Write an equation for the problem
25% of the production is 625. For an instance, p stands for the whole production of the day.
25% × p = 625
0.25 × p = 625
<em>This is the equation</em>
Solve for p and you'll find the production of the day
0.25 × p = 625
move 0.25 to the right side and it becomes the divisor
p =
p = 2,500
The cookies they plan on producing are 2,500 cookies

Answer:
Step-by-step explanation:
We have plane 1 flying SW for 4 hours at a rate of 415 mph. The distance he covers using the d = rt formula for distance, is 415(4) = 160 miles.
We also have plane 2 flying directly east (along the x-axis) for 4 hours at 327 mph. The distance he covers using the d = rt formula for distance, is 327(4) = 1308 miles. The angle in between them at this point is 135 degrees, and what we need to find is the length of the vector connecting the 2 planes. IF this was right triangle trig that distance would be the hypotenuse and we could solve for it using Pythagorean's Theorem. BUT it is NOT a right triangle, so we have to find some other means with which to solve for that length. We will use the Law of Cosines to do this.
which simplifies a bit to
If you add all of that together, you'll get
and you'll take the square root of that to get that the distance between the 2 planes after 4 hours is
2745 miles
