Alicia paid $1.32 for a bag of pinto beans. the beans cost $.55 per lb. how much did the bag of pinto beans weigh

2.4 pounds.

Step-by-step explanation:

We have been given that Alicia paid $1.32 for a bag of pinto beans. The beans cost $0.55 per lb. We are asked to find the weight of pinto beans bag.

To find the weight of pinto beans bag, we will divide amount paid for the bean bag by per pound of beans.

\text{Weight of pinto beans bag}=\frac{1.32}{0.55}

\text{Weight of pinto beans bag}=2.4

Therefore, the weight of pinto beans bag is 2.4 pounds.

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

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
