Robert, Julie, and Erin went to a cafe on a weekend. Their shared bill came to $25. Each person gave the server a $10 bill. The server took
this $30 and brought back five $1 bills in change. Each person took $1
back, leaving the rest, $2, as a tip for the server.
As he walked away from the cafe, Robert thought, "Wait—this doesn't
make sense. Since I put in $10 and got $1 back, I wound up paying $9.
So did Julie and Erin. Together, we paid $27. Then we left a $2 tip. That
makes $29 total. And yet we originally gave the waiter $30. Where did
the extra dollar go?"
Think about the situation and about Robert's question. Do you agree
that the numbers didn't add up properly? Explain your reasoning on the
next slide.

step-by-step explanation:

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

see below

step-by-step explanation:

x+2> 6

subtract 2 from each side

x+2-2 > 6-2

x > 4

there is an open circle at 4 since is it is greater than and the line goes to the right
