Step-by-step explanation:

$18 {v}^{2} - 15v - 18 \\ = 3(6 {v}^{2} - 5v - 6) \\ = 3 \{6 {v}^{2} - 9v + 4v - 6 \} \\ = 3 \{3v(2 {v} - 3) +2( 2v - 3) \} \\ = 3(2v - 3)(3v + 2)$

Two trains are traveling towards each other at a constant speed. The trains are currently 714 miles from each other. The speeds

shutvik [7]

55mph.

you can solve it using the equation distance=speed x time

your total distance is 714, and you have 2 trains, one traveling some speed, x, and one traveling x+8, both traveling for 7 hours.
your equation would look like this
$714 = x(7) + (x+8)(7)$
and you can then solve for x, which would be 47. this is the speed of the slower train, but 47+8=55 with give you the speed of the faster train.

The student council is hosting a drawing to raise money for scholarships. They are selling tickets for $9 each and will sell 500

ryzh [129]

Answer:

-$2.32

Step-by-step explanation:

Give that

The selling price per ticket is $9

And the number of tickets sold is 500

So,

There is one grand prize, three $300 second prize, and eleven $40 third prizes

We need to find out the expected value of the profit

$= \frac{1}{500} \times 2000 + \frac{3}{500} \times 300 + \frac{11}{500} \times 40\\\\$

= 4 + 1.8 + 0.88

= 6.68

Now the expected profit is

= $6.68 - $9

= -$2.32

Jose is thinking of a number.

alexira [117]

The number is 66.

Solution:

Let the number be x.

To find the number x using given conditions.

Start with the last condition.

It is less than 7 times 8 + 23 = 7 × 8 + 23 = 79

So, the number is less than 79 which implies x < 79.

Using condition (4),

It is greater than 5 times 4 = 5 × 4 = 20

So, the number is greater than 79 which implies x > 20.

Combining condition (4) and (7), we get 20 < x < 79.

Using condition (3) and (5),

The number is a multiple of 11 and 6.

The number which is multiplied by both 11 and 6 is 66, 132, ...

But here x lies between 20 < x < 79.

So x = 66.

66 is not odd number and the sum of the digits is divisible by 2.

Therefore condition (1) and (2) also satisfied.

Hence the number is 66.
