The correct answer is option B. Trapezoid
In a trapezoid only one pair of sides area parallel.
a. Rhombus: It have 4 sides opposites sides are parallel and equal.
c. Rectangle :Rectangle have 4 sides opposite sides are equal and parallel. Also all angles are equal.all angles equal to 90°
d. Square : square ave 4 sides all sides are equal and parallel. Also all angles are equal.all angles equal to 90°
a)78
b)82.95
To get the amount something is marked up you just need to multiply it by
1+0.(the%)
so in this case you multiply 60 by 1.30 to get 78
To get a discount you just have to do the same but without the +1
so 88*0.15
should get you the discount amount (13.2)
which you subtract from the original number (88-13.2 = 74.8)
now to get sales tax you would multiply the 79 by 0.05 which is 3.95
and add that to the total of 78.75 since sales tax applies AFTER coupons
B) 5
Proportions:
8 ⇒ 10
20 ⇒ 5x
5x = 20*10/8
5x = 25
x = 25/5
x = 5
Given formula to find the area:
Find radius first:
The circumference in this situation would be 38 feet.
Since we need to find radius, do division to 38 by 6.28.
Our radius is 6.05
Now back to the original formula which is:
Substitute:
