A person places $531 in an investment account earning an annual rate of 6.1%,

compounded continuously. Using the formula V = = Pent, where V is the value of the

account in tyears, P is the principal initially invested, e is the base of a natural

logarithm, and r is the rate of interest, determine the amount of money, to the

nearest cent, in the account after 16 years.

Answers

Answer:

$1408.74

Step-by-step explanation:

Given data

P= $531

T= 16 year

R= 6.1%

We are given the expression

[tex]V= Pe^r^t[/tex]

Required

the final amount V

substituting our data into the expression

[tex]V=531*e^{0.061*16}\\\\V=531*e^{0.976}\\\\V=531*2.653\\\\V=1408.743[/tex]

Hence the amount of money is $1408.74

8.) Anthony goes to lunch with his friends. His portion of the bill is $20. He
wants to leave the waitress a 20% tip. How much would he leave for a tip?

Answers

Answer:

23.00

Step-by-step explanation:

If you want to leave a 20% tip, multiply the cost by 0.20 to get the tip amount or multiply the cost by 1.20 to get the total including tip. If you want to leave a 18% tip, multiply the cost by 0.18 to get the tip amount or multiply the cost by 1.18 to get the total including tip.

Answer: Anthony should leave a $4 tip.

Step-by-step explanation:

20% = 0.2

So, multiply $20 × 0.2 = $4

The sum of two numbers is 369 the difference of those two numbers is 17 which answer choice shows both numbers

Answers

Answer:

(176, 193)

Step-by-step explanation:

Well you forgot to put in the choices, but:

The difference between the numbers is 17. Let's call the smaller number x and the bigger one y

(x + y) = 369

y = x + 17

(x + (x + 17)) = 369

2x + 17 = 369

2x = 352

x = 176

y = x + 17 = 193

X=193,y=176
X+y=369
X-y=17
X=17+y
(17+y)+y=369
17+2y=369
2y=352
Y=176
X=369-176
X=193

What is the solution to the system of equations?

Answers

Answer:

(3, -2)

Step-by-step explanation:

both of the equations are equal to y, which means they are equal to each other.

So you write them as equation(1) = equation(2)

and solve for x.

Next substitute the value of x to any of the equations and find y. And that is how I got (3 , -2)

Answer: 1) 530.66 ft^2

Step-by-step explanation:

You need to find the area of the circles.

They gave you the formula to find them which is

Area = Pi * R^2    //// Pi times Radius squared will give you the area.

For example, the radius of the 1st question is 13ft. We use it with the formula given.

A = 3.14 * 13^2  /// 13 squared is just 13 x 13 = 169

A = 3.14 * 169   /// Now multiply Pi times 169

A = 530.66      /// Thats your answer.

Anna is following this recipe to make biscuits.
Anna uses 660 mL of syrup.
How many grams of margarine will she need?

Recipe: Makes 24 biscuits
60 g sugar
110 mL syrup
220 g oats
120 g margarine
40 g chocolate​

Answers

Answer:

720 grams

Step-by-step explanation:

660 mL(amount she used) / 110 mL (amount from the recipe) = 6 times

So Anna uses 6 times the amount of syrup from the recipe.

Therefore she also needs 6 times more margarine than it is written in the recipe, which is 120 g * 6 = 720 g

Answers

Answer:

Step-by-step explanation:

Equations

Ron and Howard work at Amazon.

Ron works x hours each week for 7 days. This means he works 7x hours a week.

Howard works one more hour per day than Ron, thus he works x+1 hours per day. This means he works 7(x+1)=7x+7 hours a week.

Howard works 7x+7 hours in a week
