Juan bought a MP3 player for $45 after a 15% discount.

Answer:

The dimensions of the helmet box are as follows

Width is 9 inches

Length is 9 inches

Height is 8 inches

The dimensions of the shipping box ordered are as follows;

Width is 11 inches

Length is 13 inches

Height is 8 inches

Step-by-step explanation:

8(n + 2)(n + 4) = 1144

8·n² + 48·n + 64 = 1144

8·n² + 48·n - 1080 = 0

8×(n - 9)×(n + 15) = 0

∴ n = 9 or -15 inches

The dimensions of the helmet box are as follows

Width = 9 in.

Length = 9 in.

Height = 8 in.

The dimensions of the shipping box ordered are as follows;

Width = 9 + 2 = 11 in.

Length = 9 + 4 = 13 in.

Height = 8 in.

Answer:

8 inches x 11 inches x 13 inches

I got correct on edmentum

Answer:

f = 6, g = 8

Step-by-step explanation:

The area of Δ ADE = 60 - 48 = 12 cm²

Thus

[tex]\frac{1}{2}[/tex] AD × 4 = 12, that is

2AD = 12 ( divide both sides by 2 )

AD = 6 = f

The area of ABCD = 48 cm² , thus

fg = 48 , that is

6g = 48 ( divide both sides by 6 )

g = 8

Thus f = 6 and  g = 8

Answer: 1/16 of a pound

Step-by-step explanation:

Here is the complete question:

Jordan bought 9/16 of a pound of sunflower seeds and divided them evenly into 9 snack bags for his lunch. What is the weight of sunflower seeds in each snack bag?

1/16 of a pound

1/9of a pound

16/81 of a pound

81/16 pounds

From the question, we are told that Jordan bought 9/16 of a pound of sunflower seeds and then divided them equally into 9 snack bags for his lunch. To get the weight of sunflower seeds in each snack bag, we will divide 9/16 by 9 snack bags. This can be written mathematically as:

= 9/16 ÷ 9

= 9/16 × 1/9

= 1/16

The weight of sunflower seeds in each snack bag will be 1/16 of a pound.

Answer:

A- 1/16

Answer:

8

Step-by-step explanation:

Expression:

(-B)2

Let's substitute the value of B into this expression:

B = -4

(-B)2

[-(-4)]2

Notice how there are two negative signs int this expression:

[-(-4)]2

Well, there is an invisible 1 behind the first negative sign.

[-(-4)]2

[-1(-4)]2

All we have to do now is multiply:

[-1(-4)]2

(4)2

(4)2

= 8

Therefore, the value of the expression is 8.

Answer:

8 + (5W)/ 4

Step-by-step explanation:

Plug in 2 for x

2 * 2 * 2 + (5W)/(2 + 2)

8 + (5W)/ 4

Answer:

34 packages

25 packages

Step-by-step explanation:

He needs a pair of buns for each hamburger.

He needs 200 hamburger. That means that he needs 400 buns for his picnic.

If buns come in a package of 12, the number of packages he needs is:

400 / 12 = 33.33 packages

Because packages come in whole numbers, we have to round up.

That means he needs 34 packages.

If buns come in a package of 16, the number of packages he needs is:

400 / 16 = 25 packages

Answer:

2,8,8

Step-by-step explanation:

The class interval 20 <h < 30  contains the median.

To find the interval in which median is lies, first we have to find the cumulative frequency.

The table is,

Height range                   frequency                     Cumulative frequency

0<h < 10                               1                                        1

10 <h < 20                            9                                        1 + 9 = 10

20 <h < 30                           7                                       10 + 7 = 17

30 <h < 40                           13                                       17 + 13 = 30

                                      Sum = 30

Since, the sum of frequency is even. So that the median is ,

                    [tex]\frac{\frac{n}{2} th +(\frac{n}{2} +1)th}{2} =\frac{15th +16th}{2}[/tex]

From observing table, 15th and 16th term lies in cumulative frequency of 17.

Thus, the class interval 20 <h < 30  contains the median.

Answer:Initiation fee is $400 while monthly fee is $10

Step-by-step explanation:

Let the initial fee be x which is fixed while the monthly fee be y

At the end of 5 months, 450 was paid

This means that;

x + 5y = 450 ••••••••(i)

At the end of 10 months, $500 was paid

Mathematically, this means that;

x + 10y = 500•••••••••••(ii)

now we solve both equations simultaneously to get the value of x and y

our equation ii can be rewritten as;

x + 5y + 5y = 500

we can now insert equation i directly into this

450 + 5y = 500

5y = 500-450

5y = 50

y = 50/5

y = $10

From x + 5y = 450

let’s insert the calculated value of y

x + 5(10) = 450

x + 50 = 450

x = 450-50

x = $400

Answer:

414 9/16 m³

[tex]414\frac{9}{16}m^{3}[/tex]

Step-by-step explanation:

The volume of a Rectangular prism is calculated as Length × Width × Height

From the attached diagram,we can see that

The length = 8 3/8 m

The width = 6 m

The height =8 1/4 m

Converting the mixed fraction to improper fraction in other to simplify it better

The length = 67/8 m

The height = 33/4 m

The volume of the rectangular prism =

67/8 m × 6m × 33/4m

= (13266/32)m³

= 6633/16 m³

= 414 9/16 m³

Answer:

x = 2, x = 9

Step-by-step explanation:

Given

x² - 11x + 18 = 0

Consider the factors of the constant term (+ 18) which sum to give the coefficient of the x- term (- 11)

The factors are - 9 and - 2 , since

- 9 × - 2 = + 18 and - 9 - 2 = - 11 , thus

(x - 9)(x - 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 2 = 0 ⇒ x = 2 ← lesser value

x - 9 = 0 ⇒ x = 9 ← greater value

Answer:

The 99th tower contains 9900 blocks.

Step-by-step explanation:

From the question given, we were told that the nth tower is formed by stacking n blocks on top of an n times n square of blocks. This implies that the number of blocks in n tower will be:

n + n²

Now let us use the diagram to validate the idea.

Tower 1:

n = 1

Number of blocks = 1 + 1² = 2

Tower 2:

Number of blocks = 2 + 2² = 6

Tower 3:

Number of blocks = 3 + 3² = 12

Using same idea, we can obtain the number of blocks in the 99th tower as follow:

Tower 99:

n = 99

Number of blocks = 99 + 99² = 9900

Therefore, the 99th tower contains 9900 blocks.

Answer:

-21. -19.-17

Step-by-step explanation:

Let x be the smallest

x+2 next smallest

x+4 be the largest

4*(x) = 18+6(x+4)

Distribute

4x = 18+6x+24

Combine like terms

4x = 42+6x

Subtract 6x from each side

-2x = 42

Divide by -2

-2x/-2 = 42/-2

x = -21

x+2 = -19

x+4 = -17

Answer:

- 21, - 19, - 17

Step-by-step explanation:

Let y be the smallest no.

& y + 2 next smallest no.

& y + 4 be the largest no.

= 4 * (y) = 18 + 6 * (y + 4)

4y = 18 + 6y + 24

4y - 6y = 42

- 2y = 42

= - 21

The other 2 numbers are:

y + 2

= - 19

y + 4

= - 17

Answer:

1/2 litros es igual a la capacidad que le pidió su mamá.

Step-by-step explanation:

Para encontrar la respuesta debes escribir 0.5 como fracción. Para hacerlo, el numerador es el número original sin el punto decimal y para definir el denominador debes determinar cuántos digitos decimales tienes. En este caso, el número tiene un dígito decimal, por lo cual el denominador es 10. De acuerdo a esto:

0.5 se escribiría como [tex]\frac{5}{10}[/tex] y esta fracción se puede simplificar porque los dos números son divisibles entre 5:

5/5= 1

10/5= 2

Por esto, 0.5= [tex]\frac{1}{2}[/tex]

Esto significa que 1/2 litros es igual a la capacidad que le pidió su mama.
