Ethan sold 2/3 gallon of lemonade. kayla sold some too. together they sold 1 1/4 gallons. who sold more lemonade, ethan or kayla? how much more?

 Ethan sold more lemonade than Kayla by

Step-by-step explanation:

Since we have given that

Quantity of lemonade sold by Ethan is given by

Quantity of lemonade sold by Ethan and Kayla together is given by

Quantity of lemonade sold by Kayla only is given by

To get who sold more lemonade we will first make the denominator same ,

Denominator of 3 and 12 = 12

So,

Compare Ethan and Kayla ,

We know that

So, Ethan sold more lemonade than Kayla .

By

Hence, Ethan sold more lemonade than Kayla by

step-by-step explanation:

the value of v.w= -12.

step-by-step explanation:

we are given three vector r,v and w as:

r = < 5, -5, -2> ; v = < 2, -8, -8> ; w = < -2, 6, -5>

we know that r,v and w could also be represented as:

r=5i-5j-2k

v=2i-8j-8k

and w= -2i+6j-5k

where i,j and k are the unit vectors of x,y and z-axis respectively.

also we know that it has the following property:

i.i=1 ; j.j=1; k.k=1

and i.=j.i=i.k=k.i=j.k=k.j=0

i.e. when we multiply two vectors or we find it's dot product we need to only multiply the components of x coordinates with each other; y with each other and z with each other.

hence, v.w= (2i-8j- -2i+6j-5k)

                  = 2×(-2)+(-8)×(6)+(-8)×(-5)

                  = -4-48+40

                  = -12

hence, v.w= -12
