A lorry travels at a speed of 45 km/h for 2 hours from factory P to factory Q. Then the lorry takes 30 minutes more for its return journey. Calculate the average speed.​

According to the solving the space between Arthur and Jamie are 39.1 meters.

A coordinate system is a method for determining how to place points or other geometrical objects on a manifold, such as Euclidean space, uniquely using one or more numbers, or coordinates.

The length of the line segment bridging two locations in a plane is known as the distance between them. d=√((x2 – x1)² + (y2 – y1)²).  is a typical formula for determining the separation between two places. Any two sites on an x-y plane or coordinate plane can have their distance between them calculated using this equation.

location of Arthur is (20, 30)

location of Jamie is (45, 60)

Let's apply the rule of distance to determine how far away they are because we know that :

d = √((X₂ - X₁)² + (Y₂ - Y₁)²)

let substituting the value we get:

d = √((X₂ - X₁)² + (Y₂ - Y₁)²)

d = √((45 - 20)² + (60 - 30)²)

=   √(25)² + (30)²)

= 39.1

According to the solving the space between Arthur and Jamie are 39.1 meters.

1. The slope is -2.

2. The slope is 1.

3. cost of 1 yards fabric is $6.49.

4. The average speed is 65 miles/ h.            

The slope of a line is defined as the change in y coordinate with respect to the change in x coordinate of that line. The net change in y coordinate is Δy, while the net change in the x coordinate is Δx. So the change in y coordinate with respect to the change in x coordinate can be written as,

The slope of line is the measure of steepness or the direction of line the coordinate plane.

m = Δy/Δx

where, m is the slope

1. The co- ordinates of the graph is (0, 0) and (-1, 2)

slope = (2-0) / (-1 - 0) = 2/ (-1) = -2

Thus, the slope is -2.

2. The co-ordinates of the graph is (0, 0) and (4, 4)

slope = (4 - 0) / (4- 0) = 4/4  = 1

Thus, the slope is 1.

3. cost of 7 yards fabric = $45. 43

cost of 1 yards fabric = 45. 43/7

                                  = $6.49

4. Distance = 325 miles

Time = 5 hours

So, average speed = 325 / 5

The equation is 10x=2x+60

∠CFH=75

∠CBD= 75

We are dealing with parallel lines, which are the lines that are equidistant to each other and never meet,  will never meet, when such lines are crossed by another line called the transversal creates many angles such as corresponding angles, vertical angles, alternate interior angles, alternate exterior angles, consecutive angles.

Since, angle CBD and angle CFH are the corresponding angles and they are equal to each other, we are given CBD=2x+60 and CFH = 10x

therefore , 10x=2x+60

=>10x-2x=60

=>8x=60

x=15/2

So, the angle CBD= 2x+60= 2(15/2)+60=  75

Answer: Isolate the variable by dividing each side by factors that don't contain the variable.

Inequality Form:

x < 7/2

Step-by-step explanation: graph included in link

The graph which shows the solution of the inequality 4x + 2 < 2x + 9 is the graph B.

Linear inequalities are defined as those expressions which are connected by inequality signs like >, <, ≤, ≥ and ≠ and the value of the exponent of the variable is 1.

The given linear in equality is,

4x + 2 < 2x + 9

Find the solution set of the inequality.

Operate the like terms together.

Subtracting both sides by 2x,

2x + 2 < 9

Subtracting both sides by 2,

2x < 7

Dividing both sides by 2,

x < 3.5

Step-by-step explanation:

You want the simplified form of -2(k+1)-6k.

The process of simplifying an algebraic expression includes ...

Parentheses are removed using the distributive property. The factor outside parentheses multiplies each term inside.

  -2(k +1) -6k

  = (-2)(k) +(-2)(1) -6k = -2k -2 -6k

Terms with the same variable content can be combined by adding their coefficients. (The distributive property is involved here, too.)

8x - (x - 35) = 2x - (7 + x) is the required equation with x = -7

What is  linear equation?

At first it is important to know about algebraic expression

Algebraic expression consist of numbers and variables connected with addition, subtraction, multiplication and division.

Equation shows the equality between two algebraic expressions by connecting the two algerbraic expressions by an equal to sign.

A one degree equation is known as linear equation.

Let y be filled in the gap

The measures of the angles are given as follows:

1. p = 67º.

2. q = 27º.

To solve item 1, first we have to consider that the sum of the internal angles of a triangle is of 180º, hence we find angle x, which is the interval angle of angle p.

Hence:

x + 35 + 32 = 180

x + 67 = 180

x = 113º.

An angle and it's respective external angle are supplementary, meaning that the sum of it's measures are of 180º, hence:

p + x = 180

p + 113 = 180

p = 67º.

The internal angles are given as follows:

The sum of their measures is of 180º, hence we can simply solve for q as follows:

It takes Phindi to run almost 22 tracks to cover 12kms

Given that,

First you have to figure out the length of the track whihc is circumference of circle ,

r is the radius  of circular track which is 88m

The athlete has to run 12km on the track

Circumference of circle = 2πr

Circumference of circle = 2(3.14)(88)

                                          =552.6 meters

If she covers 552.6 m whe runs one circular track then,

1 circular track -------- 552.6 meters

The equation of the line passing through P(0, 0) perpendicular to y = -9x - 1 will be  [tex]y = \frac{1}{9}x[/tex]

The given question states that the line passes through the point P(0, 0) perpendicular to the line y = -9x - 1. We have to find out the equation of the line. We have to find the equation in slope-intercept form.

We know the slope intercept is: y = mx + b

Also, given the perpendicular line has slope m₂ = -9 according to slope-intercept form. And we know that perpendicular lines have a slope that is equal to the negative reciprocal.

So, the Slope of the line m₁ = Negative reciprocal of the slope of the perpendicular line.

=>  [tex]m_{1} = -\frac{1}{m_{2} }[/tex]

=> [tex]m_{1} = -\frac{1}{(-9)}[/tex]

=> [tex]m_{1} = \frac{1}{9 }[/tex]

We get the slope [tex]m_{1} = \frac{1}{9 }[/tex]. Also, it is given that the line passes through (0, 0) so the y-intercept b = 0. Putting these values in slope-intercept form, we get:

=> y = mx + b

Assuming the question is : How much does x liters/milimeters of oil weigh?

First, we calculate how much mass did the bottle of oil lose : 590 - 400 = 190 (grams)

Since it loses 190 grams after Sophia uses 200 milimeters of oil, 200 milimeters of oil weighs 190 grams (yes.)

-> 1 milimeter of oil weighs : 190/200 = 0.95(grams)

So, to calculate the mass of x *liters* of oil, we take 0,95 x 1000 times x.

For example : To calculate the mass of 22,5 liters of oil, we take 0,95 x 1000 x 22,5 = 21375 (g) or 21.35(kg).

A median is a segment from a vertex to the midpoint of the opposite side. There are of course three medians of a triangle; they’re concurrent, meeting at a point called the centroid.

An altitude is a segment through a vertex that’s perpendicular to the opposite side; the foot of the altitude (at the point of perpendicularity) either on the side or on the line resulting from extending the side.
