Karolina [17]3 years ago

6 0

Answer:

6^-13

Step-by-step explanation:

The rule for multiplying numbers with the same base but different exponents is a^b*a^c=a^(b+c), so in this case we have 6^(-4+(-9)) which is 6^-13

Hope this helped!

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:

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

Use the rules of exponents to evaluate or simplify. Write without negative exponents.<br> (-243)^3/5

IRINA_888 [86]

Answer:

-27

Step-by-step explanation:

(-243)^3/5

We know that a^b^c = a^ (b*c)

(-243) ^ 1/5 ^3

We know (-243) ^ 1/5 = -3

(-3) ^3 = -27

WILL MARK BRAINEST PLZ HELP! What is the value of x? (With all of the details on how to get it.

klasskru [66]

To find x:

Subtract 10 on both sides.

10 + 2x = 90

-10 -10

Divide 2 on both sides.

2x = 80

--- ---

2 2

This would get x alone.

x = 40

Check:

10 + 2(40) = 90

10 + 80 = 90

90 = 90

The value of x is 40. The angle degree of it is 80 when you multiply 2 by 40.
