Answer: 166 cm

Step-by-step explanation:

x / 19 = 126

* 19 * 19

x = 2394

(2394 + y) / 20 = 128

* 20 * 20

2394 + y = 2560

- 2394 - 2394

y = 166

Answer:

Step-by-step explanation:

Hello : let A(-7,3) B(-6,-1)

the slope is : (YB - YA)/(XB -XA)

(-1-3)/(-6+7) = -4/1 =-4

an equation is : y=ax+b a is a slope

y = -4x +b

the line through point B (-6,-1) : -1 = (-4)(-6)+b

b = -25

the equation is : y =-4x-25

The equation of line passes through the points (-7, 3) and (-6, -1) will be;

⇒ y = - 4x - 25

What is Equation of line?

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Two points on the line are (-7, 3) and (-6, -1).

Now,

Since, The equation of line passes through the points (-7, 3) and (-6, -1).

So, We need to find the slope of the line.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (- 1 - 3) / (-6 - (-7))

m = - 4 / (-6 + 7)

m = - 4/1

m = - 4

Thus, The equation of line with slope - 4 is,

⇒ y - 3 = - 4 (x - (-7))

⇒ y - 3 = - 4 (x + 7)

⇒ y - 3 = - 4x - 28

⇒ y = - 4x - 28 + 3

⇒ y = - 4x - 25

Therefore, The equation of line passes through the points (-7, 3) and

(-6, -1) will be;

⇒ y = - 4x - 25

Answer:

 [1]    x - y = -10

  [2]    2x + 4y = 22

Step-by-step explanation:

// Solve equation [1] for the variable  x  

 [1]    x = y - 10

// Plug this in for variable  x  in equation [2]

  [2]    2•(y -10) + 4y = 22

  [2]    6y = 42

// Solve equation [2] for the variable  y  

  [2]    6y = 42  

  [2]    y = 7  

// By now we know this much :

   x = y-10

   y = 7

// Use the  y  value to solve for  x  

   x = (7)-10 = -3

Answer:

Step-by-step explanation:

IQR is the interquartile range of the data set.

So Saul had already arranged the data in order, that is the first step when calculating the interquartile range.

25, 30, 50, 50, 50, 50, 56, n., 250

Next, is to find the median so we could easily separate the data into quartiles.

The median of the data 25, 30, 50, 50, 50, 50, 56, n., 250 = 50

Then, arrange the data into the first quartile and the third quartile

first quartile = 25, 30, 50, 50

third quartile = 50, 56, n., 250

first quartile median = 30 + 50 = 80/2 = 40

third quartile = 56 + n /2

The interquartile range formula is the first quartile subtracted from the third quartile:

IQR = Q3 – Q1.

Since 27 is the interquartile range, n=

27 = (56 + n /2) - 40

Use 2 to multiply through to eliminate the denominator

54 = (56 + n) - 80

n = 78

Answer:

Trevor has 30 more cents than Jeff.

Step-by-step explanation:

Jeff:

1 dime = 10 cents.

So we do 10x7=70.

So Jeff has 70 cents.

Trevor:

1 nickel = 5 cents

So we do 20x5 = 100 cents which is the same thing as 1 dollar.

Then we do 100 cents - 70 cents which is 30 cents.

Answer:

4p

Step-by-step explanation:

You have 3p + 2p - p

If there is a single alone p like on the end of the equation, it can be assumed that there is a 1 in front of it, even if it doesn't show it.

A letter variable that is alone means there's always like an invisible 1 in front. So, you have:

3p + 2p - 1p

Subtract 1p from 2p to get 1p, or just p.

3p + p

=4p

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

The final expression after simplifying is 4p.

21²×5 = 2205

The total number of combinations of tag codes is 2,205 tag codes

The number of ways of selecting r objects from n unlike objects is:

ⁿCₓ = n! / ( ( n - x )! x! )

where

n = total number of objects

x = number of choosing objects from the set

Given data ,

Let the total number of combinations of tag codes be A

Now , the equation will be

The number of letters in the tag codes = 3 letters

The first letter is a consonant

The total number of ways of selecting a consonant = ²¹C₁

The second letter is a vowel

The total number of ways of selecting a vowel = ⁵C₁

The third letter is a consonant

The total number of ways of selecting a consonant = ²¹C₁

The total number of combinations of tag codes A = ²¹C₁ x ⁵C₁ x ²¹C₁

On simplifying the equation , we get

The total number of combinations of tag codes A = 21 x 5 x 21

The total number of combinations of tag codes A = 2,205 tag codes

Hence , the number of combinations is 2,205
