Can someone help me please

Answer:

The three main types of geography are physical, environmental and human geography. There are other sub-branches of geography such as political geography, historical geography and religious geography.

Physical geography deals with the study of Earth and its structure. The landforms, continents, oceans and tectonic movements are a part of physical geography. The formation of rocks, weathering, forces of erosion, winds, ocean currents and rivers are all studied as a part of physical geography. Environment geography deals specifically with the study of the interaction of plants and animals with Earth. Human geography focuses on how human societies flourish with the help of natural resources. It deals with the study of the evolution of cultures and religious beliefs. Economic, cultural and political geography are sub-branches of human geography.

Step-by-step explanation:

If the lines l1 and l2 are parallel, then the slope of line l2 is the same as the slope of line l1.

The slope-intercept definition of a linear function is given as follows:

y = mx + b.

For which the parameters are given as follows:

m is the slope, representing the rate of change of the function.

b is the intercept, representing the value of y when x = 0.

When two lines are parallel, they have the same slope.

Hence, If the lines l1 and l2 are parallel, then the slope of line l2 is the same as the slope of line l1.

Answer:

1. x = 4, y = 1

Graph: (See the attachment)

Step-by-step explanation:

x + 2y = 6

x - y = 3

x + 2y = 6

x = -2y + 6

x - y = 3

-2y + 6 - y = 3

-3y + 6 = 3

-3y = -3

y = 1

x = -2y + 6

x = -2 ( 1 ) + 6

x = 4

Answer:

Option A:

Yes, it is proportional because it has a constant rate of change.

Step-by-step explanation:

One trick you can use to easily tell a proportional graph is that it follows a straight line. It does not matter whether the line slopes downwards or upwards. The fact that it is straight and not cured at any point, should hint you that the graph is proportional.

Proportional graphs have a constant rate of change. The value of the slope calculated when using any two (x, y) coordinates are the same for any point along the line.

Answer:

x = 16/5

Step-by-step explanation:

9x – 6 = 4x + 10 <-- Combine like terms on one side

5x = 16 <-- Isolate x

x = 16/5

Answer: 3.2

Step-by-step explanation:

(9x - 6) = 4x + 10

9x - 6 = 4x + 10

9x = 4x + 16

5x = 16

x = 3.2

Answer:

vegetarians= 28

chickens= 44

Step-by-step explanation:

let the number of vegetarians be x

and chickens be y

So

x+2.7y=119.6----------1

x+y=72--------------2

from 2, x= 72-y

put x= 72-y in 1

72-y+2.7y=119.6

-y+2.7y=119.6-72

1.7y=47.6

divide both sides by 1.7

y=47.6/1.7

y=28

put y=28 in 1

x+28=72

y= 72-28

y=44

Answer:

Answer:

q = -2

Step-by-step explanation:

when solving 12q >= -24 you get

q >= -2 (12 divides 24 by 2)

therefore q is greater or equal to -2.

By the similarity of triangles the length of the side RS is 180 units.

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

We know in similar triangles the ratio of their corresponding sides are equal.

Given, Are two triangles OPQ and ORS.

Therefore,

OP/PR = PQ/RS.

120/360 = 60/x.

120x = 21600.

12x = 2160.

x = 2160/12.

x = 180.

Complete question :

At Alan's auto shop, it takes him 9 minutes to do an oil change and 12 minutes to do a tire change. Let x be the number of oil changes he does. Let y be the number of tire changes he does. Using the values and variables given, write an inequality describing how many oil changes and tire changes Alan can do in less than an hour ( minutes).

Answer:

9x + 12y < 120

Step-by-step explanation:

Given that:

Time taken for oil change = 9 minutes

Time taken for tire change = 12 minutes

x = number of oil changes ; y = number of tire changes

Total hours = 1 hour = 60 minutes

Number of oil and Tyre changes possible in less than an hour

(Number of oil changes * time taken) + (number of tire changes * time taken) less than 60 minutes

9x + 12y < 120

The rate at which the swimming pool is being filled is 66.6 gallons per hour

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the number of gallons be = y

Let the time taken be = x

The total volume of the pool = 15000 gallons

The pool is filled at constant rate

Now ,

The coordinate data is given as

The value of A = A ( 15 , 1000 )

The value of B = B ( 30 , 2000 )

The value of C = C ( 45 , 3000 )

Now , the rate at which the swimming pool is filled is given by the slope of the points in the line

So , the slope of the 2 points is given by the formula

Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( 2000 - 1000 ) / ( 30 - 15 )

On simplifying the equation , we get

Slope m = 1000 / 15

Slope m = 66.66 gallons per hour

Therefore , the value of A is 66.6 gallons per hour

Hence ,

The rate at which the swimming pool is being filled is given by the slope of the line where slope m = 66.6 gallons per hour

Answer:

Step-by-step explanation:

A perfect number is one whose proper divisors add up to that number.

For example, 6 is a perfect number because

Its proper divisors 1, 2 and 3 and 1+2+3 = 6.

First list prime factors:

3364 = 2 * 2 * 29 * 29

Proper divisors are 1, 2, 4, 29, 58, 116, 841, 1682

Sum of these = 2733.

So, 3364 is not a perfect number.

4489 = 67 * 67

Divisors are 1 and 67.

Sum = 68.

So, 4489 is not a perfect number.

4358 =2 * 2179

Divisors are 1 , 2 and 2179.

Sum = 2182.

So, 4358 is not a perfect number.
