If frank has 24 pennies 62 nickles 55 dimes 16 quarters and 19 fifty cent pieces how much money does he have

$22.34

Step-by-step explanation:

First we convert all the money to dollars.

1 penny = 0.01 dollar

24 pennies = 0.24 dollar

1 nickle = 0.05 dollar

62 nickles = 3.10 dollars

1 dime = 0.10 dollar

55 dimes = 5.50 dollars

1 quarter = 0.25 dollars

16 quarter = 4.00 dollars

1 fifty cent = 0.50 dollars

19 fifty cent pieces = 9.50 dollars

Total money = $0.24 + $3.10 + $5.50 + $4.00 + $9.50

                    = $22.34

He have $22.34.

step-by-step explanation:

your welcome : )

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
