Skylar plans to use $3400 to open a savings account with an annual interest rate of 1.15%. How much more interest will he earn o

erik [133]

Given
Present investment, P = 3400
APR, r = 0.0115
compounding time = 13 years
Future amount, A

A. compounded annually
n=13*1=13
i=r=0.0114
A=P(1+i)^n
=3400*(1+0.0115)^13
=3944.895

B. compounded quarterly
n=13*4=52
i=r/4=0.0115/4
A=P(1+i)^n
=3400*(1+0.0115/4)^52
=3947.415

Therefore, by compounding quarterly, he will get, at the end of 13 years investment, an additional amount of

A number plus itself, plus twice itslef, plus 4 times itself, is equal to -104. what is the number?

Nutka1998 [239]

Let's represent this unknown number with the variable 'n'
n + n + 2n + 4n = -104

Explanations:
'n+n' - a number plus itself
'+2n' - plus twice itself
'+4n' - plus 4 times itself

Anyway:
n + n + 2n + 4n = -104
Simplify:
8n = -104
Divide both sides by 8:
n = -13

The number is -13
Good luck! If you need me to explain something in more depth, just ask :))

Question 1 2 pts Logic Puzzle: A certain clock runs fast; it indicates that 1 hour has passed when actually only 56 minutes have

Liono4ka [1.6K]

Using proportions, it is found that the correct time when it reads 10:30pm is of 9:40 pm.

<h3>What is a proportion?</h3>

A proportion is a fraction of total amount, and the measures are related using a rule of three.

In this problem, when 56 minutes have passed, the clock indicates that 60 minutes have passed. Hence, what is the time passed when the clock indicates that 12 hours and 30 minutes, that is, 60 x 12 + 30 = 750 minutes have passed?

Hence, the <em>rule of three</em> is:

56 minutes - 60 minutes

x minutes - 750 minutes

Applying cross multiplication:

$60x = 56 \times 750$

$x = \frac{56 \times 750}{60}$

$x = 700$

700 minutes is 660/60 = 11 hours + 40 minutes after 10:00 am, hence the correct time is of 9:40 pm.
