Answer:
The cost of the old ball was $100.
Step-by-step explanation:
The cost of the new ball = $300
The new ball has three times the price of his old ball.
So, let the price of the old ball be = x
As per situation, we get the equation:
Dividing both sides by 3:
=> x = 100
Hence, the cost of the old ball was $100.
Answer:
Since we do not know the balance we should start with, a general answer:
598 - 47,27 = 550,73, assuming b_old was 0$ for your example
Step-by-step explanation:
b stands for balance (old - before any deposits or withdrawals, new after all done)
d for deposits
w for withdrawals
Answer:
12862.83cm³
Step-by-step explanation:
Volume of the Box: [L×W×H] or [30x30x30] or [27000cm³]
Volume of the Sphere: [] (
=pi=3.14) (r=radius=15) or [
×3.14×3375] or [14137.17cm³]
Volume of the empty space: 27000cm³-14137.17cm³=12862.83cm³
Btw there are online tools to help you find the volume of a sphere (just use it after you understand the equation)
Hope I helped!
