Answer:

  (x, y) = (5, 9)

Step-by-step explanation:

We must find the value of x before we can find the value of y. Fortunately, simply adding the arcs around the circle will give an equation for x.

  25x +20x +7x +20x = 360 . . . . angles in degrees

  72x = 360 . . . simplify

  x = 5 . . . . . . divide by 72

__

The value of the external angle at J is half the difference of arcs GL and HK. That is, ...

  5y = (25x -7x)/2 = 9x = 9(5) . . . . simplify, fill in for x

  y = 9 . . . . . . divide by 5

__

  (x, y) = (5, 9)

Can someone help me with this two because I am very confused
Tasya [4]

Answer:

Let the height of the larger box = h

and length and width of the larger box = l and w , repectively

Now , Let find the volume of the larger box

Volume = length * width * height

So Volume of the larger box = l*w*h = lwh

Now the question says

the height of the smaller box is 80% of the height of the larger box

It means

Height of the smaller box = 80% of h = 0.80*h = 0.80h

and the other two dimensions are same so it means length and width of the smaller box = l and w

so, Volume of the smaller box = l*w*0.80h = 0.80lwh

So the Difference in the volume of the two boxes = Volume of larger box - Volume of smaller box

therefore , Difference in the Volume of two boxes = lwh - 0.80 lwh = 0.20lwh

Step-by-step explanation:

Which of the equation is graphed below
Darina [25.2K]
A, because 1/4 is your slope of the line. which means you find a point where the line intersects and count 1 up and four over to the right and should end up where the line touches the graph again. if it were to be -1/4 it would be opposite and the line would be going the other way. and 1 would be your y-intercept. this is where the line crosses over the y axis at 1! hope you found this helpful!
