The answer would be 4 1/5 miles.
Answer:
1. 519.75 cm^3
2. 19.22 cm^3
3. 613.6 cm^3
4. 1365.68 cm^3
Step-by-step explanation:
Hello again, similar to the other questions, these problems use the same formulas.
1. volume of a rectangular prism is: V = lwh, where l = length, w = width, h = height. Substitute known values into this equation: V = 4.5 x 7 x 16.5 and we get V = 519.75 cubic cm.
2. V = (1/2)bhl, where the base and height are dimensions of the triangle. V = (1/2)6.2 x 2 x 3.1 and we get V = 19.22 cubic cm
3. V = Bh, where B is the base area and h is the perpendicular height. Substitute known values into equation: V = 52(11.8). So, V = 613.6 cubic cm.
4. And again, V = Bh. Substitute given values into this equation: V = 79.4(17.2), which means V = 1365.68 cm^3
1/3+1/9= 4/9, which is a rational number. 1/3 is equal to 0.333333, which is equivalent to 1/3, while 1/9 is equal to 0.1111111. By adding we get 0.44444444, which is equal to 4/9.
Angle of depression is the angle that is created below the horizontal with your line of sight. to solve the angle of depression, use the formula:
tan(d) = o / a
where d is the angle of depresion
h is the opposite side of the angle which is the height 60 ft
a is the adjacent side of the angle which is 25 ft
tan( d ) = 60 / 25
d = arctan ( 60 / 25)
d = 67.38 degrees
Answer: (55,9) Explanation is below.
Step-by-step explanation:
What you want to do is try to mutliply one of your equations so that either y or x will be canceled out.
Here is the example:
Say you want to get rid of x, you can multiply the first equation: x-5y=10 by -2 to match the second equation: -2x+6y=-16.
Therefore, the first equation would become -2(x-5y=10)=> -2x+10y=-20
Then subtract the first equation from the second:
(-2x+6y= -16)
- (-2x+10y = -20)
-------------------------
=> 0x-4y= -36
Simplify and then you get y=9.
To find x, plug in y into one of the equations: x-5(9)=10 => x-45=10 => x=55
Sorry if I didn't explain it correctly.
Have a nice day! :D
