Answer:
For any circle of radius r
The diameter of the circle = two times of the radius = 2r
And The Circumference= C = 2πr
14. If r = 8
So, d = 2r = 2 * 8 = 16 cm
C = 2πr = 2 * π * 8 = 50.27 cm (to the nearest hundredth.)
15. If d = 9 m
So, d = 2r
∴ r = d/2 = 9/2 = 4.5 m
And C = 2πr = 2 * π * 4.5 = 28.27 m (to the nearest hundredth.)
96 → B
substitute w = 12 into the equation D = 3w + 60
D = (3 × 12 ) + 60 = 36 + 60 = 96
Answer:
f(x) = 2x+5
Step-by-step explanation:
Given the arithmetic sequence shown
7,9, 11, 13, 15, 17,
THe nth term of the sequence is expressed as;
Tn = a + (n-1)d
a is the first term = 7
d is the common difference = 9-7 = 11-9 = 2
Substitute
Tn = 7 + (n -1)*2
Tn = 7 + 2n - 2
Tn = 2n + 5
Hence the required function is f(x) = 2x+5
Answer:

Answer:
$ 5,500
Step-by-step explanation:
Simple, 1 kg = 1000 grams, so, 250 grams is a quarter, just divide the $22,000 by 4 = $ 5,500
