Answer:

The value of x = 513

Step-by-step explanation:

Let x, y, and z be the three numbers

Given

[tex]x+y+z=855[/tex]

Assuming x be the number which is 50% more than the sum of the other two numbers.

i.e.

(150)% of (y+z) = 1.5(y+z)

                y + z = x/1.5

As we know that

[tex]x + y + z = 855[/tex]

substituting y + z = x / 1.5 in the equation

[tex]x+\frac{x}{1.5}=855[/tex]

Multiply both sides by 1.5

[tex]x\cdot \:1.5+\frac{x}{1.5}\cdot \:1.5=855\cdot \:1.5[/tex]

[tex]1.5x+x=1282.5[/tex]

[tex]2.5x=1282.5[/tex]

Divide both sides by 2.5

[tex]\frac{2.5x}{2.5}=\frac{1282.5}{2.5}[/tex]

[tex]x = 513[/tex]

Therefore, the value of x = 513

[tex]2x - 11 = k[/tex]

Add sides 11

[tex]2x - 11 + 11 = k + 11[/tex]

Simplification

[tex]2x = k + 11[/tex]

Divide sides by 2

[tex] \frac{2}{2} x = \frac{k + 11}{2} \\ [/tex]

[tex]x = \frac{k + 11}{2} \\ [/tex]

Answer: x = 174, and x < 174.

Let the number be x.

Then 1/3 of the number = 1/3*x

1/3*x is decreased by 36 is the same as 1/3*x - 36

If 1/3*x - 36 is at most 22, we can write:

1/3*x - 36 is less than or equal to 22.

Therefore,

1/3*x - 36 <= 22

1/3*x - 36 = 22 (i), and 1/3*x - 36 < 22 (ii)

From (i):

1/3*x = 22 + 36 = 58, or x = 58 * 3 = 174.

From (ii):

1/3*x < 22 + 36 = 58, or x < 58 * 3 , or x < 174.

Therefore,

x = 174, and x < 174.

Answer:

Conservation of momentum means that the final momentum must be the same as the initial momentum, where the momentum is defined as:

P = m*v

where m is mass, and v is velocity.

First, let's calculate Pi, the initial momentum.

Pi = Pi₁ + Pi₂

Where the subscripts 1 and 2 refer to each puck:

Pi₁ = 0.17kg*15m/s = 2.55 (kg*m/s)

Pi₂ = 0.11kg*0m/s = 0 (kg*m/s)

Pi = 2.55 (kg*m/s) + 0 (kg*m/s) = 2.55 (kg*m/s)

Now, after the collision we have that:

The first puck comes to rest, then:

Pf₁ = 0.17kg*0m/s =  0 (kg*m/s)

And the second puck will have a velocity v, that we want to find:

Pf₂ = 0.11kg*v

Pf = Pf₁ + Pf₂ = 0 (kg*m/s) +  0.11kg*v =  0.11kg*v

And by conservation of momentum we have:

Pi = Pf

2.55 (kg*m/s) = 0.11kg*v

We divide in both sides by 0.11kg

2.55 (kg*m/s)/0.11kg = v

23.2 m/s = v

And from this, the final momentum will be the same as the initial:

Pf = 23.2m/s*0.11kg = 2.55 (kg*m/s)

The total final momentum of the system is 2.55 Kg m/sec and this can be determined by conserving the momentum.

Given :

A hockey puck with a mass of 0.17 kg is traveling to the right along the ice at 15 m/s it strikes a second hockey puck with a mass of 0.11 kg the first hockey puck comes to rest after the collision of conservation of momentum holds.

The formula of the momentum is given below:

P = mv

Now, let conserve the moment, that is:

[tex]\rm P_i=P_f[/tex]   --- (1)

where [tex]\rm P_i[/tex] is the initial momentum and [tex]\rm P_f[/tex] is the final momentum.

First, determine the initial momentum.

[tex]\rm P_i = 0.17\times 15 + 0.11\times 0= 2.55\;Kg\;m/sec[/tex]

Now, determine the final momentum.

[tex]\rm P_f = 0.17\times 0+ 0.11\times v = 0.11v\;Kg\;m/sec[/tex]

Now. substitute the value of [tex]\rm P_i[/tex] and [tex]\rm P_f[/tex] in the equation (1).

[tex]\rm 2.55=0.11v[/tex]

v = 23.18 m/sec

So, the final momentum can be calculated as:

[tex]\rm P = 23.18 \times 0.11[/tex]

P = 2.55 Kg m/sec

Answer:

The elevation of the rest stop is 37.5 feet above sea level.

Step-by-step explanation:

Given that the elevation at the top of the hill is 127 feet above sea level and The valley floor is 52 feet below sea level.

So, the total length from the top of the hill to the valley floor

[tex]l= 127+52 = 179[/tex] feet

So, length of halfway [tex]= l/2=179/2=89.5[/tex] feet ...(i)

Assuming that the stop for rest, the halfway between the top of the hill and the valley floor, is at x feet above sea level.

So, the length between the stop position and the valley floor [tex]= 52 +x[/tex] feet.

As the stop position is at half-way, so by using equation (i), we have,

[tex]52 + x = 89.5 \\\\\Rightarrow x =89.5-52 \\\\[/tex]

[tex]\Rightarrow x=37.5[/tex] feet

Hence, the elevation of the rest stop is 37.5 feet above sea level.
