$\left(\dfrac{3a^{-3}b^2}{2a^{-1}b^0}\right)^2$

First some simplifying:

$\left(\dfrac{3a^1b^2}{2a^3b^0}\right)^2=\left(\dfrac{3b^2}{2a^2}\right)^2=\dfrac{9b^4}{4a^4}$

Then with $a=-2$ and $b=-3$ , we have $a^4=(-2)^4=16=4^2$ and $b^4=(-3)^4=81=9^2$ , so

$\dfrac{9b^4}{4a^4}=\dfrac{9\cdot9^2}{4\cdot4^2}=\dfrac{9^3}{4^3}=\dfrac{729}{64}$

The density of silver is 10.5 g/cm. Find the volume of a silver bar if it’s mass is 950 g.

denis-greek [22]

Answer: The volume is 90.47 $cm^{3}$

Step-by-step explanation:

1. To solve this problem you need to use the formula for calculate the density, which is shown below:

$d=\frac{m}{V}$

Where $m$ is the mass and $V$ is the volume.

2. You must solve for the volume, as following:

$V=\frac{m}{d}$

3. Now, you must substitute the values of the mas and the density, which are given in the problem. Therefore, you have:

$V=\frac{950g}{0.5g/cm^{3}}\\V=90.47cm^{3}$

Tickets for a train cost $22 for adults and $10 for children. Josie paid $1,200 for a total of 72 tickets. How many adult ticket

ehidna [41]

Answer:

Josie bought 40 adult tickets and 32 children tickets.

Step-by-step explanation:

x+y=72

22x+10y=1200

-----------------------

x=72-y

22(72-y)+10y=1200

1584-22y+10y=1200

1584-12y=1200

12y=1584-1200

12y=384

y=384/12=32

x+32=72

x=72-32=40

x=40, y=32. (40, 32)
