The emf of a cell is mathematically given as
= 0.0532 v
<h3>What is the emf of a cell?</h3>
Generally, the equation for emf is mathematically given as

where,
Pb is lead
H is hydrogen
/ Pb has a standard reduction potential of -0.126 volts, while
/
has a standard reduction potential of 0.0 volts.

![[Pb^2^+] x [H^+]^2](https://tex.z-dn.net/?f=%5BPb%5E2%5E%2B%5D%20x%20%5BH%5E%2B%5D%5E2)
= 0.126 - 0.059/2 log 1 / [0.57] x [0.09]^2
= 0.0532 v

Answer:
D. No, there isn’t enough information because only two pairs of corresponding sides can't be used to prove that two triangles are congruent.
2560/5 would be 512 as a fraction with the same denominatir
So we know that the decimal place will move one right. Well basically let's assume she could have bought these expressions:
x 10 x 3.50 = 35.00
x 9 x 3.50 = 31.50 + 3.75 = 35.25
x 8 x 3.5 = 28 + 3.75 x 2 = 35.5
x 7 x 3.5 = 24.5 + 3.75 x 35.75
We know that there is a pattern. See how the cents goes .25 up each time. So we know she'd buy 6 reams of white because (6 x 3.5 = 21) + (4 x 3.75 = 15) = 36.
