Between what two integers is √95?

andrey2020 [161]

Answer:

Between 9 and 10.

Step-by-step explanation:

We know that √81 = 9 and that √100 = 10.

Since √95 is between √81 and √100, we know it will be between 9 and 10.

√95 = 9.74679

If ∠A and ∠B are supplementary and m∠A = 37°45', then m∠B = ______.

xenn [34]

Answer: 142°15'

Explanation:

Supplementary angles are angles that add up to make a straight angle ( $180^{\circ}$ ).

Therefore, we must find the angle ∠B such that

∠A + ∠B = 180° (1)

We know that ∠A = 37°45', so we can re-arrange equation (1) to find the magnitude of ∠B:

∠B = 180° - ∠A = 180° - 37°45' = 142°15'

So, the correct answer is

142°15'

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

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
