If Debbie starts a retirement account with 10,000 dollars that has an annual rate of return of 12%, how long (in years) would it take for her to have at least 100,000 dollars if interest is compounded continuously?

Answers

Answer:

19.2 years

Step-by-step explanation:

The formula to find the time in a compound interest that is compounded continuously is given as:

t = ln(A/P) / r

Where:

t = time in years = ??

A = Amount after Interest is compounded continuously = $100,000

P = Initial Amount in the retirement account = $10,000

r = Rate of return = 12%

First, convert R percent to r a decimal

r = R/100

r = 12%/100

r = 0.12 per year,

Then, solve our equation for t

t = ln(A/P) / r

t = ln(100,000.00/10,000.00) / 0.12

t = 19.188 years

Approximately t = 19.2 years

Barky's animal shelter has a total of 15
Chihuahuas and Yorkies. There are four
times as many Chihuahuas as Yorkies.
Using c for Chihuahuas and y for Yorkies,
determine which equation may be
used to represent this situation.
c=4+y
y=4+c
y=4c
c=4y

Answers

Answer:

c = 4y

Step-by-step explanation:

Are there more, Chihuahuas or Yorkies?

Does  the word 'times' mean add, subtract, multiply or divide?

The way I look at it,  there are more Chihuahuas and 'times' means multiply.  Do you agree?

Therefore, I need to multiply 4 times the no. of Yorkies to get the no. of Chihuahuas

So,  c = 4y

Now, I don't see an equation in the list to choose from.  So, I don't know what to do from here.  I am guessing that c = 4y is what you want.

Chazmire purchases 14 bags of flour for her bakery.Each bag of flour cost $2.47. How much does chazmire soend for flout

Answers

Answer:

$34.58

Step-by-step explanation:

If each bag of flour cost $2.47, then;

1 bag = $2.47

To calculate the cost of 14bags;

14 bags = x

x is the cost of 14 bags

Divide both expressions

1/14 = 2.47/x

cross multiply

1 * x = 14 * 2.47

x = $34.58

Hence Chazmire spent $34.58 on flour

PLEASE HELP ME ASAP(WORTH 30 POINTS). If the domain is {0, 2, -6}, what is the range of y = -2x + 3?

Answers

Answer:

Range = {3, -1, 15}

Step-by-step explanation:

Domain = {0,2,-6}

function : y= -2x + 3

We replace the value of x with domain,

when x = 0

y = -2 × 0 + 3

y = 3

When x = 2

y = -2 × 2 + 3

y = -1

When x = -6

y = -2 × -6 + 3

y= 12 + 3

y = 15

Rhett decides to build a square room for his movie and music collection. If the area of the room is 4x2 + 28x + 49 square feet, what is the length of one side of the room?

(7x + 2) feet
(2x + 7) feet
(2x − 7) feet
(7x − 2) feet

Answers

Answer:

(2x + 7) feet

Step-by-step explanation:

I'm guessing the expression there is

4x² + 28x + 49

4x² +14x +14x +49

Factorize

2x ( 2x + 7) +7( 2x + 7)

(2x + 7)²

Area = (side)1

One side is (2x +7)

Anyone know the answer to this problem (find the values of x and y)

Answers

Answer:

y = 8

x = 4

Step-by-step explanation:

This is a special right triangle with angle measures of 90 60 30 and the side lengths are represented by a - a√3 - 2a

The side length that sees angle measure 30 is a

The side length that sees angle measure 60 is a√3

The side length that sees angle measure 90 is 2a

if the side length that sees angle measure 60 is given as 4√3 then that means a = 4

so x = 4 and 2x = 8
