(PLEASE HELP) Find the area of the given trapezoid.
1 answer:
240 is the answer you're looking for!
Step-by-step explanation:
To find the area, spilt the trapezoid into 3 shapes.
2 triangles (at the ends) and 1 rectangle (the center).
Let's start with the rectangle, the formula for rectangle area is:
The length of the rectangle is 12, the width is 20. Add the numbers in:
Solve:
The area of the rectangle is 240. Now solve for the Triangles.
The formula for finding the area of triangles are is:
The length of the triangle is 12. To find the width subtract 20 from 30.
L = 12, W = 10. Add in the numbers.
Use order of operations to solve, start with parenthesis:
Rember to divide it by 2 because a triangle is half of a rectangle.
Since there are two identical triangles, you don't need to solve for the other
Now, add the areas together:
Then solve:
The correct answer is 240.

Given:
Charlie bought a new computer for $450 with his credit card.
He plans to pay the minimum payment of $25 per month.
To find:
The rate of change.
Solution:
Let y be the remaining amount of loan after x months.
Initial amount of loan = $450
Payment of one month = $25
Payment of x months = $25x
Now,
Remining amount = Initial amount of loan - Payment of x months
...(i)
The slope intercept form is
...(ii)
where, m is slope and b is y-intercept.
From (i) and (ii), we get
Therefore, the rate of change is -25 dollars.
