statuscvo [17]
The answer to this question would be 152,000

In this question, you are given multiple number names and asked to add it. To answer this question, it will be easier to split the sentences into multiple parts like this:
<span>1. "14 ten thousands" mean 14 * 10,000 =140,000
</span><span>2. "12 thousands" mean 12 * 1,000= 12,000
Then, if you add them up it will be: 140,000+ 12,000= 152,000</span>

Bogdan [553]

Answer:

The absolute value

Step-by-step explanation:

we know that

The modulus of a real number, is equal to the absolute value of the real number

so

The modulus of a positive number is simply the number and the modulus of a negative number is found by ignoring the minus sign.

Then

modulus of n is always positive number .such that n belongs to real number R.

Modules of n is denoted by |n|

<u><em>Examples: </em></u>

|-4|=4

|2.5|=2.5

|-100.1|=100.1

Please help with this question ​
leonid [27]

We know that \sin(45)=\cos(45) and this is the only point when sin and cos are equal lengths. Because both \sin(45),\cos(45)=\dfrac{\sqrt{2}}{2}

Now if the sin of 30° is a half that would mean that cos of 60° is also a half.

Hope this helps.
