Answer: 27.80
Step-by-step explanation:
(3/5) x 14 = 8.4
That's 4 of the 2 kilogram tubs and 1 of the 1 kilogram tub (gives 9 kilograms)
4 x 6.15 = 24.60
1 x 3.20 = 3.20
24.60 + 3.20 = 27.80
Answer:
Step-by-step explanation:
let y=f(x)
y=10x-10
flip x and y
x=10y-10
10 y=x+10
![y=\frac{1}{10}x+1\\f^{-1}(x)=\frac{1}{10}x+1\\(fof^{-1}{x})=f(f^{-1}(x))=f(\frac{1}{10} x+1)=10(\frac{1}{10} x+1)-10=x+10-10=x\\(fof^{-1})(-10)=-10](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B1%7D%7B10%7Dx%2B1%5C%5Cf%5E%7B-1%7D%28x%29%3D%5Cfrac%7B1%7D%7B10%7Dx%2B1%5C%5C%28fof%5E%7B-1%7D%7Bx%7D%29%3Df%28f%5E%7B-1%7D%28x%29%29%3Df%28%5Cfrac%7B1%7D%7B10%7D%20x%2B1%29%3D10%28%5Cfrac%7B1%7D%7B10%7D%20x%2B1%29-10%3Dx%2B10-10%3Dx%5C%5C%28fof%5E%7B-1%7D%29%28-10%29%3D-10)
-3/5 parallel lines have the same slope
These drawings depict the steps to get the perpendicular line using a compas (and maybe a ruler)
remember that a line goes through 2 points so we need 2 different points to construct our perpendicular line
the first one is wrong because it doesn't constraint it to be perpendicular
it only has 1 point,
2nd is wrong as well, has only 1 point, the center
3rd is right
4th is correct, hold a sec
how did that 2nd upper arc have same beginig pointn for compass?
3rd on is answer
