For the first question, the answer is A. You take 90 and multiply it by 3, then you get the time that it takes for one worker to mow the large park.
For the second question, you take 50 = k/0.25. To find k, you would want to multiply both sides with 0.25 to cancel the 0.25 on k's side. 50 times 0.25 is 12.5. I think C is your answer although I'm not really confident.
Answer:
The area of trapezoid is 20 square centimeters
Step-by-step explanation:
Let
x -----> the length of rectangle
y ----> the height of rectangle
h ----> height of trapezoid
Applying the Trapezoid Mid-segment Theorem we have that
----> equation A
---->
----> equation B
Remember that
The area of rectangle is equal to

The area of trapezoid is equal to
-----> equation C
substitute equation A and equation B in equation C

The area of trapezoid is two times the area of rectangle
therefore
The area of trapezoid is 20 square centimeters

Answer:
M (0,2)
Step-by-step explanation:
The coordinates of the mid point of mid point of AB (X,Y)
X =Ax - 1/4 * (Ax + Bx) = 1/4 * (2 + 6) = 2 ... Ax and Bx at opposite side of 0
Y = 1/4 * (3 + 1) = 1 ....... Ay and By at opposite side of 0
M (0,2)
