Answer:
2 hours.
Step-by-step explanation:
2 and a half hours is 2.5 hours.
30 minutes is 0.5 hours.
2.5 - 0.5 = 2 hours.
Answer:
2 hours (I know I'm late but I like to answer things TvT)
Step-by-step explanation:
2 hours can be converted into 120 minutes (60 mins in an hour, 60 x 2 = 120)
120 minutes plus the half hour (30 mins) equals 150 minutes.
150 minutes minus 30 minutes equals 120 minutes, so 2 hours is your answer.
The water level in an ocean changes at an average rate of 3 meters per hour. At this rate, how many hours would it take for the water level to change 12 meters?
Answer: 4 hours
Step-by-step explanation:
The water level changes at an average rate of 3 meters per hour.
The question wants to know how long it will take for the ocean water level to change 12 meters.
You can use direct proportion:

x hours : 12 meters
Cross multiply to get:
3x = 12
x = 12 / 3
= 4 hours

sales tax included.
Round your answer to the nearest cent, as necessary.

Next I rounded it.
55.349325 = 55.35
Lastly, I added 819.99 plus 55.35
819.99 + 55.35 = 875.34

If q varies directly as r, and q=20 when r=5, find the constant of variation.
a.k=2
b.k=3
c.k=4
d.k=5
Answer:
c. k=4
Step-by-step explanation:
5 in 4 places is 20 4 is a constant variation
The value of constant of variation k is 4.
Since, q varies directly as r.
[tex]q=kr[/tex]
Where k is constant of variation.
Substitute.[tex]q=20,r=5[/tex] in above equation
[tex]k=\frac{20}{5} =4[/tex]
Thus, The value of constant of variation k is 4.

It is the end of the semester, and the clubs at school
are recording their profits. The Science Club started out
with $20 and has increased its balance by an average
of $10 per week. The Math Club has saved $5 per
week after starting out with $50 at the beginning of the
semester.
al. Choose the equation below which represents the
balance the science club has. Let x represent the
number of weeks and y represent the balance of the
science club's account
y= 20 + 50x
y= 20 + 10x
y= 10 + 20x
y= 10 + 10x
y=50 + 5x
Y=5 + 10x
Answer:
y=20 + 10x
Step-by-step explanation:
Y=balance

A circular running track is 14 of a mile long. Elena runs on this track, completing each lap in 116 of an hour. What is Elena’s running speed? Include the unit of measure
Answer:
The wording is quite confusing, but here it goes
Step-by-step explanation:
T(track)= 14 of a mile. 1 mile is 5280 feet. If Elena is running each lap at 116 of an hour, (116%?) then 16% of 60 is 9.6 minutes, so each lap takes 69.6 minutes. One lap is 1312 feet, so 5280/1312= 4.02, so she can run 4 laps, which will take her 278 minutes. So 1312 is 24% of a mile, and she is running at .24 mph.
