A person drinks 1 pint of milk a day. At this rate how many gallons will a person drink in a leap year (366 days)?

1 answer:

3 0

OK. SO first you need to know how many pints are in a gallon. ( one gallon = 8 quarts )

One day = one pint. So we want to find what 366 days equals. 1*366=366 pints in 366 days. We now have 366 pints. We need to convert that to gallons. One gallon equals 8 quarts, so we divide 366 by 8. 366/8= 45.75

So in one leap year a person drinks 45.75 gallons of milk

If that doesn't make sense, ask and i can re explain. Hope that helped! <span />

The radius of a right circular cone is increasing at a rate of 1.4 in/s while its height is decreasing at a rate of 2.1 in/s. At

kow [346]

Given:

$\dfrac{dr}{dt}=1.4\text{ in/s}$

$\dfrac{dh}{dt}=-2.1\text{ in/s}$

To find:

The rate of change in volume at $r=120\text{ in. and }175\text{ in.}$

Solution:

We know that, volume of a cone is

$V=\dfrac{1}{3}\pi r^2h$

Differentiate with respect to t.

$\dfrac{dV}{dt}=\dfrac{1}{3}\pi\times \left[(r^2\dfrac{dh}{dt}) + h(2r\dfrac{dr}{dt})\right]$

Substitute the given values.

$\dfrac{dV}{dt}=\dfrac{1}{3}\times \dfrac{22}{7}\times \left[(120)^2(-2.1) +175(2)(120)(1.4)\right]$

$\dfrac{dV}{dt}=\dfrac{22}{21}\times \left[-30240+58800\right]$

$\dfrac{dV}{dt}=\dfrac{22}{21}\times 28560$

$\dfrac{dV}{dt}=29920$

Therefore, the volume of decreased by 29920 cubic inches per second.

If 2/3 = x/y, then which of the following must be true?

Kazeer [188]

Correct option is third $\frac{2+3}{3}=\frac{x+y}{y}$

<h3><u>Solution:</u></h3>

Given that:

$\frac{2}{3}=\frac{x}{y}$

Need to check which of the expression from given four expressions will be true.

Let's first try to eliminate wrong options.

If we observe carefully, we can say that option 2 that is $\frac{3}{2}=\frac{x}{y}$ is not correct as $\frac{x}{y}$ must be equal to $\frac{2}{3}$ and not $\frac{3}{2}$

Lets now modify given expression that is:

$\frac{2}{3}=\frac{x}{y}$

On adding 1 to both sides we get

$\frac{2}{3}+1=\frac{x}{y}+1$

$=>\frac{2+3}{3}=\frac{x+y}{y} \text { which is same as third option. }$

Hence correct option is third one that is $\frac{2+3}{3}=\frac{x+y}{y}$
