Let:

Vbu= Volume of the buret

Vbk= Volume of the beaker

A buret initially contains 70.00 millimeters of a solution and a beaker initially contains 20.00 ml of the solution the buret drips solution into the Beaker. each drip contains 0.05 mL of solution, therefore:

x = Number of drips

a = volume of each drip

\begin{gathered} Vbu=70-ax \\ Vbk=20+ax \\ \text{where:} \\ a=0.05 \\ Vbu=70-0.05x \\ Vbk=20+0.05x \end{gathered}

after how many drips will the volume of the solution in the buret and beaker be equal ?​ Vbu = Vbk:

\begin{gathered} Vbu=Vbk \\ 70-0.05x=20+0.05x \\ \text{Solve for x:} \\ 0.1x=70-20 \\ 0.1x=50 \\ x=\frac{50}{0.1} \\ x=500 \end{gathered}

If the diameter of a circle is 25 inches, what is the radius of the circle?
sergij07 [2.7K]
Hello there, and thank you for posting your question here on brainly.

The diameter of a circle is how long it is from the left side of the circle to the right side.

The radius of a circle is the length of either the left or the right side to the middle.

So, the radius is half of a radius.

You can divide the known diameter by 2 to get your answer.

Its diameter is 25.

Divide 25 by 2.

25 / 2 = 12.5

Its radius is 12.5 in.

That would be answer choice A.

Hope this helped!! ☺♥
