If the area of a rectangular garden is 45x2−12x square meters, and it has a length of 3x meters, what is its width?

nikitadnepr [17]

Answer:

(9x -4) meters

Step-by-step explanation:

The relationship between area, length, and width is ...

area = length × width

Dividing by length gives ...

width = area/length

Filling in the given expressions, we have ...

$w=\dfrac{45x^2-12x}{3x}=\dfrac{45x^2}{3x}-\dfrac{12x}{3x}=9x-4$

The width of the garden is 9x-4 meters.

A report states that 32% of New Jersey residents think that a nice car costs too much money. Which element should probably be be

SOVA2 [1]

You should probably define what makes a car "nice", and also quantify the "too much money".

Qualitative words are often not welcomed in maths/science in general, because people can disagree on their meaning.

So, for example, if you change the sentence into

"A report states that 32% of New Jersey residents think that mercedes cars cost 30% more than they should"

Then everything would be "fixed", and there is no ambiguity anymore

Eli attended a concert. The decibel level of the music averaged 110 decibels but varied by 28 decibels from the average. Enter a

musickatia [10]

Answer:

The decibel range is $82\leq d\leq 138$

Step-by-step explanation:

Let

d -----> the decibel level of the music

we know that

The absolute value of the difference of the decibel level of the music and its average, must be less than or equal to 28 decibels

The absolute value that represent this problem is

$\left|d-110\right|\le28$

Solve the absolute value

<em>First solution (positive)</em>

$+(d-110)\le28$

Adds 110 both sides

$d\le28+110$

$d\le138$

<em>Second solution (negative)</em>

$-(d-110)\le28$

Multiply by -1 both sides

$(d-110)\ge-28$

Adds 110 both sides

$d\ge-28+110$

$d\ge82$

therefore

The decibel range is

$82\leq d\leq 138$
