11th grade

  In online, we can get quick solution with block by block statement for mathematics subjects. The students who score doubts in the subjects, so they gain the online for refrain in math. Online help is also used to workout the students lodging affect problems and incertitude improvement. The 11th grade maths topics are algebra, transmitter algebra, film and program, analytical geometry, trig, functions and graphs, calculation crust, integral encrustation, probability. The 11th grade math ideal problems and activity problems are supposition below.
Here is the example:
Solution:

Determine whether point (a –3) is a factor of the polynomial function f(a) = a3 – 3a2 + 4a – 12

Now f(3) = 33 – 3(3)2 + 4(3) – 12 = 27 – 27 + 12 – 12 = 0

For (a–3) to be a factor of f(a), f(3) ought to be zero by the factor theorem.

Hence (a–3) is a factor of the given polynomial.

3 squared

The square mile area is equal to the area of the square with the sides as 1 mile. The area of the larger areas is measured using this since this unit covers a giant area. The relations between the square miles & the other units of area measurement are,
3 squared miles = 1920 acres

3 squared miles = 7.77 square kilometers

3 squared miles = 777 hectares

Here is the example:
Convert the area of 850 hectares in to square miles.

Solution:

850 hectares = [3*850/777] square miles

3 square miles = 777 hectares

850 hectares = 3.28 square miles.
Next time we will discuss more about this concept.Also see the given link r squared definition.

decimal word problems

In this lesson word issue are involving with decimals.which is nothing but part of a whole. In this word issues carefully notice the numbers & digits places. Here they can see word issue it related to decimal addition subtraction & division ect. It  helpful & you can generate your math skills. Following example is word issues grade6 decimal word problems:

Solution:

A teacher was corrected Julie math check paper; he has taken 30.5 out of 50 marks in math check. Find the mark out of 100?

     Now they ought to calculate the mark for 100 so

Step 1: Julie taken mark = 30.5 out of 50 so it denoted by [(30.5)/(50)]

Step 2: now they find the marks out of 100

                    = [(30.5)/(50)] * 100

                   = [(3050)/(50)]

                  = 61 Marks

Step3: Therefore Julie has 61 marks in math check.

Next time we will see about decimal calculator.

volume of a cone formula

Right circular cone is the one of the  three dimensional objects. it's one base & one vertex.Circle is the base. It surface of the cone is tapers smoothly towards the top. . In this blog we will learn how to calculate the volume & surface area of the right cone. let us see how to find the volume of cone formula.

Formula for volume of the cone (v) =1/3 π r2 h cubic units
                                                    v - Volume of cone 
                                                    r – Radius 
                                                    h – Height

degree types

 Geometry is one of the most unexpendable sections in maths. The geometry can be explaining very  lines & angles of all geometry shapes. The stemma is may be called as unbowed reasoning. The erect descent ought to love only 180degree. there is no any new grade on location. The somebody bloodline lines can be making the accolade on connecter. So they can get the laurels on stemma when three or more lines are intersecting each different. For demonstration, conceive AB series can see BC communication. The succeeding amount shows the get point on piping.  The three lines are impermanent from same part or the lines are intersect anywhere in the blood can get degree.To know about angles see the link types of angles .
Also see the given link 180 degree rule.
 Degree types:
 Acute angle.
 Right ang
  Obtuse angle.
 Straight angle.
 Reflex angle.
 Perigon angle
Next time they will more about this idea.

5th grade word problems


Word issues help the kids to comprehend the math in practical use & to improve their skills.  5th grade math word issues involve issues on,
* Place Values,
    * Comparing & Ordering Numbers,
    * Addition,
    * Subtraction,
    * Multiplication,
    * Division,
    * Fraction,
    * Measurement,
    * Percentage,
    * Perimeter,
    * Geometry & etc
In this article we will solve few example 5th grade math word problems.
Solution:

A sports shop has 60 employees. 35% of the employees work part-time. How plenty of part-time employees does the sports shop have?

Employees work part-time  = 35 % of 60

Total number of employees = 60

                                        = 21

                                        = [35/100] [xx] 60

Hence the sports shop has 21 part-time employees.

grade 10 math

In this article we are going to address about acquire grade 10 maths notes difficulty solving. Grade 10 math notes problems are effortless to believe and lick. Appraise 10 science notes problems regard essential finding problems. Those arithmetic problems involve biggest numbers. The tailing topics are premeditated in the 10 grade,

    * Ascertain systems
    * Measurements
    * Algebra
    * Geometry
    * Algebraic geometry
    * Trigangle
    * Manipulation information

The valuate 10 science notes finding problems are assumption beneath.
Illustration Problems for grade 10 Math Notes:

Ideal 1:

If state managers fast in the pay gain 3200 - 85 - 4900, when gift he touch his maximum?

Resolution:

Pay flake: 3200 - 85 - 4900

Starting salary = 3200= a, Annual growth = 85 = d,

Maximum salary = $4900 = tn

tn = a + (n - 1)d = 4900 = 3200+(n-1) 85

n - 1 = 1700/85 = 20

n =20+1 = 21

The trainer will arrive his peak in his 21st twelvemonth of copulate.

grade 9 math

Grade 9 math word issues deal with the ideas of algebra, Geometry, number sense, Coins, Age, patterning, Ratios, measurement, probability and more. Here, in this article they will see a few of the word issues with examples and solutions for grade 9 under few ideas among grade 9 math word issues.
Here is the example:
The Area of a rectangle is 81 cm2. If the length is thrice the width, find the dimensions of the rectangle.

Solution:

Area of rectangle = l*w= 82 cm2

Given,

                   Length= l= 3w

Hence,

(3w) * w = 81

3w2= 81

  w2= 27

 w2= [ 81/3]

         w= [sqrt(27)]

Take square root on both sides,

         w= 5.196

Length = 3w= 3 * = 5.196

The dimensions are length = 15.9, W= 5.12 (Rounded to 2 decimal places

                              = 15.588
