An inequality that represents the number of both kinds of DVD players that can be sold to reach or beat the sales target  is 30p+60r≥250.

An inequality in mathematics is a comparison between two numbers or other mathematical expressions that is done in an unfair manner. On the number line, it is most typically used to compare the sizes of two numbers.

A and b are not equal in either situation. These interactions are recognized as robust inequalities.

Given,

Profit gained by selling portable DVD player=$30

Profit gained by selling portable DVD recorder=$60

Let,

The number of portable DVD player=p

The number of DVD recorders=r

And also given that,

The profit must be at least $250.

Therefore, 30p+60r≥250

Hence, an inequality that represents the number of both kinds of DVD players that can be sold to reach or beat the sales target  is 30p+60r≥250.

The graph that correctly represents the function f(x) = [√(x + 3)] - 2 is; Graph D

We are given the function;

f(x) = [√(x + 3)] - 2

Remember that the argument of a square root must be zero or larger, then the minimum of the domain is the value of x such that:

x + 2 = 0

x = -2

Then the function starts at:

f(-2) = [√(-2 + 3)] - 2

f(-2) = 3

Then the graph should start at (-3, 2).

We can also identify another point by evaluating in x = 2.

f(2) = [√(2 + 3)] - 2

f(2) = -1

So the function also passes through (2, - 1).

Notice that the only graph that contains these two points is the last graph with x-intercept at 7.

Distributive property make it easier to multiply a 2 digit number t0 a 1 digit number because by using distributive property we can multiply the number place of the two digit number by one digit number and inlast we can add it , which makes the whole process easier.

According to Distributive property it helps to solve the complex problems easily either they are of 2 digit or many more . Distributive property multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

In other words, according to the distributive property, an expression of the form A (B+C) can be solved as A (B+ C) = AB + AC.

This property applies to subtraction as well.

A (B –C) = AB – AC

For example :- 19 X 6

Given :  55.7796

To Find : rounded off to 3 decimal places

Solution:

55.7796

To round off to   3 decimal places need to check digit at

4th decimal place

if  digit is 5 or greater than 5 then digit at 3rd decimal place has to be increased by  1  and all decimal places after that to be removed

if  digit is  less than 5 then digit at 3rd decimal place remains same and all decimal places after that  to be removed

55.7796

Digit at 4th decimal place is 6 which is greater than 5

Hence digit at 3rd decimal place has to be increased by 1

9 + 1 = 10  Hence 1 to be carried forward to digit at 2nd decimal place

7 + 1 = 8

Hence  number rounded off to 3 decimal places  is

55.780

55.7796 rounded off to 3 decimal places is  55.780

Using system of linear equation the number of popcorn and drinks bought are 5 and  3 respectively

In solving a system of linear equation, we have two unknown variables which we are to find. However, we can use either substitution, elimination or graphical method to solve them.

In this case, to solve this problem, we have to write out two equations and solve for the unknown variable;

let;

x + y = 8 ...eq(i)

6x + 4y = 42 ...eq(ii)

From eq(i)

x + y = 8

x = 8 - y ...eq(iii)

Put eq(iii) into (ii)

6(8 - y) + 4y = 42

y = 3

put y = 3 into eq(i)

The area of rhombus is 100m²

What is rhombus ?

A rhombus is a quadrilateral with four equal-length sides in planar Euclidean geometry. The term "equilateral quadrilateral" refers to a quadrilateral whose sides all have equal lengths.

A parallelogram is a particular instance of a rhombus. The opposing sides and angles in a rhombus are parallel and equal. A rhombus also has equal-length sides on each side, and its diagonals meet at right angles to form its shape. The rhombus is also referred to as a diamond or rhombus.

A quadrilateral with four equal sides that has the shape of a diamond is called a rhombus. In everyday life, rhombus-shaped objects can be seen. In the illustration below, two instances of rhombuses in nature are shown: a diamond and a kite.

The area of rhombus is

A = pq / 2

The  value of p is 10 and q is 20

The number of sides in the given polygon is, n=11 . The sum of all exterior angles is 360o .

An exterior angle of a triangle is created by extending one side of the triangle. The angle between the extended side and the side next to it is called an exterior angle.

What is a alternate exterior?

Alternate Exterior Angles: The pair of angles on the outside of the two parallel lines but on the other side of the transversal are known as alternate exterior angles.

Look at the area above and below the crossed lines to find outside angles. Look at that outside area for each crossed line on different sides of the transversal to locate alternative outside angles. We assume you stated that the external angles are 1, 2, 7, and 8.

When a transversal connects two coplanar lines, alternate interior angles are created. They are located on the transverse sides of the parallel lines, but on the inner side of the parallel lines. At two different locations, the transversal passes through the two lines that are coplanar.

In this question we need to find the probability for the experiment of drawing two marbles (without replacement) from a bag containing three green, three yellow, and four red marbles.

Total marbles in tha bag

= 3 green marbles + 3 yellow marbles + 4 red marbles

= 10 marbles

the probability of drawing one marble from a bag,

P1 = 1/10

Now there are 9 marbles in the bag.

So, the probability of drawing second marble would be,

P2 = 1/9

So, the required probability of drawing two marbles (without replacement) from a bag would be,

P = P1 * P2

P = 1/10 * 1/9

P = 1/90

The equation of the line is y = -1/2x + 7 which passes through the point (2, 6) and has a slope of -1/2.

What is the equation of a line?

The general equation of a straight line is y = mx + c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis. Key Point. The equation of a straight line with gradient m and intercept c on the y-axis is y = mx + c.

The equation of a line that passes through the point (2, 6) and has a slope of -1/2 can be written in the form y = mx + b, where m is the slope of the line and b is the y-intercept, which is the point where the line crosses the y-axis.

To find the equation of the line, we can use the point-slope form of a line, which is given by the equation y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope of the line.

Substituting the values for the point and the slope into this equation, we get:

y - 6 = (-1/2)(x - 2)

y - 6 = -1/2x + 1

y = -1/2x + 7
