Five girls share 4 sandwiches equally. What fraction of a sandwich does each girl get?

Answer:

25.6 units

Step-by-step explanation: From the figure we can infer that our triangle has vertices A = (-5, 4), B = (1, 4), and C = (3, -4).

First thing we are doing is find the lengths of AB, BC, and AC using the distance formula:

d=\sqrt{(x_2-x_1)^{2} +(y_2-y_1)^{2}}

where

(x_1,y_1) are the coordinates of the first point

(x_2,y_2) are the coordinates of the second point

- For AB:

d=\sqrt{[1-(-5)]^{2}+(4-4)^2}

d=\sqrt{(1+5)^{2}+(0)^2}

d=\sqrt{(6)^{2}}

d=6

- For BC:

d=\sqrt{(3-1)^{2} +(-4-4)^{2}}

d=\sqrt{(2)^{2} +(-8)^{2}}

d=\sqrt{4+64}

d=\sqrt{68}

d=8.24

- For AC:

d=\sqrt{[3-(-5)]^{2} +(-4-4)^{2}}

d=\sqrt{(3+5)^{2} +(-8)^{2}}

d=\sqrt{(8)^{2} +64}

d=\sqrt{64+64}

d=\sqrt{128}

d=11.31

Next, now that we have our lengths, we can add them to find the perimeter of our triangle:

p=AB+BC+AC

p=6+8.24+11.31

p=25.55

p=25.6

We can conclude that the perimeter of the triangle shown in the figure is 25.6 units.

Hi there!

Please see the explanation below.

Explanation:

Recall the meanings of the variables in the slope-intercept equation.

⸻⸻⸻⸻

⸻⸻⸻⸻

• We already have one point given, the y-intercept. The y-intercept of a line when given a slope intercept form equation is:  

• Using the example, we would graph the point (0,5) as our first point.

⸻⸻⸻⸻

• To graph the second point, we need to understand the meaning of slope. The slope of a line can be remembered as 'rise over run'.
• The slope for the given equation is -3.
• This means we would have to go three units down and then one unit right from the y-intercept. Our new point would be (1,2).

⸻⸻⸻⸻

• The result should be the graph attached.
