Answer:
no it's not parallel to that.
Answer:
20 km/h
Step-by-step explanation:
the total time is 0.5 hours as the cyclist travels for 30 minutes
the formula for speed is distance travelled divided by time taken which gives us 20 km/hr
The surface area of a cylinder is the sum of the top + bottom + body, right?
The top and the bottom are circles with the same radius 3.5 . And we know that the area of a circle is r^2pi, (don't forget we have 2 circle, so, the answer must be multiplied by 2)
Now, the body: the body is just a rectangular with the width is the height of the cylinder and the length is the circumference of the circle.
The circumference = 2 r pi
the height is given
All you need to do is to calculate them and add them up. You need to work out to get the answer.
N= numerator
D= denominator
N:D ==> 2:3
2:3, 4:6, 6:9... And so on...
The pattern here is that the numerator increases by 2 and the denominator by 3. Easy right?
Now 5 is added to the "n".
Now it is N:D ==> 3:2
3:2, 6:4, 9:6... And so on...
The pattern here is inverted then the 2:3 one.
If I'm right then which one (you might have to continue the process/pattern) then one of them will increase by 5.
3 => 2 = +1 (2+1=3)
6 => 4 = +2 (4+2=6)
9 => 6 = +3 (6+3=9)
12 => 8 = +4 (8+4=12)
15 => 10 = +5 (10+5=15)
18 => 12= +6 (12+6=18)
Q. Which one is +5?
A. 15:10
That is what "I" think it is.
Now, the question is,
Does it work? Does it fit the above description?
Q. Does it even work? Does it fit the above description?
3 + 4x - 3x = 4 ( given )
3 + x = 4 ( combine like terms )
subtract 3 from both sides (subtraction property of equality )
x = 4 - 3
x = 1
