Answer:
Substitute the known values into the formula: 140 = 7(w)(5).
Solve for the unknown: w = 4 m.
Check:
140 = 7(w)(5) => w = 140/(5 x 7) = 140/35 = 4. => Correct.
Substitute the known values into the formula:
7 = 140(w)(5).
Solve for the unknown: w = 7 m.
Check:
7 = 140(w)(5) => w = 7/(140 x 5) = 7/700 = 1/100. => Incorrect.
Substitute the known values into the formula:
5 = 7(w)(140).
Solve for the unknown: w = 2 m.
Check: 5 = 7(w)(140) => w = 5/(7 x 140) = 5/840 = 1/168. => Incorrect.
Hope this helps!

Let EB and CF be two heights. Then quadrilateral EBCF is rectangle, so BC=EF=5 m. It is given that bases are BC=5 m and AD=11 m. Triangles ABE and DCF are congruent, thus,
Consider right triangle ABE, by the Pythagorean theorem

Answer:
649.32
Step-by-step explanation:
Answer:
the "acceleration" is -15m/s (it's negative because it is slowing down, not speeding up[it might just be a positive 15m/s if it is called deceleration and not acceleration])
Step-by-step explanation:
30m/s (starting speed)/2 (the number of seconds it took to stop from 30m/s
