You are correct, Baneofwizard

(1 + 5/6)  - (-1/6)  =

1 + 5/6 + 1/6  =

1 + 1  =

2

Area = (1/2)r^2(theta)  where r  is the radius and theta is the radian measure of the sector's arc

C = 2*pi*r

C = 2*pi*(12 cm)  = 24pi cm = about 75.4 cm  in one revolution

The answer is 1 trillion 81 billion 44million and the rest dosnt fit on my calculator next time use one 

Find the circumference of the wheel, that's how far the wagon will go if the wheel makes one rotation.

1 - What is Rc ? is this the shear force ?? 

In the free-body diagram for CD, R_C is the net force on CD due to AC (i.e. AC is helping to support CD and keep it from going down).

In the free-body diagram for AC, R_C is the reaction of CD on AC (Newton's 3rd law of motion).

2- Is RE is the reaction of the support in beam BE ? 

Yes, in free-body diagram BE, R_E is the force of the support at E on BE.  

3- What is RB in the beam BE ? 

In free-body diagram BE, R_B is the force of AC on BE (i.e. AC is trying to pull BE down).

In free-body diagram AC, R_B is the reaction force of BE on AC (i.e. BE is trying to keep AC up - Newton's 3rd law again).

Hope this helps.

Thank you!!!

Wouldn't that be 2? Since your taking away negative 1 so technically adding one if I'm wrong plz correct me 

2/3h - 1/3h + 11=8     combine like terms on the left

(1/3)h + 11  = 8      subtract 11 from both sides

(1/3 )h  = -3      multiply both sides by 3

h = -9

-9/10 / 6 = -9/10 * 1/6 = -9/60

sqrt(54)  = sqrt(9 * 6)  =  sqrt(9) *sqrt(6)   = 3*sqrt(6)

-12 = -24 + k  add 24 to both sides

12  = k

A ski resort charges $80 for adult all-day passes and $35 for children's all-day passes. On a particular day, they made $55,750 in sales. They also know that they sold 761 passes altogether. How many of each ticket did they sell?

We have this system of equations

x + y = 761

80x + 35y  = 55750      

Where x is the number of adult tickets and y is the number of children's  tickets

Using the first equation, we can arrange it as   y = 761 - x

And substituting this into the second equation for y, we have

80x  + 35(761 - x)  = 55750    simplify

80x + 26635 - 35x = 55750

45x = 29115    divide both sides by 45

x = 647   and this is the number of adult tickets sold

And y = 761 - 647  = 114 = children's tickets sold

Using

v_f²  = v_i²  + 2ad

Where

v_f = final velocity 

vi = 0

a = (-9.8)m/s^2

d = 20m

So we have

0²  = v_f²  + 2(-9.8)(20)

v_f² = 392m²/s²       take the negative square root of both sides

v_f = about -19.8m/s   [ and this will be negative since the motion is downward]

2+2=4

tan(60) = sqrt(3) / 1

9 X 9=81

You divide total distance travelled by time(or the number of hours, days......etc.)

!!Its what you make of it!!

The correct answer is= -210

what is 255^4=4,228,250,625

262

\(2e^6 * 9e^{-4} =18e^{(6+-4)} =18e^2 \)

21!!!!!!!!!!!!!!!!!!!!!!!!!!!
