$256 / 100 = 2.56
2.56 x 23 = 58.88

$256 - $58.88 = $197.12

The sale price is $197.12
The decrease in price is $58.88

Hope it helped :)

Answer:

Decrease in price is $ 58.88 and sales price is $ 197.12

Step-by-step explanation:

Given,

The orginal price of the coat = $ 256,

Percentage of discount = 23%,

Thus, the decrease in price = 23% of the original price

= 23% of 256

=\frac{23\times 256}{100}

=\frac{5888}{100}

= $ 58.88

Also, the sales price of the coat = original cost - decrease in price

= 256 - 58.88

= $ 197.12

Micah is watching a TV program that is 2 hours long during the program there are six commercials that are each 90 sec. How many
Sergeu [11.5K]

Answer:

111 minutes

Step-by-step explanation:

step 1

Find out how long are the six commercial

Multiply the number of commercials by 90 seconds

so

90(6)=540\ sec

Convert to minutes

Remember that

1\ min=60\ sec

540\ sec=540/60=9\ min

step 2

Subtract the duration of six commercials from the duration of the program

Remember that

1\ h=60\ min

so

2\ h=2(60)=120\ min

therefore

120-9=111\ min

At what value of x does the graph of the function f(x) have a vertical asymptote?
choli [55]
It will have a vertical asymptote when the denominator approaches zero.

2x-6=0

2x=6

x=3

So the vertical asymptote is the vertical line x=3

First mug holds the most

<em><u>Solution:</u></em>

Given that,

You are choosing between two mugs

<em><u>The volume of cylinder is given as:</u></em>

V = \pi r^2h

Where,

r is the radius and h is the height

<em><u>One has a base that is 5.5 inches in diameter and a height of 3 inches</u></em>

radius = \frac{diameter}{2}

Therefore,

r = \frac{5.5}{2}\\\\r = 2.75

Also, h = 3 inches

<em><u>Thus volume of cylinder is given as:</u></em>

V = \pi \times 2.75^2 \times 3\\\\V = 3.14 \times 22.6875\\\\V = 71.23875 \approx 71.24

Thus first mug holds 71.24 cubic inches

<em><u>The other has a base of 4.5 inches in diameter and a height of 4 inches</u></em>

Radius = \frac{4.5}{2}\\\\r = 2.25

h = 4 inches

Therefore,

V = 3.14 \times 2.25^2 \times 4\\\\V = 3.14 \times 20.25\\\\V = 63.585

Thus the second mug holds 63.585 cubic inches

On comparing, volume of both mugs,

Volume of first mug > volume of second mug

First mug holds the most

Solve for x<br> Urgent need help
fiasKO [112]
I believe you need to solve this using the quadratic formula!
To begin, this is what it is:
x= -b ± <span>√ b^2 - 4ac / 2a
Just plug in what you have in your problem...
2 being a, 13 being b, and -24 being c.
So we get:
x= -13 </span>± <span>√13^2 - 4(2)(-24) / 2(2)
x= -13 </span><span>± √169 - 8 (-24) / 4</span>
<span>x= -13 <span>± √169 + 192 / 4</span>
x= -13 </span>± √<span>361 / 4
The square root of 361 is 19.
So you have: -13 </span><span>± 19 / 4.
Here's where you take the equation </span>-13 <span>± 19 and put the addition and subtraction sign to use.
-13 - 19 = -32
and
-13 + 19 = 6
Now all is left to do is divide the two numbers by 4.
-32/4 = -8
and
6/4 = 3/2

x = -8, 3/2</span>
