To find the area of a trapezoid, we use the following formula:
In this formula a represents the area and b1 and b2 each represent a base of the trapezoid.
So, we have got the following information
Filling in the formula gives us:
Finally we have to divide both sides by 15.
Therefore, the height of the trapezoid is 10 meters.
The answer for PA is 60/13. This is found by
The area of the rectangle is 60, therefore, the big triangle areas are 30 each. We know that the hypotenuse is 13, so therefore, we get
1/2(13*PA) = 30. This then simplifies to
13 * PA = 60, which then turns into
PA = 60/13.
Hope this helps and have a nice day:)
Do you want the exact form or decimal form?
Answer:
<u>9 workers finished the repairs, therefore 9 members of the original crew were removed. </u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Original crew scheduled to finish repairing a highway = 18 person
Number of days remaining to finish the work = 10 - 4 = 6 days
Number of days that the rest of the crew finished the repairs = 12 days
2. How many workers were removed from the crew?
We will use Inverse Rule of Three to answer this question because the less workers the crew has the more time it will take them to finish the repairs, as follows:
Workers Days
18 6
x 12
12x = 18 * 6 (Inverse Rule)
12x = 108
x = 108/12
x = 9
<u>9 workers finished the repairs, therefore 9 members of the original crew were removed. </u>
