Answer:
x=4
Step-by-step explanation:
Let he first piece be x the second be 3x and the very last one be 7x + 2
Add all the pieces together and you ought to get the length of the rope which is 46 ft
So your equation would be
x + 3x + 7x + 2 = 46
11x = 44
x = 44 / 11
x = 4
so the 3 pieces are 4 , 12 and 30ft
Answer:
Step-by-step explanation:
The volume of a cylinder is ![V = \pi r^{2} h](https://tex.z-dn.net/?f=V%20%3D%20%5Cpi%20r%5E%7B2%7D%20h)
Known facts:
- radius: 17m (half of the diameter which is 34m)
- height: 27m
is 3.14
Let's set up the equation:
cubic meters
Answer:
I would say D
Step-by-step explanation:
I showed the work for the first question in the image attached. For the second question, it's C
First find the slope of the given line. 6x+4y=3. Isolate y. 4y=-6x+3, y=-3/2x+3/4.
The slope is -3/2. A perpendicular slope would equal the negative reciprocal of -3/2, which is 2/3.
The answer would be any line with a slope of 2/3 (ie y=2/3x-1).
To check, graph the given and derived equation.
