P=$222 r=12% Y=10 A=?
sergey [27]
To solve for the A or the principal amount plus interest you can use two formulas:

A = P + I

Where: P = Principal
             I  = Interest

or you can use 

A = P (1+ rt)

Where: P = principal
             r  = rate in decimal
             t  = time in years

With your given you can use the second one, without having to use the first. 
Given that the Principal amount is $222 and the rate is 12% and time is 10 years, we first need to convert your rate into decimal by dividing the value in percent by 100 which will yield 0.12. 

Then now we can just input the data that you know into the formula:
A = P(1+ rt)
   = $222(1 + (0.12)(10))
   = $222(2.2) 
   = $488.40

Your A is then equal to $488.40

If you need to get the simple interest all you need to use is the first formula given:

A = P + I
for the interest you transpose the P to the side of the A and you will get:
I = A - P
  = $488.40 - $222
  = $266.40

$266.40 is the added interest to the principal amount.

Enter your answer in the provided box. what is the emf of a cell consisting of a pb2 / pb half-cell and a pt / h / h2 half-cell
s2008m [1.1K]

The emf of a cell is mathematically given as

E_{cell}  = 0.0532 v

<h3>What is the emf of a cell?</h3>

Generally, the equation for emf  is mathematically given as

Pb/Pb^2^+ //\ H / H_2

where,

Pb is lead

H is hydrogen

Pb^{2+} / Pb has a standard reduction potential of -0.126 volts, while

H_2 / H_2 has a standard reduction potential of 0.0 volts.

E_{cell }= E^0_{cell} - 0.059/n log 1/[Pb^2^+] x [H^+]^2

E_{cell} = 0.126 -  0.059/2 log 1  /  [0.57] x [0.09]^2

E_{cell}  = 0.0532 v

Aubrey's coach asks her to bring 5 liters of water to practice.
fenix001 [56]

Answer:

C

Step-by-step explanation:

This is because a liter is 1000 milliliters, so multiplying the amount of liters to the milliliters you would get 5000, you would then divide that by 500  since a bottle would contain that much, giving you 10 bottles
