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
1.3/8 because there is a total of 8 marbles but only 3 of them are green.
2. A 52 deck of cards has 4 or each card not including the Jokers so it would be 4/52.
3.30 red 90 total 30/20
4. all you have to do is 4*3=12
5. 4 of each card 2 red 2 black 2 red jacks 52 cards 2/52.
6.&7. coins aren't my cup of tea all i can say is maybe google it :P
8.2 pairs of blue socks 10 total pairs 2/10 or 1/5
sorry about 6 and 7 but i still hope this helped you
Answer:
No, it is not.
Step-by-step explanation:
It can not be turned into a fraction and isn't repeating with the same number.
Answer:
go to the skating rink
Step-by-step explanation:
if multiply 5x 7 you get 35
If you add 35+15 you get 50 which is the amount of money you have. So if you chose the bowling ally you could bring 7 friends
but is you multiply 3x10 that equals 30
Add that by 20 and you get 50
let me know if its right
To obtain the total surface we have to calculate the surface of the 4 triangles and add up the areas (remember that the area of a triangle is (b*h)/2 , b is the base, h is the height ).
We will caculate first the area of the base triangle for that we considerer the fact that it is an equilateral triangle with sides of lenght 6 cm, now we calculate the height, I am going to draw please wait a moment
using the pythagorean theorem we have that
![\begin{gathered} h^2=6^2cm^2-3^2\operatorname{cm}=27cm^2 \\ h=\text{ }\sqrt[]{27\text{ }}cm \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20h%5E2%3D6%5E2cm%5E2-3%5E2%5Coperatorname%7Bcm%7D%3D27cm%5E2%20%5C%5C%20h%3D%5Ctext%7B%20%7D%5Csqrt%5B%5D%7B27%5Ctext%7B%20%7D%7Dcm%20%5Cend%7Bgathered%7D)
Then, the area of the triangle is 6*h/2 = 3h = 15.59 cm^2.
Now we calculate the area of the other 3 triangles, notice that those triangles have the same base and height so we will calculate for one of them and multiply by 3. From the image we know that the height is 15cm and the base is 6 cm so the area is 45cm^2, and 45*3 cm^2 = 135cm^2.
Finally we add up all the areas:
