Biologists use a formula to estimate the mass of a
mammal's brain. for a mammal with a mass of m grams, the
approximate mass b of the brain, also in grams, is given by
b=em. find the approximate mass of the brain of a mouse
that has a mass of 64 grams.

This question is based on the formula to estimate the mass of a

mammal's brain.Therefore, the approximate mass of the brain of a mouse is 2 gm.

Given:

Mass = 64 grams

We need to calculate the  approximate mass of the brain of a mouse.

According to the question,

Let  B be the  approximate mass  of the brain in grams  and m be  the mass of a mammal's brain in grams.

By using the formula of  to estimate the mass of a  mammal's brain is,

It is given that, m = 64 grams,

Therefore, the approximate mass of the brain of a mouse is 2 gm.

The approximate mass of the brain of a mouse is 2 grams

Step-by-step explanation:

The correct question in the attached figure

Let

B -----> the  approximate mass B of the brain in grams

m ----> the mass of a  mammal's brain in grams

we know that

----> given problem

we have

substitute in the formula above

Remember that

7/12 teaspoons

fraction

Step-by-step explanation:

Amount of salt that would be used = 1 x

Convert to an improper fraction

to convert to improper fraction, take the following steps :  

1.Multiply the whole number  by the denominator

2.Add the numerator to the answer gotten in the previous step

3.divide the number gotten in the previous step by the denominator

(1 x 4) + 3 =

7/4 x 1/3 = 7/12
