Answer:
Area = 15.36 ft
Step-by-step explanation:
First find the area of the dotted line triangle using the formula: base x height x 1/2, which would be 1.2ft x 12.8 x 1/2 = 7.68ft.
Next, add another triangle at the top, mirroring the shown triangle, of the parallelogram.
Then, find the area of the shape as though it were a rectangle. (base x height) - 2.4 x 12.8 = 30.72.
Next, multiply the area of the invisible triangle by 2, 7.68 x 2 = 15.36ft
and Finally, subtract the area of the rectangle shape of the the sum of the two invisible triangles, 30.72 - 15.36 = 15.36ft
The area of the parallelogram is 15.36 ft.
Answer:
(5,0) and (1,0)
Step-by-step explanation:
you can set each factor equal to zero:
-x + 5 = 0
-x = -5
x = 5
x - 1 = 0
x = 1
Well if you divide 226/2 you will get 113. o do 113x8= and you will get 904. So the plane will travel 904 miles in 8 hours!
Answer:
1.25
Step-by-step explanation:
original price + markup = retail
The markup = original * markup percentage
original + original * markup percent= retail
Factor out the original
original( 1+ markup percent) = retail
original ( 1 + 60%) = 2
Change to decimal form
original ( 1+ .60) = 2
original ( 1.60) = 2
Divide each side by 1.6
original = 2/1.6
original =1.25
Set up a proportion, cross multiply, and solve.
![\frac{7.2}{4} =\frac{x}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B7.2%7D%7B4%7D%20%3D%5Cfrac%7Bx%7D%7B3%7D%20%20%20)
3(7.2) = 4(x)
21.6 = 4x
5.4 = x
