Answer:
12546
Step-by-step explanation:
9.5% = 0.95 = 95
12,640 - 95 = 12546
If the slope of AB = CD and BC = AD it's a parallelogram:
Slope of AB = 6+1 / -9+5 = -7/4
CD = -2-5 / 3+1 = -74
These are equal.
BC = 5-6 / -1 +9 = -1/8
AD = -2 +1 / 3+5 = -1/8
These are also equal so it is a parallelogram.
Now to find if the diagonals are perpendicular find the slope of the perpensicular points:
AC = 5 +1 / -1 +5 = 6/4 = 3/2
BD = 6+2 / -9 -3 = 8/-12 = -2/3
Because BD is the reciprocal of AC, this means they are perpendicular.
And because AB is not perpendicular to AD ( AB and AD are not reciprocals) it is a rhombus.
25 to 75 in lowest terms:
25:75 = 1:3
Answer:
you could use the formula
Step-by-step explanation:
That is x = -b<u>+</u>√b^2 - 4ac/2a
where ur x is
x= -b+√b^2-4ac/2a or
x= -b-√b^2-4ac/2a
Answer:
8L/2days = 4L/day
4L/day x 7 days = 28L
