7/10 is bigger.

To reach this answer you take a common denominator by multiplying the given denominators with the opposite numerators.

7(14)= 98
9(10)=90

Thus 98 > 90.

502.65  = pi (r)^2 * 8   divide both sides by 8pi

502.65 / [8pi]  = r^2     take the square root of both sides

r ≈ 4.472 in

Hey, ND.....good to see you!!!

Here's my take on this one......

If the Celestial North Pole traces out a complete orbit every 26,000 years, it must move through 360°  during that time....so.....in one year it must move:

(1/26000) * 360°   =  (9/650)°  = about  0.01384615° =

about    0.8307 ' 50"  [roughly]

Just plug -4 in anywhere you see x, and solve.

The equation is as follows (with 4s plugged in):

7+7(-4)-(-2(-4))+3

Then, according to the order of operations, do multiplication first:

7+(-28)-(8)+3

Then do addition and subtraction starting from the left, and you're left with:

-26

as the final solution.

Thank you

Just use any calculator that has a reciprocal key (1/x). Example: 1/5. Just enter 5 and hit the 1/x key and you will get the decimal that you want.

I do it for a secret reason.

Ok, Let's start with the whole numbers. 2+2+1=5.  Remember that.

Let's make all of the denominators 8 now. 2/8 + 3/8 + 4/8= 9/8 or 1 1/8

5+1 1/8=6 1/8.

1. 4x/3-5=11    add 5 to both sides

4x/3  = 16       multiply both sides by 3

4x  = 48         divide both sides by 4

x = 12

 2. 2/5(3x+4)=6       multiply both sides by the reciprocal of 2/5   = 5/2

3x + 4   = 6(5/2)    simplify

3x + 4  = 30/2

3x + 4  = 15       subtract 4 from both sides

3x  = 11             divide both sides by 3

x = 11/3

3. 2(3x+4)=4x+12     distribute the 2 on the left side

6x + 8  = 4x + 12    subtract 4x, 8 from both sides

2x  = 4                  divide both sides by 2

x = 2

Thanks, rarinstraw......this could also be :

[3x+2] / 5=7          if so.....multiply both sides by 5

3x + 2  = 35        subtract 2 from both sides

3x  = 33               divide both sides by 3

x = 11

5 2/3

i dont understand how to solve these. 1. 4x/3-5=11  2. 2/5(3x+4)=6    3. 2(3x+4)=4x+12

This is a linear model....note that everytime x changes by 1, y changes by 4......and the slope of a line = change in y / change in  x   =  4 / 1   = 4

And using the point (1,6), we have

y - 6  = 4(x - 1)   simplify

y - 6  = 4x  - 4    add 6 to both sides

y = 4x + 2

Why do you ask so many of these questions like you are playing a braindead game?

You do not preface the questions. You can look a lot of these up anyway.

Now that you know the answer what are you going to do with it?

If you need advice I can tell you where to store it for when you need it. It is the same place it came from when you ask it.  :/

You might be user101 but most of us will not let you use us like we are your toy robots.

So this is the last of your questions I will answer unless you act like you give more than a damnn about  it.

I assume that you mean that angle Y  = 90°...if so, we have

cosZ  = 28/35     = 4/5      take the inverse cos

cos^-1 (4/5)  = Z  = about 36.87°

(6+[1/4])+(5+[5/12])+(2/3)

(6+[3/12])+(5+[5/12])+(8/12)

(6+5)+([3/12]+[5/12]+[8/12])

11+(16/12)

(11+1)+(4/12)

12+(4/12)

12+4/12=12+1/3→1/3→ln(100)/ln(10)=.3…→12+.3…=12.3…

it is 12.3… or 12 1/3

3x+2/5=7

     -2/5   -2/5

3x=6 + 3/5

 3      3

x=2 + 1/5

Sorry, User 101.....but  you have made a mistake after this step:

[2-3(-2)]²   

We evaluate the multiplication of -3 * -2  first, which gives us + 6  .....so we have....

[2 +6]^2   =

[8]^2  =

64

So... That was fun...

16/80=x/100

Let's make the problem a little bit smaller.

Let's divie both the top and bottom of 16/80 by 8. 

2/10=x/100

10 times what is 100? 10. 

20/100=x/100

Multiply by 100 on both sides and you get 20=x

That gives you the percent of dogs that are golden retrievers.

Therefore, 20% of the dogs are golden retrievers.

No, it's 4.

[2-3(3-5)]²

[2-3(-2)]²

[-1(-2)]²

[2]² or 2²

4

This is easy to do and it is very cool how it works.

Force here is what converts the kinetic energy to heat by friction and slows the puck

fu  = coefficient of Kinetic friction

g = is the acceleration of gravity

Fu*g = a.

So friction force on the puck is the acceleration of gravity times the coefficient of kinetic friction and the acceleration force is made negative here because it is slowing down the puck. .

Puck friction to negative acceleration

fu=0.05

g = -9.81m/s^2

so

a = 0.05 * -9.81m/s^2 = -0.4905 m/s^2

For the moving puck

Velocity = v = u + (a*t) | u=initial velocity

So

Time = t = (v-u)/a

Distance = d = t *(v + u)/2

So

Distance d= ((v-u)/a) * ((v+u)/2)

This becomes d = (v-u)(v+u)/2a

Plugging in the numbers

d= (0 - 5.3)(0 + 5.3)/(2*-0.49.5) =28.63 meters

This is very slippery ice.

No! It's cheating!
