12.57 * 4.11 = 51.66

1257 *remove the decimal and treat the numbers as whole numbers.
 x 411
1257 * 1 x 1257
12570 *10 x 1257
2800 *400 x 7
20000 *400 x 50
80000 *400 x 200
+ 400000 *400 x 1000
516627

516627 is the product of 12.57 and 4.11 without their decimal points.

516627. the decimal point must be moved 4 places because the total count of numbers after the decimal is 4.

from 516627 to 51.6627 ; round to the nearest hundredth 51.66

How is it that a square is a rectangle but a rectangle ins't a square?

Helen [10]

Beacuse A square by definition is a "plane figure having four equal sides." Rectangles' sides are not equal and hence cannot be a square.

A rectangle by definition is a "four-sided plane figure with 4 right angles" - which also implies that a square can be a rectangle because it is also a four-sided plane figure with 4 right angles...... hope this helps

What is the equation of a line going through points (-15,70) and (5,10)

andrey2020 [161]

Simple....

you have:

(-15,70) and (5,10)

Using-->>

$\frac{ y_{1} -y_{2} }{ x_{1}- x_{2} }$

$\frac{70-10}{-15-5} = \frac{60}{-20} = -3$

Using y=mx+b...and any of the coordinates....

70= -3(-15)+b

70=45+b

70=45+b
-45 -45

25=b

y=-3x+25

Thus,your answer.
