Answer:
- Set A = { 5, 25, 15, 35 }
- the set of multiples of 5
Step-by-step explanation:
Words to describe the set:
A set can also be described by just defining it using plain words. For example, the set A= {Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday} can be described using words like “the set of days of the week”. Another example can be “the set of months of the year”.
Given,
Length of the rectangle piece of fabric, l = 5 yards
Width of the rectangular piece of fabric, b = 19 inches
To find,
The length of the diagonal.
Solution,
The relation between Yards and inches is :
1 Yard = 36 inches
5 yards = 180 inches
Let x be the diagonal. It can be calculated as :
Hence, the length of the diagonal is 181 inches
For this problem, we have to set up the formula for the equation first. The equation should help us predict how long would it take to reach a life expectancy of 130 years. Let's start by denoting variable to present them in algebraic equations. Let x be the number of decades, while y is the number of years for life expectancy. The base year used here is 2009 with a life expectancy of 80 years. So, we will expect that 80 is a constant in the expression. We will add to this the number of decades multiplied by 5.4, because it stands for 5.4 additional years per decade. When you write this in an equation, it would be
y = 80 + 5.4x
Now, we substitute y=130.
130 = 80 + 5.4x
x = (130 - 80)/5.4
x = 9.259
Therefore, it would take approximately more than 9 decades. Projecting this amount of time from 2009, the year would be:
Projected year = 2009 + 9 decades * (10 years/1 decade)
Projected year = 2101
It would be in year 2101.
