A simple answer is that any given trapezoid with height h and length of the parallel lines a and b, is half of a parallelogram with an area of (a+b) x h. Since the trapezoid is half of this, it is h(a+b)/2
Answer:
WXYZ can not be a rectangle because consecutive sides are not perpendicular to each other.
Step-by-step explanation:
The given vertices are W(-4,3), X(1,5), Y(3,1) and Z(-2,-1).
Plot these points on coordinate plane and draw the quadrilateral as shown below.
Using this formula, we get
Now,
Here, WX and XY are two consecutive sides of quadrilateral but the product of their slopes is not equal to -1. It means they are not perpendicular to each other.
Since, all interior angles of a rectangle are right angles, therefore, WXYZ can not be a rectangle.
Number of red marbles/total number of marbles
35/(35+8+7)
35/50
7/10
The probability is 7/10
Answer:
No
Step-by-step explanation:
the graph fails the vertical line test
So you can choose any number from 11 to 19.
I'll choose 11 for now.
Then you write, 11, the number, and then spell it out, eleven.
To show how many tens and ones, you can make a place value chart. You would make two boxes, the first one for tens and the other for ones.
You would put a 1 in the tens place and a 1 in the ones place.
I hope this helps!
