Challenge in City A, the temperature rises 6°F from 8 Am. to 9 Am. Then the temperature drops 5°F from 9 A. m. to 10 a. m. In City B, the temperature drops 1°F from 8 A. m. to 9 Am. Then the temperature
drops 3°F from 9 a. m. to 10 A. m. Write an expression that represents the change in temperature from 8
A. M. to 10 A. m. for each city. Simplify and interpret each sum.
Use pencil and paper. Which city has the greater change in temperature?
Which expression represents the change in temperature for City A?
OA. - 6+(-5)
OB. - 6+5
OC. 6 +5
OD. 6 + (-5)

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.

answer

you start with $5 and save $10 a week until you have at least $45wer

step-by-step explanation:

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:
