I just had this question choose "d" hope it helps
There's 4oz left
75%=3/4
so 3/4 of 16oz (one pint) is 4.
Area= width * length
w=1/2 length
Area+ 128 sqr ft
Plug in the information you know into the Area formula.
128 ft2= w * l
128 ft2= (1/2 l)(l)
128 ft2=l/2
multiply both sides by 2 to get rid of the fraction
256 ft2 = l
take the square root of 256
16=length in feet
1/2length = width = 8 feet
Hope this helps! :)
Answer:
Perpendicular
<em />
Step-by-step explanation:
Given




Required
Is AB and CD parallel?
First, we need to calculate the slope (m) of AB and CD

For AB:


So:





For CD:


So:




For Lines to be parallel, the slope must be equal:
i.e. 
This condition is not true because:

For Lines to be perpendicular, the slope must be:

This implies:



<em>Hence, the lines are perpendicular</em>
