Long division is a common division procedure in mathematics that may be used to divide multi-digit Hindu-Arabic numbers (Positional notation) and is easy enough to do manually. A division problem is divided up into a number of simpler steps.

Like in every division problem, the dividend and divisor are two numbers that are divided to produce the quotient, which is the final product. It makes it possible to carry out computations involving arbitrary large numbers by adhering to a set of straightforward processes. When the divisor contains only one digit, long division is nearly always avoided and instead, the condensed version, known as short division, is employed. A less mechanical approach to long division is known as "chunking," which is also known as the "partial quotients method" or "hangman method."

The value of x is 4.

When two parallel lines are intersected by a transversal, the exterior angles created on either side of the transversal are equal, according to the alternate exterior angle theorem.

The given angles are 2x + 19° and x + 23°.

As these pair of angles are created on the outer side of the parallel lines but on the other side of the transversal, they are alternate exterior angles.

Using the Alternate Exterior Angles Theorem,

2x + 19° = x + 23°

2x - x = 23° - 19°

x = 4

The area ratio is 100:49.

The ratio of areas equals the ratio of squares of matching sides.

Let's put this fraction of comparable ratios into an equation and then input in our two known values to get our two unknown values:

(10)2 : (7)2 = 100 : 49

The ratio of two identical figures areas is equal to the square of the ratio of their corresponding sides.

For instance, if the ratio of the respective widths of two comparable rectangles is 2:3, the ratio of their areas is

22:32=4:9: 2 = 4: 9

Answers:

Slope intercept equation is y = -4x - 17

The point (-6, 7) is on the graph of the line.

====================================================

Explanation:

Let's solve for y

y - 7 = -4(x+6)

y - 7 = -4x - 24

y = -4x - 24 + 7

y = -4x - 17

It is now in slope intercept form y = mx+b

m = -4 = slope

b = -17 = y intercept

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

Compare the equation y - 7 = -4(x+6) with the point-slope form of y-y1 = m(x-x1)

The (x1,y1) is a point the line goes through.

Rewriting x+6 into x-(-6) has us get y - 7 = -4(x-(-6))

We can see that x1 = -6 and y1 = 7

Therefore, the point (x1,y1) = (-6,7) is on the line.

Carson will make $686.25 in a week.

This problem can be solved by using percentage.

Percentage is the measure of a quantity with respect to its whole.

Given,

The total salary of Carson in a week is = $450

Also he gets a commission of 15% on making sales for a week.

In a week he makes a sales of $1575.

Commission for this week = 15% of 1575

                                           = $236.25

Total salary for this week = 450+236.25

                                          = $686.25

So, Carson will receive the above amount in a week as his salary.

Hence, Carson will make $686.25 in a week.

The ratio of the area of the original photo to the area of the enlarged photo is 2.253

What is rectangle ?

It is a common geometrical shape having 4 sides and four vertices and each side making 90 degree with the adjacent side.

Surface area of rectangle is given as :

s = 2(lb+bh+hl)

Volume of rectangle is given as :

V= lbh

Area of rectangle is given as ;

A = lb

If a rectangular photo measures 18cm by 7cm initially, the area of the photo before enlargement will be expressed as :

A1 = Length * breadth

A1 = 18 x 7

A1 = 126 cm²

If the photo is enlarged in the ratio 2:3 then increase/decrease in length and breadth will be :

2 : 3 = 2/3 = 0.66

This is 33% decrease of its dimensions’ measurements.

Length of the photo after decrement = 18 x 2/3 = 12 cm

breadth of the photo after decrement = 7 x 2/3 = 4.66 cm

Area of the decreased photo A2 = 12 x 4.66 cm² = 55.92 cm²

The  ratio of the area of the original photo to the area of the enlarged photo = A1/A2 = 126 / 55.92

Have a great day!

Answer:

This is a linear function and you have to rewrite the equation to the standard form y= mx+q, so y= -4x + 3 where -4 is m and tells you the slope of the function while 3 tells you where it intercepts the y axis. Now you have to write the points of the function taking some x values and obtaining the relative y. For example if x is 0 then y= 3-4(0) which is equal to 3. If x is 1 y is -1, if X is 2 then y is -5 and you continue like that until you want. However, to draw the line you could just stop to two points.

The arc corresponding to a central angle of 65 in a circle of radius 10 feet measures 11.34 feet.

What is Arc of circle?

The arc of circle is defined as the segment of the circumference of a circle.

Given that;

Central angle = 65°

Radius of a circle = 10 feet.

Now, To find arc of circle, we change measure of angle in radian as;

1 degree = π/180 radian

65 degree = 65 x π/180 radian

65 degree = 1.134 radian

Since, Arc = Angle x radius

Arc = 1.134 x 10

Arc = 11.34 feet.

Thus, The arc corresponding to a central angle of 65 in a circle of radius 10 feet measures 11.34 feet.

Length of paper left is 5 m.

What is length?

Distance is measured by length. Length is a quantity having the dimension distance in the International System of Quantities. Most measuring systems use a base unit for length from which all other units are derived. The metre is the basic unit of length in the International System of Units (SI). The greatest extended dimension of a stationary item is typically believed to be its length. This is not always the case, as it may depend on the location of the item. Height, sometimes known as vertical length or vertical extent, and width, breadth, or depth are all words used to describe the length of a stationary object. When length is the longest dimension, width or breadth generally refer to the shorter one.

The value of y in the equation 1/2 = 1/4y + 1/8 when solved is: y = 3/2(three halves).

Solving an equation implies looking for the value of the variable that would make the equation true or balanced if we plug in the value of that variable into the equation.

To solve for the value of y in the given equation, 1/2 = 1/4y + 1/8, isolate the variable of equation, y, to one side.

1/2 = 1/4y + 1/8 [given]

1/2 - 1/8 = 1/4y + 1/8 - 1/8 [subtraction property of equality]

3/8 = 1/4y

By using unitary method we get :
