Tyrese wants to buy baseball cards. They cost $5.00 per pack. There is a 25% discount before tax if 10 or more packs are purchas

irga5000 [103]

Answer:

72.225 $

Step-by-step explanation:

The price per pack: 5.00 $

When the amount of packs is > 10 :

90 % * 5 $ = 4.50 $ before tax.

The price of 15 packs:

4.50 $ * 15 = 45 + 22.5 = 67.5 $ before tax.

After tax:

107 % * 67.5 $ = 72.225 $ after tax.

A 75% increase followed by a 33 1/2% decrease

o-na [289]

After 75% increase followed by a 33 1/2% decrease the net increased is 16.375%.

<u>Solution:</u>

Need to determine net percentage increase or decrease when a value is increased by 75% and then decreased by $33 \frac{1}{2} \%$ that is 33.5%.

Let’s assume initial value be represented by variable x.

$75 \% \text { decrease means } x+75 \% \text { of } x=x+\frac{75}{100} x=x+0.75 x=1.75 x$

Now there is decrease of 33.5%

$\begin{array}{l}{33.5 \% \text { decrease means } 1.75 x-33.5 \% \text { of } 1.75 x=1.75 x-\frac{33.5}{100} \times 1.75 x} \\\\ {=1.75 x-(0.335 \times 1.75) x=1.75 x-0.58625 x} \\\\ {=1.16375 x}\end{array}$

$\text { So increase in percentage }=\frac{\text { final value-initial value}}{\text { intial value }}$

$=\frac{1.16375 x-x}{x} \times 100=16.375 \%$

Hence after 75% increase followed by a $33 \frac{1}{2} \%$ decrease the net increased is 16.375%.

I’ll give brainliest

faust18 [17]

Step-by-step explanation:

Let

c = 11.5 cm

a = 8.9 cm

b = ?

Since this is a right triangle, we can use Pythagorean theorem to find the length of side b:

$c^2 = a^2 + b^2$

$\Rightarrow b^2 = c^2 - a^2$

Taking the square root of the equation above, we get

$b = \sqrt{c^2 - a^2} = \sqrt{(11.5\:\text{cm})^2 - (8.9\:\text{cm})^2}$

$\:\:\:\:=7.3\:\text{cm}$

Find an equation of the circle that satisfies the stated conditions. (Give your answer in standard notation.)

BartSMP [9]

Answer:

The equation of a circle will be:

(x+6)² + (y - 2)² = 25

Step-by-step explanation:

We have to find the equation of the circle that satisfies the stated conditions.

Center C(−6, 2)

Tangent to the y-axis

We know that the equation of a circle is

(x - h)² + (y - k)² = r²

here:

(h, k) is the center point

r is the radius

Given that the circle is tangent to the y-axis, we just need to determine the distance between x = 0 and x = -6.

As the distance between x = 0 and x = -6 is 6. Thus, 6 will be the radius of the circle.

In other words,

radius r = 6

Therefore, the equation of a circle is:

(x - h)² + (y - k)² = r²

(x - (-6))² + (y - 2)² = (5)²

(x+6)² + (y - 2)² = 25

Thus, the equation of a circle will be:

(x+6)² + (y - 2)² = 25
