Mei has 8 jars of soup. Each jar contains 300 milliliters of soup. What is the smallest pot mei can use to heat all the soup? a.
NeX [460]

Answer:

Option B. 3 liters

Step-by-step explanation:

First, we shall determine the total volume of soup that Mei have. This is illustrated below:

Mei have 8 jars of soup containing 300mL each. Therefore, she has a total of = 8 x 300mL = 2400mL.

Next, we shall convert 2400mL to litres (L). This can be obtain as follow:

1000mL = 1L

Therefore, 2400mL = 2400/1000 = 2.4L

Mei have 2.4L of soup.

Since the total volume of the soup that Mei have is 2.4L, she will be needing a minimum of 3L pot to heat up all the soup.

CAN SOMEONE JUST PLEASE ANSWER THIS ASAP FOR BRAINLIEST!!’
sesenic [268]
ANSWER

The three expressions are

V = 2(9 - {b}^{3} )(9 + {b}^{3} )

EXPLANATION

We were given the volume in cubic units to

V = 162 - 2 {b}^{6}

If we factor 2, we get,

V = 2(81 - {b}^{6} )

The expression in parenthesis is a difference of two squares. But you may not recognize it at first sight.

V = 2( {9}^{2} - ({b}^{3})^{2} )

This further gives us.

V = (2)(9 - {b}^{3} )(9 + {b}^{3} )
