An IV infiltrates with 330 mL remaining in the bag. It was restarted at 1015 at a rate of 30 mL/hr. What is the IV completion ti
DochEvi [55]

Answer:

11 hours

Step-by-step explanation:

I came up with this answer by dividing the IV infiltrate in the bag by the rate. This gave the completion time.

Volume of IV infiltrate = 330ML

Rate at which it was running = 30 ML/hour

The IV completion time = volume/rate

= 330 ML/30 ML

= 11 hours

Therefore the IV completion time is 11 hours.

Manuel bought a balloon (that is a perfect sphere) with a radius of 2 \text{ cm}2 cm2, start text, space, c, m, end text. He wan
mote1985 [20]

Answer:

<h2>The required ratio is 8</h2>

Step-by-step explanation:

Volume of a sphere = \frac{4}{3}\pi  r^{3} where r is the radius of the sphere.

If manuel bought a balloon (that is a perfect sphere) with a radius of 2cm, the original volume of the sphere is expressed as;

Vo = \frac{4}{3}\pi  (2)^{3}

Vo  = \frac{4}{3}\pi *8\\Vo = \frac{32 \pi}{3}

If he wanted his balloon to be bigger and he blew 2 big breaths of air into the balloon, if each big breath increased the balloon's radius by 1cm, the total radius will be the initial radius of the sphere plus the new radius after expansion.

radius of current sphere = 2cm+(1cm+1cm) = 4cm

Volume of the current sphere Vc = \frac{4}{3}\pi  (4)^{3}

Vc = \frac{4}{3}\pi *64\\Vc = \frac{256 \pi}{3} \\

The ratio of the current volume of the balloon Vc to the original volume of the balloon Vo will be expressed as;

Vc/Vo = \frac{\frac{256\pi}{3} }{\frac{32\pi}{3} }

\frac{Vc}{Vo}=\frac{256\pi}{3}*\frac{3}{32\pi}   \\\frac{Vc}{Vo}=\frac{256}{32}\\\frac{Vc}{Vo}= 8

The required ratio is 8
