Answer:
360
Step-by-step explanation:
Given
Digits: 0 to 5
Required
Number of 4 digit passcode that can be generated.
First, we need to get the number of usable digits.
Digits 0 to 5 = 0,1,2,3,4,5
Number of digits = 6
To make a 4 digit passcode;
The first digit can be taken from any of 6 digits
The second digit, any of the remaining 5 digits
The third digit, any of the remaining 4 digits
The fourth digit, any of the remaining 3 digits
Number of passcode = 6 * 5 * 4 * 3
Number of passcode = 360
Answer:
-3 1/8.
Step-by-step explanation:
−7/8 − 2 1/4
= -7/8 + -9/4
= -7/8 - 18/8
= -25/8
= -3 1/8.
18
First you want to change the 20% into a decimal which is .20
Next you want to multiply 90 by .20 because that will give you the answer for 20% of 90
90x.20=18
Hope that helps
