Answer:
He has been diving for 17 minutes
Step-by-step explanation:
* <em>Lets explain how to solve the problem</em>
- Paul is diving and is 3.5 feet below sea level
- He is descending at a rate of 0.5 feet per minute
- Paul is now at 12 feet
∵ His initial position is at 3.5 feet below the sea
∵ He is descending, that means he is moving down
∵ His final position is at 12
∴ <em>He is descending a distance = 12 - 3.5 = 8.5 feet</em>
∵ He is descending at a rate of 0.5 feet per minute
∵ He is descending 8.5 feet
∵ <em>Time = distance ÷ rate</em>
∴ <em>His time of descending = 8.5 ÷ 0.5 = 17 minutes</em>
* <em>He has been diving for 17 minutes</em>
Answer:
-5
Step-by-step explanation:
you have to look at the y axis
The locus means the “set of all” so the locus off points where x = y is all points where the x and y coordinate are the same.
One example is (1,1). Another is (2,2). Here the point (x,y) has the same number for x as for y. If you plot a few points (1,1), (2,2), (3,3) you will see they all fall on the same line. It is a diagonal line with positive slope that divides the first and third quadrants exactly in half.
For x=3 we find points where the first number (the x coordinate) is 3. The second number can be anything. Some points are (3,1) (3,2) (3,3). These points all lie on a vertical line that intersects the x axis at 3.
Answer:
<u><em>She got 18 correct</em></u>
How to do this:
25 x 25 = 6.25 if she got it correct
20 x 25 = 5.00 - 10 - 10 -10 -10 -10 = 4.50
18 x 25 = 4.50 - 10 -10 -10 -10 -10 -10-10 = 3.80
