Deanna estimated the product of 6.45 and 10.2. How does the estimate compare to the exact product?

1 answer:

5 0

The estimate should be 60 (because you round down the 6.45 and 10.2 to 6 and 10). Since you rounded down, the actual product will be greater than the estimate.

Well we know that A+B+C=180
and we know that A=45 and B=90
so together there 135
180-135=45
so C=45
now we also know that a straight line is 180 degrees so 180-45 =135(angle f)
135+15(angle e)=150
180-150=30
so angle d=30

0.9 is a rational number since the decimal stops at 9, it's not infinite.
18 is an integer and a whole number. They have the same meaning.

$y = 4^x \quad \to\quad y = - \frac 2 3 (4^{x+7}) - 5$
