A new car is purchased for $50,000 and over time it’s value depreciates by one half every 5 years. What is the value of the car

Setler79 [48]

The value of the car after 5 years would be $23914.85

<u>Explanation:</u>

Given:

Worth of the new car = $50,000

Every 5 years the value depreciates by 1/2

i.e., every 5 years the value depreciates by 50%

So, we can say that every year the value depreciates by 10%

The worth of the car after 7 years would be

$W = C (1 - \frac{D}{100} )^t$

where,

W is the depreciated value

C is the current value

D is the depreciation rate

t is the time

Substituting the value in the equation we get:

$W = 50000( 1 - \frac{10}{100} )^7\\\\W = 50000 (\frac{9}{10} )^7\\\\W = 23914.85$

Therefore, the value of the car after 5 years would be $23914.85

A 20kg patient requires a 500 mg dose of a particular drug solution contains 100 mg/tsp. How many milliliters of the solution sh

Annette [7]

Answer:

The answer is "25 ml".

Step-by-step explanation:

Dose $= 500 \ mg\\\\$

Solution $= 100\ \frac{mg}{teaspoonful}\\\\$

Calculating the Conversions:

Teaspoonful $= 5 \ ml \ \text{(Ounce = 30 ml = 6 Tablespoonsful)}$

$\therefore\\\\Solution = \frac{100\ mg}{ 5\ ml} = 20\ \frac{mg}{ml}\\\\Dose \ volume = \frac{500\ mg}{ 20\ \frac{mg}{ml}} = 25\ ml$

I need to show work..

nika2105 [10]

Answer:

$13x - 4 = 8x + 11 \\ 13x - 8x = 4 + 11 \\ 5x = 15 \\ \frac{5x}{5} = \frac{15}{5} \\ x = 3$

NOW LET'S FIND THE VALUE OF AD

$ad \: \: length = 13x - 4 \\ \\ x = 3 \\ \\ 13x - 4 \\ 13 \times 3 - 4 \\ 39 - 4 \\ = 35$
