Answer
370.2 inches^2
Step-by-step explanation:
find the mass of the circle by taking the radius ( 9) square it and times it by pi then divide it by 2. Add that with the (27 times 18) divided by 2.
19 4-cent stamps and 3 28-cent stamps should be used.
Given that Greg needs at least $ 1.60 in stamps to mail a package, and he has 28cent stamps and 4cent stamps, and he can use no more than twenty 4cent stamps as he only has one book left, to determine how many stamps to use should be made the following calculation, through a linear function:
- (0.04 x 20) + 0.28X = 1.60
- 0.80 + 0.28X = 1.60
- 0.28X = 1.60 - 0.80
- 0.28X = 0.80
- X = 0.8 / 0.28
- X = 2.85
- (3 x 0.28) + 0.04X = 1.60
- 0.84 + 0.04X = 1.60
- 0.04X = 1.60 - 0.84
- 0.04X = 0.76
- X = 0.76 / 0.04
- X = 19
Therefore, 19 4-cent stamps and 3 28-cent stamps should be used.

Answer: A
put x = 3 into f(x)=6x and you get f(x) = 18
Put x = 4 into f(x) and you get f(x) = 24
Subtract those two. 24 - 18 = 6
Also, f(x) = 6x it will always be 6 away from the next x you put into the equasion.
Or better said, it will be 6 more from 6x, because you are changing the x to X+1, hence,
6(x+1) = 6x + 6.
+6, it increases.
Answer:
-2x+10
Step-by-step explanation:
<u>Answer:</u> The value of 15th term is 0
<u>Step-by-step explanation:</u>
The nth-terms of an AP is written as 
where,
a = first term
n = number of term
d = common difference
5th tem will be = 
11th tem will be = 
15th tem will be = 
The given ratio between 5th and 11th term is 5 : 2
Taking the ratios:
Hence, the value of 15th term is 0
