Answer:
A.
Step-by-step explanation:
Volume of a prism is found with V= B*h. Find the area of the base and times it by the height.
To find the value of x+y, we will first find the sum of all the interior angles of the hexagon.The sum of the interior angles in a hexagon is always equal to 720 degrees.
All the angles in the diagram are in terms of x or y except for angle t. However, we know that the corresponding exterior angle is 30 degrees. The sum of angle t and 30 is 360. We can solve this in an algebraic equation.
t+30=360
Subtract 30 from both sides
t = 330
Now, we can solve for the values of x+y. We can set this up in another algebraic equation.
x+x+x+2y+y+30=720
Combine like terms:
3x+3y+30 = 720
Subtract 30 from both sides:
3x+3y = 690
Divide both sides by 3:

x+y = 230
The sum of x and y is 230.
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).
