If the sum of six consecutive even numbers of set A is 402. What is the sum of another set B of four consecutive numbers whose lowest number of set A?
It is 260.
What is the square root of 402?
well you could figure it out you could find out what same two numbers multiplied would equal up to it if none do do the math or get a calculator
Suppose the sphere below with radius r has a volume equal to 50 units3 Find the volume of the sphere with twice the radius?
A sphere with a volume of 50 units3 has a radius of 2.29 units. A sphere with twice the radius (4.58 units) has a volume of 402 units3.
How many three digit numbers can be formed such that the sum of the digits is 6?
21 ways assuming no leading zeros, that is the smallest possible number with three digits is 100 Otherwise if leading zeros are allowed, it is 28 ways. For three digit numbers the first digit can be 1-6. Leaving the remaining two digits to be 6-value_of_first_digit. For first digit 6, the remain two digits sum to 0 which means they can only be 00, ie the number 600 - 1 number For first digit 5, the remain two digits sum to 1 which means they can be 01 or 10, ie the numbers 501, 510 - 2 numbers For first digit 4, the remain two digits sum to 2 which means they can be 02. 11, 20, ie the numbers 402, 411, 420 - 3 numbers etc It can be seen that the number of ways of making a two digit number (with leading zeros) sum to a number less than 10 is the required sum plus 1. So for the remaining first digits, the number of ways are: 3 -> 4 ways, 2 -> 5 ways, 1 -> 6 ways. Thus the total number of ways is 1 + 2 + .. + 6 = 21 If leading zeros are permitted, so that, for example, 060 (60) and 006 (6) are considered as three digits numbers, then there are a further 7 ways with a first digit of 0, making a total 28 ways.
What is the square root of 1600?
Hi, I dont know how these questions are solved in your country. We have a few methods......One is called Prime factorisation. I hoping you are familiar with this term.Well, you can also break this number as 16 multiplied by 100= 1600. {16*100=1600}The square root of 16 is 4 and 100 is 10. {16 = 42 , 100 = 102}So, it can be written as 4 multiplied by 10.{4*10}This gives u the final answer of 40Square root of 1600= 40 {402 = 1600}.QEDAnswerThe square root is a number that times itself equals another whole number in this case, it is 40....Have a nice day. AnswerThe square root is a number that times itself equals another whole number in this case, it is 40....Have a nice day. Answerthe real answerTHE SQUARE ROOT OF 1600 IS 40
