Answer:
51.02 metres
Step-by-step explanation:
The pictorial representation of the problem is attached.
We are required to find the distance from the worker to the top of the pole, |DA| in the diagram.
In Triangle ABC
In Triangle BCD
The distance, |DA| =|AB|-|BD|
=72.73-21.71
=51.02 metres
The distance from the worker to the top of the pole is 51.02 metres.
mean would be adding them all up and dividing by how many there is mean median mode and range but the mean absolute deviation would be actually can't tell you cuz I don't know myself but you could probably look it up I wish you the best of luck
Answer:
The answer to your question is Vc : Vs = Ac : As =
Step-by-step explanation:
Process
1) Volume of a cylinder = Vc = πr²h
Volume of a sphere = Vs = 4/3 πr³
Vc : Vs = πr²h / 4/3πr³
= 3/4 πr²h / πr³
= 3h / 4r
=
2)
Area of a cylinder = 2πr² + 2πrh
Area of a sphere = 4πr²
Ta cylinder : Ta sphere = (2πr² + 2πrh)/ 4πr²
= 2πr²/4πr² + 2πrh/4πr²
= 1/2 + h/2r
=
Answer:
x=5 and y=5
Step-by-step explanation:
You "plug" one equation into the other, to get a new equation that only has one variable (x or y), then you can simplify that and have your answer.
So let's plug the first into the second:
First, we convert the first equation into an x=... form. For this one, this means moving the +y to the other side:
x = 10 - y
Now we substitute 10-y for x in the second equation:
So 2x+4y=30 becomes:
2(10-y) + 4y = 30
And simplify that:
20 - 2y + 4y = 30
20 + 2y = 30
2y = 30-20
2y = 10
y = 5
This is the first answer! If we put this into the first equation, we get:
x = 10 - 5 = 5
Now we have both answers, x=5 and y=5
