using compound interest, how long does it take to double a 1000 dollar investment that pays 6.5% annual interest, compounded monthly?​

Answers

Answer 1

Answer:

11 years approx

Step-by-step explanation:

Given data

P=$1000

A=2000

R=6.5%

T= ?

Calculate time, solve for t

t = ln(A/P) / r

substitute

t=ln(2000/1000)/0.065

t=ln(2)/0.065

t=0.693/0.065

t=10.66

Hence the time is 11 years approx

What is the value of the x ? x + x + x = 56

Answers

x = 56 divided by 3 = 18.6

Hey there!

ORIGINAL EQUATION

x + x + x = 56

CONVERT/COMBINE the LIKE TERMS

1x + 1x + 1x = 56
2x + 1x = 56

NEW EQUATION

3x = 56

DIVIDE 3 to BOTH SIDES

3x/3 = 56/3


SIMPLIFY IT by canceling out 3/3 because it give you 1 & KEEP 56/3 because help solve for the x-value (it also give you the x-value result)


x = 56/3

x = 18.666667

x = 18 2/3


EITHER OF THOSE SHOULD WORK BECAUSE THEY ARE ALL EQUIVALENT TO EACH OTHER

Good luck on your assignment & enjoy your day!

An African elephant weighed 209 lbs when it was born. Baby elephants gain an average of 38 lbs per week.
How many weeks will it take for the baby elephant to weigh 1197lbs?

Answers

Let the number of weeks be x
38x + 209 = 1197
Subtract 209 on both sides
38x = 1197
Divide 38 on both sides
x = 31.5 weeks

many days does Torì need to spend making jam if she wants to jar 10 liters of jam in all?

Answers

Answer:

9 days.
