For this, look at the 6th digit (hundred-thousands). If that digit is more than or equal to 5, then the next digit is rounded up. Since it is, the answer becomes 35,000,000.
Answer: 35,000,000
Solution :
It is given that four different prizes were awarded. So,
a). 4 ways for person 47 to win a prize
99 ways to give out the 2nd prize
98 ways to give the 3rd prize
97 ways to give the last prize
∴ P(99,3) = 99 x 98 x 97
b). 1 way to give person 47 their prize
1 way to give person 19 their prize
98 ways to give out the 3rd prize
97 ways to give out the last prize
So, P(98,2) = 98 x 97
D. 7.1
A circle has an area of 40 square meters. Which answer is closest to the measure of its diameter?
(3s^13)(9s^-5) is simply a matter of multiplication.
First, multiply the coefficients, or the numbers in front of the s. In this case, 3s x 9s = 27s.
When multiplying exponents, you simply add them, so the next step is 13-5 or 8. Therefore your answer is 27s^8
