Answer:
For your area models you would draw two rectangles and divide one into 2 equal sections, and the other one with 8 equal sections. You then shade 1 box out of the first triangle with 2 equal sides. Then you would shade 7 boxes on the rectangle with 8 equal sides. These diagrams would show you that 7/8 and 1/2 are not equivalent.
To find out what fractions are equivalent to 1/2 you would take 1/2 and times the numerator and denominator by the same number.
1/2*2/2= 2/4
2/4=1/2
1/2*9/9= 9/18
9/18=1/2
2/4 and 9/18 both equal 1/2
Hope this helps ;)
Note that each x value increases by 1 and y values also increases by 1
C is the correct option
Answer:
8 feet
Step-by-step explanation:
First, draw a picture. The pole is 22 feet tall. Katherine is 5.5 feet tall. She is 24 feet from the pole. The light from the top of the pole to the tip of her shadow forms two similar right triangles. The length of her shadow is x.
Now use similar triangles to write a proportion:
22 / (24 + x) = 5.5 / x
Cross multiply:
22x = 5.5 (24 + x)
Distribute:
22x = 132 + 5.5x
Combine like terms:
16.5x = 132
Divide:
x = 8
The shadow is 8 feet long.
Answer:
55°
Step-by-step explanation:
Since a||b
Then corresponding angles are equal
So 55 is correspondent to X
Therefore X=55°
