The value of a car with an initial purchase price of $15,250 depreciates by 16% per year. How much is the car worth after 6 year

Scrat [10]

Answer:

$13842.43

Step-by-step explanation:

Given data

Value of car=$15,250

Rate of depreciation= 16%

Time = 6 years

We can use the exponential function below to model the value of the car after 6 years

v(t)= a(r)^x

But r= 1-0.016----------Because the value is depreciating

a=15,250

r=0.016

x=6

Substitute

v(t)= 15250(1-0.016)^6

v(t)= 15250(0.984)^6

v(t)= 15250*0.9077

v(t)= $13842.43

Hence the value will be $13842.43 after 6 years

What is the value of x when y equals 2 in the equation y equals x over 4 - 7

Alex

The value of x when y = 2 is x = 36

Step-by-step explanation:

The equation that we have in this problem is:

$y=\frac{x}{4}-7$

In order to find the value of x when y is equal to

y = 2

We need to re-arrange the equation making x the subject.

We proceed as follows:

1) We add +7 on both sides:

$y+7=\frac{x}{4}-7+7\\y+7=\frac{x}{4}$

2) Now we multiply both sides by 4:

$4(y+7)=\frac{x}{4}\cdot 4\\x=4(y+7)$

3) Now we can substitute y = 2 and find the value of x:

$x=4(2+7)=4(9)=36$

What is the percentage of cacao in hot chocolate which is made of 480 grams of milk and 20 grams of cacao?

galina1969 [7]

Given that the hot chocolate is made of 480 grams of milk and 20 grams of cacao.

We need to determine the percentage of cacao in hot chocolate.

<u>The percentage of cacao:</u>

The total grams of hot chocolate can be determined by adding the total grams of milk and the total grams of cacao.

Total grams of hot chocolate = Grams of Milk + Grams of cacao

Total grams of hot chocolate = 480 + 20 = 500 grams.

Thus, the total grams of hot chocolate is 500 grams.

Now, we shall find the percentage of cacao.

The percentage of cacao is given by

$\frac{100}{500}\times 20$

Simplifying, the values, we get,

$\frac{2000}{500}=4\%$

Thus, the percentage of cacao is 4%
