The area of ABCD is 640 cm²
<h3>What is similarity in trapezoid?</h3>
In order for two trapezoids to be similar their corresponding sides must have the same ratio. Since the largest base length in the image is and the corresponding side is , the other base must also be times greater than the corresponding side.
Given:
EF= 5 cm
AB = 20cm
Area of EFGH = 40 sq cm
Now,
As both trapezoid are similar. So, their corresponding sides must have the same ratio
EF/ AB= BC/ FG= CD/ HG= HE/ DA
So,
area (EFGH) : area(ABCD) = (EF/ AB)²
40 : area(ABCD)= (5/ 20)²
40 : area(ABCD) = 1/16
area (ABCD) =640 cm²
Hence, Area of trapezoid ABCD = 640 cm²

Answer:
X=1? and that would make EF= 15. But what are the choices?
Step-by-step explanation:
Let the number of Go-go scooter to be produced be x and that of Whip scooter y, then
Maximize: R = 3200x + 5000y
subject to:
x + y ≤ 120
3x + 6y ≤ 600
The corner points of the constraints are (0, 0), (0, 100), (40, 80), (120, 0)
For (0, 0): R = 0
For (0, 100): R = 3200(0) + 5000(100) = 500,000
For (40, 80): R = 3200(40) + 5000(80) = 528,000
For (120, 0): R = 3200(120) + 5000(0) = 384,000
Therefore, for maximum revenue, they should produce 40 Go-go scooters and 80 Whip scooters.
Solutions
Annie puts $10 into a vacation jar each week and we need to find out <span>how much will she have saved by the end of the year. To solve the problem first we have to find out how many days there are in a year and convert them into weeks.
Days in a year = 365
To find weeks divide by 7 since a week consists of 7 days.
365 </span>÷ 7 = 52
<span>
1 year has 52 weeks
our next step is to multiply 52 by 10.
52 x 10 = 520
By the end of the year she would have saved 520 dollars. </span><span />
