Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of the line parallel to the equation above we must first find the slope of the above equation

y = - 74x - 2

Comparing with the above formula

Slope = - 74

Since the lines are parallel their slope are also the same

Slope of parallel line = - 74

Equation of the line using point (4 , -2) and slope - 74 is

y + 2 = 74( x - 4)

y + 2 = 74x - 296

y = 74x - 296 - 2

We have the final answer as

Answer:

The mean size of the shoe is 7.

Step-by-step explanation:

We are given the shoe size for all the pairs of shoes in a person closet below;

X = 7, 7, 7, 7, 7, 7, 7, 7, 7, 7.

And we have to find the mean of the data.

Let X = shoe size for all the pairs of shoes

As we know that the mean of any discrete data is given by the following formula;

               Mean, [tex]\bar X[/tex] = [tex]\frac{\text{Sum of all the observations}}{\text{Total number of observations}}[/tex]

Here, the number of observations = 10

                              =  [tex]\frac{7+7+7+7+7+7+7+7+7+7}{10}[/tex]

                              =  [tex]\frac{70}{10}[/tex]  = 7

Hence, the mean size of the shoe is 7.

Answer: Midpoint (xM, yM)  =  (4, 5)

Answer:

Step-by-step explanation:

The rate of change of number of tree y on x branches of a tree is expressed as shown;

m = Δy/Δx where;

m is the rate of change

Δy is the change in number of leaves  between 3 and 4

Δx is change in number of branches  between 3 and 4

m = Δy/Δx = y₂-y₁/x₂-x₁

From table between 3 and 4, y₂ = 100, y₁ = 75, x₂ = 4, x₁ = 3

m = 100-75/4-3

m = 25/1

m = 25

Hence the rate of change between 3 and 4 branches is 25

Answer:

The answer is below

Step-by-step explanation:

The question is not correct, the correct question is:

The regional manager of a chain of department stores created the following stem-and-leaf plot showing the number of pairs of boots at each of the stores:

I 0 I

I 1 I 7 8

I 2 I 0 5 8

I 3 I 4 4 7 8

I 4 I 0

I 5 I

I 6 I

How many department stores have more than 60 pairs of boots

Answer:

The stem and leaf plot is a table which is used to represent a value with the first and other digit as the stem while the last digit is the leaf.

From the table attached, the first column is the stem and the remaining column are the leafs. Therefore from the table, below are the pairs of boots in different stores:

17, 18, 20, 25, 28, 34, 34, 37, 38 and 40.

All the store have fewer than 60 boots. This means that the number of stores with more than 60 pairs of boots is 0

Answer: 13.5π≈42.41

Step-by-step explanation:

Basically it is asking for the circumference of this cylinder.

#1 Find the circumference of the circle base

Formula to use: 2πr

2πr=2π(1.5)=3π

---------------------------

#2 Find the area of the circle base

Formula to use: πr²

πr²=π(1.5)²=2.25π

--------------------------

#3 Find the area of body of the cylinder

Formula to use: lw

300cm=3m

l (length)= 3π (since the body of the cylinder the basing on the circumference of the circle base)

w (width)= 3

lw=3π×3m=9π

----------------------------

#4 Add all of them together

There are 2 base and one body

2.25π×2+9π=13.5π

Answer:

49 feet

Step-by-step explanation:

We solve for this using proportion

Height of Jack's house = ?? = Y

Length of the shadow of Jack's house = 56 feet

Height of a tree = 21 feet

Length of the shadow of the tree = 24 feet

Height of Jack's house/ Shadow of Jack's house = Height of a tree/ Shadow of the tree

Y/56 = 21/24

Cross Multiply

24 × Y = 56 × 21

Y = 56 × 21/24

Y = 1176/24

Y = 49 feet

Therefore, the height of Jack's house is 49 feet

Answer:

51.3°

Step-by-step explanation:

Step 1: Use tan to find angle y

o = 10

a = 8

[tex]tan()=\frac{o}{a} \\tan(y)=\frac{10}{8} \\y = tan^{-1} (\frac{10}{8})\\y = 51.3[/tex]

Therefore angle "y" is 51.3° rounded to the nearest tenth

Step-by-step explanation:

The number -1/3 belongs to the set of rational numbers.

A number -1/3 is given in the question.

We have to find out that this number belongs to which set of numbers.

What is a rational number ?

A rational number is one which can be expressed as fraction p/q of two integers where p is a numerator and q is a non-zero denominator i.e., q ≠ 0.

Let's check -1/3 belongs to which set,

We know that ,

Natural numbers are the counting numbers , so -1/3 can't be a natural number.

Also ;

-1/3 can't be a irrational number because as this number is a finite number.

Let's check if it is a rational number ;

We know that rational number can be expressed in form of p/q.

Hence ;

[tex]\frac{p}{q}[/tex] = [tex]\frac{-1}{3}[/tex] , where ; p = -1 and q = 3 i.e., q ≠0

Thus , the number -1/3 belongs to the set of rational numbers.

Let x be the no.of square feet for landscaping

Company A

Monthly consulting fee = $250

Cost of landscaping of 1 sq.feet = $10

Cost of landscaping of x sq.feet = $10x

So, Total charge by company A = 250+10x  ---1

Company B

Monthly consulting fee = $90

Cost of landscaping of 1 sq.feet = $12

Cost of landscaping of x sq.feet = $12x

So, Total charge by company B = 90+12x   ---2

Now we are supposed to find  how many square feet of landscaping will the two companies charge the same amount

So, Equate 1 and 2

[tex]250+10x=90+12x\\160=2x\\80=x[/tex]

So, the two companies charge the same amount for 80 sq.feet

Total charge by company A for 80 sq.feet = 250+10(80)= $1050

Total charge by company B for 80 sq.feet = 90+12(90)=$1170
