8 0

The number would be 826. 826 rounded to the nearest ten would be 830 because when you have a number at the end that is 5 or higher, it would round up.

What is 9.562359123571283578 rounded to the nearest hundredth?

Katyanochek1 [597]

9.56 because you don't round up when two is the next number. (The hundredths place is the second number after the decimal, where the 6 is in the original number.)

Problem Solving (M1) About 100,000 people live in a town. The number 100,000 can be written as 10n, where n is a whole number. W

vlabodo [156]

Answer:

n = 5

Step-by-step explanation:

100,000 = 10^n

Take the log of both sides

log 100,000 = log 10^n

log 100,000 = n * log 10

Dividing both sides by log 10

log 100,000 / log 10 = n * log 10 / log 10

n = log 100,000 / log 10

= 5 / 1

n = 5
