Answer:

\frac{23}{5}

Step-by-step explanation:

x + ( -  \frac{13}{5} ) = 2 \\ x -  \frac{13}{5}  = 2 \\ x = 2 +  \frac{13}{5}  \\ x =  \frac{10 + 13}{5}  \\ x =  \frac{23}{5}

<em><u>Problem One</u></em>

Remark

You don't pay a sales tax until cash is exchanged for goods or services.

So what is 70% off

Solution

Sale price = given price * (100% - 70%)

Sale Price = 72 * 30%

Sale Price = 72 * 30/100

Sale Price = 72 * 0.3

Sale Price = 21.6 dollars.

The sales tax is 5% of this amount

21.6 * 5/100 = 1.08

The total cost is = 21.6 + 1.08 = 22.68

Problem Two

If they marked up 100%, effectively they doubled the price.

New Price = old price + 100% of old price.

New Price = 48.50 + 48.50 = 97 dollars.

The sales tax is 6% * 97 = 6/100 * 97 = 5.82

Total Cost = Cost of item + Tax

Total Cost =97 + 5.82

Total Cost = 102.82 Answer <<<<

Explain how to rewrite the given equation in vertex form: y = x^2 – 6x + 4
lora16 [44]
Multiply out the "a times the squared coefficient" part on the left-hand side (remember, in this one a = 1 so that does nothing), and convert the right-hand side to squared form. (This is where you use that sign you kept track of earlier, putting that sign in the middle of the squared expression.)

y-4+(9)=(x+3)^2

Simplify - combine like terms.

y+5=(x+3)^2

Move the constant term from the right back to the left.

y=(x+3)^2 - 5

Write in vertex form y=(a(x-h)^2) + k. In other words, if the squared term is x+h write it as x-(-h). If the k term is negative, write it as + (-k).

y=(x-(-3))^2 + (-5)

Now the values for h and k are clear.I hope that this is the answer that you were looking for and it has helped you.

The value of a bike depreciates by 35% per year. Work out the current value of a bike bought 2 years ago for £600.
barxatty [35]
First you would find how much 35 percent of 600 is using 600/100 to find the value of one percent. One percent equals 6 pounds.

The volume of this cone is 602.88 cubic inches. What is the radius of this cone?
choli [55]

Answer:

8

Step-by-step explanation:

Volume of a cone formula: V = \pi r^{2} \frac{h}{3}

where,

h is the height             <u>9 in  (assuming)</u>

r is the radius              <u>want</u>

v is the volume           <u> 602.88 cubic inches</u>

\pi is                              <u>a = 3.14 </u>

Plug in everything:

602.88 = 3.14r^{2} (\frac{9}{3} )\\602.88 = 3.14r^{2} (3)\\1808.64 = 28.26r^{2}\\\frac{1808.64}{28.26} = \frac{28.26r^{2}}{28.26} \\r^{2} = 64\\r = \sqrt{64} \\r = 8\\or\\r =-8
