What is the least common denominator of 1/4, 3/7, 1/11

1 answer:

6 0

Alright. One way you can do this is to list multiples of each denominator:

1/4:
4, 8, 12, 16, 20, 24, 28, 32, 36...... and so on

3/7:
7, 14, 21, 28, 35, 42, 49, 57, 63......

1/11;
11, 22, 33, 44, 55, 66, 77, 88......

Keep going until you see the least common denominator!

Now an easier way to do this is by multiplying all of the numbers in the denominator then get the factors:

4*7*11 = 308

And since those are not divisible by a whole number (besides 4 but 308 won't be divisible by 2*7*11)

Therefore 308 is the least common denominator.

The sum of three consecutive integers is 141. What is the smallest integer?

Sonja [21]

Answer:

The Consecutive number are 46 , 47 and 48 having sum as 141

The smallest number is 46

Step-by-step explanation:

• A consecutive numbers means number are in a sequence and are one after the another !

e.g. n , (n+1). Or 1 , 2 are consecutive numbers

• A consecutive even numbers differ by 2 because all even numbers are divisible by 2 !

• If the number is divisible by x we must had taken number as n , ( n + x ) ,

( n + 2x )

• Let the numbers be ( n - 1 ) , n and

( n + 1 )

Given ,the sum of numbers is 141

n - 1 + n + n + 1 = 141

3n = 141

n = 141/3

n = 47

So, the numbers are

n- 1 = 47 - 1 = 46

n = 47

n + 1 = 48

And , the smallest number is 46

• Verification :-

46 + 48 + 47 = 141

Which satisfies the given condition !!

Hence , verified !!

How do you get the answer for 3n+5 I’m trying to get my grade up from a C so how do you find this answer?

lana [24]

I think it’s six because 3n=6-5 3 n=6-5 then subtract 5 5 from 6 6

Write an expression to describe the sequence below. Use n to represent the position of a term in the sequence, where n = 1 for t

Marizza181 [45]

Answer:

$a_n = -2 + n$ is an expression which describe the given sequence

Step-by-step explanation:

Arithmetic sequence states that a sequence where the difference between each successive pair of terms is the same.

The general rule for the arithmetic sequence is given by;

$a_n =a_1+(n-1)d$ ......[1]

where

$a_1$ represents the first term

d represents the common difference

and n is the number of terms;

Given sequence: -1 , 0 , 1 , 2 , .....

This is an arithmetic sequence with common difference

Since,

0-(-1) = 1

1-0 =1

2-1 = 1 ....

Here, $a_1 = -1$

Substitute the value of $a_1 = -1$ , d =1 in [1] we get

$a_n = -1 +(n-1)(1)$

$a_n = -1 + n -1 = -2 +n$

Therefore,an expression which describe the given sequence is, $a_n = -2 + n$

A set of points in the xy-coordinate plane meets two conditions, as described.

Pepsi [2]

Answer:

Condition 1: y>0

Condition 2: x+y>-2

Step-by-step explanation:

We are told that we have a set of points in the Cartesian system (i.e. x-y coordinate), so we can define our point as:

$(x,y)$

We are given two conditions and we want to create a system of inequalities. Now, generally speaking, inequalities are expressions relating mathematical expressions through 'comparison' (i.e. less than, greater than, or less/greater and equal to) usually recognized by , $>$ , $\leq$ and $\geq$ , respectively.
