(
)we need 3 equations
1. midpoint equation which is (
) when you have 2 points
2. distance formula which is D=
3. area of trapezoid formula whhic is (b1+b2) times 1/2 times height
so
x is midpoint of B and C
B=11,10
c=19,6
x1=11
y1=10
x2=19
y2=6
midpoint=(
)
midpoint=(
)
midpoint= (15,8)
point x=(15,8)
y is midpoint of A and D
A=5,8
D=21,0
x1=5
y1=8
x2=21
y2=0
midpoint=(

midpoint=(

midpoint=(13,4)
Y=(13,4)
legnths of BC and XY
B=(11,10)
C=(19,6)
x1=11
y1=10
x2=19
y2=6
D=

X=15,8
Y=(13,4)
x1=15
y1=8
x2=13

the thingummy is a trapezoid
we need to find AD and BC and XY
we already know that BC=
and XY=
AD distance
A=5,8
D=21,0
x1=5
y1=8
x2=21
y2=0
D=

D=
AD=
so we have
AD=
BC=
XY=
AD and BC are base1 and base 2
XY=height
so
(b1+b2) times 1/2 times height
(
) times 1/2 times
=
(

=80
=252.982
X=(15,8)
Y=(13,4)
BC=
XY=
Area=80
square unit or 252.982 square units
Answer:
1.125 or 9/8
Step-by-step explanation:
5/8 is .625 and 3/6 is .5 so .625+.5=1.125
Answer:
The original price is $650
Step-by-step explanation:
There's an actual algebra method for this, but this is my method because I find it way easier to remember.
Since the most you can discount out of an item is 100% (well, it's considered free then) let's subtract 100 - 34, which is 66.
Now, turn it into a decimal because it makes the numbers easier- 0.66.
Since when you're finding the discount of an original price, you multiply the original price by the discount- instead for finding the original price for a discounted item we divide $429 by 0.66 instead, since when you divide a number by another number that's under 1 the quotient is a larger number.
So, 429 ÷ 0.66 = 650.
Therefore, the original price of the $429 sale price for a 34% discount is $650.
Answer:
The correct answer is C, as growth on stock E is bigger from the growth of stock B
Step-by-step explanation:
In order to resolve this problem, we must have in mind that the negative numbers are smaller when they are more distant from 0, and that positive numbers are bigger when they are more distant from 0. So, the biggest number of growth is the one that is more distant from 0.
The correct answer is C, as growth on stock E is bigger from the growth of stock B.
