At 3pm, the temperature outside was 5 1/5 degrees fahrenheit. the temperature then fell steadily by 2 1/2 degrees per hour for the next four hours. what was the temperature at 7pm? plz answer this i will give you 100 points

- 4 3/4 degrees Fahrenheit.

Step-by-step explanation

From 3 to 7 pm is 4 hours, so

Temperature at 7 pm =  5 1/4 - 4 * 2 1/2

=  21/4 - 4 * 5/2

= 21/4 - 10

=  21/4 - 40/4

= -19/4

= - 4 3/4 degrees F

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
