Well 30m for 50 km so 900/50 is 18 is 9 hours so it would take 9 hours
Answer:
y = -3/8x - 9/4
Step-by-step explanation:
Since we know the equation is parallel to y = -3/8x + 2, the slope of our equation will also be -3/8
So our equation can be written as:
y = -3/8x + b
To find 'b', we can plug in the point (2, -3) into the equation:
-3 = -3/8 * 2 + b
b = 3/4 - 3 = -9/4
So our final equation becomes:
y = -3/8x - 9/4
First step is to convert feet to kilometers. 2 kilometers is approximately equal to 6,560 ft.
Keeping that number in mind, we need to find the circumference of the circle. We need this number because that is the exact distance the wheel will travel in a single revolution. We can use the equation c=pi(d) to get it, or use the more commonly cited formula c=2pi(r), with a few added steps. Since we're given the diameter, not the radius, the first formula makes more sense.
The circumference is roughly equal to 6.28. That means the bike travels 6.28 feet for every complete revolution. Since that's 6.28 feet for every SINGLE revolution, we can simply divide the total distance the bike traveled (6560 ft) by the distance which it travels per revolution (6.28).
6560 ft divided by 6.28 ft/1 revolution = 1044.59 revolutions.
Answer:
all u need to do is look for the relation b/w the values given to u
Step-by-step explanation:
here it would be the formula of finding the volume of a cone
=> (1/3) (pi) (r)^2 (h) = 1526.01
=> r^2 = (1526.01 x 3) / ( 3.14 x 18)
=> r = √80.99
=> r = 8.99
therefore, diameter = 2 x radius
= 2 x 8.99 = 17.9
Answer:
28 questions
Step-by-step explanation:
80% is 80 out of 100, so we can represent it as 80/100.
80 / 100 = y / 35
We need to find the value of y.
To do this we can cross multiply, with a method I like to call the butterfly method.
80 y
100 35
80x35=2800
Therefore, 100 times y equals 2800.
So we divide 2800 by 100.
2800/100=28.
Therefore, y equals 28.
y=28.
