Answer:
C)
Step-by-step explanation:
Set each side of the equation equal to y, then rearrange to standard form.
(1/2)x -5 = y . . . left side of the equal sign
x -10 = 2y . . . . multiply by 2
-10 = 2y -x . . . . subtract x
__
(1/3)x +6 = y . . . right side of the equal sign
x +18 = 3y . . . . . multiply by 3
18 = 3y -x . . . . . subtract x
The corresponding system of equations is ...
Answer:
b
Step-by-step explanation:
(1/2)÷4=1/8
so it is one in 8 parts.
Answer: I assume you mean surface area of a sphere.
The formula is 4πr²
If radius=3, then:
4 times 
times 3²
4 times times 9
= 113.142857
Rounded to 1 decimal place = 113.1
<u>NOTE: In place of π you can also use 3.14.</u>
Answer:
- 76.2% total return
- 2.87% annual return
Step-by-step explanation:
The total return is the rate of increase over the whole period:
% change = (11100/6300 -1) × 100% = 76.2%
The annual return is the rate of return that gives this growth over 20 years:
(1 +r)^20 = 1 +76.2%
r = 1.762^(1/20) -1 ≈ 2.87%
The total return is about 76.2%; the annual return is about 2.87%.
