Step-by-step explanation:

The area would be 21

Feet would be = 50.4 (21 x 2.4)

Then it would cost $176.40 (50.4 x $3.50)

I might be wrong, I'm not entirely sure.

A grocer bought n eggs at $x each. He marked up the price of each egg by $y and sold all of them. Find the sales amount, express
Alex777 [14]

Answer:

Sales = n \times ($x + $y)

Step-by-step explanation:

The basic simple sales equation is

Quantity \times Price = Sales

Here in the given question,

Total quantity of sales = n

Price = Cost + markup

(Markup refers to the profit added to cost)

Thus price = $x (cost) + $y (markup)

Sales = n \times ($x + $y)

Sales amount is the total amount received from sales of products, total quantity at some price provided.

Vertex form is f(x)=a(x-p)^2 +q. How do i determine a?
slamgirl [31]
Y1 is the simplest parabola.  Its vertex is at (0,0) and it passes thru (2,4).  This is enough info to conclude that y1 = x^2.

y4, the lower red graph, is a bit more of a challenge.  We can easily identify its vertex, which is (-4,0), and several points on the grah, such as (2,-3).

Let's try this:  assume that the general equation for a parabola is 
y-k = a(x-h)^2, where (h,k) is the vertex.  Subst. the known values,

-3-(-4) = a(2-0)^2.  Then 1 = a(2)^2, or 1 = 4a, or a = 1/4.

The equation of parabola y4 is   y+4 = (1/4)x^2

Or you could elim. the fraction and write the eqn as 4y+16=x^2, or

4y = x^2-16, or    y = (1/4)x - 4.  Take your pick!  Hope this helps you find "a" for the other parabolas.

A sample with mean of 85 and SD of 12 is transformed into z-scores. After the transformation, what are the values for the mean a
MrRa [10]

Answer:

The value remain unchanged.

Step-by-step explanation:

By Z score, we mean:

Z = \frac{x-\mu}{\sigma}, if we substitute the given values of mean and standard deviation, we obtain the z score value. That is,

Z =  \frac{85 - 0}{12} = 85/12 = 7.083333.

NB: We assume that mean and standard deviation are in the same units.

In the late nineteenth century, the scientist Marie Curie performed experiments that led to the discovery of radioactive substan
gtnhenbr [62]

Answer:

Step-by-step explanation:

Half life is the time taken by a radioactive substance to reduce of half of its original size

If the half life of radium is 1600, this means that the original radioactive substance N0 have reduced to N0/2 after 1600 years

if we are given N0 = 1000grams

The amount of the substance that will remain after 1600 years will be N0/2 i.e 1000/2 = 500g

<em>Hence 500 grams of radium will be left after 600years</em>
