Answer:
20 games
Step-by-step explanation:
- 60% is the same as
.
- Divide 12 games by 3 to get one fifth of the total games instead of three fifths of the total games. One fifth of the total games is four games.
- Now multiply the 4 games by 5 to get five fifths of the total games, or all of them.

a=
a=20
b=16
Answer:
Read below.
Step-by-step explanation:
A=l*w
320=l*(4/5)l
320=(4/5)(l2)
(5/4)(320)=(5/4)(4/5)(l2)
5(80)=l2 (320/4=80)
400=l2
√400=√l2
20=l
w=(4/5)(20)
w=4*4 (20/5=4)
w=16
length=20 feet
width=16 feet
If you don't understand square roots, maybe you understand prime factorization.
320=2*2*2*2*2*2*5=(2*2*2*2)*(2*2*5)=16*20 and 16 is 4/5 of 20
If you don't understand prime factorization you can use trial and error.
2*160
4*80
5*64
8*40
10*32
16*20 answer, because 16 is 4/5 or 0.8 times 20

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

The inequality ∣60∣≤∣−60∣ holds true. This is because the absolute value of both 60 and -60 is equal to 60.
The expression ∣60∣≤∣−60∣ can be evaluated by calculating the absolute values on both sides. The absolute value of 60 is 60, and the absolute value of -60 is also 60. So, ∣60∣=∣−60∣=60.
Since 60 is equal to 60, the inequality ∣60∣≤∣−60∣ is true. This inequality states that the absolute value of 60 is less than or equal to the absolute value of -60. In this case, since both absolute values are equal, the statement is true. The absolute value function essentially removes the negative sign from a negative number, making it positive, and in this case, the absolute values of 60 and -60 are indeed the same, resulting in a true inequality.
