Real Life Applications

Shabi is preparing a medication for a patient and needs to ensure the correct dosage. The connection between measurement and pharmacy in this scenario is:

• Measurement is not related to pharmacy.

• Measurement is crucial for accurate dosage and formulation.

• Measurement is only used in laboratory settings.

• Measurement is only important for inventory management.

In a laboratory experiment, Zubaida and Minahil are conducting a time-sensitive reaction. This is significant because:

• they ensure accurate timing of experiments.

• they allow for more flexible scheduling.

• they reduce the need for supervision.

• they increase the cost of experiments.

In a collaborative science project, Minahil and Ayesha are working in different laboratories. They realize that international standards play a crucial role in the importance of practical units in a laboratory because they:

• Ensure consistency and reliability in measurements across different labs.

• Are only applicable to large-scale industrial laboratories.

• Do not affect the accuracy of laboratory results.

• Are optional and can be ignored by laboratories.

Zubaida and Ayesha are learning about scientific notation in their math class. They are trying to express the distance from Earth to a distant star, which is 40,000,000,000,000 kilometers, in scientific notation. The exponent in scientific notation is determined based on:

• the number of significant figures in the original number

• the number of decimal places in the original number

• the number of times the original number is multiplied by 10 to become a number between 1 and 10

• the number of digits in the original number

Noor and Ayesha are working on a science project. They need to convert the population of a city, which is 4,750,000, into scientific notation. Fill in the blank: 4.75 x 10^___. Since the population is greater than 1, the exponent is positive.

• 6

• 5

• 7

• 8

Minahil is measuring the distance between two cities. The distance is given in scientific notation as 3.2 x 10^4 kilometers. To convert this distance to standard form, what should Minahil do with the decimal point for the positive exponent of 10?

• A) Move decimal point to the left

• B) Move decimal point to the right

• C) Keep the decimal point in the same place
