Answer:
20 hrs
Step-by-step explanation:
20 hours: The volume of the pool is (length) × (width) × (height), or 30×10×2=600 cubic meters. Use a standard work equation, RT= W, where W represents the total work of 600 m

.
0.5×t=600
t=1200 minutes
Convert this time to hours by dividing by 60: 1200÷60=20 hours.
Alternatively, you could convert first:
hr
0.5m
3
×60min=
hr
30m

Next, use the standard work equation:
30 t = 600
t = 20 hours
It must be ≤ instead of ≥.
y ≤ - 3·x + 4
Answer:
Tan is the ratio of "opposite" side to "adjacent side
Cos is the ratio of "adjacent" to "hypotenuse"
Sin is the ratio of "opposite" to "hypotenuse"
We will write the trig ratios with respect to the angle "x"
Opposite Side is "c"
Adjacent Side is "b"
Hypotenuse is the side opposite of 90 degree angle, "a"
Now, let's write the ratios:
Step-by-step explanation:
The mean of the data set is 16
Mean can be described as the sum of values divided by the total number of value in a set of number.
Mean = sum of terms/number of terms
= 8+8+14+18+22+25/6
= 95/6
= 15.8
= 16 (to the nearest tenth)
Hence the mean of the date set is 16
