I totally understand how they can be frustrating. Try drawing it out as a picture. Draw a straight horizontal line to show where surface of the pool is at. This line is considered to be at 0 meters. Since the swimmer is measured to be 2.3 meters tall with their arms stretched up, and the diving board they are on is 10 meters high, their maximum height is 10m+2.3m which is 12.3m. The depth of the pool, since the surface of the pool is 0m, would be -5.5m (don't forget to always include the unit of measurement, whether it's feet, meters, inches!). Since the diver goes from 12.3m to -5.5m, I would find how far they traveled by writing -5.5m-12.3m=-17.8m; that is, the driver traveled down 17.8 meters.
Answer:
Can't be determined
Explanation:It can't be determined since there are two sides that you need to find out.
The number of minutes that would make the water level be less than or equal to 64 cups is;
160 minutes.
We are given the equation;
W = -0.414t + 129.549
where;
t is the number of minutes
W is the level of water
The expression to find the amount of time it will take for the water level be less than or equal to 64 cups is;
-0.414t + 129.549 ≤ 64
Using substitution property of equality, subtract 129.549 from both sides to get;
-0.414t + 129.549 - 129.549 ≤ 64 - 129.549
-0.414t ≤ -65.549
Using division property of equality, divide both sides by -0.414 to get;
t ≤ -65.549/-0.414
t ≥ 158.33
(sign changed to ≥ because we divided the inequality by a negative number.)
We have to approximate the inequality to get;
t = 160 minutes.
