the answer is A 160.68 dollars. there is pictures of my work shown as well. That is your answer by the way.
Answer:
7.07
Step-by-step explanation:
Angle M is 63 degrees because all 3 angles must add to 180.
Now use the law of sines:
sin(90)/x = sin(63)/6.3
Cross multiply: 6.3 sin (90) = x sin (63)
Divide by sides by sin (63): (6.3 sin (90))/sin (63) = x
Use a calculator: 7.07
Answer: D) Groundwater collects only where the soil and geological features allow water to seep down into underground chambers.
In other words, as long as there are gaps to allow water through, then that would lead to underground aquifers. Another important component is the amount of rain water that happens. Sources such as rivers, lakes and streams are also a contributing factor.
Stuff like earthquakes, volcanic activity, and continental movement doesn't really have much an effect on where or how aquifers form. It's really all about the soil type and how the landscape is formed, and of course the other factors mentioned in the previous paragraph.
Answer:
Step-by-step explanation:
The equation is 3x - 5y =20.
Suppose we start with (5, y). What value of y is a solution of this equation?
Substitute 5 for x in 3x - 5y =20, obtaining: 3(5) - 5y = 20.
Then -5y = 5, and y = -1. Thus, (5, -1) is a solution of 3x - 5y =20.
Next:
We have (x, 2). Find the value of x that makes (x, 2) a solution of 3x - 5y =20.
Replace y with 2: 3x - 5(2) =20
Then 3x = 30, and x = 10. So (10, 2) is a solution of 3x - 5y =20.
Answer:
x = 7
Step-by-step explanation:
L and M would be parallel if angle 2x -3 and the angle x + 4 are equal.
Thus, 2x - 3 = x + 4, so that x = 7
