Latasha is getting married. she is inviting 300 people and is sending formal invitations to her wedding. if it takes her 90(or 1.5 minutes) to stuff and address each envelope, how much time will it take to complete her invitations? the answer must be in hours and minutes

it will take 7 hours and 30 minutes to complete her invitations

Step-by-step explanation:

time taken for one envelope= 90 secs

time taken for 300 envelopes= 90*300= 27000 secs

Converting it into minutes = 27000/60= 450 minutes

Converting 450 minutes to hours = 450/60= 7.5 hours

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.

the answer is 11.2 (i know i’m late)
