Step-by-step explanation:
1.
Rises 6 inches for every horizontal change of 16 inches
Slope = rise/run
Slope = 6/16
Slope = 3/8
2.
Rises 3 feet for every horizontal change of 12 feet
Slope = rise/run
Slope = 3/12
Slope = 1/4

Answer:
a. 4/5
b. 150 and 120
Step-by-step explanation:
To find the scale factor first find two sides that correspond and have measurements. This is the length of each rectangles which are 50 and 40.
The equation for scale factor when scaling down is
SF = Smaller Length / Longer Length
When scaling up it is
SF = Longer / Smaller
We are scaling down so we plug in our numbers.
SF = 40 / 50
Solve for SF = .8 or 4/5.
For permimiter you add all four sides. Multiply the width of the larger pool by the scale factor. 25*.8 = 20
20 + 20 + 40 + 40 = 120
25 + 25 + 50 + 50 = 150
The total cost to laminate the table top is $128.

A trapezoid is a convex quadrilateral. A trapezoid has at least on pair of parallel sides.
The first step is to determine the area of the table top.
Area of a trapezoid = 0.5 x (sum of the lengths of the parallel sides) x height
0.5 x (6 + 10) x 4 = 32 square foot
Now, multiply the area by the cost per square foot
32 x 4 = $128
