If it is 10;25 p.m. what time was it 11 hours and 55 minutes before that?

Answers

Answer 1

Answer:

Answer:

10:30 am

Step-by-step explanation:

First we must convert the 10:25 pm to the 24 hour clock so we wont have negative results. To do this we add 12 hours to the given time (because it is between 1 pm and 11:59 pm)

10:25 hours+12 hours=22:25 hours

to this 22:25 hours we will substract 11:55 minutes to know what time was before that time passed like this:

-First we substract the minutes:

25-55=-30

we obtain a negative result, when this happens we add 60 to the first value (25)

85-55=30 (Minutes)

and substract 1 from the first value of the hours so we wont have 22 but 21. And we substract normally now having the minutes ready

21-11=10( Hours)

The time was 10:30 am

Answer 2

Answer: If it is 10;25 p.m. what time was it 11 hours and 55 minutes before 10:30 a.m.1

What is 4 3/4 + 7/8 showing all work

Answers

$4 (3)/(4) + (7)/(8)$

Convert mixed numbers to improper fractions

$= (19)/(4) + (7)/(8)$

Find de LCD for 4 and 8 :

Factor each denominator into its primes:

$4 = 2^2$

$8 = 2^3$

Find the least common denominator $2^3 = 8$

Adjust fractions based on the LCD :

$(19*2)/(8) + (7)/(8)$

Since the denominators are equal , combine the fractions:

$(2*19+7)/(8)$

$(38+7)/(8)$

$= (45)/(8)$

Therefore:

Convert improper fractions to mixed numbers

$= 5 (5)/(8)$

Write an algebraic expression for 15 decreased by twice a number

Answers

15-2x= that would be the algebraic equation. Remember that decrease usually means minus. A number is always represented by a variable, and then anything that by is usually a multiplication or division depending on how its stated.

An algebraic expression is, obviously, an expression with a variable.

"A number" would represent a variable, which, in this case, we'll use y.

So, 15 decreased by twice x.
15 - y x 2 =

Bella pays 7 payments of $5 each to a game store. She returns none game and receives $20 back. What is the change to the amount of money she has.

Answers

Answer:

Bella has $15 less

Step-by-step explanation:

Bella made 7 payments of $5 each. So, total payment made by her was $7*$5 = $35$ . As such, Bella had $35 initially. She played all games and received $20 back. This means that she lost $ 15 that is $35 - $20 = $15, in the game.

Therefore, she now has $15 less than the amount of $35 that she had initially. So, $15 is the the change to the amount she has now.

15$7 payments of 5$ = 35$ if she only gets 20$ back she lost 15$

Mrs. Ferguson looked at another hotel. She waited a week before she decided to book nights at that hotel, and now the prices have increased. The original price was $1589. The price for the same room and same number of nights is now $2075. What is the percent increase? Round to the nearest percent. Show your work. Will you plaes explain this ?

Answers

To calculate the percentage increase: First: work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100. If your answer is a negative number then this is a percentage decrease.

2075-1589=486

486*100/1589=30.58%

Rounding it we get,
30.6%
=31%
