The image is blurry what’s the question?
This does not sound like a school problem, nor mathematics.
However, since it is an interesting question, I will provide an answer, at the risk of both answer and question being deleted.
Rock (stones, minerals) can be made into spheres in a very ingeneous way.
We have a rotating drum very similar to a clothes dryer. Inside, we put the rock or rocks intended to be cut/made into spheres. We add coarse abrasives, like sand, crushed diamond... depending on the material the rock is made of. We then let the drum rotate for a long time until the rock is spherical. However the surface will still be rough. If we want that smooth, we have to replace the abrasive completely with a finer grade of abrasive, progressively, until the abrasive produces a smooth surface on the rock.
In fact, a machine based on the same principles is used to peel potatoes. Nowadays, most potato chips are done in factories and most of them not peeled.
Step-by-step explanation:
It doubles in value every 30 years, which means it increases by 100%.
A = 60,000 (1 + 1)^(t/30)
A = 60,000 (2)^(t/30)
In 2035 (55 years later), the value is:
A ≈ 214,000
Number of games won/Number of total games played x 100%
52/66 x 100% = 78.79%
Hope u understood! :)
Answer:
3/2
Step-by-step explanation:
3x-2y=-14
2y=3x-(-14)
2y=3x+14
y=3/2x+14/2
y=3/2x+7
y=mx+b where m=slope and b=y-intercept,
so the slope is 3/2.
