Answer: 8/15
Step-by-step explanation:
(-4/5) divided by (-3/2) becomes (-4/5) x (-2/3) because when dividing fractions, change it to multiplication and flip the divider (in this case -3/2)
Multiply numerators to get 8 and denominators to get 15 resulting in 8/15
Answer:
An ellipse
Step-by-step explanation:
Take a cone and make a diagonal cut through it, removing a very thin slice. The result is an ellipse.
a /\
/ \
/ \ b
/ \
Make a straight line from a to b, it will make an elliptical shape. If we cut perfectly horizontally, we would get a circle, when we angle the cut of our cross section, the shape gets more and more elliptical depending on the angle of the cut

Answer:
The last gearwheel would make 3 revolutions.
Step-by-step explanation:
The measure of the revolution of a gear per minute is referred to as the speed ratio. The speed ratio is the ratio of the speed of the driver gear to that of the driven gear, or ratio of the number of teeth of the driven gear to the number of teeth of the driver gear.
In the given question, the second and third gears are idlers. while the first is the driver and the fourth the driven.
The revolution of the last gearwheel can be determined by;
Speed ratio =
=
=
Speed ratio = 1 : 3
The last gear would make 3 revolutions.
