Ms. wilson draws a model of the factorization of a polynomial with integer factors. her model is partially complete. a 2-column

lana [24]

The equation represented by Ms. Wilson's model is n² + 13n + 40 = (n + 8)(n + 5)

<h3>How to determine the equation of the model?</h3>

The partially completed model is given as:

| n

| n²

5 | 5n | 40

By dividing the rows and columns, the complete model is:

| n | 8

n | n² | 8n

5 | 5n | 40

Add the cells, and multiply the leading row and columns

n² + 8n + 5n + 40 = (n + 8)(n + 5)

This gives

n² + 13n + 40 = (n + 8)(n + 5)

Hence, the equation represented by Ms. Wilson's model is n² + 13n + 40 = (n + 8)(n + 5)

(b) As in part (a), how many three-digit phone prefixes are possible that do not start with 0 or 1, but contain 0 or 1 as the mi

Lubov Fominskaja [6]

Answer:

The number of 3-digit phone prefixes that do not start with 0 or 1, but contain 0 or 1 as the middle digit is 160.

Step-by-step explanation:

The phone prefix for any area is of the form X X X.

These prefixes can take values from 0 to 9.

The condition to create a phone prefix is:

The first digit cannot be 0 or 1
The middle digit is either 0 or 1.

The possible number of ways to fill the first place is 8 since 0 or 1 cannot be the first digit.

The possible number of ways to fill the second place is 2 since the middle digit can be occupied by either 0 or 1.

The possible number of ways to fill the last place is 10 since there are no condition applied to the last digit.

Then the number of phone prefixes that can be formed is = $8\times2\times10=160$

Thus, the possible number of phone prefixes possible is 160.

A new unit has been formed in the army . In this until, 1 member is a staff sergeant , 3 are sergeants,21 are PFC's and 35 are P

eduard

Answer:

93%

Step-by-step explanation:

1 + 3 + 21 + 35 = 60 = 100%

21 + 35 = 56 = x%

60 = 100%

56 = x%

60x = 56 * 100

x = 56* 100 / 60

x = 2*23*2*2*5*5 / 2*2*3*5

x = 23*2*5/3

x = 93%

Crayola makes 3 red crayons for every 2 brown crayons. On Tuesday, their factory made 1,000 more red crayons than brown. How man

miskamm [114]

Answer:

They make 2000 brown crayons on that day.

Step-by-step explanation:

Given:

Crayola makes 3 red crayons for every 2 brown crayons.

On Tuesday, their factory made 1,000 more red crayons than brown.

Now, to find the number of brown crayons they make that day.

Let the numbers of brown crayons be $x.$

So, the number of red crayons = $1000+x.$

As given, 3 red crayons for every 2 brown crayons.

So, the ratio is 3:2.

Thus, 3 is equivalent to 2.

So, 1000+ $x$ is equivalent to $x.$

Now, to get the number of brown crayons by using cross multiplication method:

$\frac{3}{2} =\frac{1000+x}{x}$

By cross multiplying we get:

$3x=2000+2x$

Subtracting both sides by 2 $x$ we get:

$x=2000.$

Therefore, they make 2000 brown crayons on that day.
