Solve for the formula for the indicated variable. Solve A=1/2bh for b.

choli [55]

B = 2A/h

The way you would get this is first by clearing the fraction. So in order to clear the fraction, you have to multiply the equation by the denominator.

2(A = 1/2bh)

2A = 1bh

2A = bh

Then you have to isolate the variable. So you'd divide bh by h in order to get b by itself. So you'd end up with:

2A/h = bh/h

2A/h = b

ABC and ACD are both right angled triangles

emmasim [6.3K]

Answer:

a. Pythagorous theorem

b. 13.9 cm

Step-by-step explanation:

a. By pythagorous theorem,

AC = $\sqrt{12^{2} + 5^{2}}$ cm = 13 cm

b. By pythagorous theorem,

AD = $\sqrt{13^{2}+5^{2}}$ cm = 13.9 cm

0.6 umol/L to g/L conversion please.

Mamont248 [21]

Answer:

FOR H_2

$1 \mu mol/L = 2\times 10^{-6} mol/L$

Step-by-step explanation:

Given data:

concentration $0.6 \mu mol/L$

WE KNOW THAT

$ONE\ \mu = 10^{-6}$

therefore

$1 \mu mol/L = 10^{-6} mol/L$

Now for conversion of mol to gram need the molar mass of element in which particular value convert to.

let us take $H_2$

we know that molar mass of $H_2$ is 2 gram

therefore

$1 \mu mol/L = 2\times 10^{-6} mol/L$

let take other example, for $O_2$

we know that molar mass of O_2 is 32 gram

therefore

$1 \mu mol/L = 32\times 10^{-6} mol/L$
