Answer:
66 degrees
Step-by-step explanation:
if there are 66 one degree angles, all alll those together to get 66 degrees in total
Answer:
A) y= 40x+100
B) 
Step-by-step explanation:
To solve this, we can set up an equation using y=mx+b.
'b' is the initial cost, whereas 'm' is the monthly cost. This gives us the equation:
A): y=40x+100.
For part B, we can solve for the inverse by switching the x and y. This gives us:
x= 40y+100
Now, continue simplifying to isolate the 'y' on a side:
x-100=40y
Just divide the numbers by the totals to get the percentages
Answer:
42.6cm
Step-by-step explanation:
The sum total of all the sides of the shape is the perimeter of the shape. Hence;
Perimeter = x+3 + 4 + x+9 + 2x+5
Perimeter = 4x + 21
Given
Area of the figure = 75cm^2
Area = (x+3)(2x+5) + (2x+1)(6)
75 = 2x²+5x+6x+15+12x+6
75 = 2x²+23x+21
2x²+23x+21-75 = 0
2x²+23x-54 = 0
x = -23±√23²-4(2)(-75)/4
x = -23±√529+600/4
x = -12±√1129/4
x = -12+33.6/4
x = 21.6/4
x = 5.4
Recall that;
Perimeter = 4x+21
Perimeter = 4(5.4) + 21
Perimeter = 21.6+21
Perimeter = 42.6cm
Hence the perimeter is 42.6cm
