Answer:
C. 5units
Step-by-step explanation:
<u>A. 587 * 92</u>
We are rounding these factors to the nearest ten, so 587 becomes 590 and 92 becomes 90.
Now multiply 590 and 90.
590 * 90 = 53,100; 59 * 9 = 531, and then add on the two zeroes.
The following answer of 54,004 is reasonable because it is close to our estimate of 53,100.
<u>B. 117 * 19</u>
Rounding these numbers to the nearest ten, you make 117 become 120 and 19 become 20.
Multiply 120 and 20.
120 * 20 = 2,400; I multiplied 12 and 2 to get 24, then added on the two zeroes.
The following answer of 222.3 is not reasonable because it is way off from 2,400. They are about 1,200 apart.
Answer:
you're right it is 3 cause a squares sides are all equal and the only number that can multiply by itself to get 9 is 3.
