A vat with 700 gallons of beer contains 4% alcohol (by volume). Beer with 6% alcohol is pumped into the vat at a rate of 7 gal/m
dolphi86 [110]

Answer:

5.2%.

Step-by-step explanation:

After 1 hour (60 / 100) * 700 = 420 gallons of beer have been exchanged.

So we have 420 gallons of 6%  and 280 gallons of 4% after 1 hour.

So the strength at that time =  (420* 6) + 280*4) / 700

= 5.2%.

the measure of angle is 7π/6. the measure of its reference angle is *blank* degrees, and sin is *blank*.
marin [14]
The measure of angle θ = 7pi/6. To convert this to degrees, substitute pi with 180 degrees. Pi is always equal to 180 degrees.
θ becomes: 7 x 180/6
Therefore, θ = 210 degrees.
And, to solve for sin θ, you can directly input sin (210) in the calculator. 
Thus, sin θ = sin (210) = -0.5 or -1/2

Find the distance between two points: (5,3),(8,5)​
kozerog [31]

Answer:

\displaystyle\boxed{\rm \: Distance= \underline{\underline{\sqrt{13}}}}

<em>OR </em><em>in </em><em>Decimal</em>,

\boxed{\rm \: Distance=\underline{\underline{3.605}}}

Step-by-step explanation:

<u>Given:</u>

Two points, that is (5,3) & (8,5)

<u>To Find:</u>

The Distance of the two given points

<u>Solution:</u>

To Find the distance between two points, we will use the <u>distance</u> <u>formula</u>, i.e. :

\boxed{ \rm \: Distance =  \sqrt{(x_2 - x_1) {}^{2}  + (y_2 - y_1) {}^{2} } }

According to the Question,

\rightarrow \:  \rm \: x_2 = 8

\rightarrow \:  \rm \: x_1 = 5

\rightarrow \:  \rm \: y_2 = 5

\rightarrow \:  \rm \: y_1 = 3

Now Substitute the values on the formula of Distance and then Simplify:

\rm \: Distance= \sqrt{(8 - 5 )^{2}  + (5 - 3) {}^{2} }

<em>[Follow PEMDAS rule while simplifying]</em>

\rm \: Distance= \sqrt{3 {}^{2}  + 2 {}^{2} }

\rm \: Distance= \sqrt{(3 \times 3) + (2 \times 2)}

\rm \:  Distance= \sqrt{9 + 4}

\rm \: Distance= \sqrt{13}

\rm \: Distance= {3.605}

Hence, the distance between the two given points would be \sqrt{13} or 3.605.

\rule{225pt}{2pt}

I hope this helps!

Have a good day! :)
