7/10
Step-by-step explanation:
Get a common denominator
1 - 3/10
10/10 - 3/10
7/10
Answer: 68 mL
Step 1: Write volume formula
The formula for volume is often abbreviated into V=l×w×h. This stands for volume= length×width×height.
Step 2: Substitute numbers for answer in cm
To get the answer in cm, simply substitute the numbers into the equation. Then, you may simply multiple them to solve.
V=4.0 cm×8.5 cm×2.0 cm
V= 68 cm
Step 3: Add cubed symbol
Since this is referring to volume, you will need to add the cubed symbol to the end of your answer. This will appear as a number 3 above the cm on the right side.
Step 4: Convert to mL
This is a simple step once you understand the formula to convert. Luckily for us, cm cubed (cm3)= 1 mL. Because of this, the answer will remain as 68 mL
Hope this is right and it helps you!

Given:
The expression is

To find:
The value of given expression.
Solution:
We have,

![[\because \cos^{-1}(-\theta)=\pi -\cos^{-1}\theta]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Ccos%5E%7B-1%7D%28-%5Ctheta%29%3D%5Cpi%20-%5Ccos%5E%7B-1%7D%5Ctheta%5D)
![[\because \cos \dfrac{\pi}{3}=\dfrac{1}{2}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Ccos%20%5Cdfrac%7B%5Cpi%7D%7B3%7D%3D%5Cdfrac%7B1%7D%7B2%7D%5D)

![[\because \tan(\pi-\theta)=-\tan \theta]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Ctan%28%5Cpi-%5Ctheta%29%3D-%5Ctan%20%5Ctheta%5D)
![[\because \tan \dfrac{\pi}{3}=\sqrt{3}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Ctan%20%5Cdfrac%7B%5Cpi%7D%7B3%7D%3D%5Csqrt%7B3%7D%5D)
Therefore, the value of given expression is
