Answer:

V=1.17 v

Step-by-step explanation:

The difference in potential between two points can be described as: potencial of the iron less  potential of the zinc, that is: V= 0.76-(-0.41)

Which can be rewrite as: V= 0.76 v + 0.41 v

V=1.17 v

Answer:

Step-by-step explanation:

In a redox reaction involving Iron and Zinc, the Zinc will serve as the anode, and Iron the cathode. The zinc anode will oxidize and provide electrons for the reduction of Fe2+(aq) to elemental iron.

E°cell = E°cathode - E°anode

= 0.76 - (-0.41)

= +1.17 V

Consider a student loan of $12, 500 at a fixed APR rate of 9% for 25 years.
Eduardwww [97]

The monthly payment is; $104.9; The total amount paid over the term of the loan is; $31470

<h3>How to calculate APR?</h3>

We are given;

Loan principal = $12,500

Interest rate = 12%

Number of payments per year = 12 payments per year.

Loan term = 25 years.

Formula for monthly payment is;

PMT = (p * APR/n)/[1 - (1 + APR/n)^(-nY)]

Where;

p is principal

APR is interest rate

n is number of payments per year

Y is loan term

Thus;

PMT = (12500 * 0.09/12)/[1 - (1 + 0.09/12)^(-12 * 25)]

PMT = 93.75/(1 - 0.106288)

PMT = $104.9

B) Total amount paid over the loan term is;

A = PMT * m * n

where;

m is number of months in a year,

n is number of years

A = 104.9 * 12 * 25

A = $31470

C) The principal as a percentage of the loan is;

P/A = 12500/31470

P/A = 39.72%

Percentage paid for interest is = 100% - 39.72% = 80.28%

Mike measured the stage where his band was going to play to determine if it is a right triangle. Does the stage with side length
katrin [286]

Answer:

let

hypotenuse[h]=60ft

base[b]=36ft

perpendicular [p]=48ft

by using Pythagoras law

p²+b²=h²

48²+36²=60²

2896≠3600

since p²+b²≠ h²[<u>so</u><u> </u><u>the</u><u> </u><u>stage</u><u> </u><u>is</u><u> </u><u>not</u><u> </u><u>in</u><u> </u><u>a</u><u> </u><u>right</u><u> </u><u>angled</u><u> </u><u>tria</u><u>ngle</u><u>]</u><u>but</u><u> </u><u>it</u><u> </u><u>is</u><u> </u><u>scalene</u><u> </u><u>triangle</u>
