Answer:
h=94.87
Step-by-step explanation:
1. Volume of pyramid formula:
Base Edge * Height of Pyramid
2. We have variables:
V = 480, Base Edge = 10, Height of Base = 16 (Inch)
3. Plug into formula + Rearrange:
![\frac{3V}{h} =(b*h)^{2} [b^{2} *h^{2} ]](https://tex.z-dn.net/?f=%5Cfrac%7B3V%7D%7Bh%7D%20%3D%28b%2Ah%29%5E%7B2%7D%20%5Bb%5E%7B2%7D%20%2Ah%5E%7B2%7D%20%5D)
h≅94.868

Answer:
18mL of the 20% solution must be mixed with 10 mL of the 6% solution to
obtain the desired 15% solution
Step-by-step explanation:
Ignore all of the useless information til the last sentence: How many milliliters of the 20% solution must be mixed with 10 mL of the 6% solution to obtain the desired 15% solution?
Our goal is to find out how many mL of 20% solution is needed to mix with 10mL of 6% solution to achive a 15% solution.
An easy and simple way to do it is to create a system of equation:
We add in x mL of 15% solution(Which has x mL of water and 20%*x mL of salt)
The equation: 15%=(20%x+0.6)/(x+10)
After solving it we get x=18
Therefore:
18mL of the 20% solution must be mixed with 10 mL of the 6% solution to
obtain the desired 15% solution
