$56.25

8:25 - 4:25 = 4 hours

4 hours - 1 hour for lunch = 3 hours

$18.75 x 3 = $56.25

A bell rings every 1/6 hour. assuming it just rang,how many times will it ring in the next 2/3 hour?
Paraphin [41]

1 hr = 60 min

1/6 hr = (60/6) min = 10 min

so the bell rings every 10 min. Since 1 hr = 60 min, this means that 2/3 of that is 40 min. So the bell will ring 4 times (divide 40 over 4) in the next 2/3 of an hour, which is the same as saying "the bell will ring 4 times in the next 40 minutes"

Answer: 4 times

Find the volume of the solid of revolution formed by rotating about the x--axis the region bounded by the given curves.
amm1812

Answer:

V = \frac{8\pi}{3}

Step-by-step explanation:

For this case we are interested on the region shaded on the figure attached.

And we can find the volume with the method of rings.

The area on this case is given by:

A(x) = \pi [f(x)]^2 = \pi r^2 = \pi [3x]^2 = 9\pi x^2

And the volume is given by the following formula:

V= \int_{a}^b A(x) dx

For our case our limits are x=0 and x=2 so we have this:

V = \pi \int_{0}^{2} x^2 dx

And if we solve the integral we got this:

V= \pi [\frac{x^3}{3}]\Big|_0^{2}

And after evaluate we got this:

V=\pi [(\frac{8}{3} )-(\frac{0}{3} )]

V = \frac{8\pi}{3}
