Answer:
Step-by-step explanation:
Just multiply the sides. For example, the roses take 8x4=32 feet. if we want to know the area of Zinnias, we multiply the sides 8x12 and remove the roses, which would be 8x12-32=96-32=60 for the Zinnias.
For a)
The roses take 8x4
Zinnias take 8x12 - roses
Snapdragons take 16x12 - roses - zinnias
Petunias take 16x20 - snapdragons - zinnias- roses
b) The entire area of the garden is 20x16=320 square feet
The area of the Zinnias(including roses) is 8x12 = 96 square feet
To get the percent, we divide the smaller number by the bigger number and multiply by 100 or in practice 96/320x100=30%
c) Let's see the progression here. The width progresses in the first rectangle by four 8 to 12, then again by four 12, 16 and again by four 16 to 20, which means that the next rectangle would have a width of 20+4=24. Doing the sale analysis for the height, we get that the increase is with 4 feet at a time or the new rectangle would have a width of 24 and height of 20, which means a total area of 480 feet. We have to subtract all other rectangles or the new area would be 480 - (20x16) = 160 square feet
6pi is the answer i believe
It is 8.5
cause it is the answer of the pie
and 3/8 is .10%
Let's solve ~
Now, move all like terms aside :
Add the like terms ~
Answer:
The line of sight distance is 1285.58 feet.
Step-by-step explanation:
The situation is illustrated in the figure attached.
From the figure we see that the altitude difference of the planes and the distance between them form a right triangle with one angle of 40° .
The line of sight between the two planes is the hypotenuse of the triangle.
The altitude difference of the planes is
Therefore, if we call 
the line of sight distance, from trigonometry we have
Therefore, the line of sight distance (x) is 1285.58 feet.
