Oscar ran the 100-yard dash in 12.65 seconds. Jesiah ran the 100-yard dash in 11.57 seconds. How many seconds faster was Jesiah's time than Oscar's time?

Jesiah's time was faster than Oscar's time by seconds.

Jesiah's time was faster than Oscar's time by 1.08 seconds.

Step-by-step explanation:

To find how much faster Jesiah ran than Oscar, subtract Oscar's time with Jesiah's time.

12.65 - 11.57 = 1.08

Jesiah was faster than Oscar by 1.08 seconds.

Good luck ^^

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
