Well we can find the perimeter by using the formula P=2L + 2W
P=2(30) + 2(18) P=60+36 P=96
I believe we can divide the perimeter by 18 to find the total amount of lights needed.
96÷18=5.333333
So we know at least 5 lights are needed.
I'm not sure if I'm correct, but I hope this helped anyways :)
Answer:
McCoy should plant soybeans
Step-by-step explanation:
Thinking process:
Let the two crops be corn and soybeans as indicated.
The profit margin for corn will be $ 30 000. However, the loss will be:
$ 35 000 - $ 30 000 = $ 5 000
For the soybean, the profit margin will be $ 10 000.
The loss will be $ 5 000
The net balance will be given as: $ 5 000 - $ 10 000 = - $ 5 000. (This represents a gain)
Thus, soybean will be more profitable.
Answer:
645 m²
Step-by-step explanation:
This figure has four similar sloping sides, each of which is a triangle with base 15 m and height 14 m.
The formula for the area of a triangle of base b and height h is A = (1/2)(base)(height).
In this case, the area of each of the four triangles is
A = (1/2)(15 m)(14 m) = 105 m².
Since there are four such triangles, the total area of the triangular sides is 4(105 m²) = 420 m².
The area of the base is A = (15 m)² = 225 m²
Combining side area with base area, we get a total surface area of
A = 225 m² + 420 m² = 645 m²
Please note: I am not familiar with the "net" you mention. If you want a problem solved in a particular way, and can share the necessary tool or tools, please do so.
I would say 115
because the angles should add up to 180
so if you take 65 away from 180 = 115
that and its an obtuse angle so it need to be more than 90 but less than 180.
115 is my best guess
