Mathematics

8 0

Answer:Angle A is equal to 113

Step-by-step explanation:

If two angles are vertical, that would make them equal to each other.

7x-20=6x-1

Add on to both sides

7x-19=6x

Subtract Seven from both sides

-19=-x

Divide by negative one to get rid of the negative

19=x

Then plug x into the equation 7(19)-20

If x metres of string are cut from a piece y metres long how much is left?
Karolina [17]

Answer: The new length is: (y - x) metres.

Step-by-step explanation:

If we have a piece of string that is y metres long, and we cut x metres of strings from it, then the new length of the string will be equal to the difference between the initial length and the amount that we cut off.

So the initial length is y metres.

We cut x metres.

The new length is: (y - x) metres.

How many passwords of 4 digits are there(a)if none of the digits can be repeated?(b)start with 5 and end in an even digit?
liraira [26]

Answer:

5040,56

Step-by-step explanation:

We have to construct pass words of 4 digits

a) None of the digits can be repeated

We have total digits as 0 to 9.

4 digits can be selected form these 10 in 10P4 ways (since order matters in numbers)

No of passwords = 10P4

= 10(9)(8)(7)\\=5040

b) start with 5 and end in even digit

Here we restrain the choices by putting conditions

I digit is compulsorily 5 and hence only one way

Last digit can be any one of 0,2,4,6,8 hence 5 ways

Once first and last selected remaining 2 digits can be selected from remaining 8 digits in 8P2 ways (order counts here)

=56
