Answer 1

Answer: The first step we can take to find the simplest form of this inequality is to subtract 3 from both sides

$(1)/(2)$ n + 3 < 5

$(1)/(2)$ n + 3 - 3 < 5 - 3

$(1)/(2)$ n < 2

So now we have a simpler version to work with.
To further simplify, we can divide both sides by $(1)/(2)$ . Dividing by fractions is hard though, so smart people have found out that dividing by a fraction is the same as multiplying by that same fraction's reciprocal.

$(1)/(2)$ n / $(1)/(2)$ < 2 / $(1)/(2)$

$(1)/(2)$ n * 2 < 2 * 2

Now, we can work it out to find the completely simplified inequality, which would simply be

n < 4

The character '<' represents that the number being represented by the variable is less than the number that follows that character. On a proper number line, this is represented by an open circle above the number on the right of the inequality with an arrow pointing the same direction on the number line that the point of the inequality symbol is facing.
If that doesn't make sense, imagine the inequality symbol as the head of an arrow.

<====<<

So the arrow would be pointing to the left, with an open circle above the 4. The only choice listed that represents this is the second option down.
Option B is your correct answer choice.
Hope that helped! =)

Answer:

$(240)/(4) =60$

$(1800)/(3) =600$

Step-by-step explanation:

1. The result should by a 2 digit number.

So, I fix a two digit number first, say 60.

Then, I multiplied it by some random integer, say 4 and got 240.

Now, 240 is my dividend and 4 is my divisor.

My division problem is:

$(240)/(4) =60$

2. The result should be a 3 digit number.

So, I fix a three digit number first, say 600.

Then, I multiplied it by some random integer, say 3 and got 1800.

Now, 1800 is my dividend and 3 is my divisor.

My division problem is:

$(1800)/(3) =600$

1. 150 divided by 5= 30
2. 1,000 divided by 10= 100

Martina hits a volleyball ball upward with an initial velocity of 13 meters/sec. When she hits the ball, it is one meter above the ground. How long will it take the ball to hit the ground?

Answers

the ball will take 6.5 seconds to hit the ground

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.

A plane takes off at 6:00 am, traveling north at 270 miles per hour. A jet takes off at 7:00 am, traveling north at 460 miles per hour. At what time will the jet overtake the plane? (Round your answer to the nearest minute.)

Answers

Answer:

The jet will overtake the plane at 8:25 am.

Step-by-step explanation:

The distance $D_p$ traveled by the plane after time $t$ since it took off is modeled by the equation

$D_p = 270t$

And the distance $D_j$ traveled by the jet after time $t$ since the plane took off is given modeled by the equation

$D_j =460t-460$ (we set this up such that at $t=1,$ $D_j= 0$ )

Now, the jet will overtake the plane when $D_j> D_p$ :

$460t-460> 270t$

$460t-270t> 460$

$190t>460$

$\boxed{t> 2.42\: hours }$

Which is 2 hours and 25 minutes after 6:00 am, or at 8: 25 am; therefore, the jet will overtake the plane at 8:25 am.

Answer:

the answer is 8:25
