When lines cross each other in a triangle from a point to the mid point of the opposite side as shown, AV  is 2 times as long as VF

To solve for X we would have AV = 2*VF

The equation becomes:

3x+6 = 2(x+6)
 
Now we solve for X

3x+6 = 2(x+6)

Distribute the 2 on the right side:

3x + 6 = 2x +12

Subtract 2x from each side:

X +6 = 12

Subtract 6 from each side:

x = 6


 Now if you needed to solve the length of AV or VF, you replace x with 6 and solve.

Belle bought 18 seeds in order to plant an herb garden for her grandma. Of the seeds she bought, 10 were parsley seeds.
Harrizon [31]

Answer:

  0.3431

Step-by-step explanation:

Here, it can work well to consider the seeds from the group of 18 that are NOT selected to be part of the group of 15 that are planted.

There are 18C3 = 816 ways to choose 3 seeds from 18 NOT to plant.

We are interested in the number of ways exactly one of the 10 parsley seeds can be chosen NOT to plant. For each of the 10C1 = 10 ways we can ignore exactly 1 parsley seed, there are also 8C2 = 28 ways to ignore two non-parsley seeds from the 8 that are non-parsley seeds.

That is, there are 10×28 = 280 ways to choose to ignore 1 parsley seed and 2 non-parsley seeds.

So, the probability of interest is 280/816 ≈ 0.3431.

___

The notation nCk is used to represent the expression n!/(k!(n-k)!), the number of ways k objects can be chosen from a group of n. It can be pronounced "n choose k".

The processing speed of a certain computer is 10¹¹ instructions per second. Another computer has a processing speed that is 10³
Mashcka [7]
“Times as fast” means you need to multiply the original speed (10^11) by how many times faster the faster processor works:

10^11 instructions/second • 10^3 faster = 10^14 instructions/second

The key is “___ times as fast”.
