Answer:
48
Step-by-step explanation:
multiply length times width divide by 2
X= 6y
x + y = 525
solving these two equations
6y+y = 525
y = 75
x = 6*75=450
Total revenue = 450 * .03+ 75 * .05
= 17.25
The slope can be worked out by the equation:
So with the coordinates (1,2) and (-2,4):
x1 = 1 y1= 2 and
x2 = -2 y2 =4
Note that x1 and y1 use the same coordinate, vice versa with x2 and y2.
Tip: The equation can be y1-y2 and x1-y2 too (have a think why)
![\frac{(y2 - y1) }{(x2-x1)}](https://tex.z-dn.net/?f=%5Cfrac%7B%28y2%20-%20y1%29%20%7D%7B%28x2-x1%29%7D)
![\frac{(4 - 2) }{(-2-1)}](https://tex.z-dn.net/?f=%5Cfrac%7B%284%20-%202%29%20%7D%7B%28-2-1%29%7D)
So the answer is 2/-3, which is the same as C)
-2/3
Answer: 60 degree
Explanation: The sum of the three interior angles of a triangle is always 180°.
180-80-40=60 degree.
The range is the difference between the largest number and the smallest number. This means you subtract the smallest number from the largest number. If the range is 8, then you can add 8 to the smallest number on the list to get the largest number, m.
Our smallest number is 12, so add 8 to 12.
8 + 12 = 20, so m is 20.
I hope this helps!
