The combination for opening a safe is a four-digit number made up of different digits. How many different comninations can you make, using only add digits?

Answers

Answer 1

There are 625 different 4-digit codes only made with odd numbers.

How many different combinations can you make?

To find the total number of combinations, we need to find the number of options for each one of the digits.

There are 4 digits, such that each digit can only be an odd number.

For the first digit, there are 5 options {1, 3, 5, 7, 9}For the second digit, there are 5 options {1, 3, 5, 7, 9}For the third digit, there are 5 options {1, 3, 5, 7, 9}For the fourth digit, there are 5 options {1, 3, 5, 7, 9}

The total number of different combinations is given by the product between the numbers of options, so we have:

C = 5*5*5*5 = 625.

There are 625 different 4-digit codes only made with odd numbers.

Answers

Answer:

135 degrees

Step-by-step explanation:

(8x-7)+(12x+57)=180

combine like terms

20x+50 = 180

subtract 50 on both sides

20x = 130

divide by 20

x = 130/20

x = 13/2

x = 6.5

cpq = 12x+57

cpq = 78 + 57

cpq = 135

Given that he took a nap everyday, last summer We have that .

For the month of July,

he had 31 naps( 31 days are in July)

Number of snores he made =31 x 320=9,920 snores

For the month of August

he also took 31 naps ( 31 days are in AugusT)

Number of snores he made = 31 x 320=9,920 snores

If h(x) = x3 + x and g(x) = 2x +3, then g(h(2))

Answers

Answer:

They both equal 23 so it’s a true statement

Step-by-step explanation:

h(x) = x3 + x and g(x)

h(2) = 2^3 + 2

= 8 + 2

= 10

g(h(2))

= g(10)

= 2*10 + 3

= 20 + 3

= 23

2x +3, then g(h(2))

h(2) = 2^3 + 2 = 8+2 = 10

Now we will substitute into g(h(2)

g(h(2)) = g(10)

Now we will substitute into g(x).

g(10) = 2*10 + 3 = 23

g(h(2)) = 23

They are both equal 22 so it’s equal
