Step-by-step explanation:

The equation equation looks incomplete. However assuming it to be 212÷34.

This becomes a simple case of division. Now forming a world problem on this equation.

Consider there are 212 chocolates to be distributed among 34 children, such that each child gets equal number of chocolates. Find how many chocolate does each child got.

Simply divide 212 by 34 to get the answer =212/34

Answer:

A = 2000.

Step-by-step explanation:

A = kB^2 where k is a constant to be found, so substituting:

500 = k * 10^2

100k = 500

k = 5.

So we have

A =  5B^2

When B = 20:

A = 5 * 20^2

= 5 * 400

= 2000.

The simplified form of the expression [tex](2x - 6)^2[/tex] is [tex]4x^2 - 24x + 36.[/tex]

To simplify the expression[tex](2x - 6)^2[/tex] expand the square.

The square of a binomial follows the formula:

[tex](a - b)^2 = a^2 - 2ab + b^2.[/tex]

The binomial is 2x - 6.

Applying the formula, we have:

[tex](2x - 6)^2 = (2x)^2 - 2(2x)(6) + (-6)^2[/tex]

Simplify each term:

[tex](2x)^2 = 4x^2[/tex]

[tex]2(2x)(6) = 24x[/tex]

[tex](-6)^2 = 36[/tex]

Substituting these simplified terms back into the expression:

[tex](2x - 6)^2 = 4x^2 - 24x + 36[/tex]

Therefore, the simplified form of [tex](2x - 6)^2[/tex] is [tex]4x^2 - 24x + 36.[/tex]

Given:

Point (7,12) is rotated 1260° counterclockwise about the origin.

To find:

The  x-coordinate of the point after this rotation.

Solution:

If a point is rotated 360 degrees then its coordinates remains unchanged.

If a point is rotated 180 counterclockwise about the origin degrees, then

[tex](x,y)\to (-x,-y)[/tex]

We know that,

[tex]1260^\circ=1080^\circ+180^\circ[/tex]

[tex]1260^\circ=3\times 360^\circ+180^\circ[/tex]

After [tex]3\times 360^\circ[/tex] rotation the coordinates of points remains same, i.e., (7,12). So, after that (7,12) is rotated 180° counterclockwise about the origin.

[tex](7,12)\to (-7,-12)[/tex]

The point (7,12) becomes (-7,-12) after rotation of  1260° counterclockwise about the origin.

Therefore, the x-coordinate of the required point is -7.

Answer:

690 - 595

Step-by-step explanation:

As we know that representation of a 3 digit number = xyz

where x [tex]\neq[/tex] 0

z is at ones place

y is at tens place

x is at hundred place

As, we have to subtract two 3 digits numbers with different hundred digits

So, Let

The hundred digit of first number be 6

The hundred digit of second number be 5

∴

Assume first number with hundred digit 6

Let the number be - 690

Now,

Assume second number with hundred digit 5

Let the number be - 595

Now,

We will check that the difference between both the numbers are less than 100 or not

Now,

690 - 595 = 95 < 100

It satisfies the condition

So, the equation becomes 690 - 595

Answer:

Two places to the right.

Step-by-step explanation:

Since theres  two zeros in 100, move the decimal two places to the right, making it 400.3.

Answer:

y=2x-2

Step-by-step explanation:

The slope-intercept form is known as y=mx+c

y= the y coordinate

m= the gradient/slope

x= the x coordinate

c= y intercept

The y intercept is when the line crosses the y axis. The graph shows the y intercept is (0,-2). This means our value of c is -2.

Now we must find the value of m. The value of m is the slope of the graph. I usually figure out the slope by doing the change in y / change in x (by counting along how many squares). The change in y is two squares up and the change in x is one square along.

Therefore, the gradient would be 2/1. This equals 2 (so m=2).

Now, we can easily substitute these values into the equation given earlier. Therefore, the equation would be y=2x-2.

Step-by-step explanation:

The main difference between communicable disease and non-communicable disease is that Communicable diseases are those diseases that can spread from person to person, whereas, non-communicable diseases are those which do not spread and are non-contagious. Communicable Disease v s.

Communicable diseases are those that are contagious but generally short-lived. Noncommunicable diseases are not contagious and can’t spread to other people; these are chronic illnesses. While communicable diseases are caused by pathogens such as bacteria and viruses, noncommunicable diseases are generally due to genetics and lifestyle.

Answer:

I believe your answer is     1. Communicable diseases can spread from person to person. Noncommunicable diseases cannot spread.

Step-by-step explanation:

Communicable diseases are the diseases which passes from one individual to another individual. They are generally caused by some bacteria, viruses or any other pathogens. For example, malaria, AIDS etc. Non-communicable diseases are the diseases which does not spread from one person to another person.
