Answer:
12 inches
Step-by-step explanation:
The formula for a trapezoid is
A = 1/2(a +b)h
The formula to find the height =
h = 2A/a + b
A= 216 in²
a =14 in
b = 22 in
Hence,
h = 2 × 216/14 + 22
h = 12 inches
The height of the trapezoid = 12 inches
Step-by-step explanation:
x = 21/4 fraction form and alternative form is 5 1/4
70% = 70/100
divide 70 by 100
=0.7
Answer:
Step-by-step explanation
I get the same answer you do, but I'm not at all certain I'm correct. I would have done it just as you did letting each y value define the new x value and then putting the - on the left in at the very end.
f(1) = 3
f(3) = -1
f(-1) = 7
But there is a minus in front of the left most f. That would make it - 7
For this case we have the following data:
Area of the rectangle, 
Relationship of the sides 5: 3
By definition, the area of a rectangle is given by:

Where
- b: it is the side of least length.
If the sides have a 5: 3 ratio, it means:


Substituting in the formula of the area, we have:


Clearing b:

So, the sides are:
