9. the approximate circumferences of earth

and saturn are shown. how many times

greater is the circumference of saturn than

the circumference of earth?

c = 365,882 km

the circumference of saturn is

x 10 km.

c = 4,01 x 104 km

saturn's circumference is about times

greater than the circumference of earth.

(4 x .01x104)

400,000

4x 103 km

10. estimate 0.037854921 to the nearest hundredth.

11. compare the numbers 6 x 10-6 and 2 x 10-8.

Answer and explanation:

1) Given : Circumference of Earth

Circumference of Saturn

To find : How many times  greater is the circumference of Saturn than  the circumference of Earth?

Solution :

Let x be the number of times greater is the circumference of Saturn than  the circumference of Earth.

According to question,

Therefore, 9.124 times  greater is the circumference of Saturn than  the circumference of Earth.

2) Number  0.037854921

Estimate to the nearest hundredth.

The hundredth number is 3 and thousandth number is 7.

As thousandth number 7 is greater than 5.

So, hundredth number is added by 1 and rest became zero.

i.e.

3) Compare the numbers and

As the denominator is same compare the numerator,

0.02<6 or 6>0.02

So,

Therefore, is greater than

add an !
