Answer:
600
Step-by-step explanation:
30 = 2 x <u>3</u> x 5
40 =<u>2 x 2 x 2</u> x 5
75 = <u>5 x 5</u> x 3
L.C.M =<u> 2 x 2 x 2</u> x <u>5 x 5 </u>x <u><em>3 </em></u>
=600
No. If you make both denominators (aka the bottom number) the same, then you can see 3/4 is greater.
2/6=8/24
3/4=18/24
Answer:
![30-3d\leq 20](https://tex.z-dn.net/?f=30-3d%5Cleq%2020)
Step by step explanation:
Let d represent the rate of temperature decrease in degrees Celsius per day from Monday to Thursday.
As temperature decreased at a constant rate in the next 3 days, so the rate of temperature will decrease 3d degree Celsius in 3 days.
We are told that the pool was open on Monday. The high temperature was
on Monday. So the decrease in temperature from Monday to Thursday will be
.
We have been given that the swimming pool is open when the high temperature is higher than
.
As the pool was closed on Thursday. This means that temperature on Thursday was less than or equal to 20 degree Celsius. We can represent this information in an inequality as:
![30-3d\leq 20](https://tex.z-dn.net/?f=30-3d%5Cleq%2020)
Therefore, the inequality
can be used to determine the rate of temperature decrease in degrees Celsius per day, d, from Monday to Thursday.
14.5+14.5+5.8+5.8= 29+11.6= 40.6 meters
14.5*5.8= 84.10 meters square
