At a grocery store, you can buy a 20-ounce of peanuts for $3.59, or you can buy a one-pound (16 ounces) package for $2.59. Why i

uranmaximum [27]

Answer- The one pound package is a better deal because it costs 32 cents per ounce rather than the 20 oz, which charged 45 cents per oz.

Explanation- let’s convert all units to ONE OUNCE. 3.59/20(oz)= 0.45, do 45 cents per ounce for the first. For the second, we know that one pound is 8 oz so divide 2.59 by 8 and you get 32 cents per oz. We know that if we are getting 8 oz for 32 cents per ounce, it is the better deal rather than 45 cents per oz.

Answer:

Step-by-step explanation:

The circle is divided into 5 sections. The probability that the needle lands on a particular color is equally likely.

So,

$P(red) = \frac{1}{5}\\\\P(green) = \frac{1}{5}\\\\$

Probability of not blue = 1 - Probability of blue

$= 1 - P(blue)\\\\=1 - \frac{1}{5}\\\\= \frac{4}{5}$

The area of a rectangular parking lot is represented by A = 6x^2 − 19x − 7 If x represents 15 m, what are the length and width o

Mekhanik [1.2K]

Answer:

The length and width of the parking lot are $\frac{46}{3}$ meters and $\frac{23}{2}$ meters, respectively.

Step-by-step explanation:

The surface formula ( $A$ ) for the rectangular parking lot is represented by:

$A = w\cdot l$

Where:

$w$ - Width of the rectangle, measured in meters.

$l$ - Length of the rectangle, measured in meters.

Since, surface formula is a second-order polynomial, in which each binomial is associated with width and length. If $A = 6\cdot x^{2}-19\cdot x -7$ , the factorized form is:

$A = \left(x-\frac{7}{2}\,m \right)\cdot \left(x+\frac{1}{3}\,m \right)$

Now, let consider that $w = \left(x-\frac{7}{2}\,m \right)$ and $l = \left(x+\frac{1}{3}\,m \right)$ , if $x = 15\,m$ , the length and width of the parking lot are, respectively:

$w =\left(15\,m-\frac{7}{2}\,m \right)$

$w = \frac{23}{2}\,m$

$l =\left(15\,m+\frac{1}{3}\,m \right)$

$l = \frac{46}{3}\,m$

The length and width of the parking lot are $\frac{46}{3}$ meters and $\frac{23}{2}$ meters, respectively.
