Answer:
Step-by-step explanation:
We are given a ratio for this problem so we will use the formula for when we are given a ratio (as opposed to the formula for when you are given that the point you're looking for is a fraction of the way from one point to another, like 1/3 of the way from point A to point B. That's a different formula).
The formulas are for the x and y coordinates of the point in question:
and where
a = 3 (from the ratio),
b = 1 (from the ratio),
x1 = -4, y1 = 0 (from point J)
x2 = 0, y2 = 4 (from point K). Filling in for x first:
gives us
and now for y:
gives us
Therefore, the coordinates that partition that segment into the ratio of 3:1 are (-1, 3)
We are given the following equation:
Subtract both sides by 17
Take the positive/negative square root of both sides
This should be your answer. Let me know if you have any questions, thanks!
Brand b is 2 cents cheaper than brand a because it is 14 cents per ounce and brand a is 16 cents per ounce you do 1.68 divided by 12 and 1.28 divided by 8
<span>The answer is 10.536 inches per minute. There are 12 inches in a foot, so you would first multiply the number of feet by 12. 52.68 x 12 = 632.16 inches per hour. There are 60 minutes in an hour, so you would then divide the number of inches per hour by 60. 632.16 / 60 = 10.536 inches per minute.</span>
