How many 3 digit numbers can you make using these numbers: 4,2,9 (numbers can be reapeated)

Mathematics

bogdanovich [222]3 years ago
8 0

Answer:

You can make 27 different 3 digit numbers

Step-by-step explanation:

Since we can use 3 different numbers this means that each of the 3 digits can be one of the 3 numbers (4,2,9). This means that there are 3 different values for the first digit, 3 different values for the second digit, and 3 different values for the third digit, which mean that we can make 3 x 3 x 3 different 3 digit numbers (we took the number of possible values for each digit and multiplied them together.

3 x 3 x 3 = 27

Use the inverse variation equation to fill in the table.
Mandarinka [93]

The value of a is  0.10.

The value of b is 20.78.

The value of c is 0.02.

<h3>What are the missing values?</h3>

When two variables have inverse variation, the two variables move in opposite directions. If one variable increases, the other decreases.

p = 8.31 / V

V = 8.31 / p

a = 8.31 / 83.1 = 0.10

b = 8.31 / 0.4 = 20.78

c = 8.31 / 415.5 = 0.02

qaws [65]

Answer:

$15.679216

Step-by-step explanation:

new sp = 80% of cp

= 0.8 x 199.99

= 159.992

new sp2 = 120% of cp2

= 1.2 x 159.992

÷ 191.9904

new sp3 = 80% of cp3

= 0.8 x 191.9904

= 153.59232

new sp4 = 120% of cp4

= 1.2 x 153.59232

= 184.310784

difference = 199.99 - 184.310784

=15.679216
