Women in the Workforce Using data starting with1950 and projected to 2050, the number of women(in millions) in the workforce is given by the functionP = 0.79x + 20.86, where x equals the number ofyears after 1950.a. Find the value of P when x = 70. Explain whatthis means.b. What value of x represents 2030? Use the model tofind the number of women in the workforce in 2030.(Source: U.S. Census Bureau)
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.
Women in the Workforce Using data starting with
1950 and projected to 2050, the number of women
(in millions) in the workforce is given by the function
P = 0.79x + 20.86, where x equals the number of
years after 1950.
a. Find the value of P when x = 70. Explain what
this means.
b. What value of x represents 2030? Use the model to
find the number of women in the workforce in 2030.
