Answer:

Tax credits directly reduce the amount of tax you owe, giving you a dollar-for-dollar reduction of your tax liability. ... Deductions lower your taxable income by the percentage of your highest federal income tax bracket. So if you fall into the 22% tax bracket, a $1,000 deduction saves you $220

The pressure exerted on the walls of a container by a gas enclosed within it is directly proportional to the temperature of the
Inessa [10]

Answer:

Step-by-step explanation:

If y is directly proportional to x, then the formula for that is a linear one:

y = kx, where k is the constant of proportionality.  In our situation, if the pressure is directly proportional to the temp, then our formula is

P = kT.  We need to find that value of k.  Plug in what we have:

6 = k(440) so

k = .01363636 or as an equivalent fraction,

k=\frac{3}{220}

Now that have that value of k, we can use it in the formula again, this time with a different value for T to solve for P.

P=(\frac{3}{220})380 so

P = 5.181818 or as an equivalent fraction,

P=\frac{513}{100}

Hello, could anyone please help me with my homework?
IRINA_888 [86]

Answer: See below

Step-by-step explanation:

100\left(\frac{1}{2}\right)^{\frac{t}{214}}=20

\mathrm{Divide\:both\:sides\:by\:}100

\frac{100\left(\frac{1}{2}\right)^{\frac{t}{214}}}{100}=\frac{20}{100}

Simplify

\left(\frac{1}{2}\right)^{\frac{t}{214}}=\frac{1}{5}

\mathrm{If\:}f\left(x\right)=g\left(x\right)\mathrm{,\:then\:}\ln \left(f\left(x\right)\right)=\ln \left(g\left(x\right)\right)

\ln \left(\left(\frac{1}{2}\right)^{\frac{t}{214}}\right)=\ln \left(\frac{1}{5}\right)

\mathrm{Apply\:log\:rule\:}\log _a\left(x^b\right)=b\cdot \log _a\left(x\right)

\ln \left(\left(\frac{1}{2}\right)^{\frac{t}{214}}\right)=\frac{t}{214}\ln \left(\frac{1}{2}\right)

\frac{t}{214}\ln \left(\frac{1}{2}\right)=\ln \left(\frac{1}{5}\right)

\frac{\ln \left(\frac{1}{2}\right)t}{214}=\ln \left(\frac{1}{5}\right)

\mathrm{Multiply\:both\:sides\:by\:}214

\frac{214\ln \left(\frac{1}{2}\right)t}{214}=214\ln \left(\frac{1}{5}\right)

-\ln \left(2\right)t=-214\ln \left(5\right)

\mathrm{Divide\:both\:sides\:by\:}-\ln \left(2\right)

\frac{-\ln \left(2\right)t}{-\ln \left(2\right)}=\frac{-214\ln \left(5\right)}{-\ln \left(2\right)}

t=\frac{214\ln \left(5\right)}{\ln \left(2\right)} or \mathrm{Decimal}:\quad t=496.89261\dots
