A family plans a road trip from Fairbanks to Newbury. The distance between the two cities is 240 miles when traveling on the hig

alex41 [277]

Using proportions, it is found that the family will drive 482.8 km on the new route.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, the family travels a distance of 125% of 240 miles, hence the distance is:

D = 1.25 x 240 = 300 miles.

Since there are are approximately <u>48.28 kilometers in 30 miles</u>, and 300/30 = 10, the distance in kilometers is given by:

D = 48.28 x 10 = 482.8 km.

a new car, originally worth $35,795, depreciates at a rate of 17% per year. The value of the car can be represented by the equat

Sergio [31]

We have been given that a new car, originally worth $35,795, depreciates at a rate of 17% per year. The value of the car can be represented by the equation $y=35795(0.83)^x$ , where x represents the number of years since purchase and y represents the value (in dollars) of the car.

To find the value of car of after 5 years, we will substitute $x=5$ in our given equation as:

$y=35795(0.83)^5$

$y=35795\cdot (0.3939040643)$

$y=14099.79598$

Upon rounding to nearest tenth, we will get:

$y\approx 14099.8$

Therefore, the car will be worth $14,099.8 after 5 years it is first purchased.

Since $14,099.8 is less than original value of car, therefore, we know hat value of car is depreciating and $14,099.8 is correct answer.

We also know that an exponential decay function is in form $y=a(1-r)^x$ , where,

y = Final value after t years,

a = Initial value,

r = Decay rate in decimal form,

x= Time.

$17\%=\frac{17}{100}=0.17$

$y=35795(1-0.17)^x$

$y=35795(0.83)^x$

A grocer wants to make a 10-pound mixture of peanuts and cashews that he can sell for $4.75 per pound. If peanuts cost $4.00 per

timofeeve [1]

3 lbs of Cashews, and 7 lbs of Peanuts

$4.00P + 6.50C = ($4.75/lbs)(10lbs)
$4.00(7) + $6.50(3) = $47.50
$28.00 + $19.50 = $47.50
$47.50 = $47.50

Therefore it's 3lbs of Cashews
