How am i suppose to do this ?

Answer:

165 minutes

Step-by-step explanation:

By applying the section formula between three points A, C and B we find that the coordinate of m is ( -4, 0)

Let's suppose we have a line on which we have 3 linear dots A, C, and B respectively, in this we have to use the section formula,

Where A = x1, y1

           B = x2, y2

           C = m:n

According to the section formula

C = (mx2 = nx1) / m+n * (my2 + ny1) / m+n

Sm/ Me = 1/2

Using section formula :

the coordinates of m = (2-14)/1+2 , (-6+6) / 1+2

the coordinates of m = ( -12/3 , 0/3)    

the coordinates of m = ( - 4 , 0 )

The equation of line is (y-2) = 1/[tex]\sqrt{3}[/tex](x-2)

What is Equation of line?

The equation of a line is the algebraic representation of a line using cartesian coordinates.

The general form of the equation of a straight line is written as y = mx + cy=mx+c.

Where m is the gradient of the straight line

and c is the y-intercept of the straight line.

And

The equation of line passing through point ([tex]x_{1}[/tex], [tex]y_{1}[/tex]) is

(y-[tex]y_{1}[/tex]) = m (x-[tex]x_{1}[/tex])

Given line in the graph passes through (2,2).

We have to find the equation of the line.

Given, angle of inclination is 30.

m = tan (angle of inclination)

m = tan 30

m = 1/[tex]\sqrt{3}[/tex]

Therefore after substituting, equation of line

(y-2) = 1/[tex]\sqrt{3}[/tex](x-2)

In relation to the division of a whole number by a decimal, Sarah made an incorrect claim.

A number without fractions or decimals is said to be entire. Whole numbers include 1, 10, and 1000 as examples.

A decimal number is one that is made up of both integers and non-integers. Decimal numbers include 1.1, 2.2, and 100.234. A number with two digits following the decimal point is said to have two decimal places. Examples include 10.23 and 1.23

Assume that 2 is the entire number and that 2.23 is the decimal. The final value would be 4.46.

Assume that 100 is the entire number and that 2.23 is the decimal. The item is 223.

In order to find g(0), we just need to find the value of the function for x = 0.

Looking at the graph, for x = 0 we have y = 7.

Therefore g(0) = 7.

To find the value of x for g(x) = -1, let's look for the value of x where y = -1.

Looking at the graph, for y = -1, we have x = -2.

Therefore g(x) = -1 for x = -2.

Based on the equation that relates the distance traveled by the plane going from Boston to Philadelphia, the time it would take for the plane to travel 280 miles is 48 minutes

You can use the formula given to find the amount of time taken by the plane to travel 280 miles.

The formula is;

d=350t

distance travelled = 350 x time

Solving for time taken gives;

280  = 350 x time

Time = 280 / 350

Time = 0.8 hours x 60 minutes per hour

The amount of money Wally and Drake have left to save is equal to $29.96 if each one of them wanted to buy a telescope.

The amount of money left to be saved can be calculated by using an algebraic expression.

First, we determine the cost of two telescopes if each one of them wanted to buy a telescope to see the moons of Jupiter.

As the cost of one telescope is $62.48, the cost of two telescopes will be;

62.48 + 62.48 = 124.96

An algebraic expression can be given as;

95 + x = 124.96

where x is the money left to be saved.

Solving for x;

x = 124.96 - 95

x = 29.96

Hence, $29.96 is the amount left to be saved for each one of them to buy a microscope.

Considering the definition of an equation and the way to solve it, after 100 miles driven the price charged by each company will be the same.

An equation is the equality existing between two algebraic expressions connected through the equals sign in which one or more unknown values appear in addition to certain known data.

The solution of a equation means determining the value that satisfies it. In this way, by changing the unknown to the solution, the equality must be true.

To solve an equation, keep in mind:

Being "x" the number of miles driven, and knowing that:

the equation is:

Price of company A= Price of company B

40 +0.10x= 35 +0.15x

Solving:

40 - 35= 0.15x - 0.10x

5= 0.05x

5 ÷ 0.05= x

100= x

Finally, after 100 miles driven the price charged will be the same.

Since angle G and angle H are complementary angles, the value of x is 11 while angle H is equal to 39 degrees.

A complementary angle can be defined as two (2) angles or arc whose sum is equal to 90 degrees (90°).

Mathematically, a complementary angle can be calculated by using this formula:

Q + R = 90°

Where:

Q and R are measure of the angles subtended.

Substituting the given parameters into the formula, we have;

(6x - 15)° + (3x + 6)° = 90°

9x - 9 = 90°

9x = 90 + 9

9x = 99

x = 99/9

x = 11

Next, we would determine the value of H:

H = 3x + 6

H = 3(11) + 6

H = 33 + 6

H = 39 degrees.

Step-by-step explanation:

3 [tex]\frac{3}{4}[/tex] ÷ 6  Change 3 [tex]\frac{3}{4}[/tex] into an improper fraction

Another name for 1 is [tex]\frac{4}{4}[/tex] so another name for 3 is [tex]\frac{4}{4}[/tex] + [tex]\frac{4}{4}[/tex] + [tex]\frac{4}{4}[/tex] or [tex]\frac{12}{4}[/tex]

[tex]\frac{12}{4}[/tex] + [tex]\frac{3}{4}[/tex] = [tex]\frac{15}{4}[/tex]   So we now have

[tex]\frac{15}{4}[/tex] ÷ 6   or

Angles of ∠y is 45° and ∠x is 135°.

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.

Given Data

SRQ = 130°

∠R = 130°

As PR is the same line

So. angles of the line is 180°.

∠Y + ∠R = 180

∠y = 180 - 135

∠y = 45°

Now, PQ is the straight line

∠y +∠x = 180

∠x = 180-45

∠x = 135°

Angles of ∠y is 45° and ∠x is 135°.

The area of the gable if it is a triangle with two sides of 81 feet that meet at a 112 degrees angle is 3041.22 square feet

The two sides of the triangle=81

AB=AC=81 feet

∠A=112 degrees

∠BAD=∠DA =56 degrees

Here we have to use trigonometric functions

To find the height of the triangle we have to use the cos function

cos θ=Adjacent side/Hypotenuse

cos 56=Height/81

Height=81×cos 56

=45.29 feet

To find the length of the DC, we have to use the sine function

sin θ=Opposite side / Hypotenuse

sin 56=Base / 81

Base DC=81×sin 56

=67.15 feet

The base of the triangle BC=BD+DC

=67.15+67.15

=134.3 feets

The area of the triangle=(1/2)×b×h

Where b is the base and h is the height

=(1/2)×134.3×45.29

=3041.22 square feet

In the illustration above, a circle with a few lines intersecting at various locations is shown. So, if we split the circle in half, the resulting semicircle has a vertical angle of 180 degrees. Since ∠ROP = 125°, ∠POS = 55° is obtained by taking 180° away from 125°. ∠POS and ∠QOR are equivalent terms. Also, ∠ROP = ∠QOS.

What is lines intersecting?

In a plane, intersecting lines are any two or more lines that cross one another. The point of intersection, which can be found on all intersecting lines, is where the crossing lines share a common point.

the characteristics of intersecting lines

The intersecting lines (two or more) never cross over at more than one location.

Any angle may be used to intersect the lines in any direction. Always larger than 0° and less than 180°, this angle is generated.

A pair of vertical angles are created by two intersecting lines. The vertical angles have the same vertex and are opposing angles (which is the point of intersection).

A tax is a mandatory financial charge or some other type of the levy imposed on a taxpayer (an individual or legal entity) by a governmental organization in order to fund government spending and the various public expenditures (regional, local, or national). Around 3000–2800 BC, the first recorded taxation was enacted in ancient Egypt. Non-compliance with the law includes failing to pay on time as well as evading or resisting taxation. Taxes can be paid in cash or labor and can be either direct or indirect.

Most nations have a tax system in place to finance public, shared, or agreed-upon national necessities as well as governmental duties.

320 Tiles of measuring 20cm*50cm will be needed to cover a wall 4m by 8m.

Let to cover the wall of dimension 4m * 8m completely with the tiles we need x number of tiles of size 20cm * 50 cm.
The area of wall must be that of total areas covered by tiles.

So,

Area of 1 Tile = 20cm * 50 cm = 1000sq. cm

Total Area of Tiles needed = 1000x sq.cm

Total Area of wall = 4m * 8m = 400 * 800 = 320000 sq. cm

So, We know that

Total Area of wall = Area of 1 Tile * x
