A 5 pound box of detergent costs $0.175 per load ($3.50÷20). 
One load of laundry takes 0.25 pounds of detergent (5÷20). This means a 15 pound box can wash 60 loads of laundry (15÷0.25).
A 15 pound box costs about $0.167 per load ($10÷60).
Using a 15 pound box, you will save $<span>0.008 per load ($0.175-$0.167).</span>

By the Triangle Inequality Theorem, if two sides of a triangle have lengths of 6 and 13, what are the possible lengths of the th
melamori03 [73]
The <span>Triangle Inequality Theorem establishes that the length of the triangle is shorter than the sum of the two lenghts of the others two sides. Then, you have:

 a=6   (the lenght of a side of the triangle).
 b=13   (t</span>he lenght of a side of the triangle).<span>
 c=x    (the length of the third side).

 Therefore:

 c<a+b
 c<6+13
 c<19

 The lenght of the third side is:

 (13-6)<c<19
 7<c<9</span>

(x - 5)(x-4)

= x(x) - 4(x) - 5(x) - 4(-5)

= x^2 - 4x - 5x + 20

Which of these triangle pairs can be mapped to each other using a single translation?
sergeinik [125]

Answer:- D shows the triangle pairs which can be mapped to each other using a single translation.


Explanation:-

Translation is a rigid transformation which creates a congruent image as that of the original figure such that the distance between the each point of the original figure and the image is fixed and same.

The translation mapping is given by (x,y)→(x+h,y+k) ,where h is the distance of the x coordinate of the each point of the original figure to the image and  k is the distance of the y coordinate of the each point of the original figure to the image.

In figure D we can see that the distance between each point of ΔCED is equal to the distance between each point of ΔMPN. Thus it shows  the triangle pairs which can be mapped to each other using a single translation.
