What are the 3 main types of substitution reaction?

Answer:

below

Step-by-step explanation:

Isosceles triangle have TWO equal legs....so

Leg      + leg        + base = perimeter

(4x-4)   +  ( 4x-4)   + x  = 37

9x -8 = 37

9x = 45

x = 5

There are seven images are formed If two plane mirrors are positioned at an angle of 45°.

The formula for the number of images formed by two plane mirrors placed at a certain angle is

⇒360/n

where n=angle between the mirrors

The most important thing to remember is that every time the number of images formed is only ODD numbers, if the result is even then you need to subtract 1 from that.

if it is odd u need not subtract, since the number of images ever formed is only odd.

so for an angle, of 45° the number of images formed are:

⇒360/45=8

in this case, since the images formed are even u need to subtract 1 from it i.e

8–1=7

So, the number of images formed is 7.

In class 8, students may learn about different types of equality, such as:

Political equality: This refers to the idea that all individuals have an equal say in the political process and equal representation in government.

Social equality: This refers to the idea that all individuals have the same rights and opportunities, and are treated with the same respect and dignity, regardless of their background or characteristics.

Economic equality: This refers to the idea that all individuals have access to the same economic opportunities and resources, regardless of their background or characteristics.

Educational equality: This refers to the idea that all individuals have access to quality education, regardless of their background or characteristics.

Equality of opportunity: This refers to the idea that all individuals have an equal chance to succeed and reach their full potential, regardless of their background or characteristics.

A function's range is the collection of all possible values that it can accept, and its domain is the set of all values for which the function is defined.

A value for x is said to be in the domain of a function f if it successfully allows the production of a single value y using another value for x. The following requirements are frequently verified when a function's output y-value is required to be a real number:

1. The numerator cannot be zero.

2. Even roots (square roots, etc.) radicands (expressions denoted by a radical symbol) cannot have a negative value.

3. Only positive values can be used in logarithms.

The perimeter of the polygon is found as the 42 cm.

For the shown polygon:

Points A, B, C and D are tangents on the circle.

Thus, these tangent will subtend equal length from the points.

So,

AB = 3 + 4 = 7 cm

BC = 4 + 5 = 9 cm

As, ∠B ≅ ∠D, sides must also be equal.

CD = 5 + 4 = 9 cm

DA = 4 + 3 = 7 cm

Perimeter = AB + BC + BC + BC

                 = 7 + 9 + 9 + 7

Perimeter = 42 cm

Thus, the perimeter of the polygon is found as the 42 cm.

It is called the substitution method because we substitute the value of one variable with another one and solve the equation.

By changing the value of another variable in an equation, the variable can be eliminated using this method. Thus, the elimination by substitution method is the name given to this technique.

As we are aware, the substitution approach entails solving the equation to determine the value of the variable, which is then substituted in the other equation. The elimination approach, in contrast, involves removing variables from the equation such that the equation's system can be reduced to being the function of a single variable.

If a current flows at 5 mph. A boat can travel 20 mi downstream in the same amount of time it can go 12 mi upstream. The speed of the boat in still water is 20mph.

Boat speed x mph

Current speed 5 mph

Against current x - 5 mph

With current x + 5 mph

Distance against current 12

Distance with current 20

Time = same equate the time against with time with current

If A alone can do a piece of work in 6 days and B alone in 8 days, then A and B undertook to do it for $3200 and complete the work in 3 days with the help of C, then C would be paid 400 dollars.

Therefore the answer is $400.

This is a work and time problem that can be solved using the concept of rate of work. Let's call the amount to be paid to C as "x".

A can do 1 piece of work in 6 days. Therefore, his rate of work is 1/6.

B can do 1 piece of work in 8 days. Therefore, his rate of work is 1/8.

Amount of work A and B can do in 3 days is

= 3×(1/6) + 3×(1/8)

= 3×(1/6)×(4/4) + 3×(1/8)×(3/3)

= 12/24 + 9/24

= 21/24

= 7/8

So amount of work C doing is

= 1 - 7/8

= 1/8

As C do 1/8 amount of work, the amount C would receive is

For the rate of change of 4 the two points will be A(2,8) and B(4,16).

A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.

Given that the rate of change of the linear function is 4. The coordinates of the two points will be calculated as,

Rate of change = ( y₂ - y₁ ) / ( x₂ - x₁ )

Rate of change = ( 16 - 8 ) / ( 4 - 2 ) = 8 / 2 = 4
