Answer:

$972

Step-by-step explanation:

Ajax buys 20 shares of stock at $20.

The cost of 20 shares = 20 × $20 = $400

The shares increase in value by 20%

Now the cost of 20 shares = 400 + (20%×400)

                                            = 400 + 80

                                            = $480

Cost per share =   = $24

He sells 10 shares = $20 × 10 = $240

Now he has 10 share costs $240

After the shares decrease in value by 10%, he buys another 20 shares.

Cost per shares after decrease by 10% = 24 - (10%×24)

                                                                 = 24 - 2.40

                                                                 = $21.60

He buys 20 shares and his remaining 10 shares = 20 + 10 = 30 shares

Cost of 30 shares = 21.60 × 30 = $648

The shares then all increase by 50% = 648 + (50% × 648)

                                                             = 648 + (0.5 × 648)

                                                             = 648 + 324

                                                             = $972

The total value of the 30 shares that Ajax own is $972

Yes because 0 to 9 has 10 is 0,1,2,3,4,5,6,7,8,9 so 10

We have that \(8=x^2+y^2=x^2+2xy+y^2-2xy=(x+y)^2-2xy=16-2xy\), therefore .\(xy=\frac{16-8}{2}=4\) Since \(x^3+y^3=(x+y)(x^2-xy+y^2)=(x+y)(x^2+y^2-xy)\), we can directly substitute in the numerical values for each algebraic expression. This gives us \(x^3+y^3=(4)(8-4)=\boxed{16}\).

\(-0.3x+3=4.2\)

\(-0.3x=1.2 \)

\(x=-0.4 \)

The number of digits on each dial is 10 and they are independent of each

other (mutually exclusive) so the number of different combinations is ....

==> 10 x 10 x 10 x 10 = 10,000

So, the probability of guessing the combination is 1 / 10,000 = 0.0001

Summing all three equations together, every term on the left-hand side cancels out, yielding that \(0 = a + 15 - 7 \Longrightarrow a = \boxed{-8}\).

I forgot about that dang

If the second side has length x,

Then the first side has length 3x,

We know that the third side which has length 17.

Now, by the triangle inequality, we have:

x + 17 > 3x

=> 2x < 17

=> x < 8.5

Since we want the greatest perimeter,so we need the greatest integer x, and if x < 8.5.

Then x = 8

Then, the first side has length -> 3 x 8 = 24

The second side has length = 8 cm

The third side has length = 17 cm

So,perimeter = 17 + 24 + 8 = 49 cm

Cross-multiplication gives 

\(x^2+2x+3=(x+4)(x+5)=x^2+9x+20. \)

Therefore

\(0=7x+17\)

and \(x=\boxed{-\frac{17}7}\).
