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 $\mathrm{Decimal}:\quad t=496.89261\dots$

algol13

Well, if he uses 3/8 cup per loaf and makes 6 loaves then basically all you will need to do is 3/8 times 6 which =s 24/8. And how many times does 8 go into 24? 3 times, so Carlos will use 3 cups of brown sugar for his banana bread loaves.

Hope this helps!:);)

Can someone answer this for my homework

kenny6666 [7]

we are given

The angle is at right angled

It means that it's angle will be 90 degree

Since, these angles are part of right angle

so, their sum must be 90 degree

so, we get

$4a+5+3a-6=90$

now, we can solve for a

$4a+3a-1=90$

$7a=91$

divide both sides by 7

and we get

$a=13$ .............Answer
