Think of it this way:
You are trying to make a ratio to the months with thirty days and the ones who don't.
So,
there are 4 months a year with 30 days.
That means that there are 12-4= 8 months a year that are not 40 days.
It said the months to 30 days first in the problem.
4:8
Divide each side by 4, since both are divisible by 4.
1:2
For every one month of 30 days, there are 2 months that do not have 30 days.
1 to 2 is your answer.
I hope this helps!

So find the diameter which is the radius times 2
So 3x2= 6
6x 3.14(Pi)
=18.84 which a full circle and now divide by two
9.42 is the area of semi circle
Answer:
She will receive $24,000 after paying taxes
Step-by-step explanation:
This question can be solved using a rule of three.
20% of her money has to go to the state for taxes. So she will receive 100-20 = 80%. $30000 is 100% = 1. How much is 80% = 0.8?
$30000 - 1
$x - 0.8
x = 30000*0.8
x = 24000
She will receive $24,000 after paying taxes
(
)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

the thingummy is a trapezoid
we need to find AD and BC and XY
we already know that BC=

AD distance
A=5,8
D=21,0
x1=5
y1=8
x2=21
y2=0

so we have

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