For this case we have the expression:
"the square root of 4" is represented algebraically as:

Then, we can express the given statement as:

They are similar terms, we can subtract:

By definition of power properties we have that:
![\sqrt [n] {a ^ n} = a ^ {\frac {n} {n}} = a](https://tex.z-dn.net/?f=%5Csqrt%20%5Bn%5D%20%7Ba%20%5E%20n%7D%20%3D%20a%20%5E%20%7B%5Cfrac%20%7Bn%7D%20%7Bn%7D%7D%20%3D%20a)
Then the expression is reduced to:

Answer:

Hello There!
145 is 23.39% of 620
<u><em>HOW TO SOLVE</em></u>
<u><em></em></u>
<u><em>Equation: Y = P% * X</em></u>
<u><em>We need to solve our equation for "P"</em></u>
<u><em>P% = Y/X</em></u>
<u><em>P% = 145/620</em></u>
<u><em>p = 0.2339</em></u>
<u><em></em></u>
<u><em></em></u>
<u><em>Convert decimal to percent:</em></u>
<u><em>Percent = 0.2339 * 100 = 23.39%</em></u>
It would sure help a lot if I could take a peek at the drawings of the triangles.
we are given

we can see that
4a is in multiple in numerator
so, we can factor it out

now, we can cancel 4a
and we get

Answer:
15 people will be served before the cooler would be empty
Step-by-step explanation:
Here, we want to know the number of persons that could be served if the total amount of water available is 7.5L and each serving is 500 milliliters
What we are going to do here is to divide the total amount of water available by the number of individual servings
Mathematically, that would be;
7.5L / 500 milliliters
So we need to convert 7.5L to milliliters
Since 1000 mL = 1L ; 7.5 L = 7.5 * 1000 = 7500 mL
So the number of people served will be;
7500/500 = 15 people
