In expanded form, 310409 would be 300000+10000+400+9
Unless you want it as
3*100000+1*10000+4*100+9
Or even
3*10^5+1*10^4+4*10^2+9

What are the coordinates of the center of the ellipse shown below?
photoshop1234 [79]

Answer:

Option D (7, -3)

Step-by-step explanation:

We know that the general equation of an ellipse has the form:

\frac{(x-h)^2}{a^2} + \frac{(y-k)^2}{b^2} = 1

Where the point (h, k) are the coordinates of the center of the ellipse

In this case the equation of the ellipse is:

\frac{(x-7)^2}{4} + \frac{(y+3)^2}{16} = 1

Then

h=7\\\\k = -3

So The coordinates of the center of the ellipse are (7, -3)

HELP ASAPJennifer and Chris completed some chores and split the earnings in the ratio 3:2. Jennifer earned $48.
elixir [45]

Let the total earnings be = x

Jennifer and Chris split the earnings in the ratio 3:2

Jennifer earned = $48

\frac{3x}{5}=48

3x=240

x=80

Hence total earnings are $80

(a) Chris earning is = \frac{2x}{5}=\frac{2*80}{5}=32

Hence, Chris earns $32

(b) Jennifer spends 30% of her earnings on a book.

So, price of the book = \frac{30}{100}\times48

Price of book = $14.40

(c)  Jennifer also buys a magazine for = $5.40

So, total money Jennifer spent on book and magazine = 14.40+5.40=19.80

Money left with Jennifer = 48-19.80= $28.20

In fractions = \frac{28.20}{48}

or multiplying the numerator and denominator by 10, we get

\frac{282}{480}=\frac{47}{80}

(d) Let the original price of the shirt = x

reduction percentage on x= 40%

Price paid after reduction = 16.80

\frac{40x}{100}=16.80

40x=1680

x=42

Hence, the original price of the shirt was $42.
