Answer:
Yes, 500 texts.
Step-by-step explanation:
If you write out the equations, you can just set them up equal to each other and simplify.
A = .05x + 20
B = .07x + 10
.05x + 20 = .07x + 10 (subtract 10 from both sides)
.05x + 10 = .07x (subtract .05x from both sides)
10 = .02x (multiply both sides by 50
x = 500 texts
B

2:1.
The area of a red curved surface = 2πr^2.
The area of the yellow flat surface = πr^2.
This is the case for all the hemispheres.
Therefore the required ratio = 2πr^2 : πr^2
= 2:1.
