William estimated √140 by placing a point on the number line below. Which is true about his estimate? please guys I need this du
garik1379 [7]

Answer:

Step-by-step explanation:

Familiarize yourself with perfect squares in the neighborhood of 140:

10^2 = 100

11^2 = 121

12^2 = 144

Note that 140 is much closer to the perfect square than it is to the perfect square 121.  The value of √140 must lie closer to 12 than to 11.

Place a point on the number line about 3/4 of the way from 11 to 12.

Answer:

1. 135

2. 114

3. .19

4. 170

5. 336

6. 106.25

7. No, the associative property does not work for subtraction or division, they do not hold for the associative property. For example,

2+ (3+4) = (2+3) + 4       2- (3-4) = (2-3) – 4

2+7 = 5+4                      2 + 1 = -1-4

9 = 9                              3 = -5, which is not true

8. No, the commutative property does not work for subtraction or division, they will give a different result. For example,

5+6 = 6+5        5-6 ≠ 6-5
