Plzzz help mea cylinder has a radius of 13 cm and a height of 22 cm what is its surface area?

Answer:

Step-by-step explanation:

The ways we can get "1 counter to be white out of 2 draws" is:

1. If 1st one taken out is white and next one different color, and

2. If 2nd one taken out is white and 1st one different color

In probability, AND means MULTIPLY and OR means ADD

Here, we are actually looking for ways of 1st one white, next one different OR first one different and next one white. Let's find them separately.

1. If 1st one taken out is white and next one different color

there are 6 white and 10 total, so 1st one white is 6/10

not replaced, so now there are 9 total and 4 of them are different,so different probabililty is 4/9

We multiply these two to get:  6/10 * 4/9 = 4/15

2. If 2nd one taken out is white and 1st one different color

probabilty 1st one different color is 4/10 since 4 are different and we have total of 10

since not replaced, now we have 9 total and still 6 white.

probability of white in 2nd draw is 6/9

We multiply these two to get:  4/10 * 6/9 = 4/15

Now we add these 2 as stated earlier, so 4/15 + 4/ 15 = 8/15

Step-by-step explanation:

Answer:

The answer is 39.

Step-by-step explanation:

You have to substitute the value of x into the expression :

Answer:

39

Step-by-step explanation:

To solve your question we must replace x with the given number which is 9 so,

3 (9) +12 =

We can now solve it by multiplying 3 * 9 which will give us 27. Then we can add 27 to 12.

27 + 12 = 39

Hope this helps!!

Answer:

Larger number is 13 and Smaller number is 4.

Step-by-step explanation:

Let the larger number be x.

Also let the smaller number be y.

We need to find the two numbers.

Given:

The larger of two numbers is twice the smaller increased by five.

framing in equation form we get;

⇒equation 1

Also Given:

Three times the larger exceeds double the smaller by 31

⇒equation 2

Now Substituting the value of x from equation 1 in equation 2 we get;

Now Using Distributive property we get;

Combining the like terms we get;

Now Using Subtraction property we get;

Now Using Division property we get;

Now Substituting value of y in equation 1 we will find the value of x.

Hence Larger number is 13 and Smaller number is 4.
