this can be solve using the formulaP = rghwhere P is the total pressurer is the densityh is the heightg is the acceleration due to gravity
fist solve the total pressureP = 1.5 bar + 1 barP = 2.5 barP = 250,000 Pa
P = rgh250,000 = (997)(9.81)hh =25.56 m
Answer:
120° and 240°
Step-by-step explanation:
The given info about the angle x is cos x = - 1/2.
By definition, cos x = - 1/2 = (adjacent side) / hypotenuse, so here we can assume the adjacent side is -1 and the hypotenuse is 2.
A negative cosine tells us that the angle is in Quadrant II or Quadrant III.
If x is in Quadrant II, then its value is 120°
If x is in Quadrant III, then its value is 120° + 120°, or 240°

Answer:
2, 1, 3, 4
Step-by-step explanation:
For future reference:
Make all the numbers (accept for the second one) into a common form. For example a decimal.
For the first one, it will simplify into 3/2 since both 9 and 4 can be easily rationalized.
The second can't be written as a decimal, but it will easily become the least greatest number.
The third is already a decimal and the fourth could just be divided 5/3 using a calculator.
From there you'll have
1.5, /5, 2.5, and 1.67
Answer:
D)65
Step-by-step explanation:
Striking deviations are any values outside the normal trend of the data. The data set has an interquartile range of 22. If you look at the values that are on the low end you see -5, which is close to the next value of -3 as well as Q1 of -2. On the high end you see the value of 65, which is a long way off to the next value of 37 and even further off from Q3 of 20. A striking deviation would be 65
