chloe is 5 feet 4 inches tall. There are 2.54 centimeters 1 inches . What is chloe hieght in centimeters?

5 feet 4 inches = 162.56 centimeters

5 feet and 4 inches= 64 inches

64 x 2.54= 162.56

162.56, or 163 if you have to round

Step-by-step explanation:

You have the conversion for centimeters to inches and know the conversion for inches to feet. First, you need to convert feet to inches in order to be able to convert inches to centimeters. Chloe is 5 feet, 4 inches. There are 12 inches in a foot, so 12 inches times 5 feet is 60 inches. Add the leftover 4 and Chloe is 64 inches tall. All you have to do now is multiply that by 2.54, because thats how many centimeters are in one inch, and you get 162.56. Hope this helps, have an awesome day and brainliest always appreciated!

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
