"d increased by the product of k and f" is d+kf
49/(d+kf)
The final answer is 49/(d+kf)~
Answer:
Area = 36 sq. units
Step-by-step explanation:
The 3 values you need to solve for the area are the top base length, bottom base length, and height.
Top base length = 7 . It's the distance between point A and B.
Bottom base length = 11. It's the distance between points C and D.
Height = 4. It's the perpendicular distance from the top to the bottom base.
The formula to solve the area of a trapezoid (or trapezium, I'm American) is:
A = 
Put in the numbers above for the unknowns and you will get this:
A = 
Simplify:
A= 
A = 2(18)
A = 36
So the answer is 36. Hope I helped!

= 20/20 + 7/20
= 1 + 7/20
= 1.00 + 0.35
= 1.35

List of values to remember (extras):
0.05 = 1/20 = 5%
0.10 = 1/10 = 10%
0.15 = 3/20 = 15%
0.20 = 1/5 = 20%
0.25 = 1/4 = 25%
0.30 = 3/10 = 30%
0.35 = 7/20 = 35%
0.40 = 2/5 = 40%
0.45 = 9/20 = 45%
0.50 = 1/2 = 50%
0.55 = 11/20 = 55%
0.60 = 3/5 = 60%
0.65 = 13/20 = 65%
0.70 = 7/10 = 70%
0.75 = 3/4 = 75%
0.80 = 4/5 = 80%
0.85 = 17/20 = 85%
0.90 = 9/10 = 90%
0.95 = 19/20 = 95%
1.00 = 1 = 100%
Annual premium = 30 * 28.23 = $846.90
The answer is c. 10%
We know that the antique dealer would normally charge 20% more than the price he purchased the item for. This also means that the antique dealer is making a profit of 20% on the items he sells. If the antique dealer hosts a 10% off sale, he is reducing the profit he is making from 20% to 10%.
