(Use R = 3s.) Answer:____________________   Calculate the actual value of s. Answer:____________________   Is the actual value close to the estimate? Which one is the correct answer:   ____The actual value is very close to the estimate, since the difference is within 0.2. ____The actual value is close to the estimate, since the difference is between 0.2 and 0.5.     ____The actual value is not markedly different from the estimate, since the difference is between 0.5 and 1. ____The actual value is not close to the estimate, since the difference is more than 1

Unitary Method

The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products. 

Speed, Time, and Distance

Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.

Profit and Loss

The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.

Units and Measurements

Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
