8 hours is 1/4 of the time the gym is open. 1/4 is a quarter. You need to times 8 by 4 which equals 32. The gym is open for 32 hours. Hope this helped
Answer:
-6 7/hr= -6F per hour
Step-by-step explanation:
a rate of change can be defined as:
R=(total change in some quantity) (time in which the change happened)
In this case we know that the temperature dropped -30F in a given time, then we already know that:
Total change in some quanity =-30F now we know that this change took place between the 1:00pm and the 7:00 pm the total amount of ime between these two hours is:
T= (7.00 - 1.00 hr)= 6.00 hr
this means that the change happened =6 hours.
then we can replace these values in the above equation to get:
R=(-30F)/(6hr)=-6F/hr
this means that for each hours that passes the temperature decreases 6F
we also can write that this rate as:
R=-6F/HR =-6F per hour.
Answer:
Number two: x > -9/2, x < 3/2
Number one: x is less than or equal to 3/4, x is greater than or equal to - 13/4
Step-by-step explanation:
Number one:
|4x+5| > 10-2
|4x+5| > 8
4x+5 > 8
-(4x+5) > 8
x > 3/4
x < -13/4
x > 3/4, x < -13/4
(all of these signs are greater than or equal to and less than or equal to)
Number two:
|2x+3| > -6
2x+3 > -6
-(2x+3) > -6
x > -9/2
x < 3/2
x> -9/2, x < 3/2
(all of these signs are correct and not greater than or equal to or less than or equal to)
Answer:
3/4
Step-by-step explanation:
13/10 - 1 = .3
1 - 3/4 = .25
.3 > .25
You want the smaller answer. 3/4
