This is how you can reach your goals. beneath some question and answer examples that you can easily make use of to supercharge your knowledge and gain insight that will help you to preserve your school studies.

## Question:

A mustard seed has a mass of about 0.002. A glass jair contains about 4.3602 x 10 ^ 4 seeds. Which is a reasonable estimate of the mass of the mustard seeds in the jar?a.(2 x 10 ^-3) x(4 x 10 ^4)= 8 x 10 ^7b.(2 x 10 ^-3) x (4 x 10 ^4)=8 x 10 ^1c. (2 x 10 ^-2) x ( 4 x 10 ^4)=8 x 10 ^6d. (2 x 10 ^-2) x (4 x 10 ^4= 8 x 10^2

## Answer:

A **reasonable estimate** for the mass of mustard seed in the jar is the *product of the mass per seed and the number of seeds* in the jar which can be **estimated** as

*Mass per seed = 0.002**Number of seeds*=

0.002 = 2 × 0.001 =

__The Number of seed can be estimated to the nearest whole number as :__

*Multiplying the estimates* :

Therefore, a **reasonable estimate** is the **option B.**

From the answer and question examples above, hopefully, they can possibly guide the student deal with the question they had been looking for and take notice of everything stated in the answer above. Then could have some sharing in a group discussion and also study with the classmate in relation to the topic, so another student also has some enlightenment and still keeps up the school learning.
