Garth bought 18 boxes, rico bought 36 boxes and mai bought 45 boxes. What is the greatest number of boxes in each pack? How many

GalinKa [24]

If you would like to know what is the greatest number of boxes in each pack, you can calculate this using the following steps:

Garth: 18 boxes / 2 packs = 9 boxes
Rico: 36 boxes / 4 packs = 9 boxes
Mia: 45 boxes / 5 packs = 9 boxes

The correct result would be 9 boxes. Garth bought 2 packs, Rico 4 packs and Mia 5 packs.

The surface area of a cube is 6(a/4)^2, where a is a positive constant. What is the perimeter of one face of the cube?

maksim [4K]

Answer: The perimeter is $a$

Step-by-step explanation:

1. By definition, the formula for calculate the surface area of a cube is:

$SA=6s^{2}$

Where s is the lenght of any edge of the cube.

2. You know that the surface area of the cube of the problem is $6(a/4)^{2}$ , therefore the lenght of each edge of the cube is:

$s=a/4$

3. Each face of the cube is a square, therefore the perimeter of one face is:

$P=4s$

$P=4(a/4)$

$P=4a/4$

$P=a$

11. Find the solutions of x^2-x-30 = 0.

asambeis [7]

To find the solutions of quadratic equation, there are two ways to do which are:

Factorize
Quadratic Formula

<u>S</u><u>t</u><u>e</u><u>p</u><u> </u><u>1</u>

- Factor the expression.

To factor the expression, refer below:

$\displaystyle \large{ (x - a)(x - b) = {x}^{2} - bx - ax + ab}$

For bx and ax, both can be common-factored. Therefore

$\displaystyle \large{ (x - a)(x - b) = {x}^{2} - (b + a)x + ab}$

From the above, we conclude that:

The middle term is b+a
The last term is a×b
Thus, we have to find two numbers that satisfy a+b and a×b

From the expression, 30 comes from 5×6 and when 5-6 = -1. Therefore, a can be 5 and b can be 6.

$\displaystyle \large{{x}^{2} - x - 30 = (x + 5)(x - 6)}$

Because in the middle term, it is -x which is negative, we have to let the highest number become negative.

From the factored expression:

The middle term = 5x + (-6x) = -x
The last term = 5 × (-6) = -30

Then we replace the standard equation with factored form.

$\displaystyle \large{ (x + 5)(x - 6) = 0}$

For this part, we solve like a linear equation where we isolate x. Just think you are solving two linear equations!

Hence

$\displaystyle \large{ x = - 5, 6}$

Therefore, the solutions are x = -5, 6.
