The circular stone mound in Ireland called Newgrange has a diameter of 250 feet. A passage 62 feet long leads towards the center

alexgriva [62]

Answer:

Step-by-step explanation:

it's 125 for the radius and also 125-62 = 63

so 125+63 = 188

188 * 62 = X^2

11656 = X^2

107.96 = x

108.0 = x ( to the nearest tenth )

Two displacement vectors of magnitudes 21 cm and 79 cm are added. Which one of the following is the only possible choice for the

Ghella [55]

Here we want to find the possibles magnitudes of the sum of two vectors.

Sadly, the options are not given, so I will give you the range of all the possible magnitudes of the sum of these two vectors.

We will find that any magnitude in the range: 58cm ≤ M ≤ 100cm is a possible magnitude or the resultant vector.

How we can find that range?

What we need to do is find the maximum and minimum.

The minimum is the case where the two displacements are in opposite directions, in that case, the magnitude of the sum will be:

79cm - 21cm = 58cm

The maximum is when both displacements are in the same direction, thus we must add the displacements, then we have:

79cm + 21cm = 100cm

Thus, any magnitude in the range:

58cm ≤ M ≤ 100cm

Is a possible magnitude for the resultant vector.

Can someone pls help me on this I dont understand this

Zielflug [23.3K]

Answer:

3rd option

Step-by-step explanation:

The equation of a line in point- slope form is

y - y₁ = m(x - x₁)

where m is the slope and (x₁, y₁ ) a point on the line

Here m = - 2 and (x₁, y₁ ) = 4. - 6 ) , then

y - (- 6) = - 2(x - 4) , that is

y + 6 = - 2(x - 4)

In a bag, there are blue, red, and green jolly ranchers. If the probability of getting a blue is 2/9 and the probability of gett

andreyandreev [35.5K]

Answer:

The probability of getting a green jolly rancher is $\frac{4}{9}$ .

Step-by-step explanation:

We are given that in a bag, there are blue, red, and green jolly ranchers. The probability of getting a blue is 2/9 and the probability of getting a red is 1/3.

Let the Probability of getting a blue jolly rancher = P(B) = $\frac{2}{9}$

Probability of getting a red jolly rancher = P(R) = $\frac{1}{3}$

Probability of getting a green jolly rancher = P(G)

Now, as we know that the Sum of all probability cases of any event is 1.

That is, here the event is that the bag contains blue, red and green jolly ranchers. There is not any chance of getting a jolly ranches of color other than this which means;

Probability of getting blue rancher + Probability of getting red rancher + Probability of getting green rancher = 1

$\frac{2}{9}$ + $\frac{1}{3}$ + Probability of getting green rancher = 1

Probability of getting green rancher = $1 - \frac{2}{9} - \frac{1}{3}$ = $1-\frac{5}{9}$

= $\frac{4}{9}$

Therefore, probability of getting a green jolly rancher is $\frac{4}{9}$ .
