that meteorologists approximate the duration of aparticular storm by using the formulaT = 0.07D3/2,where T is the time (in hours) that a storm of diameter D (in miles) lasts.(a) The National Weather Service reports that a storm 4 mi in diameter is headedtoward New Haven. How many minutes is the storm expected to last?(b) A thunderstorm is predicted for a farming community. The crops need at least1.5 hr of rain. Local radar shows that the storm is 7 mi in diameter. Will it rainlong enough to meet the farmers’ need?
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.
that meteorologists approximate the duration of a
particular storm by using the formula
T = 0.07D3/2,
where T is the time (in hours) that a storm of diameter D (in miles) lasts.
(a) The National Weather Service reports that a storm 4 mi in diameter is headed
toward New Haven. How many minutes is the storm expected to last?
(b) A thunderstorm is predicted for a farming community. The crops need at least
1.5 hr of rain. Local radar shows that the storm is 7 mi in diameter. Will it rain
long enough to meet the farmers’ need?
