Answer: 3n ants

Step-by-step explanation:

If there are n ants one month, and the ants triple every month, then next month there will be 3n ants.

We can multiply 3 by n to show it tripling.

To test this, 3(10,000) = 30,000 and 3(270,000) = 810,000, which corresponds to what you've filled out in the table.

Which shows the correct substitution of the values a, b, and c from the equation -2=-x+x^2-4 into the quadratic formula?

Greeley [361]

Given the equation:

(1) $-2=-x+ x^{2}-4$

We need to find a, b and c. So, we know that a quadratic equation is given by:

(2) $ax^{2}+bx+c=0$

Then, we need to order the equation (1) and to adjust it to the equation (2), so:

$x^{2}-x-2=0$

So, if we compare these two equations, the conclusion is:

$a=1$
$b=-1$
$c=-2$

(3) $x= \frac{-b\pm \sqrt{b^{2}-4ac}}{2a}$

Substituiting a, b and c into (3):

$x= \frac{-(-1)\pm \sqrt{(-1)^{2}-4(1)(-2)}}{2(1)}$

Finally, the results are two values:

$x_{1}=2$
$x_{2}=-1$

How much of a 60% acid solution must be mixed with 50 gallons of a 24% acid solution to obtain a solution that is 50% acid?

tiny-mole [99]

My teacher taught me a simple equation for these types of problems:
(percent of solution × amount of solution) + (percent of solution × amount of solution) = (percent of solution × total amount of solution)
in simple terms: %amount + %amount = %total amount
We know don't know how much gallons of 60% solution we need so it will be represented as x. We dont know the total amount either so it would have to be both solutions added together so 50 + x. Now lets solve:
(0.60)(x) + (0.24)(50) = (0.50)(50 + x) simplify/ distribute
0.6x + 12 = 25 +0.5x get all xs on one side and numbers on other
0.1x + 12 = 25
0.1x = 13 divide both sides by 0.1 to find x
x = 130
You need 130 gallons of 60% solution.
