Answer:
70 routes are possible
Step-by-step explanation:
Here, we want to find the number of possible routes
Since samples must be taken at four locations from a possible 8; then the number of possible routes will be 8 C 4
= 70 routes
Answer:
sum of interior angles of the octagon is 1080 degree
Step-by-step explanation:
forluma:
(n-2)*180 degree
since octagon has 8 sides
(8-2)*180 degree
6*180
1080 degree
Answer:
42 ft²
Step-by-step explanation:
First of all, who makes a hole in this shape?
Anyways,
You're going to want to split the figure into multiple different shapes. We already have a triangle, so I would split the remaining shape into a rectangle and trapezoid.
We can find the area of the triangle easily with the equation 1/2(bh)
So
1/2(2 · 3)
1/2(6)
3
So the triangle is 3 ft²
Now we can find the area of the rectangle.
The measurements will be 3 and 7. It's just base x height so it'll be 21 ft²
Finally the trapezoid.
Base 1: 6
Base 2: 3
Height: 4 (11-7)
Formula: 1/2h (b1 + b2)
1/2 · 4 (6+3)
2(9)
18 ft²
Now just add them together:
3+21+18=42
Hence, your answer is 42 ft²
Answer:

Answer:1
Step-by-step explanation:the y is a place holder instead of the digit 1 because there is only one y. Whitch is the same reason why the 2 isn’t 2x because the 2 is a place holder for how many x there are. The problem is showing you how much value each place holders have. (x,y)
