Answer:
Trapezoid Median Theorem
Step-by-step explanation:
The Trapezoid Median Theorem says ...
The median of a trapezoid is parallel to each base and the length of the median equals one-half the sum of the lengths of the two bases.
__
That's the theorem that would seem to be applicable here.
Step-by-step explanation:
6-6x=108
-6 from both sides
-6x=102
divide by -6 on both sides
x= -17
4x - y = 2
y = 4x
and 4x + y = 6
As all three of their gradients have been inverted (-1/m), meaning they are perpendicular.
X= sandwiches
y= bottles of water
QUANTITY EQUATION
x+y= 200
COST EQUATION
$3x + $0.75y= $318.75
STEP 1
solve for one variable in quantity equation and substitute in cost equation
x+y= 200
subtract y from both sides
x= 200-y
STEP 2
substitute 200-y in for x
$3x + $0.75y= $318.75
3(200-y) + 0.75y= 318.75
600 - 3y + 0.75y= 318.75
combine like terms
600 - 2.25y= 318.75
-2.25y= -281.25
divide both sides by -2.25
y= 125 number of water bottles
STEP 3
substitute y=125 in either equation
x+y= 200
x + 125= 200
x= 75 sandwiches
ANSWER: There were 75 sandwiches and 125 bottles of water.
Hope this helps! :)
An expression in expanded form for the decimal that shows more than 0 hundredths is 19.31
<h3>How to write an expression in expanded form for the decimal that shows more than 0 hundredths.</h3>
The time is given as:
Time = 19.305
The hundredth in the above number is 0
So, to write an expression in expanded form for the decimal that shows more than 0 hundredths;
We simply approximate 19.305
So, we have:
Time = 19.31
Hence, an expression in expanded form for the decimal that shows more than 0 hundredths is 19.31
