Answer:
7 minutes
Step-by-step explanation:
First, subtract 70 from 350.
350-70=280
Now, divide 280 by 40
280/40=7
It took Ms. Thelmas oven to heat up from 70 degrees to 350 degrees in 7 minutes.
60/7 = (56 + 4)/7 = 56/7 + 4/7 = 8 4/7
check the picture below.
now, we're assuming the trapezoid is an isosceles trapezoid, namely AD = BC, and therefore the triangles are twins.
incidentally, b is the height of the trapezoid and likewise is also the altitude or height of the concrete triangle.
so we can simply get the area o the trapezoid, notice the bottom base is a+185+a, and then get the area of the concrete triangle and subtract the triangle from the trapezoid, what's leftover is just the vegetation area.

so that's the area of the trapezoid, now let's get the area of the triangle.
