Answer:

What do you want me to do? It is already solved

Step-by-step explanation:

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:

A) 13 i think

Step-by-step explanation:

832 , 208 , 52

The difference between 832 and 208 is 624 and then the difference between 208 and 52 is 156. If we check the relation between 624 and 156 which is 624/4 = 156 so then if we divide 156 by 4 we get 39 and then subtract 39 from 52 we get 13.

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:

10 and 1

Step-by-step explanation:

10+1=11 and the difference of 10-1 is 9

answer= 102

Step-by-step explanation:

Given,

Perimeter=46

Let, breadth=X

Then, length = 4X-7

Now,

Perimeter= 2(l+b)

46 = 2(4X-7+X)

46 = 2(5X-7)

(46)÷2 = 5X-7

23+7 = 5X

30 = 5X

30÷5 = X

:-X = 6

Also,

length = 4×6-7 = 17

breadth = 6

Then,

Dimensions = l×b

= 17×6

= 102

Answer:

Step-by-step explanation:

Let 'w' be the width

so the length = 4w - 7

The formula of the Perimeter is

Perimeter = 2(length + width)

         46   = 2(4w - 7+ w)

        46    = 2(5w- 7)

        46    = 10w-14

      46+14 = 10w

         60 = 10w

          w = 6

Add

[tex]x=-2[/tex]

[tex]y=9[/tex]

Step-by-step explanation:

To find the value of [tex]y[/tex], we can add the two equations:

[tex]2x+3y+(-2x+y)=23+13[/tex]

[tex]2x+3y-2x+y=36[/tex]

[tex]4y=36[/tex]

[tex]y=9[/tex]

To find for [tex]x[/tex], we can use substitution:

[tex]2x+3y=23[/tex]

[tex]2x+3(9)=23[/tex]

[tex]2x=-4[/tex]

[tex]x=-2[/tex]

∴ [tex]x=-2,y=9[/tex]

Step-by-step explanation:

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
