Formula: circumference = 2πr

Formula: Area = πr²

Given circumference = x and area = y and x = 2y

2πr = 2πr²

Divide by 2πr on both sides:

r = 1

Answer: r = 1

I believe it would be B. linear because it would depend on how much of a decrease the monthly rate changes and based on that the five hundred would change per every dollar (new customers=500x+5000) x being $decrease in monthly rate

How many 1/6 cup serving of rice and in 2/3 cup of rice

jok3333 [9.3K]

Answer:

4 serving cups

Step-by-step explanation:

Given

$Serving\ cup = \frac{1}{6}$

$Rice\ cup = \frac{2}{3}$

Required

The number of serving cup (n)

This is calculated by dividing the rice cup by the serving cup

$n = \frac{Rice\ cup}{Serving\ cup}$

$n = \frac{2/3}{1/6}$

Rewrite as:

$n = \frac{2}{3} \div \frac{1}{6}$

Change to multiplication

$n = \frac{2}{3} * \frac{6}{1}$

$n = \frac{12}{3}$

$n=4$
