14 out of 20 students pack their lunches. what percent of students pack their lunches?

1 answer:

7 0

Think of it as a fraction (14/20). If you multiply 20 by 5, you get 100. Whatever you do to the bottom, you have to do to the top. So 14 x 5 would be 70. The entire fraction would be 70/100 or 70%.

Write an exponential equation in the form y = ab* whose graph passes through points (2, 18) and (5, 60.75).

DochEvi [55]

Let $y=ab^x,$ as described in the problem statement. Plugging in $x=2$ and $x=5$ gives us the equations $18=ab^2$ and $60.75=ab^5.$ Since $a,b$ are nonzero, we divide the second equation by the first to get $\frac{27}{8}=b^3,$ which means that $b=\frac{3}{2},$ after taking the cube root. Plugging this value for $b$ into the first equation, we now have $18=a(3/2)^2=\frac{9a}{4}.$ Solving gives $a=8,$ and our desired exponential equation is $\boxed{y=8\left(\frac{3}{2}\right)^x}.$
