<u>Answer</u>

18

_____________________________________________________

<u>Detailed explanation</u>

82^{2} = 6724

80^{2} = 6400


We would simply need to subtract the numbers above.


6724-6400= 324


Now, we would need to square root 324.

\sqrt{324}=18


Hence, that is how 18 would be the answer.

82^2= 80^2+ x^2

x^2= 6724-6400
x^2=324
x=18

so option 1 is correct

• Chandra bought a 2-liter bottle of
frosja888 [35]

Answer:

D

Step-by-step explanation:

1 liter = 33.8 fl oz

Hence

2 liter = 33.8 * 2 = 67.6 fl oz

Now, we need to determine, how many 8 fl oz glasses can be filled with 67.6 fl oz of juice. For that, we need to divide total amount of juice (in fl oz) by 8. We will get:

\frac{67.6}{8}=8.45

So there is enough juice to fill around 8.5 glasses, but we need to know how many FULL GLASSES can be filled, NOT PARTIAL.

Thus, we can say:

8 glasses max can be filled with 2 Liters of juice

Answer choice D is right
