* HELP* A book sold 39,900 copies in its first month of release. Suppose this represents 8.2% of the number of copies sold to date. How many copies have been sold to date? Round your answer to the nearest whole number

Answers

Answer:

Total copies sold= 486,585

Step-by-step explanation:

Giving the following information:

Number of copies sold in the first month= 39,900

% of copies sold in the first month= 8.2%

To calculate the total number of copies sold, we need to use the following formula:

Total copies sold= Number of copies sold in the first month/% of copies sold in the first month

Total copies sold= 39,900 / 0.082

Total copies sold= 486,585

The Taylors have a square rug in their living room that is "x" feet long on each side. The room is 3

feet wider and 5 feet longer than the rug. Write an expression to describe the perimeter of

the living room.

Answers

Answer:

[tex]Perimeter = 4x+16[/tex]

Step-by-step explanation:

Given

[tex]Rug=x[/tex]

Required

Determine the perimeter of the room

The room is 3ft wider.

So:

[tex]Width = Rug + 3[/tex]

[tex]Width = x + 3[/tex]

The room is 5ft longer,

So:

[tex]Length = Rug + 5[/tex]

[tex]Length = x + 5[/tex]

The perimeter is:

[tex]Perimeter = 2 * (Length + Width)[/tex]

[tex]Perimeter = 2 * (x+5+x+3)[/tex]

Collect Like Terms

[tex]Perimeter = 2 * (x+x+5+3)[/tex]

[tex]Perimeter = 2 * (2x+8)[/tex]

[tex]Perimeter = 4x+16[/tex]

Hello guys I just wanted to know the answer or this problem, Meredith rented a bike from Bubba's Bike Shack. They charged $2 per hour. Meredith paid $26. Which equation could be used to find h, the number of hours Meredith rented the bike? Thanks for reading, and help me please

Answers

Since they charge $2 per hour, 2 is the variable, and x is the number of hours.

To find the number of hours after paying 26 dollars:
2x = 26

To solve for x: Divide both sides by 2
2x/2 = 26/2
1x = 13

Expand: -1/3(-2x-21)

Answers

Answer:

Step-by-step explanation:

Simplifying

3(2x + -1) = 21

Reorder the terms:

3(-1 + 2x) = 21

(-1 * 3 + 2x * 3) = 21

(-3 + 6x) = 21

Solving

-3 + 6x = 21

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '3' to each side of the equation.

-3 + 3 + 6x = 21 + 3

Combine like terms: -3 + 3 = 0

0 + 6x = 21 + 3

6x = 21 + 3

Combine like terms: 21 + 3 = 24

6x = 24

Divide each side by '6'.

x = 4

Simplifying

x = 4

Answer:

2/3x + 7s

Step-by-step explanation:

-1/3 ( -2x - 21) = -1/3 * (-2x) - (-1/3) * 21 = 2/3x - (-7) = 2/3x + 7s

Answers

Answer:

h = (3 - x)/2

Your answer is not correct.

Step-by-step explanation:

⅓(x + 2h) + 1 = 2

Subtract 1 from both sides;

⅓(x + 2h) + 1 - 1 = 2 - 1

This gives;

⅓(x + 2h) = 1

Multiply both sides by 3;

⅓(x + 2h) × 3 = 1 × 3

This gives;

x + 2h = 3

Subtract x from both sides to get;

2h = 3 - x

Divide both sides by 2 to get;

h = (3 - x)/2

Find the values of x and y

Can someone help?

Answers

Answer:

[tex](x,y) = (65^\circ, 50^\circ)[/tex]

Step-by-step explanation:

Let all values denote degrees.

By the exterior angle theorem, [tex]x + y = 115[/tex]. Moreover, because we are dealing with an isoceles triangle, [tex]y = 180 - 2x[/tex]. Substituting this into the former equation gives [tex]180-x=115[/tex] and as such [tex]x=65[/tex]. Because [tex]x + y = 115[/tex] we now also know that [tex]y=50[/tex].

Answer:

x° = 65° & y° = 50°.

Step-by-step explanation:

115° = x° + y° ( exterior angle property )

Let's name that angle to the right of 115° as 'a'.

a = 180 - 115 = 65°. (linear pair)

Now we know that the triangle is an isosceles triangle. (given)

So this makes x° also as 65° (equal sides make equal angles).

This leaves behind y°.

y° = 180 - (65+65) = 50°.

So, x° = 65° & y° = 50°.

Which is better to buy, 6 CD's for $12 or 8 CD's for $14.50?

Answers

Answer:

8 CDs for $14.50

Step-by-step explanation:

We have to divide both of the numbers by the number of CDs. Our formula is:

(price) ÷ (number of CDs) = price per CD

When we divide both of the prices by the number of CDs, we see that 6 CDs for 12.00 is worse because it is 2.00, whereas the inflation is lower when you compare to the other rate. You get $1.81.

Point B is the midpoint of AC, and point C is the midpoint of AD. If CD=12, what is AB?

Answers

Answer: AB = 6

Step-by-step explanation:

If CD = 12 , AC also = 12

B is the midpoint of AC so one side = 6

AB is one side of AC , so AB = 6

I am not a professional, I am simply using prior knowledge!

Note- It would mean the world to me if you would mark me brainliest!

The Distance between AB will be 12 units

ConceptFirst we will find the distance between point A and CAfter that we will divide the distance between A and C by 2 to find AB

What are steps to solve this problem?

The steps are as follow:

Distance between CD is given which is 12 unit To find AC we will double the distance between CD because C is midpoint of ADSo distance AC is given by:

AC = 2 x CD = 2 x 12 = 24 units

To find AB we will divide the AC by 2 because B is midpoint of ACSo distance AB is given by:

AB = AC/2

AB = 24/2 = 12 units

So Distance between points AB will be 12 units
