₆₀ or ¹⁄₁₂

Getting a 12: ²⁄₆₀ or ¹⁄₃₀

Chance of picking a even number using 60 tries:

⁴⁄₆₀ + ³⁄₆₀ + ⁷⁄₆₀ + ³⁄₆₀ + ⁵⁄₆₀ + ²⁄₆₀ = ⁴ ⁺ ³ ⁺ ⁷ ⁺ ³ ⁺ ⁵ ⁺ ²⁄₆₀ = ²⁴⁄₆₀ or ⅖

Picking a even number using 150 tries:

⅖ · 150 = 60 times
