Find the probability of rolling a 5 or greater

1 answer:

8 0

Well if this a standard dice than the chance of rolling a 5 is 1/6 but if it's 5 or greater it would be 2/6 or 1/3 because there is now 2 different numbers that we are looking for

Find r if 0=pi/6 rad sector 64m^2

kap26 [50]

Given:

Area of a sector = 64 m²

The central angle is $\theta=\dfrac{\pi}{6}$ .

To find:

The radius or the value of r.

Solution:

Area of a sector is:

$A=\dfrac{1}{2}r^2\theta$

Where, r is the radius of the circle and $\theta$ is the central angle of the sector in radian.

Putting $A=64,\theta=\dfrac{\pi}{6}$ , we get

$64=\dfrac{1}{2}r^2\times \dfrac{\pi}{6}$

$64=\dfrac{\pi}{12}r^2$

$64\times \dfrac{12}{\pi}=r^2$

$\dfrac{768}{\pi}=r^2$

Taking square root on both sides, we get

$\sqrt{\dfrac{768}{\pi}}=r$

$16\sqrt{\dfrac{3}{\pi}}=r$

Therefore, the value of r is $16\sqrt{\dfrac{3}{\pi}}$ m.

My problem is : P=2L+2W solve for L

natima [27]

Answer:
L = P/2 - W

Explanation:
Step 1 - Start by factoring out the two

P = 2L + 2W
P = 2(L + W)

Step 2 - Divide both sides of the equation by two

P = 2(L + W)
P/ 2 = 2(L + W)/ 2
P/ 2 = L + W

Step 3 - Subtract W from both sides of the equation

P/ 2 = L + W
P/ 2 - W = L + W - W
P/ 2 - W = L

The volume of a cone is 3 cubic units and its height is x units. Which expression represents the radius of the cone base, in uni

yKpoI14uk [10]

Cone Volume = (PI * radius^2 * height) / 3
3 = (PI * radius^2* x) / 3
radius^2 = 9 / (PI * x)
radius = square root (9 / (PI * x))
