A diagonal of a pentagon having length 10 cm divides it into a triangle and a rectangle. If the area of the pentagon is 70 cm and the breadth of the rectangle is 5 cm, then the height of the triangle is what?​

Answer»

Answer:

Step-by-step explanation:

Area of Pentagon = Area of Rectangle + Area of Triangle

                              = Length * BREADTH + 1/2 * BASE* Height

70  = 10 * 4 + 1/2* 10*h

=> 5h = 30

=> h = 6 cm.

THUS height of triangle is 6 cm.

There is 1350 kilogram of food material in one container . How many kilograms of food will 375 such containers contain ?​

Answer»

Answer:

given that

1 container = 1350 kilogram

Height of a right circular cylinder is h cm and base radius is r cm the curved surface area will be?​

Answer»

Step-by-step explanation:

Radius of CYLINDER (r)=7cm

Height of cylinder (h)=15cm

Curved SURFACE Area =2πrh

=2×(22/7)×7×15

=660cm

TOTAL Surface Area =2πr(h+r)

=2×(22/7)×7(15+7)

=2×22×22

=968cm^2

Sandhya ate 3/7 of a cake and megha ate 2/9 . what fraction of cake did they eat together​

Answer»

Given, sandhya ate 3/7  

           megha ate 2/9

To get the fraction of cake they AE TOGETHER equate the FRACTIONS such that they have a common denominator

So sandhya = 3/7 = 27/63   ......(x 9)

     megha  = 2/9 = 14/63     .....(x 7)

fraction of cake did they eat together​ = (27+14)/63 = 41/63

Fill in the following boxes 5/20=a/4=3/a

Answer»

\huge{\pink{\underline{\underline{Answer:-}}}}

Given:

5/20 = a/4 = 3/a

To find:

Value of a in a/4 and 3/a= ?

Solution:

5/20 = a/4

1/4 = a/4

4/4 = a

a = 1

5/20 = 3/a

1/4 = 3/a

a = 3 × 4

a = 12

Cross check value of a:

5/20 = a/4

1/4 = a/4

Substituting value of a = 1

1/4 = 1/4

Thus, value of a = 1 is correct

5/20 = 3/a

1/4 = 3/a

Substituting value of a = 12

1/4 = 3/12

1/4 = 1/4

Thus value of a = 12 is correct

Extra INFORMATION:

  • As all numbers are equal, while solving take only two equal EASY numbers to find value of a
  • Highlight the answer
  • Solve more such questions to get good hold on it

-mathematics refers to any mathematics of the peoples of Mesopotamia (modern Iraq) from the days of the early Sumerians through the Hellenistic period almost to the dawn of Christianity.[18] The majority of Babylonian mathematical work comes from two widely separated periods: The first few hundred years of the second millennium BC (Old Babylonian period), and the last few centuries of the first millennium BC (Seleucid period).[19] It is named Babylonian mathematics due to the central role of Babylon as a place of study. Later under the Arab Empire, Mesopotamia, especially Baghdad, once again became an important center of study for Islamic mathematics.

How to find factor by multiplication ?​

Answer»

Answer:

Prime Numbers

A NUMBER that can only be divided by 1 and itself is called a prime number. Examples of prime numbers are 2, 3, 5, 7, 11 and 13. The number 1 is not considered a prime number because 1 goes into everything.

Divisibility Rules

Some divisibility rules can help you FIND the factors of a number. If a number is even, it's divisible by 2, i.e. 2 is a factor. If a number's digits total a number that's divisible by 3, the number itself is divisible by 3, i.e. 3 is a factor. If a number ends with a 0 or a 5, it's divisible by 5, i.e. 5 is a factor.

If a number is divisible twice by 2, it's divisible by 4, i.e. 4 is a factor. If a number is divisible by 2 and by 3, it's divisible by 6, i.e. 6 is a factor. If a number is divisible twice by 3 (or if the sum of the digits is divisible by 9), then it's divisible by 9, i.e. 9 is a factor.

Finding Factors Quickly

Establish the number you want to find the factors of, for example 24. Find two more numbers that multiply to make 24. In this case, 1 x 24 = 2 x 12 = 3 x 8 = 4 x 6 = 24. This means the factors of 24 are 1, 2, 3, 4, 6, 8, 12 and 24.

Factor negative numbers in the same way as positive numbers, but make sure the factors multiply together to produce a negative number. For example, the factors of -30 are -1, 1, -2, 2, -3, 3, -5, 5, -6, 6, -10, 10, -15 and 15.

If you have a large number, it's more difficult to do the mental math to find its factors. To make it easier, create a table with two columns and write the number above it. Using the number 3784 as an example, start by dividing it by the smallest prime factor (bigger than 1) that goes into it evenly with no remainder. In this case, 2 x 1892 = 3784. Write the prime factor (2) in the left column and the other number (1892) in the RIGHT column.

Continue with this process, i.e. 2 x 946 = 1892, adding both numbers to the table. When you reach an odd number (e.g., 2 x 473 = 946), DIVIDE by small prime numbers besides 2 until you find one that divides evenly with no remainder. In this case, 11 x 43 = 473. Continue the process until you reach 1.
