Hunter and Brian are creating a poster for a project and they need to combine two different size boards to create their project.

shepuryov [24]

Answer:

<em>The maximum area of the second board must be $(5x^2+3x-6)$ square inches.</em>

Step-by-step explanation:

The total area of two different size boards cannot exceed $(7x^2-6x+2)$ square inches.

The area of one board is $(2x^2-9x+8)$ square inches.

Suppose, the area of the second board is $y$ square inches.

That means......

$y+(2x^2-9x+8)\leq 7x^2-6x+2\\ \\ y\leq (7x^2-6x+2)-(2x^2-9x+8)\\ \\y \leq 7x^2-6x+2-2x^2+9x-8\\ \\ y\leq 5x^2+3x-6$

So, the maximum area of the second board must be $(5x^2+3x-6)$ square inches.

Ally collects stickers as a hobby. She gives her sisters of her stickers.

sertanlavr [38]

Answer:

$\frac{16}{25}$

Step-by-step explanation:

Ally gives her sister = 1/5 stickers

Ally gives her cousin = 1/5 of the remainder stickers

Assume Number of sticker Ali has = 1

Remainder after giving stickers to her sister = 1 - 1/5 = 4/5

Number of stickers she gave her sister = $\frac{1}{5}\times\frac{4}{5}$

= $\frac{4}{25}$

Sticker she has = $1-\frac{1}{5}-\frac{4}{25}$

= $\frac{25-5-4}{25}$

= $\frac{16}{25}$

Sticker left with Ally is equal to $\frac{16}{25}$ .

What number is halfway between -15 and 20

ollegr [7]

Answer : 2.5

Solution:

To find the halfway number it means that you need to find the middle most value using the formula

Mid value = (X + Y) / 2

So in this case it would be,

Mid value = (-15 + 20 ) / 2

Mid Value = ( 5 ) / 2

Mid Value = 2.5 answer

Hope this helps in understanding the question! :)

Note : do not forget the negative sign as it will change the answer and may cost you marks!
