Answer:

1.) 20%    2.) 39%    3.) True ; False ; True

Step-by-step explanation:

For the first one, all you need to do is 14 / 70. which is 20%.

For the second one, you need to add 84 and 132. Which is 216. Next just do 84 / 216. Which will then give you 39% (yes I rounded it so don't worry)

And for the third one: True (there are 15 pets in total) ; False (as much as brothers can act like animals they are not lol) ; True (in this case the number of brothers is not necessary)

The region under the curve with equation y = 1/(2x-1) is rotated through four right angles about the x-axis to form a solid. Fin
Vaselesa [24]

Using the disk method, the volume of the solid is

\displaystyle \pi \int_3^8 \left(\dfrac1{2x-1}\right)^2 \, dx = \pi \int_3^8 \frac{dx}{(2x-1)^2}

Substitute u = 2x-1 and du=2\,dx.

\displaystyle \pi \int_3^8 \frac{dx}{(2x-1)^2} = \frac\pi2 \int_5^{15} \frac{du}{u^2} \\\\ ~~~~~~~~ = -\frac\pi2 \frac1u \bigg|_5^{15} \\\\ ~~~~~~~~ = -\frac\pi2 \left(\frac1{15} - \frac15\right) = \boxed{\frac\pi{15}}

Vadim26 [7]

Answer:

0.57 or 0.56

Step-by-step explanation:

passenger fares + tax revenue = operating costs

Thus:

passenger fares = operating costs - tax revenue

= $69 million - $30 million

= $39 million

The ratio of passenger fares to total operating costs is:

$39 million

= 0.5652.

$69 million

To the nearest hundredth, the farebox recovery ratio is 0.57.
