Answer : The grain of sand is 50 times greater than the phytoplankton.
Step-by-step explanation :
As we are given that:
Size of phytoplankton = 2 × 10⁻⁶ in
Size of sand grain = 1 × 10⁻⁴ in
Now we have to determine how many times longer the grain of sand is than the phytoplankton.
We are dividing the sand grain size by the phytoplankton size.
This can be done by equating it as follows:
Therefore, the grain of sand is 50 times greater than the phytoplankton.
A = a+b

=52.5
You factor it. so it would be (y-3)(y+6)
Answer:
2 zeros for odd numbers less than 10
3 zeros for even numbers less than 10
Step-by-step explanation:
Non-zero whole numbers less than 10 are;
1, 2, 3,4, 5, 6, 7, 8, and 9
The odd numbers include:
3, 5, 7, and 9
The product of 500 and any of these numbers will contain 2 zeros, the ones in the number 500.
On the other hand, the even numbers include;
2, 4, 6, and 8
The product of 500 and any of these numbers will contain 3 zeros of which 2 are the ones in the number 500 and 1 zero is as a result of multiplying 5 by an even number.
If c = the cost of one table, the cost of all 25 tables before sales tax is 25·c
Since the sales tax is 5%, or 0.05, the sales tax for 25 tables is 25·c·0.05
Adding the sales tax to the original cost of the 25 tables can give you:
25·c + 25·c·0.05 = 1706.25
1.05·25·c = 1706.25
26.25·c = 1706.25
c =
= 65
so the refund for 5 tables would be 5*65 = $325
