I'm working through this problem, but I'm not getting an answer that is one of the multiple choices.  Maybe there might be a typo, or maybe there is something I don't understand.  But anyway here is my work:

First, we need to find the total hours worked, which if you add the four numbers, the total hours worked is 50.

Second, we know that they put 20% of the $1250 they earned in a savings account.  20% of $1250 is $250.  So they have $1000 left over to split amongst themselves.

One way to continue from this point is to divide the $1000 by the 50 hours to see how much money someone would make per hour.  So, a $1000 divided by 50 hours gives us $20 per hour.

In other words, for every hour that a person contributed to the landscaping business, you would earn $20.

Since Katie contributed 15.25 hours of work, she should get a total of:

15.25 x $20 = $305

Which unfortunately is not one of the answers.  I don't think my calculations are off.  But I hope that helps anyways!

At what value of x does graph of the following function f(x) have a vertical asymptote? F(x)= 1/x+3
kirill115 [55]

Answer:

A

Step-by-step explanation:

Given

f(x) = \frac{1}{x+3}

The denominator of f(x) cannot be zero as this would make f(x) undefined.

Equating the denominator to zero and solving gives the value that x cannot be and if the numerator is non zero for this value then it is a vertical asymptote.

x + 3 = 0 → x = - 3 is the vertical asymptote

a buret is a tool designed to transfer precise amounts of liquid .A buret initially contains 70.00 millimeters of a solution and
katrin [286]

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}
