Step-by-step explanation:

In order to find each one, you use the formula A=pi R², meaning you put the radius to the power of two(multiply it by itself) and then multiply that by pi. ex: 7.4×7.4= 54.76,

next 54.76×3.14=171.9, which is your answer. If it gives you the diameter of the circle, divide that by two to get the radius, and follow the steps from before. Ex: 2.24÷2=1.12, next 1.12×1.12=1.2544, next 1.2544×3.14=3.9, the answer.

answer)

3.9
0.2
0.5
171.9
115,735
1.5

It's D, because the mean doesn't matter as much if it's only taken in a small variability. The mean was selected from 25 random pages in the book, that is why it is right.

Aaron, Bonny and Connor are playing a game with cards.

professor190 [17]

Let the number of cards Aaron has : A

Given :

⊕ Bonny has twice as many cards as Aaron

⊕ Connor has 6 cards more than Bonny

⊕ Total cards : 101

⇒ Number of cards Bonny has : 2A

⇒ Number of cards Connor has : 2A + 6

⇒ Aaron cards + Bonny cards + Connor cards = 101

⇒ A + 2A + 2A + 6 = 101

⇒ 5A = 101 - 6

⇒ 5A = 95

⇒ A = 19

<u>Answer</u> : Aaron has 19 Cards

The function rule C = 40n + 210 relates the number of months n to cost in dollars C of a phone plan and budget phone. Make a tab

Viefleur [7K]

Answer:

Input - Output

2 - $290

12 - $690

24 - $1170

Step-by-step explanation:

Cost after n months:

The cost after n months is given by the following function:

$C(n) = 40n + 210$

After 2 months:

This is C(2). So

$C(2) = 40(2) + 210 = 80 + 210 = 290$

After 12 months:

This is C(12). So

$C(12) = 40(12) + 210 = 480 + 210 = 690$

After 24 months:

This is C(24). So

$C(24) = 40(24) + 210 = 960 + 210 = 1170$

Table:

Input - Output

2 - $290

12 - $690

24 - $1170
