Answer:
Area of sphere is given by · ·
Step-by-step explanation:
The surface area of sphere is given by:
· ·
Option C and D are correct but is missing in the options
Option A and B are incorrect.
to solve the area of sphere when radius is given a constant value.
X and y are the times in hours that he travelled on foot and on bus
x + y = 1.5 * by 5:-
5x + 5y = 7.5
5x + 60y = 35 subtract:-
55y = 27.5
y = 0.5
and x = 1.5 - 0.5 = 1
so he walked for 1 hour
distance he walked = average speed * time = 5*1 = 5 miles.
-20 > 4 -2x Write the equation.
-20 -4 > 4-4 - 2x Subtract four from both sides.
-24/-2 > -2x/-2 Divide -2 on both sides.
Now, flip the inequality sign.
12 < x
