Ok so 7:12 is already in it's simplest form because there is nothing that can go into both 12 and 7 (which is a prime number). So in fraction form it would be 7/12
<span>8:10, so a number than can go into both 8 and 10? 2 can go into 8 4 times, and 10 5 times. So the fraction would be 4/5 which is in simplest form (5 is prime) </span>
<span>25:50, again, what can go into both 25 and 50? 5 can. 5x5= 25 5x10=50. The fraction would be 5/10, which can be reduced to 1/2. </span>
<span>80:60, 10 can go into both of them. 8/6 which can be reduced to 4/3 (2 goes into 8 4 times and 2 goes into 6 3 times) </span>
<span>78:780, 2 can go into 78 32 times and can go into 780 390 times. 32/390 can be reduced to 16/195, which I believe is in it's simplest form (no number can go into both 16 or 195 evenly). </span>
<span>All the other ratios are solved similarly, so I think you can do it. </span>
<span>XD hopefully I explained it correctly, but you should also ask an adult to help you and/or correct your homework when you're done.</span>
Option B:
is the equivalent expression to the given expression.
Solution:
Given expression:
![$\sqrt[4]{9} ^{\frac{1}{2}x}](https://tex.z-dn.net/?f=%24%5Csqrt%5B4%5D%7B9%7D%20%5E%7B%5Cfrac%7B1%7D%7B2%7Dx%7D)
To find the equivalent expression to the given expression.
![$\sqrt[4]{9} ^{\frac{1}{2}x}](https://tex.z-dn.net/?f=%24%5Csqrt%5B4%5D%7B9%7D%20%5E%7B%5Cfrac%7B1%7D%7B2%7Dx%7D)
Using radical rule: ![$\sqrt[n]{a}=a^{\frac{1}{n}}](https://tex.z-dn.net/?f=%24%5Csqrt%5Bn%5D%7Ba%7D%3Da%5E%7B%5Cfrac%7B1%7D%7Bn%7D%7D)
So that
.
![$\sqrt[4]{9} ^{\frac{1}{2}x}=\left(9^{\frac{1}{4}}\right)^{\frac{1}{2} x}](https://tex.z-dn.net/?f=%24%5Csqrt%5B4%5D%7B9%7D%20%5E%7B%5Cfrac%7B1%7D%7B2%7Dx%7D%3D%5Cleft%289%5E%7B%5Cfrac%7B1%7D%7B4%7D%7D%5Cright%29%5E%7B%5Cfrac%7B1%7D%7B2%7D%20x%7D)
Using exponent rule: 


![$\sqrt[4]{9} ^{\frac{1}{2}x}=9^{\frac{1}{8}x}](https://tex.z-dn.net/?f=%24%5Csqrt%5B4%5D%7B9%7D%20%5E%7B%5Cfrac%7B1%7D%7B2%7Dx%7D%3D9%5E%7B%5Cfrac%7B1%7D%7B8%7Dx%7D)
Hence
is the equivalent expression to the given expression.
Option B is the correct answer.
Answer:
problem 1: h=a/b problem 2: 5
Step-by-step explanation:
First problem: a=bh
First you have to flip the equation so bh=a
Next you have to divide both sides by b.
bh/b=a/b
so h=a/b
Second problem: 45ft is the area and 9ft is the base so to find the height you have to divide the area by the base
If you only have the base and height you would multiply them to find the area. If you only have area and height you divide area by height to get base.
You have to divide 45 by 9, the answer would be 5.
Hope this helped!
