Answer:
106
Step-by-step explanation:
The diameter of the wheel is 15 cm or 0.15 m.
The circumference of the wheel is 0.15π m ≈ 0.47 m.
So the wheel moves 0.47 m with each revolution.
The wheel travels 50 m, so the number of revolutions is:
(50 m) / (0.47 m/rev) ≈ 106 revolutions.
Answer:
y = 1/2x represents a direct variation because it represents the direct variation formula: y = kx. In this case, the "k" is 1/2.
the problem would be set up as 6+(7*x)=41
first u take off the number 6 by subtracting it from itself to cancel it out then u do the same to the number 41
7x =41 now u need to cancel out the number 7 attatched to the x so u divikde it by itself and then do the same to the other side so 41 divided by 7 =5.9
so x =5.9
Alright here we go:
First, you would need to do a little cross multiplication/division.
(X is the segment we’re looking for)
You would put 1.5/2.25 and then 1.4/x. After that, multiply 2.25x1.4 to get 3.15. After that divide 3.15 by 1.5 to complete the cross multiplication, getting you 2.1.
So there is your answer, 2.1! I really hope that’s right!
Work wise it should look something like the picture attached, sorry if it’s messy.
Answer:
Th value of u is 1.6
Step-by-step explanation:
In order to find the value of u, you have to multioly both sides by 7 :
