slips of paper numbered 1 to 50 are placed in a hat. of a person picks a slip of paper out of the hat, what is the probability they the number on the slip ends in 4?

Step-by-step explanation:

Since we have given that

Value of 2s in 55,220

As we have seen that there are two 2 s , one is in hundreds position and other is in tens .

Value of 2 which is in hundreds position = 200

Value of 2 which is in tens position = 20

On Comparing , we get the difference given by

Similarly,

There are two 5s , one is in thousands position and other is in thousands.

Value of 5 which is in  thousands position = 50000

Value of 5 which is in hundreds position = 5000

On comparing , we get the difference is given by

Final answer:

Jay spent 36 minutes talking with his friends on Saturday after spending 2/5 of his time playing games and 1/2 of his time studying.

Explanation:

The total time Jay spent on all activities is 6 hours. He spent 2/5 of his time gaming, so that would be 0.4 * 6 hours = 2.4 hours, and he spent half of his time studying, that's 0.5 * 6 hours = 3 hours. To figure out how much time he spent talking with friends, we subtract the time spent gaming and studying from the total time. So, 6 hours – 2.4 hours – 3 hours = 0.6 hour. As there are 60 minutes in an hour, Jay spent 0.6 * 60 = 36 minutes talking with his friends.

The length of Line BC is 10

What is a triangle?

A figure bounded by 3 sides and all the internal angles add up to 180 ° is called a triangle.

What are similar triangles?

Triangles having the same corresponding angles measures and proportional side lengths are called similar triangles.

How to find the length of the line BC?

Considering Δ AXY    and    ΔABC

                      ∠AXY       =      ∠ACB  (corresponding angles are equal)

                       ∠AYX       =      ∠ABC   (corresponding angles are equal)

                       ∠A is common in both the triangles

∴ We can say the triangles are similar .

Now, let H be the height of ΔABC and h be the height of ΔAYX

So, we can say,  

• Now, we know that area of the triangle can be found with the help of the formula (1/2)x(base)x(height)

So,  

⇒    

Now, substituting XY = 5 and    in the above equation, we get

⇒ BC² = 100

⇒ BC = ± 10

Since BC is the length , so it cannot be negative.

So, the negative value is rejected.

∴  BC = 10

Option B is correct.
