Answer:
You can't do this without knowing the number of hours, but you can write an equation. The equation would be 12p. P means the number of hours they worked and 12 stands for how much they earn each hour. Therefore you would multiple both of them together.
We need to find the interest rate in order to solve this problem:
.12/12 = (.01)
The number of years is unknown. T represents time in the following formula:
1000 (initial investment)
2000 (balance after t years from investment)
=$2000
In order to isolate the exponential term, both sides must be divided by 1000.
=2
By using natural logarithm:
By dividing both sides of the equation by 
The slope from (2,5) to (4,9) is 4/2 or just 2.
A perpendicular will have a gradient of -1/2
The midpoint is (3,7)
Therefore y=mx+c becomes 7=-1/2 x 3 + c
c = 7 + 3/2
The perpendicular bisector has the equation y = -1/2x + 17/2
Answer:
x=30
Step-by-step explanation:
So we know that a shape with 4 angles equal 360 degrees and this has 4 angles. Since we know that 4x is one and 2x is one We cna use the vertical angles to find the other two. Since 4x is opposite of an unknown side it is also 4x becuase vertical angles are equal becuase they are opposite sides of each other. Same thing with 2x
Now add them all up
4x+4x+2x+2x which will equal 12x
now 12x=360
x=30
