Well to get to 32 hours and knowing for all 4 days, she worked the same number of hours.
All we have to do is multiply all these numbers by 4 to see which one is equal to 32.
6 * 4 = 28
10 * 4 = 40
8 * 4 = 32
4 * 4 = 16
c. is the correct answer
Just multiply the top number by the top number and the bottom numbers by the bottom numbers so
2/4 times 1/3=(2 times 1)/(4 times 3)=2/12
so to simplify, we find the ones exg 4/8=1/2 because 1/2 times 4/4=4/8 and 4/4 cancels out so
2/12=2/2 times 1/6
=1/6
12 pizzas because
3 pizzas for ever 2 sides
3/2
x/8
X=12.
Answer:
13
Step-by-step explanation:
Here's a method of finding the area of any polygon knowing its vertices. I'm using this parallelogram as an example.
Make a table like this (each vertex with its x- and y-coordinates):
Pt x y
A 3 6
B 6 5
C 5 1
D 2 2
A 3 6
Now multiply each x-coordinate by the y-coordinate on the line below and write it on the right side. Bold type shows the first multiplication.
x y
A 3 6
B 6 5 15
C 5 1 6
D 2 2 10
A 3 6 12
Now multiply each y-coordinate by the x-coordinate on the line below and subtract from each produce you already have. Do each subtraction. Bold type shows the first multiplication.
x y
A 3 6
B 6 5 15 - 36 = -21
C 5 1 6 - 25 = -19
D 2 2 10 - 2 = 8
A 3 6 12 - 6 = 6
Add all the differences.
x y
A 3 6
B 6 5 15 - 36 = -21
C 5 1 6 - 25 = -19
D 2 2 10 - 2 = 8
A 3 6 12 - 6 = 6
+____
-26
The area of the polygon is the absolute value of half of the sum of the differences.
area = |-26/2| = |-13| = 13
