Which of the following is an example of the additive identity? a +(-a) = 0 a+0=0 a+0= a

UNO [17]

Answer:

a+0= a

Step-by-step explanation:

we know that

The additive identity property says that if you add a real number to zero or add zero to a real number, then you get the same real number back

Let

a -----> a real number

a+0=0+a=a

therefore

a+0= a

Two numbers have these properties:

almond37 [142]

Answer:

$12\ and\ 30$

Step-by-step explanation:

Given both numbers are greater than 6

Their HCF is 6

Their LCM is 60

The product of the HCF and LCM of two numbers is the same as the product of the numbers themselves.

Let us say those number are $a$ and $b$

$a\times b=6\times 60\\a\times b=360$

So, the product of those number is $360$

Let us factorize $360$

$360=1\times 2\times 2\times 3\times 5\times 6$

It is given that number should be greater than 6

The possible pairs of number are $(10,36)\ and\ (12,30)$

But only $(12,30)$ has LCM as 60.

So those numbers are $12\ and\ 30$

Eli attended a concert. The decibel level of the music averaged 110 decibels but varied by 28 decibels from the average. Enter a

musickatia [10]

Answer:

The decibel range is $82\leq d\leq 138$

Step-by-step explanation:

Let

d -----> the decibel level of the music

we know that

The absolute value of the difference of the decibel level of the music and its average, must be less than or equal to 28 decibels

The absolute value that represent this problem is

$\left|d-110\right|\le28$

Solve the absolute value

First solution (positive)

$+(d-110)\le28$

Adds 110 both sides

$d\le28+110$

$d\le138$

Second solution (negative)

$-(d-110)\le28$

Multiply by -1 both sides

$(d-110)\ge-28$

Adds 110 both sides

$d\ge-28+110$

$d\ge82$

therefore

The decibel range is

$82\leq d\leq 138$
