True, because all angles on a straight line add up to 180 deg
2.40 / 8 = 0.3
0.3 * 3 = 0.9
Answer: 0.9 is 3/8 of 2.40
This question involves direct proportion which has the formula (y=kx) where y and x are the values which are proportional and k is the constant of proportionality.
The constant of proportionality is basically the value that stays the same even if the x and y values change.
In this case, the constant of proportionality would be 3/7.
Answer:
Distance = time * speed
let x be rate of the cyclist
x-12 = the rate of the jogger
they have the same time
so: 12mi/(x-12)mph = 24mi / x mph
12x=24(x-12)
288=12x
x=24
rate of the cyclist =24 mph
rate of the jogger = 12 mph
1. Draw the perpendicular line to the given line that passes through the point Q. With this aim you should draw a circle with center at point Q and radius that is greater than distance form point Q to the given line. Then match these two points of intersection of this circle with given line as A and B and draw two circles with centers at points A and B and radii that are greater than half of distance between points A and B. These two circles will intersect, combine two points of intersection of these points, this line will be perpendicular to given line.
2. Draw a circle with center at Q and match two points of intersection with perpendicular as E and F.
3. Draw two circles with centers at points E and F and radii that are greater than radius of previous circle. Combine two points of intersection of these circles, this line will be parallel tj the given line.
Taking into account the solution, you can conclude that correct choice is B.
