Answer:
tan (48°19'23'') => 1.1232
Step-by-step explanation:
60' minutes are present in a degree, and 60 * 60' seconds are present in a degree;
48°19'23'' = 48 + 19/60 + 23/3600
= 
= 
= 
= 48.323°
tan(48.323°) = 1.1232
Answer:
a) The average global surface temperature in 2100 is 10.7°C
b) b) The slope of the function, 0.01, represents the rate of yearly increase of average surface temperature on the planet and the intercept represents the average surface temperature on the planet in 1900 (the reference year that the average surface temperature for subsequent years are calculated with respect to).
Step-by-step explanation:
T = 0.01t + 8.7
To predict the temperature of the planet in the year 2100.
We will calculate the number of years that 2100 is, since 1900
t = 2100 - 1900 = 200 years
T = (0.01 × 200) + 8.7 = 10.7°C
The average global surface temperature in 2100 is 10.7°C
b) The slope of the function, 0.01, represents the rate of yearly increase of average surface temperature on the planet and the intercept represents the average surface temperature on the planet in 1900 (the reference year that the average surface temperature for subsequent years are calculated with respect to).
To find miles per hour:
3 3/5 miles divided by 4/5 hour
3 3/5 = 5*3 + 3 = 18/5
18/5 divided by 4/5 equals
18/5 times 5/4
The fives cancel out, and we have 18/4 which reduces to 9/2 or 4 1/2 miles per hour :)
Answer: 3/6 and simplfied is 1/2
