12.50 x 2= 25
25+15.99= 40.99
40.99 x 7.5%= 3.07
40.99+3.07= 44.06
Answer is $44.06
So a side must be the square root of 57 which is not a rational number. It is the square root of 57 because let’s say you have a square and a side length is 2, so the area is 4 if we reverse the process square root of 4 which is 2.

Hi there!
Let's use the formula of a sphere and divide it by two (for each hemisphere) to find the volume. Then, we'll create a ratio to figure out how many times larger the larger hemisphere is.
WORK:
Larger hemisphere:
V = 2/3(pi)(8^3)
V = 2/3(512pi)
V = 341.33pi
Smaller hemisphere:
V = 2/3(pi)(4^3)
V = 2/3(64pi)
V = 42.66pi
Ratio:
341.33/42.66
Approximately 4 times
ANSWER:
The larger hemisphere is approximately 4 times bigger than the smaller hemisphere
Answer:
1. 2
2. 2
Step-by-step explanation:
1.
2x+1 = x+3
-x -x
x+1 = 3
-1 -1
x=2
2.
3x-4 = x-8
-x -x
2x-4 = -8
+4 +4
2x = -4
/2 /2
x = 2
