Byron bought a keyless entry door lock that has the digits 0 through 9 on the keypad. he wants to choose a three-digit entry code. how many different combinations are possible, if the digits can be repeated?
27
30
729
1,000'

The answer is 1,000! For each digit you get 10 options: 0,1,2,3,4,5,6,7,8,9.

So if you were to have ten options for each of the three digits you can enter, you multiply all possibilities together. So 10 times 10 is 100. 100 times ten is 1,000.

(10 x 10 x 10 = 1000)

the answer is 1,000

Step-by-step explanation:

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
