Answer:
To calculate the gradient of a straight line we choose two points on the line itself. From these two points we calculate: The difference in height (y co-ordinates) ÷ The difference in width (x co-ordinates). If the answer is a positive value then the line is uphill in direction.
Answer:
i think it is a
Step-by-step explanation:
= -1/2- (-2/5)
= -1/2 + 2/5
find common denominator (2 goes in 10 five times; 5 goes in 10 twice)
= -(5*1)/10 + (2*2)/10
= -5/10 + 4/10
= -1/10

Answer:
Divide the figure above into a cylinder and a dome
+) the volume of the dome is

the surface area is

+) the volume of the cylinder is

the surface area is

so the volume of this figure is

the surface area of this figure is
