Ad A shows the vehicle priced at twenty-four thousand two hundred dollars at six point five percent interest and an unknown number of years. Ad B shows an unknown price, at a five point three percent interest over nine years. Question 1 Part A Regina calculates that to buy the car in Ad A, the loan would ultimately cost her $41,503. Over how many years is the loan in Ad A to be paid back?

Answers

Answer:

11 years

Step-by-step explanation:

Given that:

Advert A:

Principal, p = $24,200

Interest rate, r = 6.5% = 6.5/100 = 0.065

Time, t =?

Total Repayment, A = $41,503

Using the relation :

A = p(1 + rt)

Plugging our values

41503 = 24200(1 + 0.065t)

41503 / 24200 = 1 + 0.065t

1.715 = 1 + 0.065t

1.715 - 1 = 0.065t

0.715 = 0.065t

t = 0.715 / 0.065

t = 11 years

Loan in Advert A will be paid back in 11 years

Answer:

11 years

Step-by-step explanation:

1.715 - 1 = 0.065t

A quantity with an initial value of 230 decays continuously at a rate of 7% per year. What is the value of the quantity after 8.7 decades, to the nearest hundredth?


The answer is ≈0.52

Answers

Answer:

≈0.52

Step-by-step explanation:

The value of the quantity after 8.7 decades is 0.521.

What is Exponential Growth and Decay?

Exponential growth is the increase of rate of change and thus results in the increase of the final quantity.

Exponential decay is the decrease in rate of change and hence results in the decrease of the final quantity.

Given that,

Initial value of the quantity = 230

Rate of decay = 7% per year = 0.07

Time = 8.7 decades = 87 years

The formula for exponential decay is,

A = P e^(-k t)

Here A is the final value of the quantity

P is the initial value of the quantity

k is the decay rate

t is the time.

Substituting the given values,

A = 230 × e^(-0.07 × 87)

A = 230 × e^(-6.09)

   = 0.521

Hence the final quantity after 8.7 decades is 0.521.

mary ann spent $26.85 total on two new toys. She had a coupon for 1.00 off her total purchase and spend 1.75 on sales tax. Each toy cost the same amount how much did each toy cost?

Answers

Answer: $13.80

Step-by-step explanation:

Mary ann spent $26.85 total on two new toys but had a coupon for $1.00 off her total purchase. Therefore, we subtract $1.00 from $26.85. This will be:

= $26.85 - $1.00

= $25.85

Shw then spend $1.75 on sales tax. Total coat will now be:

= $25.85 + $1.75

= $27.60

Since each toy coat same amount, therefore each toy will cost:

= $27.60 / 2

= $13.80

A petri dish of bacteria grow continuously at a rate of 200% each day. If the petri dish began

function f(t) = ger and give your answer to the nearest whole number. Show your work.

Need the answer ASAP

Answers

Answer: 2430 bacteria.

Step-by-step explanation:

When we have a quantity A, and we have an increase of the X%, the new quantity can be written as:

A + (X%/100%)*A

In this case, we have A = 10 bacteria.

And X% = 200%.

Then if we start with 10 bacteria.

After one day, we will have:

10 bacteria  + (200%/100%)*10 bacteria

= 10 bacteria + 2*10 bacteria = 3*10 bacteria.

After another day, we will have:

3*10 bacteria + (200%/100%)*(3*10 bacteria)

3*10 bacteria  + 2*(3*10 bacteria)

3*(3*10 bacteria)

10 bacteria*(3)^2

We already can see the pattern here.

After t days, we will have:

10 bacteria*(3)^t.

This is the equation f(t) we wanted:

f(t) =10 bacteria*(3)^t

after 5 days, we will have:

f(5) = 10 bacteria*(3)^5 = 2430 bacteria.

To our left, we have an unshaded circle at -3. This means that -3 is included in the possible value of x. And as such, we can say -3 < x.

To our right, we have a shaded circle at 1. This means 1 is included in the possible values of x. And as such, we can say x ≤ 1.

Thus, we can represent the two statements as one, thus:

Step-by-step explanation:

First, you make it into a fraction. So because percents are out of 100, it would be 168/100. Then, you take 100 out of it to get a mixed number, 1 and 68/100, and then simplify 68/100 by dividing both sides by the greatest common factor, which is 4. 68/100÷4=17/25. The answer would be 1 and 17/25.

Why is 16 the answer to 10. x / 2 - 5 = 3? I need an answer today.

Answers

Hi there!

[tex]\large\boxed{x = 16}[/tex]

x / 2 - 5 = 3

Begin by adding 5 to both sides to isolate for x:

x / 2 - 5 + 5 = 3 + 5

x / 2 = 8

Multiply both sides by 2 to have "x" alone on the left-hand side:

(x / 2) × 2 = 8 × 2

x = 16

Answer:

because if x is 16

16/2 = 8 and so on 8 - 5= 3 so that is the answer

In one town, 47% of all voters are Democrats. If three
voters are randomly selected for a survey, what is the
probability that they are all Democrats?

Answers

Answer:

The  probability that the all three votes are  Democrats

P(X=3) = 0.1038

Step-by-step explanation:

Step(i):-

Given that the all voters are democrats

The probability that the all voters are democrats

p = 47% =0.47

q = 1-p =1-0.47 = 0.53

Step(ii):-

Let 'X' be the random variable in binomial distribution

[tex]P(X=r) = n_{C_{r} } p^{r} q^{n-r}[/tex]

The  probability that the all three votes are  Democrats

P(X=3) = 0.1038

n=3 and r=3

[tex]P(X=3) = 3_{C_{3} } (0.47)^{3} (0.53)^{3-3}[/tex]

[tex]P(X=3) = 1 (0.47)^{3}[/tex]

P(X=3) = 0.1038

Final answer:-

The  probability that the all three votes are  Democrats

P(X=3) = 0.1038

A local courier service estimates its monthly operating costs to be $1500 plus $0.85 per delivery. The service generates revenue of $6 for each delivery. Let x = the number of deliveries in a given month. The function C(x) = .85x + 1500 represents the operating cost. The function R(x) = 6x represents the revenue generated. Knowing that profit = revenue - cost, write a function, P(x), that represents the monthly profits for making x deliveries per month.​

Answers

Answer:

P(x) = 5.15 x + 1500

Step-by-step explanation:

The monthly operating costs = $1500 plus $0.85 per delivery.

The service generates revenue= $6 for each delivery

If in a given month the deliveries number was = x  then;

Operating cost  function : C(x) = 0.85x + 1500

Revenue generated function R(x) = 6x

Profit = Revenue - cost

P(x) = R(x) - C(x)

P(x) = 6x - 0.85x + 1500

P(x) = 5.15 x + 1500
