Answer» Ncert solutions Grade 8 Mathematics Science Chapters in NCERT Solutions - Mathematics , Class 8 Exercises in Mensuration Question 3 Q3) The shape of a garden is rectangular in the MIDDLE and semi circular at the ends as shown in the diagram. Find the area and the perimeter of this garden [Length of rectangle is 20 – (3.5 + 3.5) metres]. Solution 3: We know that, length of the garden=20 m diameter of semicircle=7m,r=3.5m (breadth of the rectangle) Length of rectangle=20m-3.5m-3.5m20m−3.5m−3.5m =13 m Area of rectangle=length\times breadthlength×breadth =13m\times7m=13m×7m =91\ m^2=91 m 2
Area of semi-circle =\frac{1\ }{2}\times\pi\times\left(3.5\right)^2 2 1 ×π×(3.5) 2
==\frac{1}{2}\times\frac{22}{7}\times\frac{35}{10\ }\times\frac{35}{10}= 2 1 × 7 22 × 10 35 × 10 35
=19.25\ m^2=19.25 m 2
Area of garden=91+19.25+19.2591+19.25+19.25 =129.5\ m^2=129.5 m 2
Perimeter of garden=perimeter of rectangle+2(Perimeter of semicircle) Perimeter of rectangle==2\times length=2×length =2\times26=2×26 =26\ m=26 m Perimeter of semicircle==\pi r=πr =\frac{22}{7}\times3.5= 7 22 ×3.5 =\frac{22}{7}\times\frac{35}{10}= 7 22 × 10 35

HCF and LCMSUBMISSIONS 1. Three boys step off together from the same spot. Their steps measure 63 cm, 70 cm and 77 cm respectively. What is the minimum distance each should cover so that all can cover the distance in complete steps? |
|
Answer» Here, the required minimum distance will be equal to the LCM of measures of their STEPS. Step MEASURE of 1ST Boy = 63 cm Step measure of 2nd Boy = 70 cm Step measure of 3rd Boy = 77 cm LCM of 63,70,77 LCM=2 × 3 × 3 × 5 × 7 × 11 = 6930 Hence, the minimum distance each should cover so that all can cover the distance in complete steps is 6930 cm.

By what number should(- 2/3)^-1be multiplied so that the product becomes(-3/4)^-1? |
|
Answer» Answer: 8/9 Step-by-step EXPLANATION: Let's ASSUME the MISSING number to be y. We know that (-2/3)^-1 * y = (-3/4)^-1. (-2/3)^-1 can be written as -3/2 and (-3/4)^-1 can be written as -4/3. New equation : -3/2 * y = -4/3. Then y = -4/3 / -3/2. (DIVIDING both sides by -3/2). y = -4/3 * -2/3 y = 8/9. Please MARK it as the brainliest. |

Divide 3000 into two parts such that the simple interest on the first part for 4 years at 8% per annum is equal to the simple interest on the second part for 2 years at 9% per annum. |
|
Answer» Step-by-step explanation: Let the FIRST PART be Rs. x. SECOND part =(3000−x) ∴S.I. on x at 8% per annum for 4 years= x×8×421 1005025
= 25
S.I. on (3000−x) at 9% per annum = (3000−x)×9×21 10050
= 27000−9x 50
∴ 8x 25
= 27000−9x 50
=>8x= (27000−9x)×251 502
=>16x=27000−9x =>16x+9x=27000 =>x= 270001080 251
=1080 ∴First part = Rs.1080 |

What is the face value of the digit at the ones place in the number which is 5 more than the smallest 3 digit nummber |
|
Answer» Step-by-step explanation: Numbers up to 3-Digit add The numbers are broadly classified based on the NUMBER of digits. Here, we shall look at the 3-digit numbers, their formation, and the importance of numbers and place values. The digits used to form higher digit numbers are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. The place value of a 3-digit number helps in understanding the value of each of the digits. The smallest of 3-digit numbers is 100 and the largest number is 999. Learning 3-digit numbers is the building block for higher-digit numbers. Here we shall explore more about the importance, formation, and place value of numbers in numbers up to 3-digit numbers. Place Value of 3-Digit Numbers Every three-digit number’s value can be found by seeing which place value each digit has. Let us consider the number 243. The first digit at the rightmost position is said to be at units place, so they would be multiplied by 1. Hence the product is 3 × 1 = 3. Then the second number is 4, and because it is at tens place, it is multiplied by 10. The value, therefore, is 4 × 10 = 40. The third number 2 is at the hundreds place. So 2 is multiplied by 100 and its value is 2 × 100 = 200. Therefore the number is 200 + 40 + 3 = 243. Decomposing a 3-digit number: In a three-digit number, there are three place values used – hundred’s, ten’s, and units. Let us take one example to understand it better. Here, 465 is a three-digit number and it is decomposed in the form of a sum of three numbers. As 5 is at the unit's place, 60 is at the tens place and 400 is on the hundreds place. Significance of Zero in 3-digit numbers: The number zero does not make any contribution to a 3-digit number if it is placed in a position where there are no other non-zero numbers to its left. So how is 303 DIFFERENT from 033 or even 003? In 033, the values are 0 × 100 + 3 × 10 + 3 × 1 = 0 + 30 + 3= 33 which MEANS that the number actually becomes a 2 digit number i.e. 33, or in the case of 003, it becomes a single-digit number i.e. 3. In these two examples, the digits zero do not contribute any value to the number, so the numbers can be EXPRESSED as 33 or 3 as well. |
