Answer:
a. 64, 128, 256 (geometric)
b. 11, 13, 15 (arithmetic)
c. 53, 61, 69 (arithmetic)
Step-by-step explanation:
(a) Each term is twice the previous term. so it is geometric with a common ratio of 2
(b) The difference between each term is 2. So it is arithmetic with a common difference of 2
(c) The difference between each term is 8. So it is arithmetic with a common difference of 8
10 ^ -3 = 0.001
10 ^ -2 = 0.01
10 ^ -1 = 0.1
10 ^ 0 = 0
10 ^ 1= 10
10 ^ 2 = 100
10 ^ 3 = 1000
12x14 is 168 12x2=24 14x2=28 24x28=672
672/168=4 The area is affected by a scale factor of four. Because the label of area is the unit squared, you just square the number that the dimensions are being multiplied by.
Answer:
40.56 ft
Step-by-step explanation:
The perimeter of a circle is equivalent to 
, where r = radius. Therefore, the perimeter of a semicircle should be 
In this case, we're given the diameter of the semicircle as 8, so we divide the diameter by 2 and get the radius as 4. Now, let's solve the circumference of the semicircle.
Now, we're given the lengths of the rectangle as 8, 10, and 10. The perimeter of the rectangle (excluding the inner side) is 28.
28 + 12.56 = 40.56
Therefore, the perimeter is 40.56 ft.
