Round them to the nearest 10, soooo
210 divided by 10 equals
around 21
that would be your estimate using compatible numbers.
I hope this helps =)
Answer:
161 bags
Step-by-step explanation:
Since we need to know how many square feet a bag can cover, we need to convert the 1.8 square meters to feet. A meter is about 3 feet and 3.5 inches, so to find how many bags he needs we need to convert the bag into feet. First lets convert the meter into inches:

Remember that a foot is 12 inches. Now, we need to multiply the 39.5 inches by 1.8 to find out how many square inches a bag holds.

We need square <em>feet</em> though, so let's divide our 71.1 inches by 12 to get a foot measurement.

A bag holds 5.93 square feet of mulch. Now, to figure out how many bags he needs, we need to divide 950 (total area to cover) by 5.93 (area each bag covers).

Since Bill cant buy a fifth of a bag, we need to round up so he has enough. So, Bill needs 161 bags of mulch to cover his yard.
D. 4 nickels.
This is because when she has 4 nickels that equals 20 cents. And that means that the rest are dimes. So a dollar worth of dimes would be ten dimes. and Ten dimes and 4 nickels equal 14 coins and $1.20

add together
Step-by-step explanation:
the perimeter = 2 ×15 + (π×d)
= 30 + (3.14 ×10)
= 30 + 31.4
