Answer:

B. 2.2

Step-by-step explanation:

Volume of a rectangular prism = length*width*height

You can replace the width with the variable x for now, the height is given in the problem, and the length is 4 times the width so in this case it's 4x.

160 = 4x*x*8

160 = 32x^2

5 = x^2

The square root of five is about 2.2 so B is the correct answer

When Arjun makes hot cocoa, he adds 20\text{ mL}20 mL20, start text, space, m, L, end text of chocolate syrup for every 333 ounc
loris [4]

Answer:

<h3>45mL hot cocoa is more chocolatey</h3>

Step-by-step explanation:

When Arjun makes hot cocoa, if he add 20mL of chocolate syrup to 3ounces of water, let us know the equivalent chocolate in one ounces of water.

20mL = 3 ounces

x = 1 ounce

cross multiply

3x = 20

x = 20/3

x = 6.67 mL

This means he must have add 6.67mL of chocolate to 1 ounce of water.

Similarly, if 45mL is added to every 6 ounces

45mL = 6ounces

x = 1 ounce

cross multiply

6x = 45

x = 45/6

x =  7.5mL

This means he must have add 7.5mL of chocolate to 1 ounce of water.

The hot cocoa that is more chocolatey is the one with the highest amount of chocolate in 1 ounce. That is 45mL hot cocoa
