Answer
1/9
Step-by-step explanation:
the chance that she gets it one day is 1/3 so you multiply that by 1/3 because there are three days.
The first thing we must do for this case is to define a variable:
x: number of years
y: total salary
We have then:
For first company:
y = 1500x + 31000
For second company:
y = 2000x + 28500
Equaling both equations we have:
1500x + 31000 = 2000x + 28500
Clearing x:
2000x - 1500x = 31000 - 28500
500x = 2500
x = 2500/500
x = 5
Answer:
It will take for the salaries to be the same about:
x = 5 years
Answer:
x^2 + 8x - 65 = 0.
Step-by-step explanation:
In order to solve the side of the enlarged area of 81 square inches, we use the equation in solving the area of a square. Area = side^2.
the increase in side will be x, so (4+x)^2 = 81, x^2 + 4x + 4x + 16 = 81
x^2 + 8x + 16 - 81 = 0
x^2 + 8x - 65 = 0.

Step-by-step explanation:
Answer:
V = a³/8
Step-by-step explanation:
The volume of the original cube is the cube of the side length:
V = a³
When the side length is reduced to half its former value, the new volume is ...
V = (a/2)³ = a³/2³
V = a³/8 . . . . volume of the new cube
