Answer:
D. 2
Step-by-step explanation:
Each dial has a possible 10 numbers.
To find the total combinations, multiply teach dial by the number of possibilities by each other:
10 x 10 x 10 = 1,000 combinations.
Answer:
x = 21.6
Step-by-step explanation:
<u>Solution by Cross Multiplication</u>
For the equation
35=x36
The cross product is
3×36=5×x
Solving for x
x=3×365
and reducing
x=21.6
<u>Solution by Proportion</u>
Since the equation is an equality
If
36 ÷ 5 = 7.2
Then it is true that
x ÷ 3 = 7.2
Solving for x
x = 3 × 7.2
x = 21.6
