The Large Hadron Collider is a tube formed into a circular loop measuring 4.3 km in diameter. It is used by physicists to accele

12345 [234]

Answer:

9005.90 m

Step-by-step explanation:

The radius of the collider is half the diameter or 2150 m. The arc length S subtended by the angle is given by

S = r×(theta) where theta is the angle in radians. We need to convert the degree angle into radian angle using the following:

240° × (2pi/360°) = 4.19 radians

Therefore, the distance traveled by the atoms is so equal to the arc length S so

S = (2150 m)×(4.19 rad) = 9005.90 m

Adam has 10 blocks numbered 1 through 10. Which describes the probability of randomly choosing a block that has an even number?

Licemer1 [7]

Answer:

$\dfrac{1}{2}$

Step-by-step explanation:

Given that:

10 number of blocks which have numbers from 1 through 10.

To find:

Probability of randomly choosing a block that has an even number.

Solution:

The given set of numbers is: {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

There are a total of 5 Even numbers are {2, 4, 6, 8, 10}.

And There are a total of 5 Odd number are {1, 3, 5, 7, 9}.

Formula for probability of an event <em>E</em> can be observed as:

$P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}$

Here, Event <em>E </em>is randomly choosing an even number.

Number of favorable cases = 5

Total number of cases = 10

Therefore, the required probability is:

$P(E) = \dfrac{5}{10}\\\Rightarrow P(E) = \dfrac{1}{2}$

I’m confused on this one

Anvisha [2.4K]

The triangles are similar. Set the two triangle's measurements equal to each other

8/10 = (x - 1)/(x + 2)

Cross multiply

8(x+ 2) = 10(x - 1)

Distribute the numbers

8(x) = 8x

8(2) = 16

10(x) = 10x

10(-1) = -10

8x + 16 = 10x - 10

Isolate the x. Subtract 16 from both sides, and 10x from both sides

8x (-10x) + 16 (-16) = 10x (-10x) - 10 (-16)

8x - 10x = -10 - 16

Simplify. Combine like terms

-2x = -26

Isolate the x. Divide -2 from both sides

-2x/-2 = -26/-2

x = -26/-2

x = 13

13 is your answer for x

hope this helps
