Answer:
Step-by-step explanation:
You have the following information given in the problem:
- She works as a tutor for $8 an hour and a waitress for $9 an hour.
- The total hours she worked at her two jobs is 100 hours.
Therefore, have:
(
is the total of hours she worked at his job as a waitress)
(
is the total dollar amount she earned this month)
Substitute into the
and simplify. Then, the expression asked is:

Distance walked by Laura to reach school each day = 3/5 mile
Distance walked by Isaiah to reach school is 3 times that of Laura and it is already given in the question.
Then
The distance walked by Isaiah to reach school each day = (3/5) * 3
= 9/5
= 1 4/5
So Isaiah walks a distance of 1 4/5 miles each day for reaching school. I hope that the procedure of doing such problems is clear to you and yiou can attempt such problems in future without needing any help.
Isaiah's walk: 3 times as long as Laura's
Laura's walk: 3/5 mile
3 * 3/5 mile = 9/5 mile = 1 4/5 mile
The correct result would be 1 4/5 mile.

Final answer:
The question from the student is about time airborne for a volleyball hit upwards with an initial velocity. A physics equation of motion is utilized to solve it by inserting the values and extracting time.
Explanation:
The subject of the question is physics, specifically the subtopic of kinematics in terms of upward motion. The problem can be solved by using the equation of motion: `y = y0 + v0 * t - 0.5 * g * t²`, where y0 is the initial height, v0 is initial velocity, g is the acceleration due to gravity and t is the time taken. In this situation:
- y0 is 1 meter (the starting height of the ball).
- v0 is 13 m/s (the initial upward velocity of the ball).
- g is approximately 9.8 m/s² (the acceleration due to gravity).
Set y (the final position) to 0 (ground level), and solve for t (time taken):
0 = 1m + (13 m/s) * t - 0.5 * (9.8 m/s²) * t²
Solving this quadratic equation, we get two solutions as the time cannot be negative for this context, so choose the positive value as the time taken for the ball to hit the ground. This will give the duration the volleyball remains in the air after being hit by Martina.

50
Step-by-step explanation:
When you around to the nearest ten, you look at the ones digit, which in this case, is 8. Since that is 5 and above, you would have to round the 4 in the tens digit up to 5, resulting in 50.
