Vachan Kumawat 5 years, 6 months ago

Here is your answer, lets check:- Oil in 1 can = 161/6 = 26 5/6 litres Oil require to hold = 313 1/2 = 627/2 litres Now we convert denominator to 6 by LCM. 627/2 = 1881/6 litres So, no. Of tins required = 1881 / 161 = 11.68..... So we make it round off = 12 Therefore 12 tins are needed to hold 1881/6 litres of oil

Find the square root of 13824 by prime factorisation method?

Posted by Ibadahun Syiemlieh 5 years, 6 months ago

CBSE > Class 08 > Mathematics

1 answers

Yogita Ingle 5 years, 6 months ago

After resolving the prime factors, we get

13824 = 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3 x 3 x 3

Grouping

= 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3 x 3 x 3

Taking one factor from each group

∛13824 = 2 x 2 x 2 x 3

∛13824 = 24

Yogita Ingle 5 years, 6 months ago

The Range is the difference between the lowest and highest values.

Example: In {4, 6, 9, 3, 7} the lowest value is 3, and the highest is 9.
So the range is 9 − 3 = 6.

15,since the sum of the exterior angles is always 360 degrees ,if you divide 360degrees by 24 degrees you get 15 which is the number of equal exterior angles and therefore 15 vertices and sides to the polygon.

Find the amount and the compound interest on 10000 for 1 and half year at 10% per annum compounded half yearly would this interest be more than the interest he would get if it was compounded annually

Posted by Sushma R 5 years, 6 months ago

Anusha Jain 5 years, 6 months ago

COMPOUNDED HALF YEARLY- Principal= rs. 10,000 Rate= 5% per half year Time= 3 half years. Amount=Principal(1+Rate/100)time(in power) =10,000(1+5/100) 3(in power) =10,000*105/100*105/100*105/100 =(105*105*105)/100 =11,57,625/100 =11576. 25 Compound Interest=Amount-Principal =11576.25-10,00 =1576.25 COMPOUNDED ANNUALY- Principal=10,000 Rate= 10% per annum Time= 1(1/2) years. (first, we will find the interest for 1 year and then for half year.) (As time is 1 year, the SI=CI. So, to make our calculation easier, we are going to find it in simple interest only) Simple Interst= (principal*time*rate)/100 =(10,000*1*10)/100 =1000 Amount= principal+Interest =10,000+1000 11000 (for next half year, the amount becomes principal in CI ie 11000 becomes our new principal.) Intesrest= PRT/100 =(11000*10*1)/(100*2) =110*5 =550 Thus, for 1 and a half years compounded annually, our interest comes out to be rs. 550. Comparing the Interests- 1576. 25>550 Difference = 1576.25-550 =rs. 1026.25. Thus,the compound interest will be more if the principal is compounded half yearly.

How to made a line segment

Posted by Parth Parent 5 years, 6 months ago

CBSE > Class 08 > Mathematics

1 answers

Meghna Thapar 5 years, 6 months ago

To draw a line segment of a given length, we can employ either of the given methods:

Using a ruler
Using ruler and compasses

Using a Ruler

We are required to draw a line segment of length 5 cm. The simplest method is by using a ruler. We mark two points using a ruler which are at a distance of 5 cm from each other. Then, mark the points as A and B and join them. We get a line segment AB of length 5 cm

However, it is to be noted that if we do not look straight down at the ruler, we might end up capturing an incorrect distance. A more accurate method for the same is described below.

Using Ruler and Compasses

The steps to draw a line segment of length 5 cm using ruler and compasses are:

Step 1: Draw a line of any length. Mark a point A on the line, which is the starting point of the line segment.
Step 2: Using a ruler, place the pointer of the compass 5 cm apart from the pencil’s lead.
