1.	After being exposed to an electromagnetic shrinking machine, Joe's height decreased by 120 cm over 1.5 seconds. His height decreased by the same amount each second. How much did Joe's height change each second?
Answer» 80 cm/sec Step-by-step explanation: It is given that Joe was being exposed to an electro MAGNET SHRINKING machine. Because of this his height started decreasing. The decrease was at a constant rate per second is given. In 1.5 seconds, the height decreased by 120 cm. Since given as constant decrease per second we find that this is DIRECT variation of height over second. variation per second = \begin{lgathered}\frac{120}{1.5} \\=\frac{1200}{15} \\=80 cm\end{lgathered} 1.5 120 = 15 1200 =80cm Change in each second would be with negative SIGN INDICATING decrease Answer is -80 cm/sec

Answer»

80 cm/sec

Step-by-step explanation:

It is given that Joe was being exposed to an electro MAGNET SHRINKING machine.

Because of this his height started decreasing.

The decrease was at a constant rate per second is given.

In 1.5 seconds, the height decreased by 120 cm.

Since given as constant decrease per second we find that this is DIRECT variation of height over second.

variation per second = \begin{lgathered}\frac{120}{1.5} \\=\frac{1200}{15} \\=80 cm\end{lgathered}

1.5

120

1200

=80cm

Change in each second would be with negative SIGN INDICATING decrease

Answer is -80 cm/sec
