Answer:

$ 22.98

Step-by-step explanation:

discounted = 5%

sold at = 100 % - 5%

= 95%

let the original price of CD be x

= 95% of x =21.84

= 95/100 × x = 21.84

= x = 21.84 × 100/95

= x = 2184/95

Answer:

7 Months and 15 Days

Step-by-step explanation:

The months that you chose had all 31 days, besides april. So you add them all up and just add the remainder into your answer.

Step-by-step explanation:

well,

(y - 7)² = (y - 7)(y - 7)

remember how to multiply 2 expressions ?

you have to multiply every term of one expression with every term of the other expression and sum the results all up (incl. considering their individual signs, of course).

so, when we do the multiplication, we get

(y - 7)(y - 7) = y×y - 7×y - 7×y + (-7)×(-7) =

= y² - 14y + 49

and that is clearly different to y² - 49

FYI

y² - 49 is the result of

(y - 7)(y + 7)

because

y×y + 7×y - 7×y + (-7)(7) = y² - 49

Answer:

The exponent of an expression says how many times to multiply the expression.

[tex]\implies (y-7)^2=(y-7)(y-7)[/tex]

Expand the brackets:

[tex]=y^2-7y-7y+49[/tex]

Combine like terms:

Answer:

  see the attachments for the graph, and a spreadsheet with midpoints and slopes

Step-by-step explanation:

We are given the coordinates of the vertices of a triangle, and asked to find the parameters of the perpendicular bisectors of the sides of the triangle. The perpendicular bisectors are to be plotted on the graph.

Coordinates A(1, 6), B(5, 4), C(5, -2)

__

a) Graph and label the triangle

b) Find the midpoint of each side of the triangle

c) Find the slope of each side of the triangle

d) Find the slope of each perpendicular bisector

e) Use the midpoint and the perpendicular slope to accurately draw each perpendicular bisector on the triangle

__

See the attached graph for shaded triangle ABC.

__

The midpoint (M) of a segment AB will be ...

  M = (A+B)/2

For example, the midpoint of segment AB is ...

  D = ((1, 6) +(5, 4))/2 = (1+5, 6+4)/2 = (6, 10)/2 = (3, 5)

This repetitive arithmetic is carried out in the spreadsheet shown in the second attachment. The midpoints are ...

  D(3, 5) is midpoint of AB

  E(5, 1) is midpoint of BC

  F(3, 2) is midpoint of CA

__

The slope of a segment is found using the slope formula (or by counting grid squares). That formula is ...

  m = (y2 -y1)/(x2 -x1)

For segment AB, this is ...

  mAB = (4 -6)/(5 -1) = -2/4 = -1/2

The other slopes are calculated similarly in the spreadsheet. When the denominator is zero (a vertical line), the slope is "undefined."

  mBC = undefined

  mCA = -2

__

The slope of the perpendicular line is the opposite reciprocal of the slope of the segment.

  m⟂AB = -1/(-1/2) = 2

  m⟂BC = 0 . . . . . a horizontal line has 0 slope

  m⟂CA = -1/-2 = 1/2

__

The perpendicular bisectors of each of the sides of the triangle are shown in the first attachment. As the lesson title indicates, their point of concurrency is G(1, 1), the circumcenter of the triangle.

Answer:

  638

Step-by-step explanation:

The total number of responses is the value of a geometric series with first term 70 and common ratio 1-10% = 0.90. That sum is given by the formula ...

  Sn = a1·(1 -r^n)/(1 -r)

where r is the common ratio, n is the number of terms, and a1 is the first term.

The sum of n=23 terms of the series with a1=70 and r=0.9 is ...

  S23 = 70·(1 -0.9^23)/(1 -0.9) = 700(1 -0.9^23) ≈ 638

The model predicts 638 total responses over the first 23 days.

Answer:

Total percentage is always 100% so if its 12% for her to slip the remainder is 100-12= 88.

88% she doesn't slip.

Using Percentage, the odds against jessie slips on the ice is 88%.

A percentage is a "number or ratio that can be expressed as a fraction of 100".

According to the question,

The probability of jessie slip on the ice is 12% and the percentage is always taken as 100%.

In order to find the odds against jessie slips on the ice only if difference from 100% to 12%.

100 - 12 = 88.

Hence, the odds against jessie slips on the ice is 88 percentage.

Answer:

2. ( a + b )

Step-by-step explanation:

The (a + b)2 formula is the algebraic identity used to find the square of the sum of two numbers. To find the formula of the binomial in the form (a + b)2, we will just multiply (a + b) (a + b).

The formula for the number of tickets sold, 600 - 10·p, gives the

revenue at a given number of tickets as 600·p - 10·p².

The number of tickets sold = 600 - 10·p

The revenue = Ticket price × (600 - 10·p)

The completed table is presented as follows;

To complete the table and find out the number of concert tickets the band expects to sell and the revenue it expects to receive at the given ticket prices.

we need to use the provided information that the band predicts selling 600 - 10p concert tickets when each ticket is sold at p dollars.

The number of tickets sold = 600 - 10·p

The revenue = Ticket price × (600 - 10·p)

By plugging the value of ticket price we find the number of tickers and revenue.

If ticket price is 10.

Then plug in p =10 to find the number of tickets sold in the equation.

The number of tickets sold = 600 - 10·p

=600-10(10)

=500

Revenue = 10(600-10(10))

=10(500)

=5000

Similarly we fill the table by using this format.

Answer:

The expression that represents how much more Elena spent is $3.2 + p

Step-by-step explanation:

Answer:

a = 2/5

Step-by-step explanation:

a + 1/10 = 5/10

Subtract 1/10 from both sides of the equation.

a + 1/10 = 5/10

-1/10 -1/10

a = 4/10

This answer is not incorrect but we usually need to simplify it if possible.

4/10 can be reduced to 2/5.

a = 2/5

Answer:

a=2/5

Step-by-step explanation:

To solve this, we first need to isolate the a so we can solve from there

First, we subtract 1/10. But whatever we do to one side we have to do to the other side. So when we subtract 1/10 from the left side we cancel it out and we subtract 1/10 from the right side so 5/10-1/10

So our equation becomes…

a=5/10-1/10

We can simplify this to…

a=4/10

4/10 is equal to 2/5

So that is our final answer

Now since we have nothing else to do that is our final answer
