Since there are no actual values, I guess we just have to isolate the b.

2A=bh (multiply both sides by 2)
2A/h=b (divide by h)

hope this helps

If x + y = 5 and at the same time 2x - y = 7. find the value of x
Fed [463]

Answer:

x = 2y − 2

Step-by-step explanation:

x + y + 5 = 2x - y + 7

−x + y + 5 = −y + 7

−x + 5 = −2y +7

−x = −2y + 2

x = 2y − 2

Situation:
Arturiano [62]

Answer:

t = 6162  years

Step-by-step explanation:

Apparently you are asked to use the constant k = 0.0001 instead of the most common 0.00012. We'll answer the problem using such number you typed, but make sure that there is no omission in your typing.

The equation to use is that for carbon decay:

N(t)=N_0\,e^{-0.0001\,\,t}

If the skull contains 54% of its original amount of C14, then that means that :

N(t)=0.54 \,\,N_0

we use this to solve for the time (t) in our equation:

0.54\,\,N_0=N_0\,e^{-0.0001\,\,t}\\\frac{0.54\,\,N_0}{N_0}=e^{-0.0001\,\,t}\\0.54=e^{-0.0001\,\,t}\\ln(0.54)=-0.0001\,\,t\\t=\frac{ln(0.54)}{-0.0001} \\t=6161.86\,\,years

which rounded to the nearest year as requested gives :

t = 6162  years
