yes
Step-by-step explanation:
22/13 =1.69≈3.2
13/4 = 3.2
Step-by-step explanation:
Putting values of x and y
2 = 4 + 2
2 = 6
= 6-2
= 4
Answer:
![m = 10\sqrt 3](https://tex.z-dn.net/?f=m%20%3D%2010%5Csqrt%203)
![n = 10](https://tex.z-dn.net/?f=n%20%3D%2010)
Step-by-step explanation:
Required
Find m and n
Considering the given angle, we have:
![\sin(60) = \frac{Opposite}{Hypotenuse}](https://tex.z-dn.net/?f=%5Csin%2860%29%20%3D%20%5Cfrac%7BOpposite%7D%7BHypotenuse%7D)
This gives:
![\sin(60) = \frac{m}{20}](https://tex.z-dn.net/?f=%5Csin%2860%29%20%3D%20%5Cfrac%7Bm%7D%7B20%7D)
Make m ths subject
![m = 20 * \sin(60)](https://tex.z-dn.net/?f=m%20%3D%2020%20%2A%20%5Csin%2860%29)
![\sin(60) =\frac{\sqrt 3}{2}](https://tex.z-dn.net/?f=%5Csin%2860%29%20%3D%5Cfrac%7B%5Csqrt%203%7D%7B2%7D)
So, we have:
![m = 20 *\frac{\sqrt 3}{2}](https://tex.z-dn.net/?f=m%20%3D%2020%20%2A%5Cfrac%7B%5Csqrt%203%7D%7B2%7D)
![m = 10\sqrt 3](https://tex.z-dn.net/?f=m%20%3D%2010%5Csqrt%203)
Considering the given angle again, we have:
![\cos(60) = \frac{Adjacent}{Hypotenuse}](https://tex.z-dn.net/?f=%5Ccos%2860%29%20%3D%20%5Cfrac%7BAdjacent%7D%7BHypotenuse%7D)
This gives:
![\cos(60) = \frac{n}{20}](https://tex.z-dn.net/?f=%5Ccos%2860%29%20%3D%20%5Cfrac%7Bn%7D%7B20%7D)
Make n the subject
![n = 20 * \cos(60)](https://tex.z-dn.net/?f=n%20%3D%2020%20%2A%20%5Ccos%2860%29)
![\sin(60) =\frac{1}{2}](https://tex.z-dn.net/?f=%5Csin%2860%29%20%3D%5Cfrac%7B1%7D%7B2%7D)
So, we have:
![n = 20 *\frac{1}{2}](https://tex.z-dn.net/?f=n%20%3D%2020%20%2A%5Cfrac%7B1%7D%7B2%7D)
![n = 10](https://tex.z-dn.net/?f=n%20%3D%2010)
<span>The
sales tax in New Jersey is 6%. For a $16 book, what will the total cost be,
including sales tax?
Solutions:
=> 16 dollars is the amount of book
=> 6% is the sales tax which is equals to (6% / 100% = 0.06)
Let’s follow the formula to get the total amount to be paid.
=> 16 dollars * .06 = .96 dollars
Now, let’s add this together:
=> .96 + 16 dollars = 16.96 dollars.</span>
