The sum of 3 consecutive integers is 47 more than the first integer. Find the three integers.

1 answer:

Answer:

22,23,24

Step-by-step explanation:

Well, you need to first find two consecutive integers that add up to 47, because that is the difference between the first digit and the total. This happens to be 23 and 24. Once you get these two numbers, the 22 comes intuitively, as you have to add 23 and 24 to get a difference between 22 and (22+23+24).

Let Ebe the set of all even positive integers in the universe Zof integers, and XE : Z R be the characteristic function of E.

AnnZ [28]

Answer:

$\mathbf{X_E (2) = 1}$

$\mathbf{X_E (-2) = 0 }$

$\mathbf{\{ x \in Z: X_E(x) = 1\} = E}$

Step-by-step explanation:

Let E be the set of all even positive integers in the universe Z of integers,

i.e

E = {2,4,6,8,10 ....∞}

$X_E : Z \to R$ be the characteristic function of E.

∴

$X_E(x) = \left \{ {{1 \ if \ x \ \ is \ an \ element \ of \ E} \atop {0 \ if \ x \ \ is \ not \ an \ element \ of \ E}} \right.$

For XE(2)

$\mathbf{X_E (2) = 1}$ since x is an element of E (i.e the set of all even numbers)

For XE(-2)

$\mathbf{X_E (-2) = 0 }$ since - 2 is less than 0 , and -2 is not an element of E

For { x ∈ Z: XE(x) = 1}

This can be read as:

x which is and element of Z such that X is also an element of x which is equal to 1.

∴

$\{ x \in Z: X_E(x) = 1\} = \{ x \in Z | x \in E\} \\ \\ \mathbf{\{ x \in Z: X_E(x) = 1\} = E}$

E = {2,4,6,8,10 ....∞}

A carpenter goes through 3.4 boxes of nails

jeka57 [31]

4.5 boxes of nails are required for finishing 2 tables

Step-by-step explanation:

Given:

3.4 boxes of nails are required for finishing 1.5 tables

Required:

How much boxes of nails would he use for finishing 2 tables

Solution:

We can solve using Unitary Method:

Nails needed to finish 1.5 tables = 3.4 boxes

Nails needed to finish 1 table = $\frac{3.4}{1.5}\,\,boxes$

Nails needed to finish 2 tables = $\frac{3.4}{1.5}*2 =4.5\,\,boxes$

So, 4.5 boxes of nails are required for finishing 2 tables.
