Merriam and Emmanuel assemble a new bookshelf. Its 1ft deep,4ft wide, and 8ft tall. They assemble it flat bit when they tip it up The shelf hits the ceiling. Why does it hit the ceiling

Answers

Answer 1

The maximum dimension of the shelf is given by the space diagonal

length of the shelf.

A possible reason why the shelf hits the ceiling is because the ceiling is

less than or equal to 9 feet from the ground.

Reasons:

The maximum height of the shelf is given as follows;

The diagonal of one of the side = √(8² + 4²)

The diagonal of the completed shelve = √((√(8² + 4²))² + 1²) = 9

The maximum extension of the shelve = 9 feet

Given that the shelf touches the ceiling, we have, that maximum height of

the ceiling = 9 feet.

Therefore, the shelf touches the ceiling because, height from the floor to

the ceiling is lesser than equal to 9 feet.

You have a coupon for 25% off the price of a mystery book that sells for $7.00. You also have one for 20% off the price of a science fiction book that sells for $6.25. You have $5.00. Which book can you afford to buy? Explain.​

Answers

Answer:  you can afford to buy both

as $1.75+$1.25 adds up to $3 leaving you $2 to spare.

Step-by-step explanation-

Mystery book: 25% of 7.00= 1.75 ($1.75)

Science Fiction: 20% of  6.25=1.25 ($1.25)

Answer:

You can afford the science fiction book.

Step-by-step explanation:

How to get the amount for the 25% coupon:

$7.00 × 0.25 = $1.75

To get the price of the mystery book using the coupon:

$7.00 - $1.75 = $5.25

The mystery book will cost $5.25.

How to get the price of the 20% coupon:

$6.25 × 0.20 = $1.25

To get the price of the science fiction book using the coupon:

$6.25 - 1.25 = $5.00

The science fiction book will cost $5.00.

You can afford to buy the science fiction book because you have $5.00 and that is the price of the book.  The mystery book costs $5.25 and you only have $5, which means that you don't have enough money to buy it.

The mean of 79, 76, 55, 20, 14, 68, 30, 29, and is 52. Calculate the missing
value.

Answers

add all values together which is 371
and all the numbers plus one more is 8
which means 52x8 would be the total sum of all the numbers which is 416
so 416-371 is the last value which is 45

Answer:

Step-by-step explanation:

The mean of an equation is the average of it. For example, if I take 3, 4, and 5 and I want to find the average of it, I would add them up (12) and then divide by 3, because there are 3 terms. So the mean of 3, 4, and 5 is 4. Now in your equation, you must find another number. 79, 76, 55, 20, 14, 68, 30, 29 added up is 371. Now, because there are 8 terms, I would divide 371/8. 371/8=46.38.

I am not done. I must find the missing value. I am going to use the process of elimination to solve.  I hav etried all numbers in my calcualtor that equal a high number, and then got 468. I then divided 468 with a 97 and got 52. 52 is the Missing value.

Find the average rate of change between x=2 and x=4 for the function. F(x)=3x^3-1

Answers

Answer:

84

Step-by-step explanation:

Average rate of change between x = 2 and x = 4 is:

[f(4) - f(2)]/(4 - 2) = (3*4³ - 1 - 3*2³ + 1)/2 = 168/2 = 84

Answers

Based on the information given, the amount of money that Mary will spend more for the headband will be $1.

Since Julie spent $15 on 3 headbands, the amount per headband will be:

= $15/3 = $5

Since Mary spent $48 on 8 headbands, the amount per headband will be:

= $48/8 = $6

Therefore, we can then calculate the difference between the values that are gotten. This will be:

= $6 - $5 = $1

Therefore, the difference is $1.

Determine if the point is a solution to the system of linear equations [tex] \huge \{{ \large \begin{array}{} 2x + 3y = 2 \\ 6y = 5 - 4x \end{array}} [/tex] ​

Answers

Answer:

The system has no solutions.

Step-by-step explanation:

If you stare at it for the bit you can tell the system is impossible. Let's see why:

First of all, rewrite the second equation by bringing all unknowns on the LHS:

[tex]4x+6y=5[/tex].

Then take twice the first equation, doubling every coefficient:

[tex]4x+6y=4[/tex] See how the LHS is the same? The system is asking you to find a quantity (4x+6y) which is at the same time equal to four AND five - emphasis on that "and" - which is obviously impossible, because it implies that 4=5. So the point - which you didn't provide - is not a solution. Nor is any other point.

The rate of change is:

(8.25 - 6.00)/(5 - 4) = 2.25

Answers

Answer:

Rudolph will spend $150 on tickets to the Reindeer Games. Reserved seat tickets cost $25 and general admission
tickets cost $10. Write an equation that describes the number of tickets Rudolph can buy_How many tickets can
Rudolph buy if he buys only reserved seat tickets? Only general admission tickets?

Answers

The equation that describes the number of tickets Rudolph can buy will be 25r + 10g = 150.

Let the reserved tickets be represented by r.Let the general admission be represented by g.

Therefore, the equation will be 25r + 10g = 150.

The number of tickets that Rudolph can buy if he buys only reserved seat tickets will be:

= $150 / $25 = 6

The number of tickets that Rudolph can buy if he buys only general admission tickets will be:

= $150 / $10 = 15
